Answer: The probability of white puppies is Zero.
Genotype of the black dog is BB. This is a dominant trait, meaning that the presence of a single dominant allele ( Bb) will also give black color.
The genotype of white dog is bb. This is a recessive trait. It means that dog will express white color only if it is homozygous recessive ( bb).
When BB mates with bb, it results in all black puppies. This is so because the genotype of all puppies is Bb. Refer the Punnett square for this.
Thus, the probability that the match will produce white puppies is zero.
<u>Answer:</u> The volume of solution is 195.8 mL
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:
We are given:
Molarity of solution = 0.575 M
Given mass of nickel (II) acetate = 19.9 g
Molar mass of nickel (II) acetate = 176.8 g/mol
Putting values in above equation, we get:
To prepare 0.575 molar nickel (II) acetate solution, we need to add 19.9 grams of nickel (II) acetate to 195.8 mL of solution.
Hence, the volume of solution is 195.8 mL
Answer:
The correct answer is = 31.04
Explanation:
The relation between volume, temperature and pressure of a fix amount of a gas can be expressed by the combined gas law:
PV/T = k
It can be written as well as
P1V1/T1 = P2V2/T2
Given:
V1 = 217.6
P1 = 9.011 atm
T1 = 127.8°C = 400.95 K
P2 = 44.9
T2 = 11.9 °C = 285.05
Solution:
Putting value in the formula
V2 = P1V1T2/P2T1
= (217.6*285.05*9.011)/44.9*400.95
V2 = 31.04
Answer:
The standard heat of formation of Compound X at 25°C is -3095.75 kJ/mol.
Explanation:
Mass of compound X = 7.00 g
Moles of compound X =
Mass of water in calorimeter ,m= 35.00 kg = 35000 g
Change in temperature of the water in calorimeter = ΔT
ΔT = 2.113°C
Specific heat capacity of water ,c= 4.186 J/g °C
Q = m × c × ΔT
Heat gained by 35 kg of water is equal to the heat released on burning of 0.100 moles of compound X.
Heat of formation of Compound X at 25°C:
= -3095.75 kJ/mol
Answer:
ridgid, fixed shape, and fixed volume
Explanation:
solid are all the thing listed as the answer because, you should know solids are not bendable. Therefore they must be very hard.
