C, 0.746 mol Ag.
1 mol Ag = 6.022 x 1023 atoms of Ag -> 4.49 x 1023 atoms of Ag x 1mol Ag/6.022 x 1023 atoms -> 0.746 mol Ag
When warm air rises, cooler air will move in to replace it, so wind often moves from colder areas to warmer areas. The greater the difference between the high and low pressure or the shorter the distance between the high and low pressure areas, the faster the wind will blow
So the correct answer will be:
When a high and a low pressure air mass are far apart, air moves slowly from high to low pressure
The differences in the properties of diamond and graphite is as a result of how their particles are arranged in space. This space arrangement leads to distinct crystal structures for the two compounds. In diamond, the carbon atoms are arranged in tetrahedral shape while in graphite the carbon atoms arrayed in planes.
Answer:
NaHCO₃
Explanation:
NaHCO₃ is the chemical formula for sodium bicarbonate or baking soda. It has one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms.

Answer:
The answer to your question is:
atomic number (Z): 6
mass number (A) : 13
Explanation:
Carbon has an atomic number of 6 and a mass number of 12,
Mass number = # protons + # neutrons
12 = 6 + # neutrons
#neutrons = 12 - 6 = 6
For the carbon isotope the atomic number does not change is still 6
13 = 6 + # neutrons
# neutrons = 13 - 6
# neutrons = 7
