A dominant phenotype will be expressed when at least one allele of its associated type is present whereas a recessive phenotype will only be expressed when both allele are of its associated type.
The molality of H₂SO₄ solution is 24.2 m.
<u>Explanation:</u>
We need to find the molality of sulfuric acid.
Mass of sulfuric acid = 785.6 g
Mass of water = 359 g
We have to find the moles of H₂SO₄ by using its mass and molar mass as,
Moles of H₂SO₄ = 
= 8.7 moles
Mass of the solution in kg =
= 0.359 kg
Molality = 
= 
= 24.2 m
So molality of the H₂SO₄ solution is 24.2 m.
Answer:
Thermosphere
Explanation:
More specifically the ionosphere, since the ionosphere is the lower part of the thermosphere.
Hope this helps!
Answer:
a. K⁺
b. Se²⁻
Explanation:
Isoelectronic species are those that have the same number of electrons.
a.
Ar has 18 electrons. K has 19 electrons, so when it loses 1 electron to form K⁺, it is isoelectronic with Ar.
b.
Kr has 36 electrons. Se has 34 electrons, so when it gains 2 electrons to form Se²⁻, it is isoelectronic with Kr.
There are 2 possible correct answers. Those answers are A and C because atoms "fuse together" by sharing electrons, and both compounds react to water, as they both dissolve in it. I would choose C as my answer, though.
