<em>Answer:</em>
- Conc. of K+ ions = 0.90 M
- Coc. of SO4∧-2 = 0.45 M
<em>Explanation:</em>
<em>Data Given:</em>
Conc. of H2SO4 = 0.450
As sulphoric acid is a strong electrolyte, it completely dissociate into ions.
H2SO4 ⇆ 2K+ + SO4∧-2
.450 M K2SO4 means that there is .450 mols of K2SO4 in every liter of solution.
K2SO4 : K+ K2SO4 : SO4∧-2
1 = 2 1 = 1
0.450 = 2× 0.450 = 0.90 0.450 = 0.450×1 = 0.450
<em> Result:</em>
Conc. of potassium ion will be 0.90M
Coc. of sulphate ions will be 0.45 M
Explanation:
Plants are autotrophic organisms which prepare their food with the help of photosynthesis. Plants can have both asexual or multi-sexual reproduction.
Amoeba is a single celled eukaryotic organism. It moves through pseudopodia and it does not have any definite shape. Amoeba can have only asexual reproduction.
The given functions for amoeba and plants are sorted as follows.
Functions of Amoeba:
- has only offspring with identical genes and traits.
- surrounds and engulfs food particles.
- move freely in their environment.
Functions of Plants:
- makes food from carbon dioxide,water, and sunlight.
- can have offspring with different genes and traits.
Explanation:
Boiling point is defined as the point at which liquid state and vapor state of a substance are existing in equilibrium.
Equilibrium is defined as the state in which rate of forward and rate of backward reaction are equal to each other.
For example, 
So, when we boil bromine which is present in liquid state then at the boiling point its vapors will exist in equilibrium. And unless all the liquid state of bromine will not convert into vapors its temperature will not change.
Therefore, we can conclude that at boiling point the liquid and the vapur of Bromine are in equilibrium.
Answer:
1 = strontium
2 = technetium
3 = silver
Explanation:
Strontium is present in 2 group of periodic table. It is alkaline earth metal. It is most reactive element and can not found free in nature. it is insoluble in water but react with water and form strontium hydroxide and hydrogen gas is also produced. It is radioactive element.
It is similar to the calcium and can incorporated into bones. The food rich with strontium is used to avoid the osteoporosis. It is found in leafy vegetables, grains, sea foods etc.
In given series strontium is highest in reactivity then technetium, while the technetium is more reactive than silver. The silver is less reactive as compared to both given elements.
It blocks light waves from passing through.
