In what element will metallic bonding occur?

A 10L gas container is designed to hold gasses with a pressure of up to 5000mmHg. If a gas sample that has a pressure of 600mmHg

Morgarella [4.7K]

Explanation:

First, let's review the ideal gas law, PV = nRT. In this equation, 'P' is the pressure in atmospheres, 'V' is the volume in liters, 'n' is the number of particles in moles, 'T' is the temperature in Kelvin and 'R' is the ideal gas constant (0.0821 liter atmospheres per moles Kelvin).

The regulation of mineral ions in the cellular fluids of biological systems is performed by ion pumps that selectively transport

siniylev [52]

Answer:

The smallest ion is : Mg 2+

Increasing Order of size :

Mg2+ < Na+ < F- < O2-

Explanation:

Isoelectronic Species : Species having same number of electrons .

$Z_{eff}$ = Effective attraction of the nucleus felt by the outer shell electrons.

The size of the atom is decided by :

Its atomic number (number of proton)

the effective nuclear charge.

As the positive charge increases the size of the ion decreases.

As the negative charge increases the size of ion also increases.

Negative charged ions : F- , O2-

Negative charge are formed when electrons are added to the atoms.

When Negative ion is formed :

Number of proton remain same

Number of electron get increased

Hence it becomes difficult for the proton in the nucleus to attract the electrons.

Electron - electron Repulsion increases

$Z_{eff}$ = decreases

Size increase

Positive charged ions : Na+ , Mg2+

Positive charge are formed when electrons are removed from the atoms.

When Positive ion is formed :

Number of proton remain same

Number of electron get reduced

Hence more attraction of the nucleus is felt by the outer electron.

Electron - electron Repulsion Decreased

$Z_{eff}$ = increases

Size decreases

An engineer turns the temperature of a gas down, holding the volume constant at 1,250 L. Initially, the temperature of the gas w

Natalija [7]

Answer:

625=275

240=x

625x=275×240

625x=66000

x=66000/625

x=105 .6

Explanation:

If 625°C gives us 275KPa then 240°C will give us the the sum of 275×240 divided by 625

How do greenhouse gases affect temperatures on Earth?

Feliz [49]

=>. the function of greenhouse gases are

=>. it captures the heat comming out from the

sun

=>. by capturing the heat it makes our earth

warm

=> if excess of heat will traped by them then

our earth become more warm and this leads

to increase in temperature

=> when the overall temperature will increase

then the ice sheets on pole will melts

and this leads to increase in sea level

=> then the land near water will sinks in water
