The last one. A mixture isn’t chemically combined.
Answer:
<h2>
2 is the coefficient of CO₂</h2>
Explanation:
The <u>coefficient</u> is the number in front of a substance that indicates how many molecules or atoms are. For example, when we see 5He, it shows that there are 5 atoms of helium. When we see 5H₂O, it indicates that there are 5 molecules of water, each having 2 atoms of hydrogen and 1 atom of oxygen, so a total of 10 hydrogen atoms and 5 oxygen atoms.
Answer:
hi
Explanation:
A mixture which has uniform composition throughout its mass is called homogeneous mixture. The word "homo" means "same". For example, when you completely dissolve salt in the water, you form a homogeneous mixture.
Answer:
Hurricanes occur when ocean water warms during the spring, summer and early fall.
Explanation:
Warm air just above the water’s surface rises. The rising warm air creates a reduction in pressure at the surface, what meteorologists call a low-pressure area. Because nearby air is at a higher pressure, it will flow into the low-pressure zone.
