That depends. What kind of change are you talking about? But
Mass<span> through chemical </span>change<span> stays the same as well. Example: burning paper, the ash left behind is not all of the </span>mass<span> of the reactants, Carbon dioxide, and other </span>substances<span> also makeup</span>mass<span> but just is not seen
</span>
The one in the cupbard looses its CO2 first as its warmer so its solution has a lower solibility to the CO2 gas
at lower temperatures the CO2 has less energy to escape from the solution of soda as CO2 in a solution is unstable it wants to be released
hope that helps <span />
Answer:
Explanation: Traits are characteristics, such as its size or height and that comes from parents or other relatives.
Answer:
in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
Explanation:
Answer:
Explanation:
CH₃COOH + NaOH = CH₃COONa + H₂O .
42.5 mL of .115 M of NaOH will contain .0425 x .115 moles of NaOH
= 48.875 x 10⁻⁴ moles NaOH
It will react with same number of moles of acetic acid
So number of moles of acetic acid in 3.45 mL = 48.875 x 10⁻⁴
number of moles of acetic acid in 1000 mL = 48.875 x 10⁻⁴ x 10³ / 3.45 moles
= 1.4167 moles
= 1.4167 x 60 gram
= 85 grams .
So 85 grams of acetic acid will be contained in one litre of acetic acid.
