Answer:

Yes. Ca²⁺(aq) + SO₄²⁻(aq) ⟶ CaSO₄(s)

Step-by-step explanation:

The possible reaction is

CaI₂ + Na₂SO₄ ⟶ CaSO₄ + 2NaI

To predict a reaction, you must know <em>the solubility rules</em>.

The important ones for this question are

  1. Salts containing Na⁺ are <em>soluble</em>. Thus, NaI is soluble.
  2. Most sulfates are soluble, but CaSO₄ is not. Thus, CaSO₄ is a precipitate, and a reaction occurs.

Molecular equation

CaI₂(aq) + Na₂SO₄(aq) ⟶ CaSO₄(s) + 2NaI(aq)

Ionic equation

Ca²⁺(aq) + <u>2I⁻(aq)</u> + 2Na²⁺(aq) + SO₄²⁻(aq) ⟶ CaSO₄(s) + 2Na⁺(aq) + 2I⁻(aq)

Net ionic equation

Cancel all ions that appear on both sides of the reaction arrow (underlined).

Ca²⁺(aq) + <u>2I⁻(aq) </u>+ <u>2Na²⁺(aq)</u> + SO₄²⁻(aq) ⟶ CaSO₄(s) + <u>2Na⁺(aq)</u> + <u>2I⁻(aq) </u>

The net ionic equation is

Ca²⁺(aq) + SO₄²⁻(aq) ⟶ CaSO₄(s)

Ph measures how acidic or basic something is. The lower the number the more acidic it is going to be.

Drink A is basic, he can drink that

Drink B is neutral, he can drink that

Drink C is acidic, he should avoid

Drink D is basic, he can drink that

Drink E is acidic, he should avoid

How could the survivors about starting a fire?
joja [24]

Answer:

The ancient Greeks believed that fire was one the four basic elements that composed all things in the universe. In the mythology of virtually every culture, fire is a sacred substance that gives life or power. Fire is not, in fact, a substance. When you gaze at the leaping flames of a campfire, you’re observing not an object, but a process – a chemical reaction. It’s the same chemical reaction that occurs when a cut apple left on the counter turns brown, when silver tarnishes or when an iron nail rusts.

That process is oxidation: combining oxygen with another substance. The defining difference between a fire and your half-eaten apple is speed: fire is an oxidation process that happens very fast, so that light, heat and sound are released — often with enough force and majesty to justify the ancients’ reverence.The sudden release of energy causes temperatures to rise, sometimes by thousands of degrees. And it also results in smoke, the toxic waste of fire’s leftovers.

Fire TetrahedronThe fire triangle identifies the three needed components of fire:

fuel (something that will burn)

heat (enough to make the fuel burn)

and air (oxygen)
