The atomic mass would be 13 amu.
You can calculate this by adding the number of protons and neutrons.
7 protons+6 neutrons
=13 amu.
Answer:
67.5 atm
Explanation:
To answer this problem we can use <em>Boyle's law</em>, which states that at constant temperature the pressure and volume of a gas can be described as:
P₁V₁=P₂V₂
In this case:
P₁ = 101.3 atm
V₁ = 0.500 L
P₂ = ?
V₂ = 0.750 L
We input the data:
101.3 atm * 0.500 L = P₂ * 0.750 L
And solve for P₂:
P₂ = 67.5 atm
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.
Balanced chemical reaction: Fe₂O₃<span> + 2Al → 2Fe + Al</span>₂O₃.
Fe₂O₃ is iron(III) oxide.
Al is aluminium.
Fe is iron.
Al₂O₃ is aluminium oxide.
In thermite reaction<span> elemental aluminium reduces the iron (III) oxide or some other metal oxide.
Mole ratios from chemical reaction:
n(</span>Fe₂O₃) : n(Al₂O₃) = 1 : 1.
n(Fe₂O₃) : n(Al) = 1 : 2.
n(Fe₂O₃) : n(Fe) = 1 : 2.
