The elements in the substance are mixtures of their isotopes.

The average atomic mass includes all of the isotopes of that atom which exist in nature. Almost all elements have at least two isotopes which naturally occur. 
Recall that isotopes are atoms with the same atomic number (protons), but a different number of neutrons. Since neutrons contribute the same amount of mass as a proton (1 amu), differing numbers of neutrons will change the mass of the atoms.

Which of the following conditions would speed up the rate of decomposition? (Select
Anna11 [10]

Answer:

E and B

Explanation:

the warmer the weather the faster it will decompose, this why is why sometimes bodies last longer frozen, or in cool temperatures.

that statement takes a out.

An illness shouldn't effect a decomposing body

Weight also shouldn't effect a decomposing body

Being buried can make bodies decompose fast because of all the bugs and other animals that will get down there and decompose it faster

Answer: B,E

use the heisenberg uncertainty principle to calculate the uncertainity in meters in the position of 0.68g and traveling at a vel
My name is Ann [436]

Answer:

7.7439×10⁻³¹ m

Explanation:

The expression for Heisenberg uncertainty principle is:

\Delta x\times \Delta v=\frac {h}{4\times \pi\times m}

Where m is the mass of the microscopic particle

h is the Planks constant

Δx is the uncertainty in the position

Δv is the uncertainty in the velocity

Given:

mass = 0.68 g = 0.68×10⁻³ kg

Δv = 0.1 m/s

Δx= ?

Applying the above formula as:

\Delta x\times 0.1=\frac {6.62\times 10^{-34}}{4\times \frac {22}{7}\times 0.68\times 10^{-3}}

<u>Δx = 7.7439×10⁻³¹ m</u>
