Answer:
The heat capacity of the calorimeter or of the reaction mixture may be used to calculate the amount of heat released/absorbed by the chemical reaction. The amount of heat released or absorbed per gram or more of the reactant can then be calculated from the mass of the reactants.

Partial pressure is the pressure that is exerted by individual gases.
Partial pressure is calculated as the product of total pressure by the mole fraction of the corresponding gas.
pressures exerted by gases are in three different units, therefore we can convert them all into a common unit - torr
1 - 0.845 atm - 0.854 atm x 760 Torr/atm = 642 torr
2 - 120 torr
3 - 210 mmHg - 1 mmhg is almost equivalent to 1 torr - therefore its 210 torr
total pressure - 642 + 120 + 210 = 972 torr
answer is 972 torr
The available energy decreases as one moves upward in an energy pyramid.
<h3>Energy pyramid</h3>
The energy pyramid represents a model of how energy is transferred from one trophic level to another in ecosystems.
Energy is transferred from producers to primary consumers, from primary to secondary consumers, from secondary to tertiary consumers, and so on.
Only about 10% of the available energy in one trophic level is transferred to the next with the remaining 90% being lost as heat to the environment.
Thus, as one moves up the energy pyramid, the available energy decreases. This is why organisms at the higher end of the energy pyramid have to devise an efficient way of extracting energy from their foods.

Answer:
Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
