Explanation:
MWQ means the minimum weighable quantity.
Mathematically, MWQ =
or, MWQ =
It is given that sensitivity is 4.5 mg and maximum permitted error is 3.6%.
Therefore, fraction error = = 0.036
Hence, we will calculate MWQ as follows.
MWQ =
=
= 125 mg
Thus, we can conclude that the MWQ of the given balance is 125 mg.

The international scientific units of measurements
<h3>
Explanation:</h3>
- SI units are units of measurement that are accepted and agreed upon globally as standard units of measurements.
- Examples include, meters(m) to measure length, kilograms(kg) to measure mass and seconds(s) to measure time among others.
- SI units can however, be converted to other units using multiplication factors. For example to convert kg to g we multiply the number of kg with 1000.
Answer:
C) The compound is largely ionic with A as the cation.
Explanation:
Pulings proposed the method to determine if the compound is ionic in nature or covalent in nature , by finding the difference between the electronegativity of the respective cation and anion .
The ion with higher electronegativity is the anion and the ion with lower electronegativity is the cation.
The electronegativity difference above 1.7 make the compound ionic in nature.
Hence, from the question ,
A is the cation and B is the anion.
And the electronegativity difference above 1.7 so the compound is ionic in nature.
Answer:
Newton's Third Law
Step-by-step explanation:
This is Newton's Third Law: "For every action there is an equal and opposite reaction".
The other two are:
- Newton's <em>First Law</em>: "A body at rest tends to remain at rest. A body in motion tends to remain in motion".
- Newton's <em>Second Law</em>: "Force equals mass times acceleration'"
