The equation below is for potassium oxide.
ValentinkaMS [17]

Answer: The ratio of atoms of potassium to ratio of atoms of oxygen is 4:2

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed, and remains conserved. The mass of products must be same as that of the reactants.

Thus the number of atoms of each element must be same on both sides of the equation so as to keep the mass same and thus balanced chemical equations are written.

K exists as atoms and oxygen exist as molecule which consists of 2 atoms. The ratio of number of atoms on both sides of the reaction are same and thus the ratio of atoms of potassium to ratio of atoms of oxygen is 4:2.

During heavy rain, a section of a mountainside measuring 2.3 km horizontally (perpendicular to the slope), 0.75 km up along the
Jobisdone [24]

Answer:

93328 kg

Explanation:

\rho = Density of mud = 1900 kg/m³

Volume of the cuboid is given by

V=2300\times 750\times 1.4\\\Rightarrow V=2415000\ m^3

Volume is also given by

V=Al\\\Rightarrow l=\dfrac{V}{A}\\\Rightarrow l=\dfrac{2415000}{520\times 520}\\\Rightarrow l=8.9312\ m

The length of the cuboid is 0.89312 m

For the small volume

V_a=al\\\Rightarrow V_a=5.5\times 8.9312\\\Rightarrow V_a=49.12\ m^3

Mass is given by

m=\rho V_a\\\Rightarrow m=1900\times 49.12\\\Rightarrow m=93328\ kg

The mass of the mud is 93328 kg
