gamma rays have an approximate wavelength of 1.0x10^-13 meters. what is the approximate energy of a gamma-ray?
Bogdan [553]

Answer:

E = 19.89 × 10⁻¹³ J

Explanation:

Given data:

Wavelength of gamma ray= 1.0× 10⁻¹³ m

Energy of gamma ray = ?

Solution:

Formula:

E = h c/λ

h = plancks constant  = 6.63× 10⁻³⁴ js

c = speed of light = 3 ×10⁸ m/s

by putting values,

E = 6.63× 10⁻³⁴ js × 3 ×10⁸ m/s /1.0× 10⁻¹³ m

E = 19.89 × 10⁻²⁶ J.m/ 1.0× 10⁻¹³ m

E = 19.89 × 10⁻¹³ J

Give the name and formula for the acid derived from each of the following anions:<br> (c) bromite
Travka [436]

The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.

<h3>What is Acids ? </h3>

Acids is defined as substances that is able to donate a proton or hydrogen ion to other substance. Acids acts as proton donor.

<h3>What is Oxoacids ? </h3>

An oxoacids is an acids that contains oxygen. It is also called oxyacids or ternary acids. Oxoacids are the acids of oxoanions.

If anion name contains the suffix ‘ate’ then replace ‘ate’ with ‘ic’.

If anion name contains the suffix ‘ite’ then replace ‘ite’ with ‘ous’.

Given anion is bromite. Formula of bromite is BrO₂⁻. It is an oxoanion.

Now write the name of acid. Here anion name contains the suffix ite so replace the ‘ite’ of bromite with ‘ous’.

The name of the acid is Bromous acid.   

Formula of the acid is HBrO₂.

Thus from the above conclusion we can say that The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.
