Chemistry

NISA [10]3 years ago

4 0

Answer: K+ and P 3−

Explanation:

Electrostatic force of attraction is the attraction between different molecules that comes from them being electrically charged.

For molecules to have an electrostatic force of attraction, they need to have opposing charges because like charges repel each other but opposite charges attract.

In the question above, the only option that has opposing charges is option D so this is the correct option.

luda_lava [24]

Answer:

The equation $\frac{[HI]^{2} }{[H_{2}[I_{2} ] }$ represent

(1) law of mass action

(2) mass action expression

(3) equilibrium constant expression

Explanation:

At a given temperature, the rate of a reaction at a particular instant is proportional to the product of the active masses of the reactants at that instant raised to powers which are numerically equal to the numbers of their respective molecules in the stoichiometric equation describe the reaction.

Chalcopyrite, the principal ore of copper (Cu), contains 34.63 percent Cu by mass. How many grams of Cu can be obtained from 7.3

DENIUS [597]

Answer:

$2.55\times 10^{6}g$ Cu can be obtained from $7.35\times 10^{3}kg$ ore

Explanation:

1 kg = 1000 g

So, mass of ore is $(7.35\times 10^{3}\times 1000)g$ = $7.35\times 10^{6}g$

Now, 100 g of ore contains 34.63 g of Cu

So, $7.35\times 10^{6}g$ ore contains $\frac{(34.63g)\times (7.35\times 10^{6}g)}{100g}$ Cu or $2.55\times 10^{6}g$ Cu.

C is not an example.

explanation: Mass is a physical property as the law of conservation of mass states mass is neither created nor destroyed in a chemical reaction or physical transformation. Chemical reactions are a change in the molecular structure of the product.
