Answer:
A) Cations
Explanation:
a) Cations have a positive charge and are larger than their neutral counterparts!
b) Anions have a negative charge and are smaller than their neutral counterparts
c) Metals can have either a positive or negative charge making it either a cation or an anion
d) Carbon is an element and it can have a charge anywhere from +4 to -4
A good way to remember that cations are positive is to think that CATions are always PAWSitive! ^-^
Answer:
0.823 M was the molarity of the KOH solution.
Explanation:
(Neutralization reaction)
To calculate the concentration of base , we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is KOH.
We are given:
Putting values in above equation, we get:
0.823 M was the molarity of the KOH solution.
A base and an Acid always react to form a salt and water
So, HCl + NaOH —> NaCl + HOH
The answer is c hopefully I helped you
Answer:
It's better to explain it.
Explanation:
Neutrons do not affect the electron configuration, but the sum of atomic number and the number of neutrons, or neutron number, is the mass of the nucleus. You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there. Neutron numbers are able to change the mass of atoms, because they weigh about as much as a proton and electron together. if your asking What is the role of a neutron in an atom? then, Neutrons are very important in providing stability for an atom. Some atoms don't "need" neutrons - The hydrogen atom does not have any neutrons. However, as the atomic number ( # of protons ) increases, the number of neutrons increases as well.
Protons don't like each other. Naturally, 'positive charges repel', so it wouldn't be possible to have more than one proton in the nucleus. Here's where the neutron comes in.
Hope this helps. :)
