The statement which best explains the change that must happen at the molecular level is below:
Explanation:
The molecules move more slowly and their average kinetic energy decreases
Compound X is an isomer of butane with different chain types. It is either straight chain or bend chain.
Answer:
0.1159 M
Explanation:
Using the formula below:
CaVa = CbVb
Where;
Ca = concentration/molarity of acid (M)
Cb = concentration/molarity of base (M)
Va = Volume of acid (mL)
Vb = volume of base (mL)
According to this question, the following information were given:
Ca = ?
Cb = 0.2831 M
Va = 26.86 mL
Vb = 11.00 mL
Using CaVa = CbVb
Ca × 26.86 = 0.2831 × 11
26.86Ca = 3.1141
Ca = 3.1141 ÷ 26.86
Ca = 0.1159
The molarity of the acid (H2SO4) solution is 0.1159 M
Answer:
The release of energy from fuels is used to make other forms of
energy. When gasoline burns in a car engine, some of the
chemical energy in the gasoline is converted into heat. The heat
is converted into mechanical energy. The mechanical energy
moves the car .

Answer:
Mass is Universal and weight is tied to the strength of the gravitational force of the planet .
Explanation:
The reason is because without mass you have no weight witch means if you have a certain amount of mass you will have a certain weight .
