Answer:
This is required answer.
Explanation:
Given that:
1. by addition the ammonia to acetic acid
using balanced chemical equation:
ammonium acetate:
The balanced equation is:
NH₃ + H₂O ===> NH₄OH
when ammonia gas dissolves in water then we get the base in form of ammonium hydroxide.
When NH₄OH reacts with CH₃COOH then we get ammonium acetate and water
NH₄OH + CH₃COOH ===> [CH₃COO]- & NH₄+ & H₂O
So, we can say that,
when we are adding an acid and a base together then we get the product of H₂O and given elements.
2. addition of barium hydroxide to sulfuric acid:
The balanced equation is :
H₂SO4+ Ba(OH)₂--> BaSO₄+ 2H₂O
when acid and base reacts together than we get barium sulphate and water
when sulfuric acid and barium hydroxide.
Hence, this is required answer.
Answer:
Different types of rocks have different chemical composition.
Explanation:
Rock can be distinguished from each other by their chemical composition which is a product of the minerals they contain.
- A rock is an aggregate of minerals.
- Different suites of rocks have their inherent mineralogical composition and facie.
- This is because, these rocks form under different types of conditions from time to time.
- Igneous rocks form from molten rocks, sedimentary rocks form from pre-existing rocks and metamorphic rocks for under elevated temperature and pressure conditions.
- All these conditions plays important roles in the differentiation of minerals in the rock.
The amount of heat needed to vaporize the given amount of water is the product of the amount in grams and the latent heat of vaporization in cal per gram. That is,
H = (540 calories / gram)( 500 grams) = 270,000 cal
Thus, the heat needed is 270, 000 calories. The answer is letter C.
