Answer:
Hydrogen.
Explanation:
The flammable gas it produces is hydrogen.
Diborane gas B2H6 and boric acid are also produced.
Answer:
The freezing point will be -2.046°C.
Explanation:
The freezing point depression equation is ![\Delta T_f = k_f \cdot m \cdot i](https://tex.z-dn.net/?f=%5CDelta%20T_f%20%3D%20k_f%20%5Ccdot%20m%20%5Ccdot%20i)
Where;
= The temperature depression of the freezing point
= The constant of freezing point depression which is solvent dependent = 1.86°C/m
i = The number of particles the substance decomposes into in solution = 1 for sugar (a covalent compound)
m = The molality of the solution = 1.1
Therefore, we have;
![\Delta T_f = 1.86 \times 1.1 \times 1 = 2.046 ^{\circ}C](https://tex.z-dn.net/?f=%5CDelta%20T_f%20%3D%201.86%20%5Ctimes%201.1%20%5Ctimes%201%20%3D%202.046%20%5E%7B%5Ccirc%7DC)
Therefore the freezing point will be 0 - 2.046°C = -2.046°C.
Answer:
A water molecule can react with the carbonyl group of an aldehyde or a ketone to form a substance known as a carbonyl hydrate, as shown in the first reaction below. The carbonyl hydrates usually form a very small percentage of the molecules in a sample of a specific aldehyde or ketone.
