To move? I think that's right
Answer:
1.02x10^24 atoms
Explanation:
The coefficients (the numbers before each susbtance) in this equation tell us that for every 2 moles of hydrogen used, there will be 1 mole of tin produced. This is a fixed ratio, which means if we use 4 moles of H2, 2 moles of tin will be produced.
One mole contains Avogadro's number of atoms (6.02 x 10^23). So two moles would contain twice as many atoms as this.
2 x 6.02x10^23 = 1.02x10^24 atoms.

D- the uneven heating causes global wind patterns
Answer:
B
Explanation:
Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. ... In this case, the products, or final state, have more free energy than the reactants, or initial state. Endergonic reactions are non-spontaneous, meaning that energy must be added before they can proceed.
Answer:
Conduction is heat transfer through the direct contact of two subjects. The best example of this would be C, because it is the direct transfer of heat from the lightbulb to your hand. :)
