Answer:
A. 1 liter of water at temperature 75°C
Explanation:
According to kinetic molecular theory average kinetic energy of molecules are directly proportional to absolute temperature.
the quantity of the sample does't depend on kinetic energy only temperature
does so the choice with highest temperature is the correct choice
∵ 1 liter water at 75°C has highest average kinetic energy per molecule
Answer:
pH = 4.4
Explanation:
pH = -log[H₃O⁺]
= -log(4.3 × 10⁻⁵)
pH = 4.37 = 4.4
I'm actually learning this in my chemistry class right now lol. Hope this helps though. :)
Answer:
Existence
Explanation:
Energy is required for anything to occur, without it there would be no 'causality' for things to change from one moment to the next.
Hope this helped!!!
There's nothing following?
<u>Answer</u>:
Charlie adjust the coefficients to make the number of atoms in the reactants the same as the number of atoms in the
<u>Explanation</u>:
Stoichiometric coefficients are the number that appears before the symbol in each compound or element in the equation of a chemical reaction. By rule, it is positive for products and negative for reactants. Stoichiometric coefficients help in describing the stoichiometry of a chemical reaction.
According to "law of conservation of mass" that states "total reactant's mass equals the overall mass of obatined from the product". Thus, Charlie would adjust coefficients to equalise the number of atom in reactants and products.
