Answer:
True
Explanation:
The arrangement of three groups COOH, CO, OH in the order of reducing boiling point is as follow -
COOH > OH > CO
COOH gets strongly polarised due to the presence of electron withdrawing carboxy group and hence have strong H+ bonds as compared to that of alcohol.
Hence the given statement is true.
Answer:
0.192 mol.
Explanation:
- To calculate the no. of moles of a substance (n), we use the relation:
<em>n = mass / molar mass.</em>
mass of AsH₃ = 15.0 g.
molar mass of AsH₃ = 77.95 g/mol.
∴ The number of moles in 15.0 g AsH₃ = mass / molar mass = (15.0 g) / (77.95 g/mol) = 0.192 mol.
A solar panel works by talking in light and transforming it into energy and a windmill collects kinetic energy to transform it into energy.
Answer: They ionize by the gain of one electron
Explanation:
Group 7 elements have seven electrons on their outermost shell, in order to have a complete octet structure, the go into bonding with other elements by gaining one more electron to have eight complete outermost shell electron (valence electron). They thereby ionize by gain one electron forming X
