Answer:

source Mass extinctions are episodes in which a large number of plant and animal species become extinct within a relatively short period of geologic time—from possibly a few thousand to a few million years. ... Permian Period — 252 million years ago. Devonian Period — 359 million years ago. Ordovician Period — 443 million years

BP: Nowadays, scientists are aware of five mass extinction events in the past, starting with the End-Ordovician Extinction 450 million years ago and up to the End-Cretaceous Extinction that killed off the dinosaurs 66 million years ago

<u>In your own words- Mass extinctions area unit episodes during which an oversized variety of plant and animal species become extinct at intervals a comparatively short amount of earth science time—from probably some thousand to some million years. ... Permian period — 252 million years past. period — 359 million years past. geological period — 443 million years</u>

<u>BP: today, scientists area unit alert to 5 mass extinction events within the past, beginning with the End-Ordovician Extinction 450 million years past and up to the End-Cretaceous Extinction that killed off the dinosaurs sixty six million years past </u>

bulgar [2K]

Answer: Mass of CO_2  produced in this reaction was 6.56 grams

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

CaCO_3(s)+2HCl(aq)\rightarrow H_2O(l)+CO_2(g)+CaCl_2(aq)

Mass or reactants =  Mass of CaCO_3+ mass of HCl = 16.00 + 64.80 = 80.80 g

Mass of products  = mass of aqueous solution + mass of CO_2 + = 74.24 + x g

Mass or reactants = Mass of products

80.80 g = 74.24 + x g

x = 6.56 g

Thus mass of CO_2  produced in this reaction was 6.56 grams
