What is the vapor pressure of propanone
at 50°C?

Answers

Answer 1

Answer: If we work it out with direct proportions, the vapor pressure of propanone is 56 degrees Celsius. The atmospheric pressure is about 101.

Explanation: hope this helps.

Answer 2

The vapor pressure of propanone at 50°C is :

- 78° vapor pressure

Propanone

When the vapor pressure is specifically work through the extents to a temperature rate it response is intensely subordinate on their possess a mass nature.

The vapor weight of propanone is calculated and shape in degree Celsius in rate.

The rate of vapor when it is calculated by 50°C with propanone its at long last gives us a 78° vapor pressure.

What does these mean (thermal energy, convection, radiation and coundution)

Answers

Answer:

Thermal Energy: It refers to some distinct physical concepts, such as the internal energy of a system or heat or sensible heat. And these mode of transfer of heat include, convection, conduction and radiation which I have explained below.

Convection: This is a mode of transfer of heat in which bulk movement of molecules within fluids takes place, as these molecules move the heat obtained by each of the molecules will reach the new location.

Radiation: Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium

Conduction: Conduction is the transfer of internal energy by microscopic collisions of particles and the movement of electrons within an object.

Answers

Answer: 1.12 Liters

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given molecules}}{\text {avogadro's number}}=\frac{3.24\times 10^{22}}{6.023\times 10^{23}}=0.05moles[/tex]

1 mol of [tex]Cl_2[/tex] occupy = 22.4 L

Thus 0.05 mol of [tex]Cl_2[/tex] will occupy = [tex]\frac{22.4}{1}\times 0.05=1.12 L[/tex]

Balance this equation. Pb(NO3)2(aq)+NaCl(aq) -> NaNO3(aq)+PbCl2(s)

Answers

Answer:

Pb(NO3)2(aq) + 2NaCl(aq) -> 2NaNO3(aq)+PbCl2(s)

Explanation:

Pb(NO3)2(aq)+NaCl(aq) -> NaNO3(aq)+PbCl2(s)

This is how it starts out.

Left:

2 NO3s1 Pb1 Na1 Cl

Right

1 Na1 NO31 Pb2 Cl

So the place to start with this equation is to bring the Cls up to 2

Pb(NO3)2(aq)+2NaCl(aq) -> NaNO3(aq)+PbCl2(s)

But the Nas are now out of kilter.

Pb(NO3)2(aq)+ 2NaCl(aq) -> NaNO3(aq)+PbCl2(s)

Now the right has a problem. There's only 1 Na

Pb(NO3)2(aq) + 2 NaCl(aq) -> 2NaNO3(aq)+PbCl2(s)

Check it out. It looks like we are done.

The diagram shows a pedigree for a recessive inherited trait. If H represents the dominant allele and h represents the recessive allele what are the genptypes of the parents shown in the pedigree.

Answers

Answer:

Hh

Explanation:

if you have a dominant allele and a recessive allele they'd be different (heterozygous)

If H represents the dominant allele and h represents the recessive allele, Hh is the genotypes of the parents shown in the pedigree.

What is genotypes?

The type of variation present at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolize it. For illustration, BB, Bb, and bb might be employed to denote a certain gene variant.

The actual DNA sequence, such as CC, CT, or TT, can also serve as a representation of a genotype. In a single experiment, the genotypes spanning millions of sites in a genome can be determined using DNA sequencing as well as other techniques. If H represents the dominant allele and h represents the recessive allele, Hh is the  genotypes of the parents shown in the pedigree.

Therefore,  Hh is the  genotypes of the parents shown in the pedigree.

When magnesium is added to hydrochloric acid, a gas is formed. Explain what happens in the reaction, how the gas is collected and how it could be tested to prove what it is.

Answers

Answer:

Explained below.

Explanation:

Formula when magnesium reacts with hydrochloric acid is given by;

Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g)

So, from the equation, we can see that the gas formed is hydrogen.

This hydrogen gas is collected by a method known as water displacement.

This gas can be tested for by holding a burning splint near to the top of the test container. The resulting effect should be a high pitched pop sound because the hydrogen gas will react with the oxygen gas in the air to result in a small explosion.
