Answer:

hii there

Explanation:

Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes.

Hope it helps

have a nice day

What begins to happen to radioactive uranium as soon as a mineral containing it crystallizes from magma?
Aleonysh [2.5K]
<span>The radioactive uranium decays into its daughter product, lead. It would do this in magma as well, as nuclear decay depends on forces within the atom, not on the phase of the material in which the atom is a part.</span>

Nitrogen monoxide and oxygen, both colorless gases, form a red-brown gas when mixed. Nitrogen monoxide and oxygen are called the
daser333 [38]

Answer:

Nitrogen monoxide and oxygen are called the reactants

Explanation:

Step 1: Given data

Nitrogen monoxide = NO

Oxygen = O2

Step 2: Balanced equation

2NO + O2 → 2NO2

This means that 2 moles of NO will be consumed and and 1 mole of O2 to produce 2 moles of NO2

This means NO2 is the prodcut that is produced.

NO +O2 react with eachother, to form NO2

This means nitrogen monoxide (NO) and Oxygen (O2) are called the reactants.

A substance placed in a container has a fixed volume and takes up the shape of the container. In which state does this substance
Tems11 [23]
The substance should be in liquid state.

First, it takes up space in the container, which leads to that it shouldn't be a solid, because solid doesn't change its shape easily.

Second, it has a fixed volume, it's difficult to compress the substance, therefore it shouldn't be gas too, as gas can be compressed easily.

Therefore we're left with liquid. And both of these given properties fits the property of liquid.

Enter your answer in the provided box. The atomic masses of 63Cu (69.17 percent) and 65Cu (30.83 percent) are 62.94 and 64.93 am
dybincka [34]

<u>Answer:</u> The average atomic mass of copper is 63.55 amu.

<u>Explanation:</u>

Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

Formula used to calculate average atomic mass follows:

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

  • <u>For _{29}^{63}\textrm{Cu} isotope:</u>

Mass of _{29}^{63}\textrm{Cu} isotope = 62.94 amu

Percentage abundance of _{29}^{63}\textrm{Cu} = 69.17 %

Fractional abundance of _{29}^{63}\textrm{Cu} isotope = 0.6917

  • <u>For _{29}^{65}\textrm{Cu} isotope:</u>

Mass of _{29}^{65}\textrm{Cu} isotope = 64.93 amu

Percentage abundance of _{29}^{65}\textrm{Cu} = 30.83 %

Fractional abundance of _{29}^{65}\textrm{Cu} isotope = 0.3083

Putting values in equation 1, we get:

\text{Average atomic mass of Copper}=[(62.94\times 0.6917)+(64.93\times 0.3083)]\\\\\text{Average atomic mass of copper}=63.55amu

Hence, the average atomic mass of copper is 63.55 amu.
