Amount of CH4 is excess, so no need to worry about it
<span>but the limiting factor is the Oxygen </span>
<span>according to stranded equation, </span>
<span>CH4 + 2 O2 --> CO2 + 2 H2O ΔH = -889 kJ/mol </span>
<span>just by taking proportions </span>
<span>(-889 kJ/mol) / 2 x 0.8 mol = - 355.6 kJ </span>
<span>so i think the answer is (a)</span>
The nuclear fusion<span> in our </span>sun<span> combines two </span>hydrogen atoms<span> (the smallest and lightest </span>atoms<span>) together to </span>form<span> one </span>helium atom<span> (a slightly larger </span>atom). <span>During the process some of the </span>mass<span> is converted into energy.</span>
The reactants of the reaction of single replacement that produces ZnCl₂ and H₂ is Zn + 2HCl
Explanation
In a single replacement reaction is a chemical reaction whereby an element react with compound and take the place of another element in that compound.
zn displaces H from HCl to form ZnCl₂ and H₂ according to below equation.
Zn +2HCl → ZnCl₂ + H₂
Answer:
There are 36 grams in 3.00 moles of carbon.
HOW TO CALCULATE MASS:
The mass of a substance can be calculated by multiplying the number of moles by its molar mass. That is;
mass (g) = no. of moles (mol) × molar mass (g/mol)
According to this question, 3 moles of carbon was given. The mass can be calculated as follows:
atomic mass of Carbon = 12g/mol
Mass = 12g/mol × 3mol
Mass = 36g.
Therefore, there are 36 grams in 3.00 moles of carbon.
