Answer:
The table is useful for modern students and scientists because it helps predict the types of chemical reactions that are likely for an element
Answer:
The molarity of the acid HX is 6.0 M.
Explanation:
We determine the amount of moles of KOH used to neutralize the acid:
=0.12 moles KOH
Then, we calculate the amount of moles of acid:
0.12 moles KOH×
=0.12 moles HX
The molarity of HX is:
=6.0 M
Answer:
1.51 x 10²⁴atoms
Explanation:
Given parameters:
Number of moles of Cr = 2.50mol
Solution;
what is a mole;
a mole of any substance is the amount of substance that contains the avogadro's number of particles which is 6.02 x 10²³ particles
The particles here can be atoms, protons, neutrons, electrons e.t.c
1 mole contains 6.02 x 10²³ atoms
2.5 moles will contain 2.5 x 6.02 x 10²³ = 1.51 x 10²⁴atoms
It gives information to the brain I think I’m not entirely sure !!83
Yeah!
There are 12 inches in a foot.
16.7 in ÷ 12 in = 1.39 ft
Or if you prefer to the nearest tenth:
1.4 ft.
Good luck! :)
