M1V1 = M2V2
.200 (.025) = 1.60 X 10 -2 (V2)
V2 = .315 L
1.60 x 10-2 M in 315 mL
Answer:
A
Explanation:
Because it got smaller so that mean it had a chemical reaction
Answer:
D. association with bacterial species.
Explanation:
Methanogens -
These are the organisms , that falls under the category of the prokaryotes , in the domain archaea .
Methanogens are a type of microorganism , which is capable to produce methane as one of the by product during a hypoxic condition .
These organisms are found in the wetland , inside the digestive system of the humans and animals .
They have an important space for the treatment of the anaerobic wastewater .
Hence , from the question ,
The correct option is d.
Answer:
11.6 mL of 0.1400 M of NaOH is required to reach equivalence point.
Explanation:
Chloroacetic acid is an monoprotic acid.
Neutralization reaction:
So, 1 mol of chloroacetic acid is neutralized by 1 mol of NaOH.
Molar mass of chloroacetic acid = 94.5 g/mol
So, 0.154 g of chloroacetic acid = moles of chloroacetic acid
= 0.00163 moles of chloroacetic acid
Lets assume V mL of 0.1400 M of NaOH is required to reach equivalence point.
So, number of moles of NaOH needed to reach equivalence point
= moles
So,
or, V = 11.6
Hence, 11.6 mL of 0.1400 M of NaOH is required to reach equivalence point.
