The answer is A. Remember that meiosis is like sexual reproduction and mitosis is like asexual reproduction. Hope this helps!
An element is composed of a single type of cell. So we can expect only one kind of element. For example if it is a carbon element it will contain only carbon atoms.
Answer:
96 g of O
Explanation:
Mg(OH)₂ → Magnesium hydroxide
Molar mass → 24.3g/mol . 1 + 16g/mol . 2 + 1g/mol . 2 = 58.3 g/mol
We determine the moles of hydroxide → 175 g . 1mol/58.3g = 3 moles
Let's make some rule of three:
In 100 g of compound we have 54.87 g of O
In 58.3 g of compound we may have (58.3 . 54.87) / 100 = 32 g
So, 1 mol of hydroxide has 32 g of oxygen
3 moles of hyroxide may have (3 .32)/1 = 96 g of O
Answer:
The motion of the gas particles is random and in a straight-line. A sample of gas is contained in a closed rigid cylinder.
I hope this helps you if not soo advance sorry :)
Explanation:
Formula for compressibility factor is as follows.
z =
where, z = compressibility factor for helium = 1.0005
P = pressure
= molar volume
R = gas constant = 8.31 J/mol.K
T = temperature
So, calculate the molar volume as follows.
=
= 0.0056
As molar mass of helium is 4 g/mol. Hence, calculate specific volume of helium as follows.
=
= 0.00139
= 0.00139
= 1.39
Thus, we can conclude that the specific volume of Helium in given conditions is 1.39 .
