Answer:

47, 68, 47

Explanation:

Let's consider the following isotope: ¹¹⁵Ag.

If we look in the Periodic Table, the atomic number of Ag is 47, that is, silver has 47 protons.

Since ¹¹⁵Ag is neutral it must have the same number of protons that of electrons. Then, it also has 47 electrons.

The number 115 in ¹¹⁵Ag stands for the mass number, which is the sum of protons and neutrons. Then, the number of neutrons is:

p⁺ + n⁰ = 115

n⁰ = 115 - p⁺ = 115 - 47 = 68

The number of protons, neutrons, and electrons in ¹¹⁵Ag is: 47, 68, 47.

Which contains more molecules: 1.00 mol, H2O2, 1.00 mol C2H2, or 1.00 mol CO?
xenn [34]
A mole of any chemical compound contains the same number of molecules - about 6.022 × 10²³ molecules.
So, 1 mole of H₂O₂, 1 mole of C₂H₂ and 1 mole of CO contain the same number of molecules.

Which sample equation best illustrates the Law of Conservation of Mass?
lutik1710 [3]

Answer:

D . 20 grams reactant U + 3 grams reactant V → 23 grams product W

Explanation:

Law of conservation of mass states:

The mass of a closed system (As a reaction), is neither created or destroyed.

That is, the mass of reactants is equal to mass of products.

A. In reaction A 22g of reactants produce 9g of products. This reaction doesn't illustrates the law of conservation of mass.

B. 10g reactant produce 25g of products. This reaction doesn't illustrates the law of conservation of mass.

C. 19g of reactants produce 180g of products. This reaction doesn't illustrates the law of conservation of mass.

D. 23g of reactants produce 23g of products. -This is the reaction that best illustrates the Law of Conservation of Mass.
