Answer:

C. Burning oil

Explanation:

Water cannot be used as a fire extinguisher to extinguish the flames of burning oils such as gasoline, petrol, or diesel. Because oil is lighter than water, it floats on top of it and cremates. Furthermore, as the water spreads and carries the oil with it, the fire spreads over a larger area.

I am joyous to assist you at any time.

Is 2 KNO₃ + H₂CO₃ → K₂CO₃ + 4 HNO₃ a balanced equation
krok68 [10]

Hey there!

The elements in this equation are K, N, O, H, and C.

Let's count how many of each are on each side to see if it is balanced.

K: 2 on the left, 2 on the right.

<em>N: 2 on the left, 4 on the right. </em>

<em>O: 9 on the left, 6 on the right. </em>

<em>H: 2 on the left, 4 on the right. </em>

C: 1 on the left, 1 on the right.

Notice that there are different amounts of N, O, and H on the left side and the right side.

This means that the equation is not balanced.

Hope this helps!

In solid NaCl, each sodium ion is surrounded by six chlorine ions and each chlorine ion is surrounded by six sodium ions. This a
kow [346]

Owing to the arrangement of ions in NaCl, the structure has a high melting point and crystalline structure.

Ionic compounds are know to have a crystalline structure. This is because the ions in the compound are arranged into a crystal lattice. A crystal lattice gives a regular repeating structure of ions in the crystal.

As a result of this order in the crystal, the resultant sodium chloride structure has a high melting point and crystalline structure.
