The freezing point depression is calculated through the equation,
ΔT = (kf) x m
where ΔT is the difference in temperature, kf is the freezing point depression constant (1.86°C/m), and m is the molality. Substituting the known values,
5.88 = (1.86)(m)
m is equal to 3.16m
Recall that molality is calculated through the equation,
molality = number of mols / kg of solvent
number of mols = (3.16)(1.25) = 3.95 moles
Then, we multiply the calculated amount in moles with the molar mass of ethylene glycol and the answer would be 244.9 g.
Answer:
So if this is about chemical equations. You have 3 steps.
Step 1.- Count each type of atom in reactants and products.
Step 2.- Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.
Step 3.-Repeat steps 1 and 2 until the equation is balanced.

Answer:
Gas liquid solid
Explanation:
gases have a weak potential since they have a weak bond between molecules while in solids it's the strongest making them vibrate in a fixed position
Answer: how many industries and factories are in 'x' country.
Explanation: the main causes of global temperature rising are factories because, harmful gases can be released. And if the number of the factories increase the percentage of the harmful gas that is being released also increases. So to clarify evidence you can ask :- how many factories does country 'x' have?
By the way 'x' means any one country.
Hydrogen gas
Acid + metal = salt and hydrogen gas
