Answer:
B is correct answer because The enthalpy is negative so this means the reaction produces heat and the reaction is exothermic
Answer:
Oxygen in heavy water, or d20, have an extra neutron, and it contains a higher portion of hydrogen. The extra neutron makes d20 (heavy water) about 10% denser than normal H20 (water).
Hope this helps!

Hey there!
Atomic mass Bromine ( Br ) = 79.9 u
Therefore:
79.9 g Br --------------- 22.4 L ( at STP )
18.0 g Br --------------- volume ??
Volume Br = 18.0 * 22.4 / 79.9
Volume Br = 403.2 / 79.9
Volume Br = 5.046 L
hope this helps!
Answer:
E. The number of moles of solute in both solutions is the same.
Explanation:
The dilution of a solution consist in increase the volume of solution decreasing, thus, the concentration of the solution. The moles of solute doesn't change in a dilution process.
Thus, when a solution is diluted, the relationship of the number of moles of solute in the more concentrated initial volume of solution to the number of moles of solute in the less concentrated final volume of solution is that:
E. The number of moles of solute in both solutions is the same. TRUE.
I hope it helps!
its density should stay the same as it is a characteristic property and nothing was added sooo
