The Curiosity rover found sulfur compounds in rocks and carbon in organic compounds like propane, butene, benzene, toluene and thiophene.
It detected methane, not in soil samples, but in the Martian atmosphere.
It did not discover helium in underground pockets. The hole it can drill is only 5 cm deep.
Answer: C4H
Explanation:
An hydrocarbon is a compound with carbon and hydrogen atoms only covalently linked together.
Thus, all hydrocarbons have a basic formula of CH.
Now, mass of hydrocarbon = 100%
Mass of hydrogen = 20%
Mass of carbon = (100% - 20%) = 80%
i.e Carbon : Hydrogen
= 80% : 20%
= (80% / 20%)
= 4 : 1
Thus, the empirical formula of the hydrocarbon is C4H

Isotopes are the atoms of the same element with same atomic number but different mass number isotopes of same element have same chemical properties due to same number of electrons atomic number of an atom is the number of electrons protons in it and mass number is the sum of protons
Hydrogen reacts with water according to the following equation:
2H2 + O2 ..............> 2H2O
From the periodic table:
molar mass of hydrogen = 1 gram
molar mass of oxygen = 16 grams
Therefore:
4 grams of hydrogen react with 32 grams of oxygen to produce 36 grams of water vapor.
Now, we need to determine the limiting reactant in the equation. By comparing, we can deduce that hydrogen is the limiting reactant (<span>because half of that amount is less than how much O2 you have).
This means that, once the amount of the reacting hydrogen is consumed, the reaction will stop. So, our calculations will be based on the amount of reacting hydrogen.
Now, back to our calculations:
we know that 4 grams of hydrogen are needed to produce 36 grams of water vapor.
To know how many grams of water vapor were produced from 1.8 grams of hydrogen, we will use cross multiplication as follows:
mass of water vapor = (1.8 x 36) / 4 = 16.2 grams</span>
