How many protons are in am element
To convert from grams to moles, you must divide the given mass by the molecular weight. If this is so, then:
Water ≈ 18.02 grams/mol.
85.0 g/ 18.02 g/mol ≈ 4.72 moles
Answer:
As water vapor rises, there is an increase in the gravitational potential energy of the system. Part of this potential energy is released as snow falls onto the mountain. If an avalanche occurs, the snow on the mountain accelerates down slope, converting more <u>gravitational potential energy to kinetic energy.</u>
Explanation:
Answer:
This is required answer.
Explanation:
Given that,
Thermal energy chemical change lab report
We know that,
Thermal energy :
When we rise a temperature of any substance then the molecules of substance moves fastly then the heat produced. It is called thermal energy.
Chemical change in the thermal energy :
When we heat a substance then the thermal energy increases and the molecules of substance moves fastly. That means the chemical bonds are break in reactants due to energy.
In products, The new chemical bonds are create due to energy.
For example ; The coal is burned then produced heats water and change it into steam.
Hence, This is required answer.
As far as I know, may be wrong :When pressure is multiplied by a number, the gas volume also gets multiplied by the same number. So, the answer can be found by doing: (3.4/1.97)(12), and the answer is about 20.71.
