Answers

Potassium has a lower EN than Bromine.

EN Trends:

Decreases down the group but increases across a period.

Potassium is to the left of the periodic table while bromine is on the right, and according to the trends, Bromine will be bigger because EN increases across a period. This allows the nucleus to attract the bonding electrons more strongly.

Which models of the atom in task 1 are not supported by the results of the hydrogen gas experiment? For each of these models, explain the experimental results that the model would predict.

Answers

Answer:

Thomson  placed two magnets on either side of the tube, and observed that this magnetic field also deflected the cathode ray. The results of these experiments helped Thomson determine the mass-to-charge ratio of the cathode ray particles, which led to a fascinating discovery, minus the mass of each particle was much, much smaller than that of any known atom. Thomson repeated his experiments using different metals as electrode materials, and found that the properties of the cathode ray remained constant no matter what cathode material they originated from. From this evidence, Thomson made the following conclusions:

The cathode ray is composed of negatively-charged particles.

The particles must exist as part of the atom, since the mass of each particle is only ~1/2000 the mass of a hydrogen atom.

These subatomic particles can be found within atoms of all elements.

While controversial at first, Thomson's discoveries were gradually accepted by scientists. Eventually, his cathode ray particles were given a more familiar name: electrons. The discovery of the electron disproved the part of Dalton's atomic theory that assumed atoms were indivisible. In order to account for the existence of the electrons, an entirely new atomic model was needed.

After the first four games of a professional football season, three players scored a total of 80 touchdowns. Duke Johnson scored 14 of the touchdowns. Josh McCown scored 40% of the touchdowns. Andre Roberts scored the remaining touchdowns. How many touchdowns did Andre Roberts score?.

Answers

The number of touchdowns scored by Andre Roberts = 34 touchdowns

Given data :

Total number of touchdowns = 80

Number of players = 3

Determine the number of touchdowns scored by Andre Roberts

Player 1 ( Duke Johnson ) scored = 14

Player 2 ( Josh McCown ) scored = 40% of 80 = 32

∴  number of touchdowns scored by player 3 ( Andre )

  = 80 - ( 14 + 32 )

   = 80 - 46  = 34 touchdowns

Hence we can conclude that the number of touchdowns scored by Andre is 34 .

In one to two sentences, describe an experiment that would show that intramolecular forces (attractions between atoms within molecules) are stronger than intermolecular forces (attractions between molecules).

Answers

Answer:

If the molecules have similar molar masses and similar types of intermolecular forces, look for the one that is the most polar or that has the most electronegative atoms or the most hydrogen bonding groups. That one will have the strongest IMF's overall.

Explanation:

An experiment that would show that intramolecular forces are stronger than intermolecular forces will be heating a block of ice in a sealed container then allowing it to change to steam.

Intramolecular forces are the forces of attraction that hold atoms together within a molecule. Intramolecular forces require a high amount of energy to splits atoms or molecules in a chemical bonding.

Intermolecular forces are weaker forces of attraction that occur between molecules. They require lesser energy to splits molecules compared to intramolecular forces.

An experiment that show that intramolecular forces are stronger than intermolecular forces will be heating a block of ice in a sealed container then allowing it to change to steam.

In the process, the energy required to change the state from ice to steam water is more than intermolecular forces.

Thus, we can conclude that this experiment shows that the intramolecular forces are stronger than the intermolecular forces.

Calculating Heat during Phase Changes

question below in photo :)

Answers

Answer:

Q1= 9.42

Q2= 227 KJ

Q3= 31.4 KJ

Qt=269 KJ

Explanation:

First you have to find the heat needed to make ice at a temperature of -45 C to pass to a temperature of 0 C.

You're given the formula so all you have to do is replace by the data you're given (remember to make the Celsius, Kelvin by adding 273.15 to the Celsius since the magnitudes of temperature they're giving you in the constants are the Kelvin)

Q1= (2.093 J/gxK)(100 g)(45 K)

Q1=9418.5 J

Q1=9.4185 KJ≈9.42 Kj(you're asked to give your answer in KJ)

You know have to find the energy needed to liquify the ice, in other words you need to use the enthalpy of fusion to determine the energy that's being used, and since you have 100 grams of water, you only need to find the number of moles present in 100 grams of water by dividing the number of grams by the molar mass of water (18 g/mol) and then replace in the equation.

