How many grams of calcium carbonate were used if you drew the periodic table on the sidewalk using
german

Based on the data provided, there are 25 g of calcium carbonate in 1.505 × 10^23 atoms.

<h3>What is the moles of calcium carbonate in 1.505 × 10^23 atoms of calcium carbonate?</h3>

The mole of a substance can be calculated as follows:

  • Moles of substance = number of particles/6.02 × 10^23

Moles of calcium carbonate = 1.505 × 10^23/6.02 × 10^23

Moles of calcium carbonate = 0.25 moles

The mass of calcium carbonate in 0.25 moles is calculated as follows:

  • mass = moles × molar mass

molar mass of a calcium carbonate = 100 g/mol

mass of calcium carbonate = 0.25 × 100 = 25 g.

Therefore, there are 25 g of calcium carbonate in 1.505 × 10^23 atoms.

Which is the correct equation for the reaction of magnesium with hydrochloric acid to produce hydrogen and magnesium chloride?
zimovet [89]
Answer is: a. Mg + 2HCl → H₂ + MgCl₂.
Reduction hald reaction: 2H⁺ + 2e⁻→ H₂.<span>
Oxidation half reaction: Mg</span>⁰ → Mg²⁺ + 2e⁻.
In this chemical reaction, magnesium lost two electrons (oxidation, change oxidation number from 0 to +2) and hydrogen gain that two electrons (reduction, change oxidation number from +1 to 0).
