Answer:
There is ionic bonding between Mg2+ ions and NO3− ions. Which of the following claims about a binary compound in which the bonding is ionic is most likely to be scientifically valid? Both elements in the compound are metals.
moles Al = 5 moles * 2 = 10 moles Al
moles S = 5 moles * 3 = 15 moles S
moles O = 5 moles * 12 = 60 moles O

Answer:
Esters are both inorganic and organic acids .... Regarding the second question, it is believed that it is carried out in this way in order to recognize the C-terminal amino acid in a peptide within a protein
Explanation:
The explanation of this question is according to what was interpreted in the question, since it is considered that it is poorly written ...
What happens in this chemical reaction is that it first becomes an ester (organic or inorganic acid) so that it is later recognized in the complex peptide structure.
Answer:
Higher the inter particles forces of attraction, higer the melting point.
Based on this wish you can arrenge them in a required order.

Answer:
0.036 × 10²³ oxygen atoms
Explanation:
Given data:
Mass of compound = 0.24 g
Number of oxygen atoms = ?
Solution:
First of all we will calculate the number of moles of compound.
number of moles = mass/ molar mass
Number of moles = 0.24 g/ 100.1 g/mol
Number of moles = 0.002 mol
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole of CaCO₃ contain 3 moles of oxygen atom.
0.002 mol × 3 = 0.006 moles of oxygen atoms.
Number of oxygen atoms:
1 mole = 6.022 × 10²³ number of oxygen atoms
0.006 mol × 6.022 × 10²³ f oxygen atoms / 1 mol
0.036 × 10²³ oxygen atoms
