Answer:
Volume also reduced to half
Explanation:
Volume and absolute temperature are directly proportional to each others
<span>pH scale is used to determine how acidic, basic or neutral a solution is.
pH can be calculated using the Hydrogen ion concentration.
pH is calculated using the following formula
pH = -log [H</span>⁺<span>]
[H</span>⁺<span>] can be calculated knowing the pH
[H</span>⁺<span>] = antilog(-pH)
[H</span>⁺<span>] = 1.32 x 10</span>⁻¹⁰<span> M</span>
Answer:
<h2>0.58 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
volume = 15 mL
mass of object = 8.7 g
We have
We have the final answer as
<h3>0.58 g/mL</h3>
Hope this helps you
The answer is TRUE.
If the Energy is on the left, then the problem is true. If it is on the right then it would be negative, false, and considered as exothermic.
Endothermic reaction = the products are higher in energy than the reactants.
Exothermic reaction = a chemical reaction that releases energy by light or heat.
