answer: A not sure but i hope it helps :) success
Solid lead nitrate in water gives lead oxide and nitric acid
Pb(NO3)2 + H2O ---> PbO + 2 HNO3
At STP, the volume of Cl2 is 22.4 L/mol.
11.5 L Cl2 * (1 mol Cl2/ 22.4 L Cl2)= 115/224 mol Cl2.
115/224 mol Cl2* (70.90 g Cl2/ 1 mol Cl2)= 36.4 g Cl2.
The final answer is 36.4 g Cl2.
Hope this helps~
Answer:
Genotypic ratio = 1 Bb: 1 bb
Phenotypic ratio = 1 black rabbit : 1 brown rabbit
Explanation:
This question involves a gene coding for hair color in rabbits. The allele for Black hair (B) is dominant to the allele for brown hair (b).
According to this question, a black rabbit whose mother is brown haired (bb) is crossed with a brown hair rabbit. This means that the black rabbit will have a genotype 'Bb' while the brown rabbit will have a genotype 'bb'. Each parent will produce the following gametes:
Bb - B and b
bb - b and b
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Bb, Bb, bb and bb
This means that the;
Genotypic ratio = 1 Bb: 1 bb
Phenotypic ratio = 1 black rabbit : 1 brown rabbit
