This is sulfer, sulfer is the atom with 16 protons, neutrons and electrons.
It is 50 or 50% mass and air . Average Stone weight in Earth.
Answer:
Isotopes are atoms of the same element with the same number of protons but different number of neutrons.
Hope this helps.
The mass and speed/velocity determines the kinetic energy an object has.
Answer:
Magnesium chloride (MgCl₂) > Potassium bromide (KBr) > Butanoic acid (C₃H₇COOH) > Sugar (C₆H₁₂O₆) (Conductivity)
Explanation:
The given samples:
<u>Magnesium chloride (MgCl₂):</u>
It is a strong salt which dissociates 100% into 3 ions, 1 Mg²⁺ and 2 Cl⁻
<u>Sugar (C₆H₁₂O₆):</u>
It is a carbohydrate and will have 0% dissociation and thus, no ions.
<u>Butanoic acid (C₃H₇COOH):</u>
It is a carboxylic acid (weak acids) which partially dissociates.
<u>Potassium bromide (KBr):</u>
It is a strong salt which dissociates 100% into 2 ions, K⁺ and Br⁻.
Thus, Conductivity is directly proportional to the numbers of ions dissociated in the solution and hence will conduct more electricity.
So,
<u>Magnesium chloride (MgCl₂) > Potassium bromide (KBr) > Butanoic acid (C₃H₇COOH) > Sugar (C₆H₁₂O₆) (Conductivity)</u>
