Answer:
I cant really explain what you cant use but you use cubic centimeters, cubic meters, or liters.
Explanation:
Remember the volume is how much space something takes up, and the only way to identify the volume is by using something you can convert into something else, like centimeters into cubic meters (100 cm³ is equal to 1 m³), and liters (same thing, but in liquid form.)
Answer:
When hydrogen is subjected to large enough pressure, it solidifies according to theory.
Explanation:
According to theory, when hydrogen molecules are subjected to enormous degree of pressure the molecules will solidify.
What happens here is that the hydrogen–hydrogen bonds in the hydrogen molecule will break apart and the molecules collapses into hydrogen atoms.
Hence, when hydrogen is subjected to large enough pressure, it solidifies according to theory.
Because when the cells divide (resulting in more cells) the multicellular organism mantains its strong cells and when one cell is damaged the other cells compensate for that damaged cell.
Answer:
0.86 moles H₂O
Explanation:
To solve this problem, it is important to first determine the balanced chemical equation. The balanced equation is necessary as it will provide the mole-to-mole ratio needed to convert between moles O₂ and moles H₂O.
The unbalanced equation:
C₈H₁₈ (l) + O₂ (g) ---> CO₂ (g) + H₂O (g)
<u>Reactants:</u> 8 carbon, 18 hydrogen, 2 oxygen
<u>Products:</u> 1 carbon, 2 hydrogen, 3 oxygen
As you can see, the equation is not balanced because there are unequal amounts of each element on both sides. Balancing the equation is a matter of guessing-and-checking to see which combination of coefficients work.
The balanced equation:
2 C₈H₁₈ (l) + 25 O₂ (g) ---> 16 CO₂ (g) + 18 H₂O (g)
<u>Reactants:</u> 16 carbon, 36 hydrogen, 50 oxygen
<u>Products:</u> 16 carbon, 36 hydrogen, 50 oxygen
Now that the equation is balanced, we can use the coefficients of O₂ and H₂O to construct our mole-to-mole ratio and perform our conversion. The final answer should have 2 sig figs to match the given value (1.2 moles). The state of matter is most likely not necessary to include in your final answer.
1.2 moles O₂ 18 moles H₂O
--------------------- x ----------------------- = 0.86 moles H₂O
25 moles O₂
I haven't learned this yet but my friend did I'll text them and get back to you with the answer in a bit brb!
