Explanation:

A water fall falls and hits the base with force depending on the distance from which it fell.This force is caused by gravity pulling the water molecule as well as some other particles like eroded soil rapidly downwards.

What is the value of q when the solution contains 2.00×10−2 m sr2+ and 1.50×10−3m cro42−?

Law Incorporation [45]

Answer is: ion product for strontium chromate is 3·10⁻⁵.<span>
Balanced chemical reaction (dissociation) of strontium chromate:
</span>Sr²⁺(aq) + CrO₄²⁻(aq) → SrCrO₄.<span>
Qsp(</span>SrCrO₄) = c(Sr²⁺)·(CrO₄²⁻).<span>
c(</span>Sr²⁺) = 2.00·10⁻² M.
c(CrO₄²⁻) = 1.50·10⁻³ M.
Q = 2.00·10⁻² M · 1.50·10⁻³ M.
Q = 0.00003 = 3·10⁻⁵ M².

You are in space and running out of water. You do have a great deal of magnesium carbonate pentahydrate. It is possible to extra

lana [24]

Answer:

51.65%

Explanation:

Magnesium carbonate pentahydrate is $MgCO_3.5H_2O$

1 mole of the compound contains 5 moles of water. The water can be extracted by heating the the compound and allowing the water to condense.

$MgCO_3.5H_2O --> MgCO_3 + 5H_2O$

1 mole of the compound contains 5 moles of water molecule

mole = mass/molar mass

1 mole of the compound weighs: 1 x 174.3903 = 174.3903 g

5 moles of water weighs: 5 x 18.01528 = 90.0764 g

Percentage by mass of hydrate in magnesium carbonate pentahydrate

= 90.0764/174.3903 x 100%

= 51.65%

What would happen if the energy from the sun was not reflected back

Savatey [412]

<h2>It would have an effect very much like over inflating a balloon. The space inside the Dyson Sphere would be overfilled with energy and the Sphere would be assaulted by energy that exceeds it's capacity to reflect it.</h2>
