B & C
Explanation:
Because the forward reaction results in a positive change in enthalpy, this reaction is endothermic – it takes energy from the environment. Therefore, the forward reaction will be favored if there are an increase n temperatures
Forward and reverse reactions are usually balanced. Removing a product (C6H12O6 in this case) as it is formed, favors the forward's reaction. This is because the process that results in a reduction in pressure of the system is favoured in the reaction.
Answer: The molar mass of a single hydrogen atom is 1 g/mol.
Explanation: The molar mass of a hydrogen molecule is 2 x 1 g/mol = 2 g/mol. Likewise, a molecule of oxygen gas has the formula O2 .
Answer:
Fractional distillation is used for the purification of water as well as separating acetone and water.
Fractional distillation is used in several industries like oil refineries and chemical plants mainly for purification and separation of many organic compounds.
Answer:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
