Answer:
58.32
Explanation:
The mass number is one mole and for Mg it is 24.306 for O it is 15.999 and for H it is 1.008. because O and H have 2, you multiply them by 2 and add all the numbers and it equals 58.32
Answer is: no, <span>potassium iodide has low solubility in cyclohexane.
</span>Potassium iodide (KI) is ionic compound, salt, that dissolve good in polar solvents (for example water), but it is very low soluble in non-polar solvents (in this example cyclohexane C₆H₁₂).
<span>Cyclohexane has zero net polarity, because it is a symmetric molecule, with sp2 hybridization of carbon.</span>
Divide 180kg and 90m3 and your density will be 2kg/m3
<u>Answer:</u> The correct option is C) decomposition
<u>Explanation:</u>
Single displacement reaction is defined as the reaction where a more reactive element displaces a less reactive element from its salt solution.

Element B is more reactive than element A
Double displacement reaction is defined as the reaction where an exchange of ions takes place in a solution

Decomposition reaction is defined as the reaction where a single large chemical species breaks down into two or more smaller chemical species.

Synthesis reaction is defined as the reaction where two or more smaller chemical species combine together in their elemental state to form a single large chemical species.

For the given chemical reaction:

Here, water is breaking down into two smaller species of oxygen and hydrogen gas. Thus, it is a decomposition reaction.
Hence, the correct option is C) decomposition
Answer:
B. The electronegativities of the two atoms are equal.
