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.
The most weight was gained between 0 - 1 years for both boys and girls.
<h3>What is weight?</h3>
- Weight is a vector quantity that varies from place to place to due to effect of gravity.
Average weight of the boys in pounds;
age -------------------- average weight
0 -------------------------50
1 ------------------------- 45
2 ------------------------ 40
3 ------------------------- 35
4 -------------------------- 30
5 -------------------------- 25
Average weight of the girls in pounds;
0 --------------------------------- 20
1 ----------------------------------- 15
2 ------------------------------------ 10
3 --------------------------------------5
4 -------------------------------------- 0
5 --------------------------------------- 1

Answer:
400 K
Explanation:
Charles's law states:
A determined volume of a gas is directly proportional to its temperature, while we have constant pressure.
V₁ / T₁ = V₂ / T₂
We replace data:
5 L / 100K = 20L / T₂
T₂ = 20L . 100K / 5 L
T₂ = 400 K
The volume was quadrupled, so the temperature did.
If we want T° at Celsius degree:
400 K - 273 = 127°C

There is an overall negative charge for the ion due to the additional unbonded electron on the second oxygen atom. The electrons, although not favored, can form an oxygen-oxygen double bond, as a resonance structure.</span>
Answer:
92.6 g.
Explanation:
- The balanced equation is:
CaC₂ + N₂ → CaCN₂ + C.
- It is clear that 1.0 mole of CaC₂ reacts with 1.0 mole of N₂ to produce 1.0 mole of CaCN₂ and 1.0 mole of C.
- We need to calculate the no. of moles of 265.0 g of CaCN₂ produced using the relation:
n = mass / molar mass = (265.0 g) / (80.102 g/mol) = 3.308 mol.
- We should get the no. of moles of N₂ needed to produce 3.308 mol of CaCN₂.
∵ 1.0 mole of N₂ produces → 1.0 mole of CaCN₂.
<em>∴ 3.308 mole of N₂ produces → 3.308 mole of CaCN₂.</em>
- Now, we can get the grams of N₂ consumed to produce 265.0 g of CaCN₂:
∴ The grams of N₂ = n x molar mass = (3.308 mole)(28.0 g/mol) = 92.63 g = 92.6 g.
