Answer: mixture
Explanation: they are heterogeneous mixtures not homogeneous
Answer:
the direction of the motion us constantly changing during motion over any close path, not only circular
25 kj absorbed by dissolving 1 mole of NH4NO3
1kj is absorbed by dissolving = 1/25.7 = 0.03891 moles
what about 73 kj absorbed by dissolving
0.03891 x73= 2.8404 moles
An Explanation -
Why Ice Floats. A substance floats if it is less dense, or has less mass per unit volume, than other components in a mixture. For example, if you toss a handful of rocks into a bucket of water, the rocks, which are dense compared to the water, will sink. The water, which is less dense than the rocks, will float.
Answer:
The compound with the correct formula is;
A. MNO₃
Explanation:
The number of oxidation states in the metal, M = One oxidation state
The formula of the compound formed by the metal, M = MHCO₃
We note that the ion HCO₃⁻, known as hydrogen carbonate has an oxidation number of -1
Similarly nitrate, NO₃⁻ has an oxidation number of -1, therefore, the metal M can form similar compound formed with HCO₃⁻ with nitrate, and we have;
The possible compounds formed by the metal 'M' includes MHCO₃ and MNO₃.
