Answer:
The flocculation basin often has a number of compartments with decreasing mixing speeds as the water advances through the basin. ... This compartmentalized chamber allows increasingly larger floes to form without being broken apart by the mixing blades.
Answer:
Anything that cannot be separated physically or chemically is an element.
I believe it is B. I’m sorry if i’m wrong. Tell me if i’m wrong or right!
Answer:
BaN, Ba₃N₂
Explanation:
In order to determine the empirical formula of a compound, we have to follow a series of steps.
Step 1: Determine the percent composition
Step 2: Divide each percentage by the atomic mass of each element
Step 3: Divide all numbers by the smallest one
Step 4: If necessary, multiply by a number so the coefficients are whole
Compound 1
Step 1
Ba: 90.745%
N: 100% - 90.745% = 9.255%
Step 2
Ba: 90.745/137.33 = 0.66078
N: 9.255/14.01 = 0.6606
Step 3
Ba: 0.66078/0.6606 ≈ 1
N: 0.6606/0.6606 = 1
The empirical formula is BaN.
Compound 2
Step 1
Ba: 93.634%
N: 100% - 93.634% = 6.366%
Step 2
Ba: 93.634/137.33 = 0.68182
N: 6.366/14.01 = 0.4544
Step 3
Ba: 0.68182/0.4544 = 1.5
N: 0.4544/0.4544 = 1
Step 4
Ba: 1.5 × 2 = 3
N: 1 × 2 = 2
The empirical formula is Ba₃N₂.
If the hydrate gets too hot it could start splattering and cause a loss of sample.
