Answer:
Yes
Explanation:
A small part of the correspondence is due to the relationship between temperature and the solubility of carbon dioxide in the surface ocean, but the majority of the correspondence is consistent with a feedback between carbon dioxide and climate.
Answer:
true
Explanation:
I'm not sure why cause I dont know how to explain but it's TRUE
Explanation:
The problem here is to find the atomic number of each of the element given.
Sum the powers of the configuration.
a- 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹
Atomic number is = 2 + 2 + 6 + 2 + 6 + 1 = 19
b- 1s² 2s² 2p⁶ 3s² 3p⁴
Atomic number = 2 + 2 + 6 + 2 + 4 = 16
c- 1s¹
Atomic number = 1
Phosphorus, Chlorine. The IUPAC name is Phosphorus pentachloride
Explanation:
The given data is as follows.
Boiling point of water (
= (100 + 273) K = 323 K,
Boiling point of solution (
= (101.24 + 273) K = 374.24 K
Hence, change in temperature will be calculated as follows.

= 374.24 K - 323 K
= 1.24 K
As molality is defined as the moles of solute present in kg of solvent.
Molality = 
Let molar mass of the solute is x grams.
Therefore, Molality = 
m =
= 
As, 

x = 
= 1321.29 g
This means that the molar mass of the given compound is 1321.29 g.
It is given that molecular formula is
.
As, its empirical formula is
and mass is 30 g/mol. Hence, calculate the value of n as follows.
n = 
= 
= 44 mol
Thus, we can conclude that the formula of given material is
.
