Answer:
12 Neutrons
Explanation:
So the mass of sodium is 22.990. You round it up to get 23(as stated in the problem). So, <em>what exactly is atomic mass?</em>
Atomic Mass is the total amount of neutrons and protons added up to form a total mass. So when you subtract 23-11 you get 12 Neutrons.
<u>Tip: </u>Don't know if you need this but-
The neutrons and protons are typically close in number (unless it's an isotope). So say that you subtract and the numbers of protons and neutrons aren't close at all. Well if that's the case, it's probably wrong.
hope this helps!!
Given: Universal Gravitational constant = G = 6.67 x 10⁻¹¹ N m²/Kg²
Mass₁ = 70 Kg; Mass₂ = 70 Kg Radius r = 1.5 m; Force F = ?
Formula: F = Gm₁m₂/r²
F = (6.67 x 10⁻¹¹ N m²/Kg²)(70 Kg)(70 Kg)/(1.5 m)²
F = 1.45 X 10⁻⁷ N
Answer:
c is correct
Explanation:
Steel is a metal that is made from iron and carbon. During the steel making process, iron & carbon are melted together, and is allowed to harden into a solid. The iron and the carbon DO NOT chemically react with each other. After the steel was made, 20 samples were taken from one piece and tested. Each sample contained 98% iron and 2% carbon.
Which of the following terms BEST describes steel? homogeneous mixture
An electron absorbs energy and emits electromagnetic radiation based on its transition.
<h3>What is an Electron?</h3>
This is defined as a sub-atomic particle which has a negative charge. It's involved in a chemical reaction which results in the formation of new substances.
Classical physics predicted that at a high enough temperature, ultraviolet light would be emitted. instead white light was emitted resulting in the ultraviolet radiation.
