The correct way to write this number in scientific notation : 6.022 x 10²³
<h3>Further explanation
</h3>
Scientific Notation is a standard form of writing numbers used in mathematical operations
The rules:
1. Writing order : first digit, decimal point, next digit
2. Then followed by powers of 10 (the value can be +/-)
If the value is> 10 (the power of 10 is +), the decimal point is moved to the left, to the right of the first digit
If the value is <10 ((the power of 10 is -), the decimal point is moved to the right, to the right of the first digit
I certainly didn't count the details of the number of zeros listed, but only saw the answer choices.
And the right ones are: 6.022 x 10²³
Answer:
the number of neutrons for silicon is 14
53.14 grams of Zn
will be produced from 26.0 g of Zn and 42.0 g of HCl.
Explanation:
Balanced chemical reaction:
Zn + 2 HCl ⇒ Zn + 
data given:
mass of Zn = 26 grams
mass of HCl = 42 grams
mass of Zn = ?
here in the reaction Zn is the limiting reagent so mass of
Zn formed will be determined by it.
atomic mass of zinc =65.38 grams/mole
number of moles = 
putting the values in the above equation:
number of moles of zinc = 
number of moles of zinc = 0.39 moles
From the balanced reaction it is seen that
1 mole of Zn produced 1 mole of Zn
0.39 moles will produce x moles of Zn
0.39 moles of Zn (atomic mass of Zn = 65.38 grams/mole)
mass = atomic mass x number of moles
= 0.39 x 136.28
= 53.14 grams
53.14 grams of Zn is formed
