A solution has a concentration of 40 g.L-1

Chemistry
1 answer:
Bezzdna [24]3 years ago
7 0

Answer: The new concentration is 20 g/L

Explanation:

According to the dilution law,

C_1V_1=C_2V_2

where,

C_1 = concentration of stock solution = 40 g/L

V_1 = volume of stock solution = 20 ml = 0.02 L

C_2 = concentration of diluted solution= ?

V_2 = volume of diluted solution= 40 ml = 0.04 L  

40g/L\times 0.02L=C_2\times 0.04L

C_2=20g/L

Thus new concentration is 20 g/L

How many “p” orbital in principal energy level below?​
marshall27 [118]

Answer:

Each principal energy level above the first contains one s orbital and three p orbitals. A set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. Therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

Three carbon atoms are linked by single covalent bonds such that they form the shape of a V. All of the unshared electrons form
Nostrana [21]

Answer:

C) 8

Explanation:

Total number of carbon atoms = 3

Number of single bonds = 3

So, each carbon is bonded to the next carbon with the single bond, Number of unshared electrons left with the terminate carbons are 3 and with the intermediate carbon is 2.

Thus, the two terminate carbon have 3 hydrogen each and the intermediate will have 2.

<u>Total - 8</u>
