Answer:
Atoms, Different, compounds, atoms
Explanation:
Answer:
So first formula of uniform acceleration is= a=(v-u)/t
Now use this formula and find the answer
Explanation:
The safest conclusion would be that the marine organisms dominated the living world at that time. It is really hard to say with certainty that there were no land organisms just from the lack of their fossils in that era. The process of forming the fossils is quite fragile and requires various conditions to be fulfilled ( perfect temperature, moisture, the composition of the ground etc.), so a lack of fossils can also be due the bad conditions for fossilization at that time, not the lack of organisms present.
With the<u> balanced reaction</u> we're able to use the<em> stoichiometric ratios </em>in order to solve each of the questions:
2C₁₂H₄Cl₆ + 23O₂ + 2H₂O → 24CO₂ + 12HCl
a) 10.0 mol O₂ * = 0.870 mol H₂O
b) When we work with mass, we use the <em>molecular weight</em>:
15.2 mol H₂O * 3324.24 g HCl
c) 76.5 g HCl * 50.37 mol CO₂
d) 100.25 g CO₂ * =68.48 g C₁₂H₄Cl₆
e) 2.5 kg C₁₂H₄Cl₆ = 2500 g C₁₂H₄Cl₆
2500 g C₁₂H₄Cl₆ * 1515.80 g HCl
