Answer:
The formation of magnesium carbonate in the form of a precipitate and sodium sulfate as a byproduct takes place.
Explanation:
When a drop of sodium carbonate is mixed with the magnesium sulfate, the formation of MgCO3, magnesium carbonate as a precipitate, and Na2SO4, sodium sulfate as a byproduct takes place. One can separate magnesium carbonate from the sodium sulfate by using the process of filtration. The chemical reaction that takes place in the process is:
MgSO4 (aq) + Na2SO4 (aq) ⇒ MgCO3 (s) + Na2SO4 (aq)
A separation process in which the formation of solid takes place in a solution after undergoing a chemical reaction is termed as precipitation. The precipitate is the name given to the solid substance that gets produced in the reaction. The precipitate formed can be withdrawn from the solution with the help of a physical separation procedure like filtration.
The answer would be either b or c because they are both correct
Answer:
The gas was N₂
Explanation:
V = 3.6L
P = 2.0 atm
T = 24.0°C = 297K
R = 0.0821 L.atm/K.mol
m = 8.3g
M = molar mass = ?
Using ideal gas equation;
PV = nRT
n = no. Of moles = mass / molar mass
n = m/M
PV = m/M * RT
M = mRT / PV
M = (8.3*0.0821*297) / (2.0*3.6)
M = 28.10
Since X is a diatomic molecule
M = 28.10 / 2 = 14.05 g/mol
M = Nitrogen
X = N₂
The precaution to be taken while measuring the temperature of a liquid in a beaker is applying proper heat balance and taking all the required precautions.
- A beaker with an open top contains a sample of liquid. It exposes this sample to light.
- That liquid absorbs the light energy, turning it into heat energy. As a result, the liquid becomes warmer and evaporation is accelerated. As a result, there is less liquid in the beaker.
- Since it is well known that the surface temperature of a liquid, along with air movement above the liquid surface, is one of the dominant factors affecting evaporation, I want to measure the evaporation rate as a function of surface temperature.
- This can be done by applying a heat balance.
