how does atomic radius affect coulombic attraction?

Answers

Answer 1
According to Coulomb's Law, as the atomic number increases within a series of atoms, the nuclear attraction for electrons will also increase, thus pulling the electron(s) closer to the nucleus.

A reaction begins with 130.5g of substance X and substance Y. How many grams of
substance X and Y are there at the end of the reaction?

A) not enough information provided
B) 100g
C) 65.25g
D) 130.5g

Answers

Answer:

130.5g

Explanation:

At the of the reaction, the combined mass of X and Y will be 130.5g.

The premise for this conclusion is based on the law of conservation of matter.

This law states that "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".

In essence, in a chemical reaction, there is no mass loss.

The amount of product in the reaction is expected to be the same as the amount of reactants used in the experiment. When we start with 130.5g then we should end with 130.5g

A gas-filled balloon having a volume of 1.00 L at 1.2 atm and 25°C is allowed to rise to the stratosphere (about 30 km above the surface of Earth), where the temperature and pressure are -23°C and 3.00 10-3 atm, respectively. Calculate the final volume of the balloon.

Answers

Answer: The final volume of the balloon is 335.6 L

Explanation:

To calculate the final volume of the balloon, we use the equation given by combined gas law:

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

where,

[tex]P_1[/tex] = Initial pressure = 1.2 atm

[tex]P_2[/tex] = Final pressure = [tex]3.00\times 10^{-3}[/tex] atm

[tex]V_1[/tex] = Initial volume = 1.00 L

[tex]V_2[/tex] = Final volume = ?

[tex]T_1[/tex] = Initial temperature = [tex]25^oC=[25+273]=298K[/tex]

[tex]T_2[/tex] = Final temperature = [tex]-23^oC=[-23+273]=250K[/tex]

Putting values in above equation, we get:

[tex]\frac{1.2atm\times 1.00L}{298K}=\frac{3.00\times 10^{-3}atm\times V_2}{250K}\\\\V_2=\frac{1.2\times 1.00\times 250}{298\times 3.00\times 10^{-3}}\\\\V_2=335.6L[/tex]

Hence, the final volume of the balloon is 335.6 L

What is the formula for Iron (III) Bromate

Answers

Answer:

[tex]\boxed {\boxed {\sf FeBr_3}}[/tex]

Explanation:

We can assume that this is a neutral compound, meaning the charges of the ions are balanced.

We are given: Iron (III) Bromide.

We want to find the chemical formula.

First, find the symbols of the elements.

Fe: Iron Br: Bromine

Next, find the charges on the ions.

The Roman Numeral 3 in parentheses (III). This indicates the iron cation has a charge of +3.

We need to balance out the charge of +3 with the bromine. Bromine can have a charge of +5, +1, and -1. Since we already have a cation (positive ion), bromine must be an anion (negative ion). We also know the charge must be negative to balance out the compound.

But, the charge is only -1. That would still leave the compound unbalanced. Therefore, we must have 3 bromine atoms to balance out the iron. The 3 will become a subscript.

So, put all the information together and write the formula:

FeBr₃

A chemical formula lists the constituent elements of a compound together with the number of atoms in each element's smallest unit, such as a molecule or formula unit. Here the formula for Iron (III) Bromate is FeBr₃.

A compound's chemical composition is symbolically represented by its chemical formula. Chemical formulas reveal the elements that make up a compound's molecules as well as the ratio in which their atoms combine to create those molecules.

The sorts of atoms and their numbers in an element or compound are described by a chemical formula. Each element's atoms are denoted by one or two distinct letters. a collection of chemical symbols indicating the constituent elements and their corresponding ratios.

What element is in period 6 with 2 valence electrons?

Answers

Answer:

Barium

Explanation:

I think that's the answer

The element in period 6 with 2 valence electrons is Barium.

The periodic table has been organized into periods and groups. The period is in an horizontal arrangement while group is vertical arrangement.

The elements that can be found in period 6 are Beryllium, Magnesium, Calcium, Strontium, Barium etc.

Elements in the same group have the same number of valence electrons. This means that elements in group 2 have 2 valence electrons.

Barium possess two valence electrons because it is in group 2 and it is also in period 6. Therefore, the element in period 6 with 2 valence electrons is Barium.

Oxygen has to bond to two other atoms so the C-O bond should be a double bond to fulfil both of their bonding rules.
Hydrogen can only bond to one other atom, therefore it cannot make a double bond so that bond must be a single bond. (Carbon there is also bonding to five atoms so changing it to a single bond will fulfil both of their bonding rules).

After her husbands death, she took control of her sons with great wisdom. Even though each one of them was prince and therefore capable of ruling by his own will, she made sure they never departed from the rules of the ancient Mongol laws of conduct. When her son, Gyk Khan, was raised to the throne, he and his brothers were the only princes who because of Bekis wise guidancewere found always to have acted according to the laws.

It was at the call of the master weavers and spinners of England that the steam engine was set to run the machines; then to furnish a blast so that coal might be used to cheapen the smelting of iron and steel so that more machines might be made; then to pump out the deepening mines so that more and more power to keep the machines running might be won.
