Could’ve reacted with water as alkali metals are very reactive to water.
Nickel (Ni) has the charge as +3 while oxygen (O) has -2. Hence, the chemical formula for the nickel (iii) oxide is Ni₂O₃.
molar mass of Ni = 58.69 g/mol
molar mass of O = <span>15.99 g/mol
number of Ni atoms in </span>Ni₂O₃ = 2
Molar mass of Ni in Ni₂O₃ = 2 x 58.69 g/mol = 117.38 g/mol
number of O atoms in Ni₂O₃ = 3
Molar mass of O in Ni₂O₃ = 3 x 15.99 g/mol = 47.97 g/mol
Hence, molar mass of compound = 117.38 g/mol + 47.97 g/mol
= 165.35 g/mol
=<span> 165.4 g/mol</span>
For many (but not all) problems, you can simply round the atomic weights and the molar mass to the nearest 0.1 g/mole. HOWEVER, make sure that you use at least as many significant figures in your molar mass as the measurement with the fewest significant figures. In other words, never let your molar mass be the measured value that determines how many signficant figures to use in your answer!
Answer:
This combination product contains 2 medications, acetaminophen and an antihistamine. Acetaminophen helps to reduce fever and/or mild to moderate pain (such as headache, backache, aches/pains due to muscle strain, cold, or flu).

Because all the compounds are at the same concentration, the one that can produce more particles in solution will be the one that will raise the boiling point the most.
