Hey there!

Using your density formula, D=M/V where D represents the density, M represents the mass, and V represents the volume, you can plug in your given values to find the density.

Knowing that your mass is 7.92 grams, and your volume is 3.25 mL, you can find the density by setting up this expression:
7.92/3.25

Now, simplify:
7.92/3.25
≈2.44

Therefore, your density of the object would be approximately 2.44 grams per mL.

Hope this helps and have a marvelous day! :)

Which of the following reactions Shows a chemical change producing a gas? APEX

Nina [5.8K]

Answer: $2CH_3OH(l)+3O_2(g)\rightarrow2CO_2(g)+4H_2O(l)$

Explanation: A chemical change is a reaction in which chemical composition of the substance changes. Some bonds are broken and some new bonds are formed.

The reactants are written in terms of their chemical formula on the left hand side and the products are written in terms of their chemical formula on right hand side with a arrow in between. The chemical symbols are followed by their physical states such as (l) for liquid, (s) for solid, (g) for gas and (aq) for aqueous.

Thus the only reaction producing a gas is $2CH_3OH(l)+3O_2(g)\rightarrow2CO_2(g)+4H_2O(l)$
