The silicon uses in :
1- Micro-chips.
2- Motherboards
3- components on nano-technologies
4- tablet
5- Phones
The explanation:
- When the silicon incorporated into electronics, They are termed as silicon wafers. It is used as a semiconductor.
- And when it combined with the other conductors this process called doping and become ideal to make transistors and be able to amplify electric signals.
That's how Silicon shape our technological reality.
B.) Areas at low latitudes have the warmest water because they receive the most direct sunlight.
C.) Areas at high latitudes have the warmest water because they have the longest seasons.
D.) Areas at high latitudes have the warmest water because their days are the longest.
Areas at low latitudes have the warmest water because they have the least change in temperature throughout the year. Therefore, option A is correct about the relationship between a geographical area and surface water temperature.
Ocean temperatures typically range from -2o to 30o C. (28-86o F). Surface water in low latitude regions tends to be the warmest, whereas surface water at the poles is obviously much colder It is worth noting that water on the eastern side of the ocean basins is colder than water on the western side at equivalent latitudes.
Despite the fact that surface water can be quite warm, the majority of the water in the oceans is deeper, colder water, so the average temperature of the entire ocean is around 4° C, which is roughly the temperature inside your refrigerator.
Therefore, the lower altitudes is having warmest water than that at higher altitudes.

Answer:
B
Explanation:
Low Latitudes get the most sunlight, sunlight causes the water to warm up.
Answer:
2moles of H2
Explanation:
First, let us generate a balanced equation for the reaction between calcium and water. This is illustrated below:
Ca + 2H20 —> Ca(OH)2 + H2
From the equation,
2moles of H2O produced 1mole of H2.
Therefore 4moles of H2O will produce = 4/2 = 2moles of H2.
