<span>164.0 First we must look up the atomic weight of all elements in calcium nitrate Ca: 40.078 N: 14.0067 O: 15.999 Then we compute the mass of the nitrate polyatomic ion which contains one nitrogen and 3 oxygen atoms. 14.0067+3*15.999 = 62.0037 For the entire molecule we calculate the weight of two nitrates and one calcium 2 * 62.0037 + 40.078 = 164.0152 rounding to the tenths place results in 164.0</span>

Which best describes thermal energy? It is the difference between internal energies of two or more substances. It is the sum of
Klio2033 [76]

Answer:

It is the portion of internal energy that can be transferred from one substance to another.

Explanation:

Thermal energy is the energy obtained by an object due to the motion of its particles.

It is also known as internal energy as it is the energy within the particles due to their motion.

Therefore, we can conclude that it is the portion of internal energy that can be transferred from one substance to another.

Hope this helps!

How is the strength of an acid affected by the number of hydrogen ions it contains​
adell [148]

More the no. of hydrogen ions more is the solution acidic.

pH means the power of hydrogen that determines the concentration of hydrogen ions or the level of acidiy or basicity of a solution.

so more the hydrogen ions more will be the Power of Hydrogen (pH) and thus more wil be the acidity.

What are the gas laws? (Include Boyle's law, charles's law, gay lussac's law, an avogadro's law) Could someone please summarize
Rina8888 [55]

Answer:

Boyle's Law: When the pressure of a gas increases, the volume of the gas will decrease as long as the temperature and amount of gas are constant.

So basically pressure is inversely proportional to Volume, when one increases, the other decreases, vice versa.

Equation: P_{1} V_{1} = P_{2} V_{2}

Charles Law: When the temperature of a gas increases, the volume of a gas will also increase if the pressure and amount of gas are constant.

So basically Temperature and volume are directly proportional.

Equation: \frac{V_{1}}{T_{1}} = \frac{V_{2} }{T_{2} }

Gay Lussac's Law: When the temperature of a gas increases, the pressure of a gas also increases when volume and the amount of gas remain constant.

Basically, Temperature and Pressure are directly proportional.

Equation: \frac{P_{1}}{T_{1}} = \frac{P_{2} }{T_{2} }

Avogadro's Law: The most intuitive gas law. When you increase the amount of gas, the volume will also increase.

Meaning the moles (amount of gas) is directly proportional to volume.

Equation: \frac{V_{1} }{n_{1} } = \frac{V_{2} }{n_{2} } (n stands for moles)

There is a combined gas law and ideal gas law but those are just the gas laws mentioned above but combined together. These should be everything.
