Answer:
Single displacement and reduction
Explanation:
In a single-displacement reaction, one element exchanges partners with another.
This is a single-displacement reaction, because the element Ca exchanges partners with H.
This is also a reduction/oxidation (redox) reaction, because the optically active of Ca increases from 0 to +2 (oxidation), while the oxidation number of H decreases from +1 to 0 (reduction),
The most common types of reactions are:
- Combination
- Decomposition
- Single displacement
- Double displacement
- Reduction/oxidation

Answer: Option C) Rinse the affected area with cool water for 10-15 minutes.
Explanation:
Once exposed to burns, whether chemical or heat, rinse the affected area of the body with cool water, as water is known to dissolve all burning particles attached to the skin, and cool off the blood vessels lying beneath the burned surface.
Unlike other options provided, rinsing affected area with cool water is the best first aid for skin burns
Barometer, it is used to measure air pressure
A melting point of a substance is a point at which the sample or substance start converting in liquid. For most substances, melting and freezing points are approximately equal. For example, the melting point and freezing point of mercury is 234.32 kelvins (−38.83 °C or −37.89 °F). Hope this helped!! :)
