Explanation:
The question involves converting from one unit (Kilometres) to another unit (Astronomical unit)
The relationship between both units is given as;
1 Km = 6.68459e-9 Au
Kulper belt
6.5 billion km = 6.5e9 Km
1 Km = 6.68459e-9 Au
6.5e9 Km = x
Solving for x;
x = 43.45 Au
Alpha Centauri
44 trillion km = 4.4e13
1 Km = 6.68459e-9 Au
4.4e13 km = x
Solving for x;
x = 294121.83 Au
Answer:
Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance.
Explanation:
Answer: Option (A) is the correct answer.
Explanation:
A neutralization reaction is defined as the reaction in which an acid reacts with a base to yield salt and water.
The given reaction will be as follows.
Now, if molarity of NaOH =
and volume of NaOH =
Therefore, Molarity of HCl = molarity of
=
Volume of HCl required =
=
So, vVolume of
required = 0.5 x molarity of NaOH x \frac{\text{volume of NaOH}}{\text{molarity of H_{2}SO_{4}}}[/tex]
=
Hence, volume of HCl = 2 x volume of
.
Thus, we can conclude that HCl solution would be required more volume (in mL) to neutralize the base.
