Could a 3 ion of aluminum be made by adding three protons to an aluminum atom

1 answer:

7 0

Protons cannot be so easily added to an atom, so this method cannot be used to produce ions. Protons are found in the nucleus which is held together by strong forces. This means that its structure is not easily changed. Bombarding it with a proton may even cause its decay, just as in nuclear fission a nucleus is bombarded with neutrons.

A microwave can have a frequency of 3.8 X 1010Hz. How much energy does this microwave give off in joules?

Marina86 [1]

Answer:

2.52 x $10^{-23}$ J

Explanation:

The energy given off by the microwave can be determined by the application of Planck's energy formula:

E = hf

where: E is the required energy, h is Planck's constant (6.626 x $10^{-34}$ $m^{2}$ Kg/s), and f is the frequency (3.8 x $10^{10}$ Hz).

So that;

E = 6.626 x $10^{-34}$ x 3.8 x $10^{10}$

= 2.51788 x $10^{-23}$

Therefore, the energy released by the wave is 2.52 x $10^{-23}$ J.

1. Which of the following is NOT a cation?

Bezzdna [24]

Hey Madoudou

The correct answer is option B (sulfate)

The reason is because "Sulfate" has a negative sign.

In order for it to be a cation, it must have positive sign such as "iron(lll)ion
