Answer: The correct option is A.
Explanation: In a chemical reaction, reactants react to form a number of products.
For the formation of products, the bonds of the individual reactants must be broken and the bonds of the products must be formed.
For example: Formation of water from hydrogen gas and oxygen gas. Reaction follows:
The Bonds of hydrogen and oxygen molecule are broken and new bonds between hydrogen and oxygen atoms are formed to give water molecule.
Answer:
Rate of appearance of Bromine is 2.04 X 10-4 M·s−1
Explanation:
According to the balanced stoichiometric equation, for every 5 moles of Br- that react, 3 moles of Br2 is produced so they have the stoichiometric ratio of 5:3.
We can use this to calculate the rate of appearance of bromine since this is a direct relationship.
Br- : Br2
5 : 3
3.4 ✕ 10−4 M·s−1 : x
5x = 1.02 X 10-3 M·s−1
x = 2.04 X 10-4 M·s−1
Aluminum because it’s a conductor, glass is more so of an insulator.
Can't say i can answer this. :/
Na-24 and Na-23 have the same number of atoms=11, different neutrons(13 and 12),different mass number(24 and 23)
<h3>Further explanation
</h3>
The elements in nature have several types of isotopes
Isotopes have the same number of protons and having a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
number of atoms = 11
mass number = 23
number of neutrons=23-11=12
number of atoms = 11
mass number = 24
number of neutrons=24-11=13
