In water, hydrogen bonds are best described as _____.

Elina [12.6K]

Answer: Option D) covalent bonds between water molecules

In water, hydrogen bonds are best described as covalent bonds between water molecules

Explanation:

The hydrogen bonds between water molecules are covalent bonds because they are formed when oxygen attract the lone electron in hydrogen, thus resulting in the formation of a partially negative charge on the oxygen atom and a partially positive charge on two hydrogen atoms

Thus, the sharing of electrons between oxygen and hydrogen atoms is responsible for the covalent bonds between water molecules

1. Lanthanides and actinides are kept separately in the modern periodic table. Why?

AleksAgata [21]

Answer:

1.. Lanthanides and actinides are kept separately in the modern periodic table Why?

Lanthanides and actinides are kept separately in the modern periodic table because of following reason:

If they are placed in the body of the periodic table, the periodic table will become extremely long and hard to recognize
more scientific and technical reason why they chose to keep the lanthanides and actinides away from the rest of the periodic table was to help in the grouping of elements in blocks

Explanation:

2. Differentiate between long period and short period in any two points.

Long period:

The 4th and 5th periods of the periodic table are called long periods.
The long periods coontain 18 elements in them

short period:

The 2nd and 3rd periods of the periodic table are called short periods.
The short periods contain 8 elements in them

A total of 2.00 mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 107 g of solutio

AveGali [126]

Explanation:

The given data is as follows.

mass (m) = 107 g,

$\Delta T$ = $(24.70 - 21.00)^{o}C = 3.7^{o}C$

Specific heat of water = 4.18 $J/g^{o}C$

Since, the relation between heat energy, mass and temperature change is as follows.

q = $mC \Delta T$

Hence, putting the given values into the above formula to calculate the heat energy as follows.

q = $mC \Delta T$

= $107 g \times 4.18 J/g^{o}C \times 3.7^{o}C$

= 1654.86 J

Therefore, calculate the enthalpy of this reaction for 2.00 mol of a compound as follows.

$\frac{1654.86 J}{2.00 mol}$

= 827.43 J/mol

or, = $827.43 \times \frac{1 kJ}{1000 J}$ (as 1 kJ = 1000 J)

= 0.827 kJ/mol

Therefore, we can conclude that enthalpy of this reaction is 0.827 kJ/mol.

Calculate the freezing point of a solution made from 52.6 g of propane, c3H8, dissolved in 196.0 g of benzene, C6H6. The freezin

OLga [1]

Given: weight of solute (propane) = 52.6 g
weight of solvent (benzene) = 196 g = 0.196 kg
We know that, molecular weight of propane = 44.1 g/mol

∴ Molality of solution = $\frac{\text{weight of solute (g)}}{\text{Molecular weight X Weight of solvent (Kg)}}$
= $\frac{52.6}{44.1X.196}$ = 6.085 m

Now, Depression of freezing point = Kf m
where Kf = cryoscopic constant = <span>5.12 oC/m

</span>∴ Depression of freezing point = 5.12 X 6.085
= 31.15 oC

Therefore, freezing point of solution = 5.50 - 31.15 = -25.65 oC
