You want to create a garden that is 9 km long, 8.35 hm wide, and 35 cm deep. Calculate the volume in m^3 of dirt that you will n

Vanyuwa [196]

Answer:

$V=2630250m^3$

Explanation:

Hello,

In this case, since we need the volume in cubic meters and the given dimensions are in different units, the first step is to compute all of them in m:

$L=9km*\frac{1000m}{1km}=9000m\\ \\W=8.35hm*\frac{100m}{1hm}=835m\\ \\H=35cm*\frac{1m}{100cm} =0.35m$

Thus, the volume is computed by:

$V=H*L*W\\\\V=9000m*835m*0.35m\\\\V=2630250m^3$

Best regards.

When urea dissolves in water, the beaker becomes cold. Which statement describes this process? A) The ΔHsolvation is endothemic

e-lub [12.9K]

The answer is; D

Solvation is the process by which the molecules of a solute interact with those of a solvent to form solvates. The interaction involves the formation of temporary bonds between the molecules of the elements. These bonds in this rection absorb energy from the atmosphere hence the reaction feels cold to the touch. This is called an endothermic reaction.
