Answer:

[1] sulphur trioxide

Explanation:

Isoelectronic species have the same number of valence electrons.

Valence electrons in nitrate (NO₃⁻):

5e- (N) + (3 x 6e-)(3xO) + 1e- (charge) = 24e-

Valence electrons in sulphur trioxide (SO₃):

6e- (S) + (3 x 6e-)(3xO) = 24e-

Valence electrons in sulphite (SO₃²⁻):

6e- (S) + (3 x 6e-)(3xO) + 2e- (charge) = 26e-

Valence electrons in phosphine (PH₃):

5e- (P) + (3 x 1e-)(3xH) = 8e-

Valence electrons in water (H₂O):

6e- (O) + (2 x 1e-)(2xH) = 8e-

Valence electrons in chlorite (ClO₂⁻):

7e- (Cl⁻) + (2 x 6e-)(2xO) + 1e- (charge) = 20e-

The only species isoelectronic with nitrate is sulphur trioxide. Both have trigonal planar geoemetry.

If a gas is 16 times as heavy as hydrogen which will diffuse faster and by what ratio​
vodka [1.7K]

Answer:

1. Hydrogen will diffuse faster.

2. The ratio of diffusion of hydrogen gas to that of the unknown gas is 4 : 1

Explanation:

Let the rate of diffusion of hydrogen gas, H2 be R1

Let the molar mass of H2 be M1

Let the rate of diffusion of the unknown gas be R2.

Let the molar mass of the unknown gas be M2.

Molar mass of H2 (M1) = 2x1 =2g/mol

Molar mass of unknown gas (M2) = 16 times that of H2

= 16 x 2 = 32g/mol

1. Determination of the gas that will diffuse faster. This is illustrated below:

R1/R2 = √(M2/M1)

R1/R2 = √(32/2)

R1/R2 = √16

R1/R2 = 4

Cross multiply

R1 = 4R2

From the above calculations, we can see that the rate of diffusion H2 (R1) is four times the rate of diffusion of the unknown gas (R2).

Therefore, hydrogen will diffuse faster.

2. Again, from the calculations made above, the ratio of diffusion of hydrogen (R1) to that of the unknown gas (R2) is given by;

R1/R2 = 4

Therefore, the ratio of diffusion of hydrogen (R1) to that of the unknown gas (R2) is:

4 : 1

1. The basic building block of matter are atoms. Every atom is basically a tiny sphere. Every atom is composed of 2 regions, the
V125BC [204]

1. The answer is: Electron cloud.

Atom is composed of the nucleus and the electron cloud.

Protons (positive particles) and neutrons (neutral particles) are in the nucleus of an atom and electrons (negative particles) are in the electron cloud.

Nucleus is in the centar of the atom atom and electron cloud is surrounding it.

2. The answer is: Electron(s).

The electron (symbol: e⁻) is a subatomic particle whose electric charge is negative one elementary charge.

Metallic bond increace electrical and thermal conductivity.

Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons. Most metals have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.

3. The answer is: Nucleus.

Atomic number (Z) is total number of protons and mass number (A) is total number of protons and neutrons in a nucleus.

Nucleus of an atom has positive charge, electrons are negative and atom has neutral net charge.

For example, alpha particle is nucleus of a helium-4 atom, which is made of two protons (p⁺) and two neutrons (n°).

4. The answer is: Proton(s).

The proton (p⁺) is subatomic particle with a positive electric charge of +1e elementary charge.

Protons and neutrons, each with masses of approximately one atomic mass unit, are called nucleons.

Protons and neutrons are hadrons composed of three valence quarks.

The electron has a mass that is approximately 1/1836 that of the proton and the neutron.

5. The answer is: Neutron(s).

Neutron (symbol: n°) is a subatomic particle with no net electric charge.

Protons and neutrons are found in nucleus of an atom (atomic nuclei).  

They are called nucleons and have masses of approximately one atomic mass unit.

Mass number (A) is sum of protons and neutrons in nucleus of an atom.

6. The answer is: Direct relationship.

For example, the Hertzsprung–Russell diagram shows the relationship between the star's absolute luminosities (the total amount of energy emitted per unit of time by a star) versus their effective temperatures (the temperature of a black body that would emit the same total amount of electromagnetic radiation).

The Hertzsprung–Russell diagram puts each star on a graph according the star's brightness against its temperature.

7. The answer is: Inverse relationship.

For example, Wavelength is the inverse of the frequency.

Wavelength is the distance over which the wave's shape repeats.

The frequency is a measure of how often sinusoidal components of the wave repeat per unit of distance.  

Higher the frequency, shorter the wavelenght.

Shorter the frequncy, longer the wavelenght.

8. The answer is: No relationship.

Correlation is any statistical association, how close two variables are to having a linear relationship with each other.

If the correlation between the two variables is zero, there is no relationship

between them. So, variables have nothing to do with each other.

9. The answer is: Experimental control.

An experimental control is used in scientific experiments to minimize the effect of variables which are not the interest of the study.

The two main variables in an experiment are the independent and dependent variable.

Dependent variable is the variable being tested and measured in a scientific experiment.

Dependent variables depend on the values of independent variables. The dependent variables represent the output or outcome whose variation is being studied.

10. The answer is: Controlled variable(s).

A control variable is an experimental element which is constant and unchanged throughout the course of the experimentation.

For example, if the volume is made the control variable, it is not allowed to change it throughout the course of the experiment.

The control variables are not of primary interest to the experimenter.
