Answer:
because moles is the chemical unit*Avogadro's number, meaning it's the amount of atoms in the given unit.
Explanation:
Answer:
Harmony is correct, because Mendeleev’s model made predictions that came true.
Explanation:
Mendeleev published periodic table.
Mendeleev also arranged the elements known at the time in order of relative atomic mass, but he did some other things that made his table much more successful.
Our answer is : Harmony is correct, because Mendeleev’s model made predictions that came true.
it would be 26 because once you divide 160g by 5.0g and add 12.5 you would get 26
hope this helps
Answer:
science literacy among people has contributed a lot to the growth and progress of our economy considering the state of our society these days. People who have knowledge in science literacy indeed has contributed a lot of things for the betterment of society. Even though we have an unstable society, these “knowledge” has made its way to the top. In fact, it has contributed a lot of change for the economy. People who have the heart in science literacy must also have the heart in helping others so that their knowledge would also benefit those who are in dire need of support and help. Everything and anything these days are answerable by science and I think it would be great and easy to practice more of it.
Explanation:
The molar mass of methanol is 12.01 + 4.04 + 16 = 32.05 g/mol
230.0 g of methanol / 32.05 g/mol = 7.176 mol methanol
The heat of combustion of methanol (CH3OH or CH4O) is -715.0 kJ/mol. (Negative sign means the energy is released)
Multiplying 7.176 mol by -715.0 kJ/mol gives -5,131 kJ.
