Answer:

B) k_{sp} =[Mg_{aq} ]*[OH_{aq}]^{2}

Explanation:

Ksp is the solubility product constant.

For a generic chemical equation

AB_{2} = A_{aq}+2B_{aq}

The Ksp for this generic chemical equation is

k_{sp} =[A_{aq} ]*[B_{aq}]^{2}

So the Ksp fot the Mg(OH)2 is

k_{sp} =[Mg_{aq} ]*[OH_{aq}]^{2}

In an attempt to maximize the yield of methanol (amount of methanol produced), a chemist would try to shift the equilibrium as f
MakcuM [25]

Answer:

removing the methanol as it is formed

Explanation:

One of the ways to drive the equilibrium position towards the right is to remove one of the products formed.

According to Me Chatelier's principle, the imposition of a constraint on a system in a equilibrium causes the equilibrium position to shift towards a new position that annuls the constraint. Hence, removing the methanol causes the equilibrium position to shift to the far right in order to reestablish equilibrium according to Le Chatelier's principle.

which two quantities are used to predict gravitational force according to Newton's law of universal gravitation a. mass and spee
NISA [10]

Answer:

(b). Mass and distance.

Explanation:

The gravitational force between two objects is given by Newton's law of universal gravitation. The formula is as follows :

F=G\dfrac{m_1m_2}{r^2}

Here,

G is universal gravitational constant

r is the distance between two objects

It is very clear that the gravitational force is directly proportional to the product of masses and inversely proportional to the square of the distance between them.

Hence, the two quantities are used to predict gravitational force according to Newton's law of universal gravitation are mass and distance.

How many valence electrons are in N2O? SeCl2? PBr3?
8090 [49]
Here is the answer for the three of them
<span>N20 = 16 e-
</span><span>SeCl2 =20
</span><span>PBr3 = 26 
Remember that t</span><span>o find the valence electrons in an atom you need to identify what group the element is in. An element in group 1A has 1 valence electron. If the element is in group 2A, then it has two valence electrons.</span>
