The answer is B I had took that last year
Answer:
9√3
Explanation:
Given that :
UV = 18
Angle V = 60°
To obtain the measure of UW = v
Using trigonometry :
Sinθ = opposite / hypotenus
Sinθ = UW / 18
θ = 60°
sin60° = UW / 18
Sin 60° = √3/2
√3 /2 = UW / 18
UW = 18 * √3/2
UW = 9 * √3
UW = 9√3
For neutralization of acid by a base (or vice versa), the equation should be used.
M₁V₁ = M₂V₂
where M's are the molarity and the Vs are the volume. Substituting the known values,
(0.150M)(25) = M₂(15 mL)
The value of M₂ from the equation is equal to 0.25M. Thus, the concentration of the acid is 0.25M.
The continuous cycling of carbon in the earyh is known as the carbon cycle.
<h3>What is the carbon cycle?</h3>
The carbon cycle is a cycle which explains the various processes by which carbon is recycled between the atmosphere and the earth.
The constant flow of carbon on earth through organisms and the air is known as the carbon cycle. Plants absorb carbon from the atmosphere in the form of carbon dioxide. They use it for respiration and food production.
Animals consume plants, transferring carbon along the food chain.
Plants and animals respire and release carbon into air. When the animals and plants die, they are eaten by decomposers.
Carbon enters back into the atmosphere in the form of carbondio dioxide.
Therefore, the continuous cycling of carbon in the earth is known as the carbon cycle.

Answer:
False.
This is false because, no chemical reaction could possibly happen.
But in case of sodium it is highly reactive with water.......... so there will be a chemical reaction.
but as sodium is not a insoluble molecular compound this is not applicable to the situation.
