Chemistry

'with two kittens' describe the cat. So, you should write 'is sleeping'. But if you mean that all three of them are sleeping, write 'A cat and his two kittens are sleeping'.

The amount of heat energy required to solid substance solid into a liquid state without any changes in temperature

______________________

Apex: The amount of energy required to turn a mole of a solid into a liquid

Scale step reactions so products/reactants that don't appear in the target reaction will cancel out.

The amount of randomness in the system

F=v/&

An Arrhenius acid donates H+ ions. (apex).

ms= +1/2

Grams liquid × mol/g × Hfusion

The energy used to hold the nucleus together

5.98 x 10^14 Hz

SO2Cl2(g) --> SO2(g) + Cl2(g)

ap3x answer

ml=0

A range of wavelenghs of frequencies of electromagnetic raditation

The wavelength is 671 nm.

The potential energy of the reactants is greater than the potential energy of the products.

1kj x 1/H fusion x g/mol solid

4.5 × 1015 J

It expresses a complete idea.
