Polar covalent, it is what happens when there is unequal bond between two atoms, where one has a slightly negative charge and one has a slightly positive charge.
Answer:
Atoms of the same element (i.e., atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes. For example, most hydrogen atoms have a single proton in their nucleus.

Explanation:
Hello there!
In this case, according to the given chemical reaction, it is first necessary to compute the moles of reacting LiOH given its molar mass:
Thus, since there is a 1:1 mole ratio between lithium hydroxide and silver nitrate (169.87 g/mol) the resulting milligrams turn out to be:
Best regards!
When 2 moles burn 6 moles of O2 is produced !
so for 16 moles , (6/2)×16= 48 moles will be produced !
so answer is A , 48 moles !
Answer:
The answer to your question is: 6 ml of HCl
Explanation:
1.- Molarity of NaCl in solution
n = # of moles
M = n / volume (l)
n = M x v
n = (0.1) (0.030)
n = 0.003 moles of NaOH
2.- Number of moles of HCl that react
From the reaction 1 mol of NaOH ----------------- 1 mol of HCl
0.003 moles ----------------- x
x = (0.003 x 1) / 1 = 0.003 moles of HCl
3.- Volume of HCl that react
M = n/ V
V = n / M
V = 0.003 / 0.5
V = 0.006 l
V = 6 ml
