Can not be D or B and A is not enough so C is right.
No, They need something to hold on to, such as dirt
Answer:
Mass = 2.12 g
Explanation:
Given data:
Volume of KMnO₄ = 255 mL (255/1000 = 0.255 L)
Molarity = 0.0525 M
Mass in gram = ?
Solution:
First of all we will calculate the number of moles.
<em>Molarity = number of moles of solute / volume in litter</em>
0.0525 M = number of moles of solute / 0.255 L
Number of moles of solute = 0.0525 M ×0.255 L
Number of moles of solute = 0.0134 mol
Mass in gram:
<em>Number of moles = mass/ molar mass</em>
Mass = moles × molar mass
Mass = 0.0134 mol × 158.04 g/mol
Mass = 2.12 g
Answer:
faulse

this is an example of a change in proporties
Answer:
The number-average molecular weight for a poly(vinyl chloride) is 1,343,750 g/mol.
Explanation:
Molecular weight of the poly(vinyl chloride),
Number average molecular weight of the polymer = M_a
Degree of polymerization = n = 21500
The number-average molecular weight for a poly(vinyl chloride) is 1,343,750 g/mol.
