Given:

magnesium = 0.941 gram piece

Magnesium oxide= 1.560 grams

Formula:

(magnesium / magnesium oxide) x 100 = % Mg

100% - % Mg = percent composition of each element

Solution:

(0.941g Mg) / (1.560g MgO)

= 0.603

= 60.3% Mg

100% - 60.3%

= 39.7%

39.7% is the percentage composition of each element.

List the number of each type of atom on the left side of the equation C5H12(g)+8O2(g)→5CO2(g)+6H2O(g) C 5 H 12 ( g ) + 8 O 2 ( g
Gala2k [10]

Answer:

Carbon=5, hydrogen=12, oxygen=16

Explanation:

Carbon=5, hydrogen=12, oxygen=16

In order to effectively count the number of atoms, we look at the equation closely and take note of the stoichiometric coefficients of each reactant as this influences the number of atoms of that element present.

For instance, oxygen is diatomic and has a stoichiometric coefficient of 8. This implies the there are sixteen atoms of oxygen altogether.

Note that the left hand side refers to the reactants side.

What is the amount of heat released when 25g of water cools 12.5 degrees C ?
Over [174]
Water can't cool at a single temperature. It must start at a higher temperature, and drop to a lower temperature in order to cool. Unless we know the other temperature, there is no way to calculate the amount of thermal energy released.
