a
(1 point)
O The substance with a pH of 2.0 would have 100 times as many hydrogen ions per volume of water.
o The substance with a pH of 4.0 would have 100 times as many hydrogen ions per volume of water.
O The substance with a pH of 4.0 would have twice as many hydrogen ions per volume of water.
O The substance with a pH of 2.0 would have twice as many hydrogen ions per volume of water.

Answers

Answer:

The answer is the first one.

Explanation:

The lower a pH level the higher the the number hydrogen ions present in the acid's container.

ph = - log(H)

4 = - log(H)

- 4 = log(h)

10^-4 = H+

1 * 10^-4 = H +

ph = - log(H)

ph = 2

- 2 = log(H)

10^-2 = H

1*10^-2 = h

Something the power - 2 is 100 times greater than something with the power of -4

Voltage ______
Question 1 options:


causes current


pushes free electrons around a circuit


is measured in Volts


all of the choices

Answers

The answer is: D - all of the above.

Explanation:

When a voltage source is connected to a circuit, the voltage will cause a uniform flow of charge carriers through that circuit called a current.

Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.

In brief, voltage = pressure, and it is measured in volts (V).

1. Calculate the grams of solute contained in 450. mL of a 0.075 M solution of CuCl2.

Answers

Answer:

4.6 grams CuCl2

Explanation:

Since molarity is a representation of moles per liter, we first want to convert 450. mL to liters:

450. mL * 1 L/1000 mL = 0.450 L

Now, we can use this number and the molarity to figure out the answer:

0.075 M means that for every liter, there is 0.075 moles of CuCl2.  Thus, we can multiply the amount of moles per liter by the number of liters of solution.

0.075 moles/1 L * 0.450 L = 0.03375 moles

Then, we need to round this to the appropriate number of significant figures, which gives us:  

0.034 moles CuCl2

Next, we can find the grams of CuCl2.  To do this, we first need to find the molar mass of CuCl2.  The molar mass of Cu is 63.546 g/mol and the molar mass of Cl is 35.453 g/mol, so the molar mass of CuCl2 is as follows:

(1 Cu * 63.546) + (2 Cl * 35.453) = 134.45 g/mol CuCl2

Now, we can multiply the grams per mole by the number of moles of CuCl2 in our solution:

134.45 g/mol * 0.034 moles = 4.5713 grams = 4.6 grams CuCl2, rounded to the appropriate significant figures.

A 23.6 g sample of an unknown gas occupies a volume of 12.0 L at standard temperature and pressure. What is the molecular mass (molar mass) of this gas?

Answers

The molecular mass (molar mass) of this gas is equal to 44.08 g/mol.

Given the following data:

Mass = 23.6 gramsVolume = 12.0 LitersStandard temperature = 273 KStandard pressure = 1 atm.

To calculate the molecular mass (molar mass) of this gas, we would use the ideal gas law equation;

[tex]PV=\frac{MRT}{MM}[/tex]

Where;

P is the pressure.V is the volume.M is the mass of substance.MM is the molar mass of a substance.R is the ideal gas constant.T is the temperature.

Making MM the subject of formula, we have:

[tex]MM = \frac{MRT}{PV} \\\\MM = \frac{23.6\times 0.0821 \times 273}{1 \times 12}\\\\MM = \frac{528.95}{12}[/tex]

Molar mass, MM = 44.08 g/mol.

Two arms, each known as a Dorsal Horn, are formed by the core grey matter at the back of the spinal cord. In the image, the region labeled “ A “ is called the Dorsal Horn. Therefore, option B is correct.

What is dorsal horn ?

One of the gray longitudinal columns discovered inside the spinal cord is the dorsal horn. Through the dorsal roots of the spinal nerves, it predominantly serves as the end of primary afferent fibers.

A complex network of excitatory and inhibitory interneurons, as well as projection neurons, make up the dorsal horn, which serves as an intermediary processing center for this information. It transmits the processed somatosensory information from the spinal cord to the brain.

The cell bodies of sensory neurons are located in the dorsal horns. The ventral horns are two arms of central grey matter that are found at the front of the spinal cord.

Thus, option B is correct.

What is the empirical formula of a compound that is 27.3% carbon, 9.10% hydrogen and 63.6% nitrogen by mass?

Answers

Explanation:

Mass ratio C : H : N = 27.3 : 9.10 : 63.6

Mole ratio C : H : N = 27.3/12: 9.10/1 : 63.6/14

( Divide the mass ratio by their molar masses to find the ratio between moles)

Mole ratio = 2.275 : 9.10 : 4.54

= 2.275/2.275 : 9.10/2.275 : 4.54/2.275

= 1 : 4 : 2

Answer is CH4N2

The empirical formula of a compound is [tex]CH_4N_2[/tex]

What is an Empirical Formula?

The empirical formula of a chemical compound is defined as the simplest whole number ratio of the atoms present in a compound.

The empirical formula of a compound defines the simplest ratio of the number of different atoms present. The molecular formula gives the actual number of each different atom present in a molecule. The molecular formula is mainly used which is a multiple of the empirical formula.

Molecular Formula  = n × Empirical Formula

For above given example,

Mass ratio C : H : N = 27.3 : 9.10 : 63.6

Mole ratio C : H : N = 27.3/12: 9.10/1 : 63.6/14

( We divide the mass ratio by their molar masses to find the ratio between moles)

Mole ratio = 2.275 : 9.10 : 4.54 = 2.275/2.275 : 9.10/2.275 : 4.54/2.275

= 1 : 4 : 2

Thus, the empirical formula of a compound is [tex]CH_4N_2[/tex]

The bond is polar covalent because the difference in electronegativity is greater than 0.4, but  less than 1.7.

Electronegativity refers to the ability of an atom in a compound to attract the electrons of the bond towards itself. It is a periodic trend that increases across the period but decreases down the group.

The electronegativity difference between the two atoms as shown in the question is 1.55. This means that the bond is polar covalent because the difference in electronegativity is greater than 0.4, but  less than 1.7.

Answer:

The Law of Conservation of Mass states that the mass of the system must remain constant over time as the system's mass cannot change because energy is not created nor destroyed. To tell if a chemical equation meets this law, check to see if the number of atoms is the same on both sides of the chemical equation.

Reactant Side:

Product Side:

Remember, when counting the atoms in a equation the subscript is the number that represents the quantity of that specific atom. Subscripts are numbers that come after a symbol and below. If an element does not have a subscript, then it is understood that the subscript is 1.  The coefficent represents the quantity of molecules, the coefficient multiplies everything in the formula.
