Answer:
<h2>4 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question we have
We have the final answer as
<h3>4 g/cm³</h3>
Hope this helps you
Total mass of CaCO3 = 40 amu of Ca + 12amu of C + 16×3 amu of oxygen = 100amu of CaCO3
i.e 100 tonnes of CaCO3 .
mass of CO2 = 12amu of C + 2× 16amu of O = 44 amu of CO2
mass % of CO2 in CaCO3 = (44/100)×100 =44%
i.e
44% of 100 tonnes is CO2.
=44 tonnes of CO2.
therefore, 44% of CO2 is present in CaCO3.
Answer:
I would say a cooled
Explanation:
because yeah it's going to be cold when it travels from Antarctica but then it's going on towards Africa and yeah the water is going to get warmth but it's going to cool the land of Antarctica because it's so dry and hot and humid but the water is going to be more warmed because Antarctica the water is freezing so you're trying to ask the temperature of the water it'd be more warm if you're trying to ask kind of like the temperature of the land it would be cooled
Answer:
Constraints are restrictions that need to be placed upon variables
Explanation:
Constraints are restrictions (limitations, boundaries) that need to be placed upon variables used in equations that model real-world situations. It is possible that certain solutions which make an equation true mathematically, may not make any sense in the context of a real-world word problem.
