Answer:
0 g.
Explanation:
Hello,
In this case, since the reaction between methane and oxygen is:

If 0.963 g of methane react with 7.5 g of oxygen the first step is to identify the limiting reactant for which we compute the available moles of methane and the moles of methane consumed by the 7.5 g of oxygen:

Thus, since oxygen theoretically consumes more methane than the available, we conclude the methane is the limiting reactant, for which it will be completely consumed, therefore, no remaining methane will be left over.

Regards.
Answer:
For example, the sugar found in milk is called lactose. With the aid of the enzyme, lactase, the substrate, lactose, is broken down into two products, glucose and galactose. People who don't make enough lactase have trouble digesting milk products and are lactose intolerant.
Answer:
Covalent bond
Explanation:
they will make a covalent bond with each other because both are non- metals and have a low electronegativity difference.
Proteins make up many many important structures in our cells ( ex : receptors , Enzymes , integral proteins and so on )
HCl is an acid
C5H5N is a base
Cl- is a base
HC5H5N+ is an acid
