When calcium oxide reacts with water, then it combines with water and forms calcium hydroxide.
CaO + H2O → Ca(OH)2
Calcium oxide + Water → Calcium hydroxide
Basic oxides are oxides that show basic properties in opposition to acidic oxides and that either react with water to form a base

Answer:
R₂ = V₂R₁/(E + V₂)
Explanation:
By voltage divider, V₂ = ER₂/(R₁ + R₂)
So, cross-multiplying, we have
V₂(R₁ + R₂) = ER₂
expanding the bracket, we have
V₂R₁ + V₂R₂ = ER₂
collecting like terms, we have
V₂R₁ = ER₂ + V₂R₂
factorizing, we have
V₂R₁ = (E + V₂)R₂
dividing through by (E + V₂), we have
R₂ = V₂R₁/(E + V₂)
a. By the work-energy theorem, the total work required to stop the car is equal to the change in its kinetic energy,
<em>W</em> = 0 - 1/2 (750 kg) (25 m/s)² ≈ -230 kJ
b. The car covers a distance <em>x</em> as it stops such that
<em>W</em> = (-725 N) <em>x</em> ==> <em>x</em> ≈ 320 m
Answer:
C. both
Explanation:
kinetic energy bcs it's moving and gravitational potential energy for it's descend.
