A sample of gas occupies 20 mL at -109 degree C. What volume does the sample
occupy at 65 °C?

Answers

Answer: V2= 41.2mL

Explanation:

Givens:

* V1= 20ml

* T1 = -109 ⁰C --> K= ⁰C + 273.15 --> 164.15 K

* V2 = ??

* T2= 338.15 K

Use Charles law V1/T1 = V2/T2

Since we are looking for V2 we can rearrange the formula to

V2= (T2 x V1) /T1

V2= (338.15K x 20mL) / 164.15 K

V2= 41.2mL

NOTE:

Temperature should always be in K not in ⁰C or ⁰F

To convert from C to K use

*K= ⁰C + 273.15

Enter your C value in the ( ⁰C ) and you can get K

Answers

Metallic structure

Explanation:

They have a high melting point due to the strong forces of attraction between the positive ions (cations) and the delocalised electrons. Moreover, they conduct electricity due to the sea of delocalised electrons.

[Extra: It could be an ionic compound since they also have a high melting point, however they only conduct electricity in liquid or aqeouus state.]

A horticulturalist wants to produce geraniums with specific characteristics.

She knows that the trait of red flowers is governed by the allele R (RR and Rr) and the trait of white flowers is governed by the allele r(rr).

The horticulturalist crosses two geraniums from the F1 generation.

Look at the Punnett square to see this cross.

R r
R RR Rr
r Rr rr


Which ratio of red-to-white flowering plants would she expect to see in the phenotypes of the F2 generation?

all red

3 red : 1 white

1 red : 3 white

2 red : 2 white

Answers

Yo,

In Geranium plant life red vegetation is given by using the allele R this is dominant (so RR or Rr ) genotype will produce crimson plant life.

If we communicate approximately the connected punnet square which i took from the workout e book, you could see that there was a cross made among vegetation with heterozygous genotype for red flora.

P1: Rr X Rr

Gametes: R: r : R : r

F1: RR: Rr: Rr: rr

so there is three: 1 in F1 offspring for red to white plant life.

Now the query is set f2 technology, while we cross F1 generation suppose we do a move of Rr and rr from F1 generations allow us to see what takes place.

F1: Rr: rr

Gametes: R: r: r: R

F2 : Rr : rr: Rr: rr

Rr: purple flowers

rr: White flora:

So the ratio in F2 era might be 2 crimson : 2 white. Please see connected punnet squares (first one for query) and the second of F1 move for better know-how.

I'm hoping that this will benefit you, so from my assumption and study it'd be 2 crimson : 2 white, if this is indeed the one i'm thinking of since nothing else was provided, if not please correct me.

Theoretical yield - 4.0539 g

2)a) 41.257 g

b) 0.6857moles

c) 23 g

Explanation:

1)

Theoretical yield is the mass of the product that can obtain from the equation, it is not practical.

Theoretical yield:

Mr of SiO2 - 60

Moles of SiO2 - 2.339/60 = 0.03898 moles

Mr of SiF4 - 104

Mass of SiF4 - 0.03898 * 104 = 4.05392 g

2)

a)

mr of B2H6 - 28

Moles of B2H6 - 36.1/28 = 1.2893 moles

Mr of O2 - 32

Mass of O2 - 32 * 1.2893 = 41.257 g

b)

Moles of B2H6 - 19.2/28 = 0.6857 moles

Stoichiometry 1:1 ratio between B2H6 and H2O

So moles of H2O is 0.6857

c) moles of O2 - 2/24(r.t.p) = 0.083 moles

Mass of B2H6 - 0.083 * 28 = 2.3 g

In metallic bonding, the electrons are “surrendered” to a common pool and become shared by all the atoms in the solid metal. Metallic bonding is found in metals and their alloys. When the atoms give up their valence electrons, they form ions. These ions are held together by the electron cloud surrounding them.

How many atoms are in 80.45g of magnesium

Answers

Answer:

see below

Explanation:

1. 1 mol Mg = 24.31 g = 6.02 *10^23 atoms

     calculate the number of atomsin 80.45g Mg

         Numberof atoms = 6.02*10^23 Mg atoms / 24.31 g * 80.45 g

                                    = 1.99*10^24 atoms

2.1 mol C-12 = 12.01g = 6.02 * 10^23 atoms

    calculate the mass using

                                       = 12.01 g C / 6.02*10^23 atoms * 100 atoms

                                       = 1.99 * 10^-21 g

Answer:

1.9926 * 10 ^24 

Explanation:

Molar Mass - Use Periodic table!

M ( Mg ) = 24.31 g / mole

n = 80.45 g : 24.31 g/mole = 3.31 moles

N a ( Avogadro`s constant ) = 6.02 * 10 ^23

N = Na * n = 6.02 * 10 ^24 * 3.31 = 19.926 * 10 ^23

Fossil fuels like coal, oil and natural gas supply 80 percent of the world’s energy to warm homes, charge devices and power transportation. They are also the primary human source of greenhouse gas emissions. Stanford scientists broadly agree that curtailing our use of fossil fuels would have significant benefits like improving health and reducing the number and severity of natural disasters, but it’s not yet clear what can replace them.

Explanation:

Two protons and two neutrons are released as a result of this reaction. Superscript 222 subscript 86. Rn Right arrow superscript 218 subscript 84. Po ? Which particle is released? one alpha particle two beta particles one alpha and one beta particle one high-energy photon.

Answers

The particle released in the reaction has been an alpha particle. Thus, option A is correct.

The release of protons and neutrons in a reaction has been nuclear reactions. The reactions results in the change in the atomic mass of the atom, with the formation of new atom. The extra mass has been released in the form of energy.

The release from the given reaction has been:

[tex]\rm ^{222}_{66}Rn\;\rightarrow\;^{218}_{84}Po\;+\;^A_ZX[/tex]

Where, X has been the particles that has been released with the nuclear reaction. The superscript A has been the Mass of particle, and subscript Z has been the atomic number.

According to the law of conservation, the mass has been constant on both the product and the reactant side. Thus, the mass and atomic number of eliminated particles has been given as:

[tex]\rm 222=218+A\\A=222-218\\A=4[/tex]

The atomic mass of the particle has been 4.

[tex]\rm 86=84+Z\\Z=86-84\\Z=2[/tex]

The atomic number of the particle has been 2.

The element with atomic mass 4, and atomic number 2 has been the Helium particles, [tex]\rm ^4_2He[/tex]. It has been an alpha particle. Thus, the particle released in the reaction has been an alpha particle. Thus, option A is correct.
