<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>
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.
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.
<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:
.....(1)
- <u>For
isotope:</u>
Mass of
isotope = 62.94 amu
Percentage abundance of
= 69.17 %
Fractional abundance of
isotope = 0.6917
- <u>For
isotope:</u>
Mass of
isotope = 64.93 amu
Percentage abundance of
= 30.83 %
Fractional abundance of
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](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20atomic%20mass%20of%20Copper%7D%3D%5B%2862.94%5Ctimes%200.6917%29%2B%2864.93%5Ctimes%200.3083%29%5D%5C%5C%5C%5C%5Ctext%7BAverage%20atomic%20mass%20of%20copper%7D%3D63.55amu)
Hence, the average atomic mass of copper is 63.55 amu.
