The empirical formula for a compound composed of 0.0683 mol of carbon ( C ), 0.0341 mol of hydrogen ( H ), and 0.1024 mol of nitrogen ( N ) is 
.
<h3>What is the empirical formula?</h3>
An empirical formula tells us the relative ratios of different atoms in a compound.
Given data:
Moles of carbon = 0.0683 mol
Moles of hydrogen = 0.0341 mol
Moles of nitrogen = 0.1024 mol
Dividing each mole using the smallest number that is divided by 0.0341 moles.
We get:
Carbon= 2
Hydrogen=1
Nitrogen=3

Answer: False
Explanation: the answer is false
Answer:
Some forces cause objects around us to move
A) The answer to whether an average-size, single-family home be built with one day’s output from the saw mill is; No, it can't be built from one days output
B) The number of days will it take for the saw mill to produce enough lumber to build a neighborhood of 100 average-size homes is; 1100 days
A) From research, the average size capacity saw mill usually produces around 1500 board feet of boards per day.
Now, converting board ft to cubic meter gives;
1 board feet = 1/424 m³
Thus; 1500 board feet = 1500 * 1/424 ≈ 3.54 m³
Now, we are told that it takes 38 m³ of boards and plywood to build an average size single family home.
Since one days output = 3.54 m³
It is less than the volume required for the average sized house and so the daily output will not be sufficient.
B) Number of days to produce enough boards and plywood for the average sized family home = 38/3.54 ≈ 11 days
Thus, for 100 homes;
Number of days = 100 * 11 = 1100 days

Answer:
A. 5.5 × 10⁻¹⁰ M, acidic
Explanation:
Step 1: Given data
Concentration of H₃O⁺: 1.8 10⁻⁵ M
Step 2: Calculate the concentration of OH⁻
We will use the ionic product of water.
Kw = 1.0 × 10⁻¹⁴ = [H₃O⁺] × [OH⁻]
[OH⁻] = 1.0 × 10⁻¹⁴/[H₃O⁺] = 1.0 × 10⁻¹⁴/1.8 10⁻⁵ = 5.5 × 10⁻¹⁰ M
Step 3: Determine if the solution is acidic, basic or neutral
- If [H₃O⁺] > 10⁻⁷ M, the solution is acidic.
- If [H₃O⁺] = 10⁻⁷ M, the solution is neutral.
- If [H₃O⁺] < 10⁻⁷ M, the solution is basic.
Then, the solution is acidic.
