Hello!! My answer would be that they should add the solar panels that faces the south. Since the sun rises in the east and sets in the west, the south portion would get both sunlight from the east and west sides. I hope this helps!!

Answer:

Magnesium

  Zinc

 Iron

Copper

Explanation:

The given elements are:

 Magnesium, copper, iron and zinc

 We are to put them in the order from the least reactive to the most reactive of all.

To solve this problem, we simply use the activity series of metals to arrange the elements.

The activity series arranges metals from the most reactive to the least reactive. The more reactive metals displaces the lesser one from solutions.

  So;

      Magnesium

       Zinc

       Iron

       Copper

Copper (II) Sulfate pentahydrate, CuSO4 X 5H20 is heated in an open crucible to remove the water. (a) Diagram the lab set up cle
balu736 [363]

The water molecules are not completely removed so additional heating is required.

Explanation:

We have the copper (II) sulfate pentehydrate with the chemical formula CuSO₄ · 5H₂O.

molar mass of CuSO₄ · 5H₂O = 159.6 + 5 × 18 = 249.6 g/mole

Knowing this, we devise the following reasoning:

if in       249.6 g of CuSO₄ · 5H₂O there are 90 g of H₂O

then in         8 g of CuSO₄ · 5H₂O there are Y g of H₂O

Y = (8 × 90) / 249.6 = 2.88 g of water

mass of dried CuSO₄ = mass of CuSO₄ · 5H₂O -  mass of H₂O

mass of dried CuSO₄ = 8 - 2.88 = 5.12 g

5.12 g is less that the weighted mass of 6.50 g. We deduce from this that the sample needs additional heating in order to remove all the water (H₂O) molecules.

What effect does an increase in products have on the reaction rate of a mixture at equilibrium? A. The forward reaction rate inc
Anna007 [38]

<u>Answer:</u>

<em>D. The reverse reaction rate increases.</em>

<u>Explanation:</u>

The<em> rate of reverse</em> increases if the products are increased in a mixture at equilibrium.

At first,<em> rate of forward and backward</em> reactions are same for a <em>mixture in equilibrium. </em>

<em>If we add products or,the reaction moves to the opposite side I.e towards reactants side.</em>

so,according to the Le Chateliers principle,the reaction shifts opposite to the side of increase. so,according to the Le Chateliers priciple, <em>the rate of reverse or backward reaction will increase with the increase in the products.</em>
