14 Molar is its molarity.
Answer:
The solute is the substance being dissolved.
The solvent is the substance dissolving the solute.
Therefore, the salt is the solute and the water is the solvent.
Explanation:
The salt is the solute.
Answer:
Temperature
PH
Explanation:
Enzymes are organic catalysts that speeds up the rate of a chemical reaction. Their activities are affected by temperature and pH of the environment among other factors.
- At extreme temperatures, enzymes can easily be denatured and they will cease to act.
- At extremes of pH, they can also be adversely affect.
Enzymes generally have temperature and pH window for their activity.
Answer:
6m 48cm
Explanation:
First we can convert the length of Mac's bedroom to centimeters:
As<em> 1 m is equal to 100 cm</em>,
- 3m 59cm is equal to 300 cm + 59 cm = 359 cm.
As for Dennis' bedroom's information:
Now we can calculate the length of Dennis' bedroom:
Rewriting the answer leaves us with 6m 48cm.
Answer:
CuNO3
Explanation:
In order to calculate the empirical formula in this question;
Cu = 50.61% = 50.61g
N = 11.16% = 11.16g
O = 38.23% = 38.23g
Next, we convert each gram unit to moles by dividing by their respective molar mass (Where; Cu = 63.55, N = 14, O = 16)
Cu = 50.61 ÷ 63.55 = 0.796mol
N = 11.16 ÷ 14 = 0.797mol
O = 38.23 ÷ 16 = 2.389mol
Next, we divide each mole value by the smallest (0.796)
Cu = 0.796mol ÷ 0.796 = 1
N = 0.797mol ÷ 0.796 = 1.001
O = 2.389mol ÷ 0.796 = 3.001
Approximately, the simple whole number ratio between Cu, N and O is 1:1:3, hence, the empirical formula is CuNO3.
