Answer: Option (b) is the correct answer.

Explanation:

A beta particle is a particle with a negatively charged electron. Symbol of a beta particle is $^{0}_{-1}\beta$ .

An alpha particles is basically a helium nucleus and it contains 2 protons and 2 neutrons.

Symbol of an alpha particle is $^{4}_{2}\alpha$ .

A gamma particle is basically a photon of electromagnetic radiation with a short wavelength.

Symbol of a gamma particle is $^{0}_{0}\gamma$ .

Therefore, we can conclude that the charge of a beta particle is 1-.

6.0 L of gas in a piston at a pressure of 1.0 atm are compressed until the volume

alex41 [277]

Answer:

1.71atm

Explanation:

The following were obtained from the question:

V1 (initial volume) = 6L

P1 (initial pressure) = 1atm

V2 (final volume) = 3.5L

P2 (final pressure) =?

Using the Boyle's law equation:

P1V1 = P2V2, the final pressure can be obtained as follow:

P1V1 = P2V2

1 x 6 = P2 x 3.5

Divide both side by 3.5

P2 = 6/3.5

P2 = 1.71atm

The final i.e the new pressure inside the piston is 1.71atm

In an atom of an element there are a fixed number of electrons. If the total mass of electrons in 1 mole (6.022 x 1023) of atoms

prohojiy [21]

Answer:

No. of protons = 34

Explanation:

First we need to calculate the number of electrons in one mole of the the element:

No. of electrons per mole = Total Mass of Electrons/Mass of 1 Electron

No. of electrons per mole = (18.65 x 10⁻³ g)/(9.109 x 10⁻²⁸ g)

No. of electrons per mole = 2.04 x 10²⁵ electrons/mol

Now, we calculate the no. of electrons in 1 atom:

No. of electrons per atom = No. of Electrons per mole/No. of atoms per mole

No. of electrons per atom = (2.04 x 10²⁵ electrons/mol)/(6.022 x 10²³ atoms/mol)

No. of electrons per atom = 34 electrons/atom

Since, the no. of protons in a pure element are equal to the number of electrons. Therefore,

<u>No. of protons = 34</u>

On another planet, the isotopes of titanium have the given natural abundances. Isotope Abundance Mass (amu) 46Ti 72.000% 45.9526

tiny-mole [99]

Answer:

46.784886 amu is the average atomic mass of titanium on that planet.

Explanation:

Fractional abundance of Ti-46 =72.000% = 0.72000

Atomic mass of Ti-46 = 45.95263 amu

Fractional abundance of Ti-48 =14.300% = 0.14300

Atomic mass of Ti-48 = 47.94795 amu

Fractional abundance of Ti-50 =13.700% = 0.13700

Atomic mass of Ti-50 = 49.94479 amu

$\text{Average atomic mass }=\sum_{i=1}^n\text{(Fractional abundance)}_i\times \text{(Atomic mass of an isotopes})_i$

Average atomic mass of titanium atom:

$0.72000\times 45.95263 amu+0.14300\times 47.94795 amu+0.13700\times 49.94479 amu=46.784886 amu$

46.784886 amu is the average atomic mass of titanium on that planet.
