Answer:
15.4 g
Explanation:
Let's consider the decomposition of calcium carbonate to form carbon dioxide.
CaCO₃ → CaO + CO₂
Step 1: Calculate the moles of carbon dioxide
Since the conditions are not explicit, we will suppose that CO₂ is at standard temperature and pressure (STP). In these conditions, <em>1 mole of any gas has a volume of 22.4 L</em> (assuming ideal behavior).
Step 2: Calculate the moles of calcium carbonate
<em>The molar ratio of CaCO₃ to CO₂ is 1:1.</em> Then, the moles of CaCO₃ required are 0.154 moles.
Step 3: Calculate the mass of calcium carbonate
<em>The molar mass of CaCO₃ is 100.09 g/mol.</em> Then,
Hey there
the answer is A. Atoms of the same element can have different number of neutrons
thank you gurl
Yes, you would have to bring an umbrella because if the island is named mystery you never know when it'll rain.
D. Hippocrates
As quoted from Wikipedia, "he is often referred to as the "Father of Medicine"[1] in recognition of his lasting contributions to the field as the founder of the Hippocratic School of Medicine."
I hope this helps!
Cheers, July.
Answer: similar: Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Different:Protons are a type of subatomic particle with a positive charge. And Neutrons are a type of subatomic particle with no charge (they're neutral).
