Hey there!:
mass = 41.2 g
Volume = 8.2 cm³
Therefore:
D = m / V
D = 41.2 / 8.2
D = 5.02 g/cm³
The mass of ONE mole is the same thing as the atomic mass, so the mass of one mole of Al is 26.99
Genetics cause these disorders, after the trait is passed down to the offspring
Answer: f. 2:2:2:1
Explanation: The reaction is a single displacement where Cs displaces H to pair up with OH.
The balance chemical equation is:
2 Cs + 2 H2O => 2 CsOH + H2
The number of atoms on both sides are equal.
Cs= 2
H= 4
O= 2
It belongs to the “s-block”
