Answer:

In molecular geometry, bond length or bond distance is defined as the average distance between nuclei of two bonded atoms in a molecule.

Explanation:

It is a transferable property of a bond between atoms of fixed types, relatively independent of the rest of the molecule.

Predict whether each of the following reactions will occur in aqueous solutions. Explain your reasoning in each case. Note: Bari

tino4ka555 [31]

(a) sodium hydroxide + ammonium sulfate --> sodium sulfate + ammonium hydroxide

sodium sulfate precipitates in aqueous solutions

(b)<span> niobium(V) sulfate + barium nitrate → Barium sulfate + niobium nitride

both do not precipitate in aqueous solution

</span>(c) strontium bromide + silver nitrate ---> strontium nitrate + silver bromide

both do not precipitate in aqueous solution

The Henry's law constant (kH) for O2 in water at 20°C is 1.28e-3 mol/l atm. How many grams of O2 will dissolve in 3.5 L of H2O t

Sophie [7]

Answer : The mass of $O_2$ dissolved will be, 0.2365 grams

Explanation :

First we have to calculate the concentration of $O_2$ .

As we know that,

$C_{O_2}=k_H\times p_{O_2}$

where,

$C_{O_2}$ = concentration of $O_2$ = ?

$p_{O_2}$ = partial pressure of $O_2$ = 1.65 atm

$k_H$ = Henry's law constant = $1.28\times 10^{-3}mole/L.atm$

Now put all the given values in the above formula, we get:

$C_{O_2}=(1.28\times 10^{-3}mole/L.atm)\times (1.65atm)$

$C_{O_2}=2.112\times 10^{-3}mole/L$

The concentration of $O_2$ = $2.112\times 10^{-3}mole/L$

Now we have to calculate the moles of $O_2$

$\text{Moles of }O_2=\text{Concentration of }O_2\times \text{volume of solution}$

$\text{Moles of }O_2=(2.112\times 10^{-3}mole/L)\times (3.5L)=7.392\times 10^{-3}mole$

Now we have to calculate the mass of $O_2$

$\text{Mass of }O_2=\text{Moles of }O_2\times \text{Molar mass of }O_2$

$\text{Mass of }O_2=(7.392\times 10^{-3}mole)\times (32g/mole)=0.2365g$

Therefore, the mass of $O_2$ dissolved will be, 0.2365 grams

During the cold winter months the surface Of a lake becomes hard Ice this is due to which change of state

nikitadnepr [17]

Freezing

Explanation:

This change in state when surface of a lake changes to hard ice is known as freezing.

When a solid is heated, it melts and changes to a liquid. On further heating, it changes to vapor and the randomness increases.
When a liquid is cooled below its freezing point, it changes to a solid such as ice for water.
The phase change is known as freezing.
