Given the reaction: 4 NH3(g) + 5 O2(g) → 4 NO (g) + 6 H2O When 1.20 mole of ammonia reacts, how many moles of water are produced?
Answer:
When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.
Explanation:
The balanced reaction is:
4 NH₃(g) + 5 O₂(g) → 4 NO (g) + 6 H₂O
By stoichiometry of the reaction, the following amounts of moles participate in the reaction:
NH₃: 4 moles O₂: 5 molesNO: 4 molesH₂O: 6 molesThen you can apply the following rule of three: if by stoichiometry 4 moles of ammonia produce 6 moles of water, 1.2 moles of ammonia will produce how many moles of water?
[tex]moles of water=\frac{1.2 moles of ammonia*6 moles of water}{4 moles of ammonia}[/tex]
moles of water= 1.8 moles
When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.

Create the Equation: How many grams of Aluminum Chloride would be made from 42.7 L of Chlorine gas at STP reacting with 50.0 g of Aluminum?
Answer: 169.3 g of [tex]AlCl_3[/tex] will be produced
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
moles of [tex]Al[/tex]
[tex]\text{Number of moles}=\frac{50.0g}{27g/mol}=1.85moles[/tex]
moles of [tex]Cl_2[/tex]
According to ideal gas equation:
[tex]PV=nRT[/tex]
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 42.7 L
n = number of moles = ?
R = gas constant =[tex]0.0821Latm/Kmol[/tex]
T =temperature =[tex]273K[/tex] (at STP)
[tex]n=\frac{PV}{RT}[/tex]
[tex]n=\frac{1atm\times 42.7L}{0.0820 L atm/K mol\times 273K}=1.90moles[/tex]
[tex]2Al+3Cl_2\rightarrow 2AlCl_3[/tex]
According to stoichiometry:
3 moles of [tex]Cl_2[/tex] reacts with = 2 moles of aluminium
Thus 1.90 moles of [tex]Cl_2[/tex]reacts with= [tex]\frac{2}{3}\times 1.90=1.27[/tex] moles of aluminium
Thus [tex]Cl_2[/tex] is the limiting reagent as it limits the formation of product.
As 3 moles of [tex]Cl_2[/tex] give = 2 moles of [tex]AlCl_3[/tex]
Thus 1.90 moles of [tex]Cl_2[/tex] give =[tex]\frac{2}{3}\times 1.90=1.27moles[/tex] of [tex]AlCl_3[/tex]
Mass of [tex]AlCl_3=moles\times {\text {Molar mass}}=1.27moles\times 133.34g/mol=169.3g[/tex]
Thus 169.3 g of [tex]AlCl_3[/tex] will be produced from the given masses of both reactants.
If a 28.0 L balloon with a temperature of
25 °C is cooled in a refrigerator, what will
be the volume of the balloon be when it
reaches 5 °C?
Answer:
5.6 L
Explanation:
We can apply Charles' Law here since our pressure is constant (will not change inside the refrigerator) and we are relating change in volume with change in temperature:
V₁ / T₁ = V₂ / T₂ where V₁ and T₁ are initial volume and temperature, and V₂ and T₂ are final volume and temperature. Let's plug in what we know and solve for the unknown:
28.0 L / 25 °C = V₂ / 5 °C => V₂ = 5.6 L
5.6 L is our new volume (at 5 °C).

Why is methanol written as ch3oh instead of ch4o?
Answer: Here comes the role of another formula, which we refer to as the structural formula and that is CH3OH for methanol. The structural formula gives us an additional information that carbon is attached to three hydrogen atoms and one oxygen atom.

What do you think happens to the bonds between atoms when substances melt?
Answer:
As a substance melts, and goes from a solid to a liquid state, the kinetic energy of the molecules increases, and the molecules move faster, and they separate further and further away from each other. The intermolecluar forces holding the molecules together become weaker. This is why a liquid can take fill the shape of its container, whereas a solid has a fixed shape.

Why might the ability to produce three-dimensional images of organs be helpful in diagnosing a patient's ailment?
Answer:
Explanation: The body is largely composed of water molecules. Each water molecule has two hydrogen nuclei or protons. MRI takes advantage of the high prevalence of hydrogen in the body and the magnetic properties of the proton in a hydrogen atom. Hydrogen atoms induce a small magnetic field due to the spin of this atom's proton.
