<u>1) determine which formula you are going to use.</u>

PV=nRT

<u>2) list your information.</u>

P = 101.325 kPa

V = 3.57 L

n = ?

R = 8.314 \frac{kPa\ L}{mol\ K}

T = 273.15 K

<u>3) rearrange your formula</u>

n=\frac{PV}{RT}

<u>4) solve.</u>

n=\frac{(101.325\ kPa)(3.57\ L)}{(8.314\frac{kPa\ L}{mol\ K})(273.15\ K) } \\\\n=0.1592845319

<em>n = 0.159 mol NH₃</em>

Which of the statement below states the negative impact did chemistry have on society through the production and use of chlorofl
9966 [12]
I think the correct answer from the choices listed above is option A. The statement that states a negative impact of chemistry on the society is that hazardous <span>coolants in refrigeration units were replaced. One example of this coolant is the </span><span>production and use of chlorofluorocarbons (CFCs) which replaced by more safer coolants.</span>

Calculate the pressure of the CO₂ (g) in the container at 425 K.
Elanso [62]

The pressure of the CO₂ = 0.995 atm

<h3>Further explanation</h3>

The complete question

<em>A student is doing experiments with CO2(g). Originally, a sample of gas is in a rigid container at 299K and 0.70 atm. The student increases the temperature of the CO2(g) in the container to 425K.</em>

<em>Calculate the pressure of the CO₂ (g) in the container at 425 K.</em>

<em />

<em />

Gay Lussac's Law

When the volume is not changed, the gas pressure is proportional to its absolute temperature

\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}

P₁=0.7 atm

T₁=299 K

T₂=425 K

\tt P_2=\dfrac{P_1\times T_2}{T_1}\\\\P_2=\dfrac{0.7\times 425}{299}=0.995 `atm

What kind of electrical charges do protons,electrons, and neutrons have?​
Vinil7 [7]

<em><u>Protons</u></em><em><u> = Positive Charge</u></em>

<em><u>Neutrons</u></em><em><u> = Neutral Charge/No Charge</u></em>

<em><u>Electrons</u></em><em><u> = Negative Charge</u></em>

<em>This one's simple: electrons have a negative charge, protons have a positive charge and neutrons — as the name implies — are neutral.</em>

<u><em>Protons</em></u>

<em>Elements are differentiated from each other by the number of protons within their nucleus. For example, carbon atoms have six protons in their nucleus. Atoms with seven protons are nitrogen atoms. The number of protons for each element is known as the atomic number and does not change in chemical reactions. In other words, the elements at the beginning of a reaction -- known as the reactants -- are the same elements at the end of a reaction -- known as the products.</em>

<em />

<em><u>Neutrons</u></em>

<em>Although elements have a specific number of protons, atoms of the same element may have different numbers of neutrons and are termed isotopes. For example, hydrogen has three isotopes, each with a single proton. Protium is an isotope of hydrogen with zero neutrons, deuterium has one neutron, and tritium has two neutrons. Although the number of neutrons may differ between isotopes, the isotopes all behave in a chemically similar manner.</em>

<em />

<u><em>Electrons</em></u>

<em>Electrons are not bound as tightly to the atom as protons and neutrons. This allows electrons to be lost, gained or even shared between atoms. Atoms that lose an electron become ions with a +1 charge, since there is now one more proton than electrons. Atoms that gain an electron have one more electron than protons and become a -1 ion. Chemical bonds that hold atoms together to form compounds result from these changes in the number and arrangement of electrons.</em>
