How many kilojoules of heat will be released when exactly 1 mole of manganese, mn, is burned to form mn3o4 at standard state condaition?

The amount of heat released is 462.3 kJ

Explanation:

The chemical equation for the reaction of manganese and oxygen to produce manganese (II,III) oxide follows:

We need to calculate the amount heat released for 1 mole of manganese.

To calculate the amount of heat released, we use unitary method:

When 3 moles of manganese is burnt, the amount of heat released is 1387 kJ

So, when 1 mole of manganese is burnt, the amount of heat released will be =

Hence, the amount of heat released is 462.3 kJ

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
