Answer:
6.05g
Explanation:
The reaction is given as;
Ethane + oxygen --> Carbon dioxide + water
2C2H6 + 7O2 --> 4CO2 + 6H2O
From the reaction above;
2 mol of ethane reacts with 7 mol of oxygen.
To proceed, we have to obtain the limiting reagent,
2,71g of ethane;
Number of moles = Mass / molar mass = 2.71 / 30 = 0.0903 mol
3.8g of oxygen;
Number of moles = Mass / molar mass = 3.8 / 16 = 0.2375 mol
If 0.0903 moles of ethane was used, it would require;
2 = 7
0.0903 = x
x = 0.31605 mol of oxygen needed
This means that oxygen is our limiting reagent.
From the reaction,
7 mol of oxygen yields 4 mol of carbon dioxide
0.2375 yields x?
7 = 4
0.2375 = x
x = 0.1357
Mass = Number of moles * Molar mass = 0.1357 * 44 = 6.05g
Answer: sexual reproduction results to the offspring having a mix of genetic characteristics of the parents. Where as Asexual offspring tend to look like their parent.
Explanation:
Intercourse leads to the mixing of genetic material. Asexual reproduction is often the parent making a separate copy of themselves.

![\boxed{\rm \text{[ClO$_{2}^{-}$] increases}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Crm%20%5Ctext%7B%5BClO%24_%7B2%7D%5E%7B-%7D%24%5D%20increases%7D%7D)
Explanation:
At the beginning, you have two reactions happening:
As you add KOH(aq), it does two things:
- It increases the volume of the solution.
- It reacts with the hydronium ions to form water.
A) The HCl is completely ionized. The Cl⁻ does not react, but it is diluted when the volume of the solution increases. [Cl⁻] decreases.
B) The KOH reacts with the H⁺ and removes it from the solution. [H⁺] decreases.
C) When all the H⁺ from the HCl has been neutralized, the KOH starts neutralizing the H⁺ from the HClO₂. According to Le Châtelier's Principle, more HClO₂ will dissociate to replace the decreased H⁺. [HClO₂] decreases.
D) As HClO₂ reacts, it forms ClO₂⁻. ![\boxed{\rm \textbf{[ClO$_{2}^{-}$] increases}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Crm%20%5Ctextbf%7B%5BClO%24_%7B2%7D%5E%7B-%7D%24%5D%20increases%7D%7D)
Hello There,
I believe you stated your question wrong. This is not possible. A tennis ball can't have more mass than a gold ball.
If you MEANT to say:
A golf ball has more mass than a tennis ball because
then your answer would be:
It contains more matter
Best Of Luck,

Answer:
Chemical equation for photosynthesis
A water + carbon dioxide + sunlight → oxygen + glucose. B carbon + oxygen → carbon dioxide. C hydrogen + oxygen → water.
Explanation: This same photosynthesis cycle is usually expressed as: 6CO2 + 6H2O + 6O2 + C6H12O6. This implies that the solute, six carbon dioxide molecules plus 6 hydroxyl groups, are translated into something like a sugar molecule or six oxygen molecules, the goods, exploiting light energy absorbed the chlorophyll (implied by arrow).
