Endothermic reactions<span>. An </span>endothermic reaction occurs <span>when the energy used to break the bonds in the reactants is greater than the energy given out when bonds are formed in the products. This means that overall the </span>reaction<span> takes in energy, therefore there is a temperature decrease in the surroundings.</span>
Answer:
pauli exclusion principle states that no two electrons in the same orbital can have the same spin.

Answer:
Any conductor (thing that electricity can go through) is made of atoms. Each atom has electrons in it. If you put new electrons in a conductor, they will join atoms, and each atom will deliver an electron to the next atom. This next atom takes in the electron and sends out another one on the other side.

Answer:
Explanation:
According to the Dalton's law of partial pressure, the total pressure of the gaseous mixture is equal to the sum of the pressure of the individual gases.
Partial pressure of carbon dioxide = 401 mmHg
Partial pressure of hydrogen gas = 224 mmHg
Total pressure,P = sum of the partial pressure of the gases = 401 + 224 mmHg = 625 mmHg
Also, the partial pressure of the gas is equal to the product of the mole fraction and total pressure.
So,
Similarly,
