The correct option for above statement is

It is made of atoms that are covalently bonded together.

Explanation:

A substance particle, conjointly referred to as a molecular particle, may be a charged chemical species (ion) composed of 2 or a lot of atoms covalently secured or of a metal complicated that may be thought-about to be acting as one unit. The word poly- suggests that "many," in Greek, however even ions of 2 atoms are ordinarily noted as substance.

When cac2 reacts with water, what carbon-containing compound forms? when reacts with water, what carbon-containing compound form

meriva

Notice that each reactant is made up of two elements. To predict the products, all you have to do is interchange the combination of the two reactants while taking note that metal comes first, followed by nonmetals. With that being said, the reaction would be:

CaC₂ + 2 H₂O --> C₂H₂ + Ca(OH)₂

So, the answer is C₂H₂.

A solution is made by dissolving 85.0 mL of sodium fluoride to water until the final volume is 350.0 mL. Identify the solute in

Natasha_Volkova [10]

Answer:

Sodium fluoride

Explanation:

A solution is constituted by two parts: the solute and the solvent (there may be more than 1 solute and more than 1 solvent, but that is not the key of the answer).

Solute is the substace that is dissolved and it is in less amount than the solvent.

Solvent is the substance that can dissolve the solute and it is a greater amount than the solute.

In the given solution:

sodium fluoride, 85.0 mL, is the solute,
water, 350.0 mL is the solvent, and
the mixture of both substances is the solution.
