Write a nuclear reaction for the neutron-induced fission of u?235 to produce te?137 and zr?97. how many neutrons are produced in
alexandr1967 [171]
This is a neutron induced fission, therefore a neutron will be added to the U²³⁵ to cause the reaction, and thus it will be added to the left side. There will be unknown number of neutrons produced and thus we put this on the right hand side.
n₁ + U²³⁵ = Te¹³⁷ + Zr ⁹⁷ + xn1 ( n1 to mean a neutron of mass 1)
To balance the masses on both sides of the equation;
1 + 235 = 137 +97+ x
x = 2 
the end reaction will be
n₁ +U²³⁵ = Te¹³⁷ + Zr⁹⁷ + 2 n₁

1. It has been suggested that pain results from a change in the pH of solutions that surround nerves in the body.
Akimi4 [234]

Answer:

See Explanation

Explanation:

According to the question, it is established that the pain caused by a lot of insect bites owes to the acidity of the insect bites.

If this is true, then there is an urgent need to neutralize the acidic insect bite using a basic substance.

Hence the pH of the creams used to treat insect bites should be basic(having a high pH).

2. The compound methene can not exist because it is supposed to be derived from the alkane called methane which contains only one carbon atom.

In order to form an alkene, there must be a double bond between two carbon atoms. This is not possible because there is only one carbon atom in the hypothetical methene. Hence,  a compound named methene cannot exist.
