I will assume the chemical reaction equation is like this:
<span>Ba(NO3)2 + Na2SO4 ---> 2 NaNO3 + BaSO4
</span>
For every 1 barium nitrate molecule used, there will be 1 barium sulfate formed. The number of molecule barium sulfate formed would be: <span>20.00 ml * 0.500 mol/1000ml * 1= 0.01 mol
The mass of barium sulfate produced: 0.01mol * </span>233.38 g/mol= 2.3338 grams
The correct answer is :
the purpose of heating the mixture is to accelerate the reaction and mix the reagent.
The explanation:
Many organic reactions are slow and can take an extended period of time to achieve any noticeable effect so heating is often used to increase the rate of reaction. However, many organic compounds have low boiling points and will vaporise upon exposure to such high heat, preventing the reaction from proceeding in full.
so, heating is used. This refers to heating a solution with an attached condenser to prevent reagents from escaping

Answer:
Molality = 66.67g/L
Explanation:
Mass of sucrose = 100g
Volume of water = 1.50L
Molality = mass of substance/ volume in L
Molality = 100 / 1.50
Molality = 66.67g/L
Molality of 100g of sucrose in 1.50L of water is 66.67g/L
I think It's a value that depends on another
