Answer:
The percentage of volume of ethanol is 35%.
<u>Explanation:</u>
The percentage of volume of ethanol is calculated by
Percent of volume of ethanol = (volume of X / total volume) * 100
We are going to assume these volumes will be added together to make 100mL.
Percent volume of Ethanol = (volume of ethanol / total volume) * 100
= 35mL / 100mL * 100
= 35%
Answer:
The used term is nonmetal.
Explanation:
Nonmetals are elements that are not shiny or are not <u>good conductors of electricity or heat. </u>
The periodic table has <u>approximately 23 nonmetals in it. </u>
In the periodic table, we can find elements. These ones could be <u>nonmetal and metals. </u>
The elements that lack metallic properties are the nonmetals.
Metals are <u>good conductors of heat and electricity, like Cu or Fe.</u>
Although, <u>nonmetals are not good conductors. </u>
Answer:
The rate of formation of CO₂ is 11,7 M/s
Explanation:
The rate in a chemical reaction is defined as the change in concentration over the change in time
For the reaction:
2C₆H₁₄(l) + 19O₂(g) → 12CO₂(g) + 14H₂O(g)
The rate of dissapearance of C₆H₁₄ is 1,95 M/s
As 2 moles of C₆H₁₄ produce 12 moles of CO₂, the rate of formation of CO₂ will be 12/2 times faster than rate of disappearance, thus, rate of formation of CO₂ is:
1,95 M/s C₆H₁₄× = <em>11,7 M/s</em>
