Helium decays to form lithium.

Chemistry
1 answer:
hjlf3 years ago
7 0

Answer:

Natural nuclear disintegration.

Explanation:

This is because it cannot be managed, like it needs no energy particle yo occur, so its natural for helium to decay.

But it is nuclear because helium decays to release an energy particle (Beta particle).

An element consists of 5.85% of an isotope with mass 53.940 u, 91.75% of an isotope with mass 55.9349 u, 2.12% of an isotope wit
Gemiola [76]

Answer:

The answer to your question is: 55.84 u. The element is Iron

Explanation:

isotope 1    mass 53.94 u        abundance  5.85%

             2   mass 55.9349      abundance 91.75%

            3    mass 56.9354       abundance 2.12%

             4    mass 57.9333      abundance 0.28%

average atomic mass = (53.94 x 0.0585) + (55.9349 x 0.9175) + (56.9354 x 0.0212) + (57.9333 x 0.0028)

average atomic mass = 3.155 + 51.32 + 1.207 + 0.1622

average atomic mass = 55.84 u. The element is Iron

A sample of hydrogen gas exerts a pressure of 466 torr in a container. What is this pressure in atmospheres? (1 atmosphere = 1.0
Ulleksa [173]

Answer:

pressure = 0.61512atm

Explanation:

1 torr = 0.00132 atm

466 torr = unknown atm

unknown = 0.61512 atm

pressure = 0.61512atm

Consider a 12.01 g sample of carbon. the average mass of a carbon atom is 1.994 3 10223 g. how many carbon atoms are in the samp
Nonamiya [84]
 the mass of a carbon atom is 1.994 x 10⁻²³ g
the mass of the carbon sample is 12.01 g
to find the number of Carbon atoms we have to divide the mass of sample by mass of a carbon atom.
number of C atoms = \frac{12.01 g}{1.994* 10^{-23}g }
therefore number of atoms = 6.023 X 10²³ atoms of carbon

The property which primarily controls how much water can be present as a gas is:
Assoli18 [71]
The temperature of the air is the property which primarily controls how much water can be present as a gas. 

Meteorology is the study of the atmosphere. It primarily focuses on weather which is defined as the condition of the atmosphere at a certain time and place. It changes every day depending on earth location. There are five factors that affect weather namely, temperature, pressure, humidity, wind and precipitation.

The question above primarily talks about humidity-the amount of water vapor in the air. As the  temperature increases, the air or gas can hold more water. The warmer the air is, the more water it can possibly hold as vapor.

The reaction a(g)⇌2b(g) has an equilibrium constant of k = 0.030. what is the equilibrium constant for the reaction b(g)⇌12a(g)?
aalyn [17]
First, we have to correct the equation in the question to b(g)⇆ 1/2 A(g)
at the first equation A(g)⇆ 2 B(g) so,
 Kc = [B]^2 [ A] = 0.03 

by reverse the equation 2B⇆ A 
∴ Kc(original) = [A] / [B]^2

        = 1/0.03 = 33 M^-1

and the new equation B⇆ (1/2) A 
So, the new Kc = √Kc(original = √33 
                ∴    KC  = 5.7
