Answer:
NH3 and NH4+
Explanation:
NH4+ is the conjugate acid of the base NH3.
Answer:
See Explanation
Explanation:
The Law of Conservation of Matter as applied to chemical reactions says that matter is neither created nor distroyed, only changed in form. This implies that the mass of substances going into a reaction process must equal the mass of products generated during the reaction process.
Empirically,
∑ mass reactants = ∑ mass products
One can test this idea after balancing a chemical equation by determining the sum of formula weights of reactants and products; then compare. If reaction was properly balanced, the total mass reactants = total mass of products.
Example:
Combustion of Methane => CH₄(g) + 2O₂(g) => CO₂(g) + 2H₂O(l)
Equation Weights => 16amu + 64amu <=> 44amu + 36amu
Mass Reactants = Mass Products => 80amu <=> 80amu.

*amu = atomic mass units => sum of atomic weights of elements
We have that every gas satisfies the fundamental gas equation, PV=nRT where P is the Pressure, V is the volume of the gas, n are the moles of the gas, R is a universal constant and T is the Temperature in Kelvin. We have that PV/T=nR and during our process, the moles of the gas do not change (no argon enters or escapes our sample). See attached.
Because there is less friction on the marble floor.
