Answer : The correct option is, Hot water holds less dissolved oxygen than cold water.

Explanation :

As we know that the gases are more soluble in the liquids at the lower temperatures.

When the water heats up the average kinetic energy of the molecule increases. That means at the higher temperature the more number of molecules will escape or evaporate in atmosphere.

But at lower temperature the less number of molecules will escape or evaporate in atmosphere.

Hence, the hot water holds less dissolved oxygen than cold water.

The c—c—c bond angle in propane, c3h8, is closest to
Archy [21]
Propane has a molecular formula C3H8.

It is of the form CnH2n+2.
where n = number of C atoms. In present case n = 3.

Each carbon atom in propane is sp3 hydribized. Thus, there are 4 hydrid orbital associated with each carbon atom

The central C atom is sigma bonded to two other carbon atoms and two hydrogen atoms.

Such, sp3 hydridized orbitals are spacial orientated at an  angle of 109^{0}28^{'}, in order to minimize repulsion between the electrons.

Hence, the c—c—c bond angle in propane, c3h8, is closest to 109^{0}28^{'}

A sealed container has 1 mole of helium and 2 moles of nitrogen at 30DC when the total pressure of mixture is 0.60 atm what is t
bezimeni [28]

Answer:

The partial pressure of  nitrogen is  0.402 atm.

Explanation:

Given data:

Number of moles of helium = 1 mol

Number of moles of nitrogen = 2 mol

Total pressure of mixture = 0.60 atm

Partial pressure of nitrogen = ?

Solution:

First of all we will calculate the mole fraction of nitrogen.

mole fraction of nitrogen = moles of nitrogen / total number of moles

mole fraction of nitrogen = 2 mol / 3 mol = 0.67

Partial pressure of nitrogen:

P₁ = [ n₁ /n(t)] × Pt

P₁ = 0.67 × 0.60 atm

P₁ = 0.402 atm

1. Which of the following is an example of a chemical change?
bixtya [17]
B. A mixture of flour, sugar, eggs, and butter is baked to become a cake. Remember chemical change is when a substance combines with another to form a new substance. The answer wouldn't be A because the flour and sugar are mixing together, but they could be separated to their original forms. It wouldn't be C because the egg is only broken not chemically changed or formed with anything else. It wouldn't be D because the chocolate squares could be frozen or hardened to change it from icing. B is the best answer. Hope this helps! -sciencegeek338
