Answer:
See below
Explanation:
A chemist preforms the following: Neutralizing nitric acid (HNO3) with soda ash (Na2CO3). This reaction will then create sodium nitrate and carbonic acid, which will then decompose into water (H20)
Answer:Nuclear binding energy is the energy needed to separate nuclear particles
The strong nuclear force holds an atom’s protons and neutrons together
Nuclear binding energy can be calculated using E=mc2
Explanation:
In evolutionary biology, a common ancestor is allegedly a link between two varying branches or types of creatures. (Another word for these is 'missing links', since up to this point, not a single one of these common ancestors has been found in the fossil record)
Hope that helped =)
Answer:
250J
Explanation:
Given parameters:
Spring constant = 500N/m
Extension = 1m
Unknown:
Elastic potential energy = ?
Solution:
The elastic potential energy of a body is the energy stored within an elastic string.
EPE = 
k e²
k is the spring constant
e is the extension
Now;
EPE = x 500 x 1² = 250J
It’s gas because the molecules are moving quicker.
