It is the renal pelvis that acts as a funnel to pas the urine that is produced in several nephrons to the ureters. The correct answer is C.
Answer:
D
Explanation:
Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs.
You can identify the unmarked poles of a magnet using different techniques.
1) Get a marked magnet to know the north and south poles of the unmarked magnet. North of the marked magnet attracts the south of another magnet.
2) Using a compass - the north of the unmarked magnet aligns tot he north of the compass
The alkalinity as CaCO3 in mg/L is 108,23
<h3>What is alkalinity?</h3>
Alkalinity is the total measure of substances present in water, capable of neutralizing acids. In other words, it is the amount of substances present in the water that act as a buffer.
With that being said;
Equivalent weight = {molar mass}*{ion charge/oxidation number}
- Molar mass of HCO3- = 61g/mol
- Molar mass of CO3 = 60g/mol
- Molar mass of CaCO3 = 100g/mol
- Eq. cot. of HCO3- = 61g/Eq
- Eq. cot. of CO3 = 30g/Eq
- Eq. cot. of CaCO3 = 50g/Eq
Alkalinity due to CO3 = {32x50}{30} = 53.33mg/L
Alkalinity due to HCO3- = {56x50}{61} = 54,90mg/L
Total Alkalinity = 53,33 + 54,90 = 108,23 mg/L
In this case, we have to The alkalinity as CaCO3 in mg/L is 108,23 mg/L
