Answer:

(a) Acid

(b) Base

(c) Acid

(d) Base

Explanation:

According to the Arrhenius acid-base theory:

  • An acid is a substance that releases H⁺ in aqueous solution.
  • A base is a substance that releases OH⁻ in aqueous solution.

(a) H₂SO₄ is an acid according to the following equation:

H₂SO₄(aq) ⇒ 2 H⁺(aq) + SO₄²⁻(aq)

(b) Sr(OH)₂ is a base according to the following equation:

Sr(OH)₂(aq) ⇄ Sr²⁺(aq) + 2 OH⁻(aq)

(c) HBr is an acid according to the following equation:

HBr(aq) ⇒ H⁺(aq) + Br⁻(aq)

(d) NaOH is a base according to the following equation:

NaOH(aq) ⇒ Na⁺(aq) + OH⁻(aq)

Reason the Carbon Cycle is necessary to sustain life on Earth
____ [38]
<span>Most living things on Earth are made of carbon.


Living things need carbon in order to live, grow, and reproduce.


Carbon is a finite resource that cycles through the Earth in many forms.


This makes carbon available to living organisms and remains in balance with other chemical reactions in the atmosphere and in bodies of water like ponds and oceans.</span>

Click oil basics to explore the natural resources needed for the production of plastics. use the information to answer the quest
GaryK [48]

The ingredients that is important in making plastics is natural gas plant liquids.

Natural gas liquids (NGLs) are components of natural gas which are separated from the gas state in the form of liquids. They many applications including; plastic production, inputs for petrochemical plants, they are also burned for space heat and cooking, and can also be blended into vehicle fuel.

In the manufacturing of plastics, come components of NGLs are used. And for this case, ethane. Ethane is used in the production of ethylene which are passed through pressure and catalyst to be turned to plastics like polythene.

The reason why they are mostly used in the manufacturing plastics than other resources like crude oil is that it is much cleaner.

What are three units you can measure moler mass in
liraira [26]

By looking at a periodic table, we can conclude that the molar mass of lithium is 6.94g, the molar mass of zinc is 65.38g, and the molar mass of gold is 196.97g. Each of these quantities contains 6.02×1023 atoms of that particular element. The units for molar mass are grams per mole, or g/mol.

So The answers are Lithium, Gold, Zinc
