Answer:
0.31 mol K x 39.1 grams K/ 1 mol k = 12.1 g
Explanation:
molar mass of K: 39.1
In order to find the mass in 0.31 mol of K, you must covert moles to grams. In one mole of Potassium there is 39.1 grams.
Answer:
No
Explanation:
Filling a beaker 200ml of water is not bad because Each beaker's capacity may vary according to the size of different beaker.
Reduction is the gain of electrons, then potential of reducción is the tendency of a sustance to gain electrons. In this case the sustance is an electrode.
Then the reduction potential refers to the tendency of one electrode to gain electrons and it is measured against a standard electrode which is the electrode of hydorgen.
When you consider the pair of half-cell reactions, the potential of the cell is the reduction potential - oxidation potential.
Answer:
the dividend yield is 4%
Explanation:
The computation of the dividend yield is as follows:
Dividend yield = Dividend per share ÷ current share price per share
= ($0.20 × 4 quarters) ÷ $20
= $0.80 ÷ $0.20
= 4%
hence, the dividend yield is 4%
The same is determined by applying the above formula
