Answer: C) 330 g

Explanation: Since all the masses are given in different units, it's good to make all of them to have same unit. Let's say we convert all of them to grams.

A) kg stands for kilogram and 1 kg = 1000 g

So, 0.033kg(\frac{1000g}{1kg})

= 33 g

B) hg stands for hactogram and 1 hg = 100 g

So, 0.33hg(\frac{100g}{1hg})

= 33 g

C) 330 g

D) cg stands for centigram and 1 cg = 0.01 g

So, 3300cg(\frac{0.01g}{1cg})

= 33 g

Looking at all the choices, choice A, B and D represent equal amount of matter that is 33 g where as choice C represents 330 g of matter.

Hence, the correct choice is C) 330 g.

We can skip option B and D because NaCl is salt and H₂SO₄ is a strong acid.
Neutralization reactions are those reactions in which acid and base react to form salt and water.
As water being amphoteric in nature can react with HCl as follow,

                           HCl  +  H₂O   ⇆  H₃O⁺  +  OH⁻

In this case no salt is formed, so we can skip this option.

Ammonia being a weak base can abstract proton from HCl as follow,

                              HCl  +  NH₃  →  NH₄Cl

Ammonium Chloride is a salt. So, among all four options, Option-C is the correct answer.

Why is it important for people to understand how to properly dispose of waste in a watershed?
Natali [406]

Answer:

disposing waste properly is important because watersheds are the surface water features and stormwater runoff within a watershed which ultimately end up in other bodies of water. It is essential to consider these downstream impacts when developing and implementing water quality protection and restoration actions. Everything upstream ends up downstream

Explanation:

A watershed describes an area of land that contains a common set of streams and rivers that all drain into a single larger body of water, such as a larger river, a lake or an ocean. For example, the Nile River watershed is an enormous watershed
