D would likely have the lowest (coldest) temperature because it lost the least amount of kinetic energy, and it is likely that any kinetic energy turned into thermal energy (law of conservation of energy).

Answer:

b)   O₂

d)   CH₄

Explanation:

In a chemical equation, the <u>reactants</u> are the substances that are written on the <u>left side</u>. The reactants react to produce the products. On the right side, the products are written.

The arrow => is used to separate the reactants from the products.

To the left of the arrow, you can see this written:

CH₄ + 2O₂

The plus sign + is used to separate each reactant.

In 2O₂ you can ignore the big 2 because it is a coefficient, which is written to balance the equation.

The reactants are CH₄ and O₂

How many moles of HCl are in 30.00mL of a 0.1000M HCl solution? A. 0.003000mol. B. 300.0mol C. 0.03000mol D. 3.000mol
Katyanochek1 [597]

Given the volume of HCl solution = 30.00 mL

Molarity of HCl solution = 0.1000 M

Molarity, moles and volume are related by the equation:

Molarity = \frac{Moles of solute}{Volume of solution (L)}

Converting volume of HCl from mL to L:

30.00 mL * \frac{1 L}{1000mL}=0.030000 L

Calculating moles of HCl from volume in L and molarity:

0.03000 L * \frac{0.1000mol}{L}= 0.003000 mol HCl

The final moles would be reported to 4 sig figs. So the correct answer will be 0.03000 mol HCl

Correct option: C. 0.03000mol
