How can i find nuclear charge and overall charge while only knowing the atomic mumber, number of protons and electrons?

Mazyrski [523]

Explanation:

An atom is made up of:

Protons which are the positively charged particles
Electrons are negatively charged
Neutrons carry no charges.

Atomic number is the number of protons in an atom.

To find the nuclear charge:

We use the effective nuclear charge formula:

Effective nuclear charge = Atomic number - number of shielding electrons(non-valence electrons)

The shielding electrons are the non-valence electrons in the inner orbitals.

For example:

Ne:

atomic number = 10

Effective nuclear charge = 10 - (2) = 8+

Number of non-valence electrons is 2

The effective nuclear charge is 8+

Overall charge:

Charge = number of protons - number of electrons

For neutral atoms, the overall charge is zero as the number of protons and electrons are the same.

a 5.00 l air sample has a pressure of 107 kpa at a temperature of -50.0 C. if the temperature is raised to 102 C and the volume

Murljashka [212]

You have to use the combined gas law (P₁V₁/T₁=P₂V₂/T₂) and solve for P₂ to get P₂=P₁V₁T₂/T₁V₂.

You need to convert all of the temperature values into terms of Kelvin so -50°C turns into 223K and 102°C turns to 375K. After you make that conversion you can just plug in all of the values into the idea gas law and you should get P₂=228.5kpa.

I hope this helps. Let me know if anything is unclear.

A mouse is placed in a sealed chamber with air at 769.0 torr. This chamber is equipped with enough solid KOH to absorb any CO2 a

Answer: The amount of oxygen gas consumed by mouse is 0.202 grams.

Explanation:

We are given:

Initial pressure of air = 769.0 torr

Final pressure of air = 717.1 torr

Pressure of oxygen = Pressure decreased = Initial pressure - Final pressure = (769.0 - 717.1) torr = 51.9 torr

To calculate the amount of oxygen gas consumed, we use the equation given by ideal gas which follows:
