Do you know the formula? I can’t find it.
37.8 g CH2Br2 X (1 mol CH2Br2 / 173.83 g) = 4.60X10^-3 mol CH2Br2
<span>4.60X10^-3 mol CH2Br2 X (2 mol Br / 1 mol CH2Br2) X 6.02X10^23 atoms/mol = 5.54X10^21 bromine atoms</span>
Answer: Region 3
Explanation: The temperature and time graph suggests that region 3 is the region in which the substance can co exist in both the phases that is solid phase and liquid phase.
Region 1 explains that the the solid has just started melting and there occurs a break point and then region 2 again explains that the solid is taking more time with temperature to get converted into the liquid and thus region 3 explains the equilibrium between the two phases.
Answer:
False
Explanation:
The mole ratio compares the coefficient of compounds reacting and giving products in a chemical reaction.
They are used for converting and showing relationship between reactants and products in a chemical reaction.
For example;
2A → B + C
the mole ratio is read as;
2 mole of A produces 1 mole of B and 1 mole of C
