One isotope of oxygen differs from another isotope of oxygen in *

Answers

Answer 1

Each isotope of Oxygen has a different number of neutrons

Further explanation

The elements in nature have several types of isotopes

Atomic mass is the average atomic mass of all its isotopes

Isotopes are atoms has the same number of protons but has a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Some of the isotopes of oxygen are:

[tex]\tt _8^{16}O,_8^{17}O,_8^{18}O[/tex]

Each isotope has 8 protons and 8 electrons but has a different number of neutrons

For O-16: number of neutrons = 16-8 = 8

For O-17: number of neutrons = 17-8 = 9

For O-18: number of neutrons = 18-8 = 10

At 303 K, the volume of a gas is 30.0 ml. At constant pressure, what is the new
volume of the gas if the temperature is decreased to 283K?

Answers

Answer:

V₂ = 28 mL

Explanation:

Given data:

Initial temperature = 303 K

Initial volume = 30.0 mL

Final temperature = 283 K

Final volume = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 30.0 mL × 283 K /303 K

V₂ = 8490 mL.K / 303 K

V₂ = 28 mL

The force of attraction between one polar molecule and another polar molecule is​

Answers

Answer:

Dipole-dipole forces

Explanation:

A polar compound is that compound which contains atoms that have a difference in charges i.e electrostatic attraction occurs between its constituent atoms. Polar molecules are attracted to other polar molecules with opposite charges and her held together with the aid of certain forces

The attractive force between the negative part of a polar molecule (-) and the positive part of another polar molecule (+) is called DIPOLE-DIPOLE FORCES. This dipole-dipole force gets stronger with an increasing polarity of the molecules involved.

How many liters of ammonia are formed with 49.8 g of nitrogen gas reacting with 10.7 g of hydrogen gas at S.T.P.?

Answers

the reaction is as follows:

N2+3H2---->2NH3

the number of moles of N2 is 49.8g/14gmol^-1=3.56mol

the number of moles of H2 is 10.7g/2gmol^-1=5.35mol

here, since the ratio of N2/H2 is 1/3, we can see that H2 is the limiting reagent. therefore, the reaction proceeds as follows:

N2 + 3H2 ---------------> 2NH3
5.36mol (2/3)(5.36mol)=3.57mol

therefore, the number of moles of ammonia formed is 3.57mol. at STP, P=1atm, T=273K.
Therefore, V(NH3)=(3.57)(22.38)=79.822 L

Write the net ionic equation for the following reaction:

Explanation:

The net ionic equation reflects the main reaction that occurred in the system. It tells you the most important reaction that took place.

If we first put down the balanced molecular equation for the reaction, we have;

CaCl2(aq) + 2 AgC2H3O2(aq) ---------> 2 AgCl(s) + Ca(C2H3O2)2 (aq)

The net ionic equation is;

2Ag^+(aq) + 2Cl^-(aq) --------> 2AgCl(s)

Which element wants to gain valence electrons while bonding?
a. Neon (Ne)

b. Fluorine (FI)

c. Lithium (Li)

d. Magnesium (Mg)

Answers

Answer:

b. Fluorine (FI)

Explanation:

From the given choices, only fluorine wants to gain valence electrons while bonding.

This is because fluorine is the most electronegative specie from the given choices. An electronegative substance have a high tendency to attract electrons to itself in a bond.

Neon is a noble gas and it is stable. Lithium and Magnesium are metals that are electropositive. They prefer to lose electrons than to gain electrons.

How many moles are there in a 122 gram sample of nickel (Ni)?
7.16 x 103 moles
6.22 mol
2.08 mol
0.481 mol

Answers

the molecular weight of nickel is 58.69 g/mol. thus in a 122 gram sample of nickel there are 122/58.69=2.08 moles of nickel.

The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.

Nickel:

The atomic number of nickel is 28.The symbol of nickel is Ni.Density of a nickel 8.908 g/cm3.It is a d block element.It belongs to group 10 and period 4.It is also called transition metal.It is a metal and is located between groups 2 and 3.

Mass of nickel given: 122 grams.

Atomic mass of nickel: 58.71 g mol

Number of moles = Mass / molar mass

                             = 122/ 58.71

                              = 2.078

                              = 2.08 moles.

The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.

freons

Answers

Answer:

ions

Explanation:

Individual atoms of the same element but having slightly different number of protons and electrons are called ions.

Ion is a charged particle.

An atom is made up of three fundamental subatomic particles. Protons are the positively charged particles Electrons are the negatively charged particles Neutrons do not carry any charges.

When the number of protons > electrons the body is positively charged.

When the number of electrons > protons the body is negatively charged.

Charged particles are called ions.

What type of radioactive decay is shown? 82 Br → 82 Kr + te 35 36 Alpha O Beta O Gamma?​

Answers

Answer:

In 1889, Ernest Rutherford recognized and named two modes of radioactive decay, showing the occurrence of both processes in a decaying sample of natural uranium and its daughters. Rutherford named these types of radiation based on their penetrating power: heavier alpha and lighter beta radiation. Gamma rays, a third type of radiation, were discovered by P. Villard in 1900 but weren't recognized as electromagnetic radiation until 1914. Since gamma radiation is only the discharge of a high-energy photon from an over-excited nucleus, it does not change the identity of the atom from which it originates and therefore will not be discussed in depth here.

Because nuclear reactions involve the breaking of very powerful intra nuclear bonds, massive amounts of energy can be released. At such high energy levels, the matter can be converted directly to energy according to Einstein's famous Mass-Energy relationship E = mc2. The sum of mass and energy are conserved in nuclear decay. The free energy of any spontaneous reaction must be negative according to thermodynamics (ΔG < 0), and ΔG is essentially equal to the energy change ΔE of nuclear reactions because ΔE is so massive.
