The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Therefore, we group elements whose atoms have the same number of valence electrons together in the Periodic Table. ... This tendency is called the octet rule, because the bonded atoms share eight valence electrons.
Chemical- it produces ammonia.
Answer:
Explanation:
You can identify an unknown substance by measuring its density and comparing your result to a list of known densities. Density = mass/volume. Assume that you have to identify an unknown metal.
Answer:
32/21
Explanation:
Find the GCD (or HCF) of numerator and denominator. GCD of 32 and 21 is 1.
32 ÷ 121 ÷ 1.
Reduced fraction: 3221. Therefore, 32/21 simplified to lowest terms is 32/21.
<u>Answer:</u> The energy released in the given nuclear reaction is 94.99 MeV.
<u>Explanation:</u>
For the given nuclear reaction:
We are given:
Mass of 
= 235.043924 u
Mass of 
= 1.008665 u
Mass of 
= 130.9061246 u
Mass of 
= 88.9058483 u u
To calculate the mass defect, we use the equation:
Putting values in above equation, we get:
To calculate the energy released, we use the equation:
(Conversion factor: 
)
Hence, the energy released in the given nuclear reaction is 94.99 MeV.
