Answer:
in H2So4 splits in 2 H+ and a
so42 -particle=3particle per mole.So2
moles H2So4 will result in 3*2=6moles
of molecules.
Look up chromium on periodic table.
It's atomic number is 24.
It gives number of protons in an element.
Since the atom is uncharged (no extra or subtracted electrons), the number of protons will equal the number of electrons.

because dogs don't do c,The owner trains the dog to do a,d and b is naturally learned
Answer:
B. It represents the change in enthalpy for the reaction.
Explanation:
The potential energy diagram for a chemical reaction shows its potential energy plotted against the reaction progress coordinate. The potential energy diagram shows how the potential energy of reactants and products vary as reactants are converted into products.
The potential energy of the system refers to energy stored in the chemical bonds of reactants and products. The difference between the potential energy of reactants and products is known as the enthalpy of reaction. This difference in potential energy may be positive or negative. A positive difference in potential energy implies an endothermic reaction while a negative difference in potential energy implies an exothermic reaction.
Answer:
The molarity of products is divided by the molarity of reactants.
Explanation:
