Using the balanced chemical equation below, calculate the moles of carbon dioxide, CO2, produced by the complete decomposition of 1.75 moles of calcium carbonate, CaCO3

1.75 mol CO₂

Explanation:

Step 1: Given data

Moles of calcium carbonate: 1.75 mol

Step 2: Write the balanced decomposition reaction

CaCO₃ ⇒ CaO + CO₂

Step 3: Calculate the moles of carbon dioxide produced from 1.75 moles of calcium carbonate

The molar ratio of CaCO₃ to CO₂ is 1:1. The moles of CO₂ produced are:

1.75 mol CaCO₃ × (1mol CO₂/1 mol CaCO₃) = 1.75 mol CO₂

asking the goog might u get an answer

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
