Answer:
temperature of the reaction vessel
Explanation:
temperature of the reaction vessel
-0° freezing point ice or ice cream
Well you know that you have to balance out the equation to 0. So if I is -1 and Ca is +2 you know that I had to equal to -2. So you can do that by having two of them. So Ca=+2 and I2=-2 so CaI2 would equal 0 meaning that would be the correct answer. Hope that I explained that correct :)
Answer: 25.37055324733817mol
Approximately 25.371mol
Explanation: Number of moles of a substance is the mass of that substance containing the same amount of fundamental units, for instance atom in 12.0g of 12°C
Therefore:
Number of moles= mass/ molecular mass
Where mass of fluorine given= 482g
Standard Molecular mass of fluorine= 18.9984032g/mol
Substituting value in equation
Mole= 482g/18.9984032g/mol = 25.37055324733817mol
Approximately : 25.371mol
Upon a constant pressure (P), volume (V) of a gas will vary in direct proportion to changes in temperature (T). So V1/T1 = V2/T2
V2 = V1T2/T1 = (500)(300)/150
V2 = 150000/150 = 1000 mL
