Answer:
3
Explanation:
From the question:
Barium phosphate reacts with sulfuric acid to form barium sulfate and phosphoric acid.
The equation for the above reaction can be written as follow:
Ba3(PO4)2 + H2SO4 —> BaSO4 + H3PO4
Now, let us balance the equation in order to obtain the coefficient of H2SO4. This is illustrated below below:
Ba3(PO4)2 + H2SO4 —> BaSO4 + H3PO4
There are 3 atoms of Ba on the left side of the equation and 1 atom on the right side. It can be balance by putting 3 in front of BaSO4 as shown below:
Ba3(PO4)2 + H2SO4 —> 3BaSO4 + H3PO4
There are 3 atoms of SO4 on the right side and 1 atom on the left side. It can be balance by putting 3 in front of H2SO4 as shown below:
Ba3(PO4)2 + 3H2SO4 —> 3BaSO4 + H3PO4
Now, we can see that there 6 atoms of H on the left side and 3 atoms on the right side. It can be balance by putting 2 in front of H3PO4 as shown below:
Ba3(PO4)2 + 3H2SO4 —> 3BaSO4 + 2H3PO4
Now the equation is balanced.
The coefficient of sulphuric acid (H2SO4) is 3
The nucleus is effected
Explanation: The nucleus is the main part of it gets weak they all get weak
Air is the most simplest mixture of gas and gas. It contains oxygen, CO2, nitrogen, etc.
The answer is Algae.
<span>Abiotic factors are non-living things of an ecosystem. Abiotic factors include landscape, climate, pH, salinity and other physical features of the ecosystem. On the other hand, there are b</span>iotic factors. Biotic factors are living things in the ecosystem. Those are plants, animals, and other organisms. Since Algae are living-things, they are biotic factors unlike pH, salinity, and climate which are abiotic factors.
