i think the answer is zero (0) because there is question
Answer:
380g
Explanation:
Given parameters:
Number of moles of Fluorine = 20moles
Unknown:
Mass of Fluorine = ?
Solution:
The number of moles is the unit of quantifying the amount of particles in a substance.
So;
Mass of a substance = number of moles x molar mass
Molar mass of F = 19g/mol
Now;
Mass of F = 20 x 19 = 380g
No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical.
Answer:
it'a answer number 2
Explanation: you divide the mass by volume and 32.2 divided by 4 is 8.05
Answer:
Because the specific heat of the metal is less than the specific heat of water.
Explanation:
Hello, happy to help you today!
In this case, we need to analyze a property called "specific heat" which accounts for how much energy is required to increase or decrease the temperature of 1 g of the substance by 1 °C.
In this case, since the specific heat of water is about 4.184 J/g°C and the specific heat of metals in general is greater than zero, of course, but less than one, we can infer that for the same amount of energy, when they are in contact, more grams of metal will be cooled down to those of water heated up, because the specific heat of the metal is less than the specific heat of water.
Best regards!.
