The balanced chemical equation for the <span>combustion of ethane is
2C</span>₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(l)
The stoichiometric ratio between C₂H₆(g) and CO₂(g) is 1 : 2
Hence,
moles of CO₂(g) produced = moles of reacted C₂H₆(g) x 2
= 1.00 mol x 2
= 2.00 mol
Hence, the correct answer is "C".
Answer:
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.
Explanation:
Answer:
First, they involve radially aligned ridges and valleys outside the nest site. Second, the male decorates these ridges with fragments of shells. Third, the male gathers fine sediments to give the resulting formation a distinctive look and coloring.

We know that the particles in a matter have energy. They have kinetic energy, potential energy, chemical energy, electrical energy etc.
When we give heat to a matter it gains energy and there is an increase in its internal energy. Or we can say that particles in a matter have more energy at higher temperature than particles in a matter at low temperature
As ice is formed below zero degree celsius so the particles in ice must have lesser energy than water at higher temperature.
Thus true statement will be
The particles in boiling water have more energy than the particles in ice water do.
Answer:
Explanation:
Hello!
In this case, since the reaction between hydrogen and oxygen to produce water is:
When equal masses of each reactant go in contact to carry out the reaction, we can identify the maximum mass of yielded water as the fewest mass yielded by each reactant, just as shown below:
Thus, since hydrogen yields more water than real, we limit the maximum mass of water to those 55.2 g yielded by oxygen as hydrogen would be in excess.
Best regards!
