**Answer:**

I would suggest the answer D: A paint manufacturer

**Explanation:**

I think 1) acidic solution

2) basic solution.

The answer if Na2O. Explanation: When you write the formula, write such a way that the compound is neutral. Since Na has 1+ charge and O has 2- charge, you need 2 Na to balance the 2- charge of O. Easy way to do this is to criss-cross the charge of the atoms as the subscripts in the formula. Use the simplest integer ratio at the end. Example: 1) Mg^2+ and P^3- Formula: Mg3P2 2) Ca2+ and O2- Formula: Do not write as Ca2O2. Instead write as CaO 3) Al^3+ and O^2- Formula: Al2O3.

ANSWER: Na20

mark me brainlist please

**Answer:**

WAIT, first find out how they got those awnsers

**Explanation:**

**Answer: The possible molecular formula will be **

**Explanation:**

Mass of C= 27.3 g

Mass of O = 72.7 g

Step 1 : convert given masses into moles.

Moles of C =

Moles of O =

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C =

For O =

The ratio of C : O = 1: 2

Hence the empirical formula is

**The possible molecular formula will be=**
