Answer:
centrifugation
Explanation:
Well the process centrifugation is used for separation of cream from curd.Well the force rotates it and the heavy and light particles are separated.Ij this way we can separate this mixture.
Hope it helps you.
<u>Answer:</u> The bronsted acids for the given reaction are
<u>Explanation:</u>
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses or donates protons and thus forming conjugate base.
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
For the given chemical equation:
For the forward reaction, looses 1 proton to form and thus acts as bronsted acid.
For the backward reaction, looses 1 proton to form and thus acts as bronsted acid
Hence, the bronsted acids for the given reaction are
Answer:
8.18 M
Explanation:
The osmotic pressure (π) is a colligative property that can be calculated using the following expression.
π = M . R . T
where,
M: molarity
R: ideal gas constant
T: absolute temperature
The absolute temperature is 25 + 273 = 298 K.
The osmotic pressure (in atm) is:
π = M . R . T
200 atm = M . (0.08206 atm.L/mol.K) . 298 K
M = 8.18 mol/L
34g C * ( 1 mol / 12.0107 ) * ( 1 mol H2 / 1 mol C ) * ( <span>2.01588 g / 1 mol H2 ) = 5.70657164028741 g H2 = 5.7 g H2
Convert grams of C to moles of C using the given amount of grams and the molar mass ( 12.0107 g/mol ).
Gather the mole ratio from the coefficients in the balanced equation and multiply by the ratio.
Convert moles of H2 to grams of H2 </span> using the given amount of grams and the molar mass ( 2.01588 g/mol )<span>.

Answer:
33 g of H2
Explanation:
N2 + 3 H2 -> 2 NH3
3 mol H2 -> 2 mol NH3
x -> 11 mol NH3
x= (11 mol NH3 * 3 mol H2)/ 2 mol NH3
x= 16.5 mol H2
1 mol H2 -> 2 g
16.5 mol H2 ->x
x= (16.5 mol H2 * 2 g)/ 1 mol H2
x= 33 g