Q2=(5.56 mol)(40.7 KJ/mol)

Q2=227 KJ

You know have to find the energy needed to raise the temperature of water from 0 C to 75 C. You do the same thing as you did in the first step:

Q3=(4.184 J/gxK)(100 g/)(75K)

Q3=31380 J

Q3=31.38 KJ≈31.4 KJ

For the final step, you only add the Qs of each step:

9.42KJ+227KJ+31.4KJ= 267.82 KJ ≈ 267.8 KJ

Why do you use these procedures?

Well, you could simply have made a unique equation at first sight that involved the changes of temperature from -45 C to 75 C, but you have a phase change in the middle. Phase change keep temperature constant but they require heat from the surroundings in order to, in the case of ice, break the bonds that keep the molecules tight together.

This heat required from the surroundings is the Enthalpy of phase change, in this case enthalpy of fusion.

how to tell if an electron will make a cation or anion

Answers

A cation is a positive charged ion and a anion is a negatively charged ion. An electron will make a cation if it is lost and a anion if it is gained.

The etymology of the prefix cat- means the way down: so think of the sun setting down and losing light. Cat = losing electrons (Such as in a CAThode ray).

The etymology of the prefix -an means upwards. So think of the sun rising up and becoming brighter. An = gaining electrons and becoming overall more negative as electrons are negatively charged.

Calculate the density of sulfur dioxide gas (SO2) at 147°C and 29.9 kPa.

Answers

The density of the gas is obtained as  0.55 g/L.

We can find the density of the gas using the relation;

PM = dRT

P = pressure of the gas

M = molar mass of the gas

d = density of the gas

R = gas constant

T = temperature

Now;

P = 29.9 kPa

R = 8.314 L·kPa mol·K.

T =  147°C + 273 = 420 K

d = ?

M = 64 g/mol

Substituting values;

d = PM/RT

d =  29.9 kPa ×  64 g/mol/ 8.314 L·kPa mol-1K-1 420 K

d = 1913.6/3491.88

1. What is the molar mass of NaOH?


2.How many atoms are in 3.35 moles of Aluminum?


3.How many moles of CO2 gas are in a 101.25 L container filled with CO2 gas?


4.What is the mass of 13.7 moles of N2 gas?


5.How many moles are in 78.5 molecules of CaCO3?

Answers

Answer:

1) Molar mass of NaOH can be calculated by taking the atomic mass values in the periodic table. Na (Sodium) = 22.98g/mol, O (Oxygen) = 16g/mol, H (Hydrogen) = 1.01g/mol

Add all the the mass values together for NaOH's molar mass, so (22.98 + 16 + 1.01) = 39.99 or round it to 40g/mol

2) To find the atoms from the moles, you just multiply Avogadro's number (6.02 x 10^23) by the moles.

So 3.35 x (6.02 x 10^23) = 2.0167 x 10^24 atoms are in 3.35 moles of aluminum

3) If the question is asking under standard temperature and pressure, we know that if we divide the volume by the molar volume of a gas (which is 22.7 in standard temperature and pressure), we can get the moles.  

So 101.25L / 22.7 = 4.46 mol

4) We know that to find the moles, it is the mass divided by the molar mass. If we rearrange the equation to solve for mass, we have to multiply the moles by the molar mass to get there.

Nitrogen's (N) molar mass on the periodic table is 14g/mol, but since Nitrogen is a diatomic element, it would be N2 by itself. So multiply 14 by 2, which will give you 28g/mol. N2's molar mass is 28g/mol.

Now you multiply 13.7 moles by 28g/mol, which will give you 383.6g

5) Now here I think you may have wrote the question wrong. Molecules would be at a way higher number than just 78.5, so I'm first just going to assume you meant 78.5g.

To get the moles from mass, you divide the mass of the compound by its molar mass. Molar mass of CaCO3 can be just calculated using the atomic mass values for each element in the compound (Ca is 40.07g/mol, C is 14g/mol, O3 would be 16 x 3 g/mol or just 48g/mol) and then adding them all together (40.07 + 14 + 48 = 102.07) which would give us 102.7g/mol.

Now, just divide the mass 78.5g by the molar mass 102.7g/mol

78.5/102.7 = 0.764 moles

Now on the offchance that you were actually referring to molecules, and you accidentally typed a different number doing this, you can find out the moles from the molecules by just dividing the number of molecules you have with avogadro's number (6.02 x 10^23)

So it would look something like this:

molecules of CaCO3 / 6.02 x 10^23
