The chemical formula of the solute is NaNO3. The mass of this is 1.4*85=119 g. The boiling point of the solution is higher than water. The molarity of this solution is 1.4/2=0.7 M.
ansewr i think it is 1 3 5 and 8
Explanation: i did not take it but i hope you the best of luck
Answer: YOU MAY FIND THE ANSWER IF YOU SEARCH THE WEB.
Explanation:
Answer:
The correct answer would be -
17. 50% chances of round offspring
18. 25% chances two copies of dominant allele in the genotype of offspring
Explanation:
17. In this question it is stated that the Spongebob is heterozygous and has a square body which means the square body is dominant over the round that is present in sponge Susie that means she has two copies of the recessive allele.
S for square trait and s for a round trait then
S s
s Ss ss
s Ss ss
Thus, the correct answer is 50 percent as there are only two copies of ss.
18. in this question Patric and Patti both have heterozygous for the pink (P) body-color dominant over yellow (p). The chances for the true-breeding dominant genotype would be -
P p
P PP Pp
p Pp pp
There is only one out of four rue-breeding dominant offspring will be produced.
The initial state of the system is comprised of
(a) A metal sample
m₁ = 43.5 g, mass
T₁ = 100°C, temperature
c₁ (unknown) specific heat, J/(g-C)
(b) Water
m₂ = 39.9 g, mass
T₂ = 25.1°C, temperature
c₂ = 4.184 J/(g-C), specific heat
The final state of the system is
M = m₁ + m₂, total mass
T = 33.5°C, equilibrium temperature
Work in SI units. Note that changes in °C are equal to changes in °K.
Equate change in total thermal energy to zero because the energy is conserved.
m₁c₁(T-T₁) + m₂c₂(T-T₂) = 0
(43.5)*(c₁)(33.5 - 100) + (39.9)*(4.184)*(33.5 - 25.1) = 0
-2892.8c₁ + 1402.3 = 0
c₁ = 1402.3/2892.8
= 0.4848 J/(g-C)
Answer: The specific heat capacity of the metal is 0.485 J/(g-°C)
