Answer:
To find the volume of the gas. So if you have the amount of gas in moles. So the first step is to multiply the amount of moles that is 2.4 with liters to find the answer.
Explanation:
Answer:
flourine 19F-
Explanation:
because we have 1 extra electron so the charge should be negative, then check the number of protons to know the atomic number, and 9 is flourine
Answer:
0.2M H2C6H5O7 < 0.2M H2C2O4
Explanation:
A weak acid/base ionizes to a very small extent in water. Hence, if we say that a substance is a weak acid/base, its percentage of ionization in solution is very little.
More volume of a very weak acid is required to neutralize a strong base. Since NaOH is a strong base, the weaker acid among the duo will require more volume for neutralization.
Since H2C6H5O7 is a weaker acid than H2C2O4, equal concentration of the both acids will require less volume of H2C2O4 than H2C6H5O7 to neutralize 0.50 M NaOH.
Answer : The volume of NaOH stock solution used should be, 250 ml
Solution :
According to the neutralization law,
where,
= molarity of NaOH solution = 0.50 M
= volume of NaOH solution = 3.0 L
= molarity of NaOH stock solution = 6.0 M
= volume of NaOH stock solution = ?
Now put all the given values in the above law, we get the volume of NaOH stock solution.
(1 L = 1000 ml)
Therefore, the volume of NaOH stock solution used should be, 250 ml
Answer:
Answer to the following question is as follows;
Explanation:
A millilitre is equal to the volume of a cube with 1 cm on each side. As a result, one millilitre equals one cubic centimetre. There are 1000 mL in a litre, that is the same as 1000 cm3 in a square metre.
1 ml = 1 cm³
1000 ml = 1 liter
