B, THE PH OF ACID IS ALWAYS BETWEEN 0 AND 7, BUT REMEMBER THAT 7 IS NEUTRAL
Once heat from the sun penetrate the Earths atmosphere, the heat is circulated as warm air rises and cold air sinks,this process is called convection Convection can be demonstrated by placing a heat source {cooker} at the side of a glass full of a liquid, and observing the changes in temperature in the glass caused by the warmer fluid moving into cooler areas
Answer:
The most likely to occur when jagged edges of rock plates grind past each other is the presence of a high degree of frictional force.
This may cause the rocks to be broken down into smaller particles.
It also implies that the energy necessary for further disintegration and movement of rocks is stored up.
HCl = H⁺ + Cl⁻
c(HCl)=1.00*10⁻⁴ mol/l
[H⁺]=c(HCl)=1.00*10⁻⁴ mol/l
pH=-lg[H⁺]
pH=-lg(1.00*10⁻⁴)=4
pH=4
Answer:
<h2>Vector quantity</h2>
Explanation:
Momentum is a vector quantity because it has both magnitude and direction
