Answer:
The correct option is
C) Trial 1 will have the same calculated empirical formula as trial 2.
Explanation:
The empirical formula is the formula of a chemical compound that states the simplest whole number ratio of each of the atoms included in the compound. It is obtained by dividing the mass of an element present in the compound by the element's molar mass to find the mole ratio of the elements. The obtained mole value for each element is then divided by the smallest number of moles obtained in the division.
By definition the composition and ratio of elements combined in a chemical compound is fixed, therefore trial 1 will have the same calculated empirical formula as trial 2.
Explanation:
A hydrogen atom is composed of a proton (including a neutron) and electron. In chemical reaction with Hydrogen, the atom can easily gain or lose its only electron in its 1s orbital shell to achieve stable electron configuration.
It can behave like alkali metals when it loses its valence electron in its outermost orbital shell in a reaction. An example is just like metals, it can react with non-metals like chlorine (to form HCl).
Hydrogen can also act as a non-metal and gain an electron in its outermost valence shell to achieve stable electron configuration of 1s². This way it can behave like a halogen. It can react with metals such as Sodium to form a NaH (Sodium Hydride).

Answer:
Total concentration of ions present in the final solution is 0.0726 M.
Explanation:
Mass of silver nitrate = 54.0 g
Moles of silver nitrate =
Volume of the solution made = V = 350.0 mL = 0.350 L
After dilution of 10.00 mL 0.9227 M solution.
Concentration of silver nitrate after dilution = 0.0363 M
Total concentration of ions present in the final solution:
