Answer:

The atoms in the cup of coffee have more energy.

Explanation:

The difference between the hot cup of coffee and the piece of ice is their temperature. The hot cup of coffee has a higher temperature than the ice.

The relationship between the energy and temperature is a direct relationship. This means that higher temperature means higher kinetic energy and vice versa.

Since the hot cup of coffee has  a higher temperature, it means it also have the highest amount of energy. The correct option is;

The atoms in the cup of coffee have more energy.

Methane burns in the presence of oxygen to form carbon dioxide and water.
wlad13 [49]

Answer:

= 9.28 g CO₂

Explanation:

First write a balanced equation:

CH₄ + 2O₂ -> 2H₂O + CO₂

Convert the information to moles

7.50g CH₄ = 0.46875 mol CH₄

13.5g O₂ = 0.421875 mol O₂

Theoretical molar ratio CH₄:O₂ -> 1:2

Actual ratio is  0.46875 : 0.421875 ≈ 1:1

If all CH₄ is used up, there would need to be more O₂

So O₂ is the limiting reactant and we use this in our equation

Use molar ratio to find moles of CO₂

0.421875 mol O₂ * 1 mol CO₂/2 mol O₂=0.2109375 mol CO₂

Then convert to grams

0.2109375 mol CO₂ = 9.28114 g CO₂

round to 3 sig figs

= 9.28 g CO₂

                              2NH4ClO4 --------> N2 + Cl2 + 2O2 + 4H2O
from reaction         2 mol                              1 mol
given                     x mol                              0.10 mol

Proportion:
<u>2 mol NH4ClO4 </u>= <u>1 mol Cl2</u>
x mol  NH4ClO4   0.10 mol Cl2

x= (2*0.10)/1 = 0.20 mol NH4ClO4
