5A. The volume of the rectangular object is 10 x 5 x 20 = 1000 cubic centimeters.
5B. The density of the object is 800 grams / 1000 cubic centimeters = 0.8 g/cm3.
5C. The object will sink in water because its density is greater than the density of water, which is 1 g/cm3.
Buoyancy is the upward force exerted on an object immersed in a fluid (liquid or gas), which opposes the object's weight. This force is caused by the difference in pressure between the top and bottom of the object.
Density is a measure of how much mass is contained in a given volume of a substance. It is typically expressed in units of kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). The density of an object can determine whether it floats or sinks in a fluid, with objects that are less dense than the fluid rising to the surface and those that are more dense sinking to the bottom.

Answer:
Explanation:
The chemical formula for hydrogen is H while chemical formula for oxygen is O
Considering that two moles of hydrogen and 2 moles of oxygen react to form water, the equation will be
The number of oxygen molecules don't balance on both LHS and RHS hence to balance it, we put it as follows
Normally, two moles of hydrogen require only one mole of oxygen to form two moles of water.
