Which represents the empirical formula for x4y8?

Usually, in writing the empirical formula of a substance, the carbon atom is placed first followed by the hydrogen, oxygen and other atoms. If you are given X4Y8, the empirical formula is C4H8, possibly an alkane molecule having the formula CnH2n with n having the number of atoms.

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
