Explanation: they contain sodium, potassium, chloride, bicarbonate, calcium, phosphate, magnesium, copper, zinc, manganese, molybdenum, copper, and chromium also.
Answer:
It should be used 2 digits to the right of the decimal point to report the result
Explanation:
When adding or subtracting two decimal numbers, the number of digits to the right of the decimal point in the result is equal to the amount with the least number of decimal places.
In this case we have 4 decimal places in 0.0136 g, 2 decimal places in 2.70 × 10-4 g and 2 decimal places in 4.21 × 10-3 g, so, the least number of decimal places is 2 and that should be the number of digits to the right of the decimal point in the result.
Then the result of the sum should be 9.66 × 10-3 g

Kb for water = 0.512 °C/m
Please hurry
Answer:100.3
Explanation:
Water is considered a universal solvent due to its polar nature, which enables it to dissolve ionic compounds and polar molecules. This is because water's charged particles form hydrogen bonds with surrounding water molecules, creating hydration shells that keep the solute particles dispersed. This unique property allows water to dissolve a variety of substances.
Water is considered a universalsolvent because of its polar nature. Being polar, water has slight positive and negative charges, making it capable of dissolving ionic compounds and polar molecules. These charged particles form hydrogen bonds with water molecules, forming hydration shells that keep the solute particles separated or dispersed in the water. This ability of water to dissolve a wide range of substances makes it a universal solvent.

Answer: Option (a) is the correct answer.
Explanation:
A metal is a substance which loses electron(s) in order to attain stability.
For example, sodium is an alkali metals with atomic number 11 and its electronic distribution is 2, 8, 1.
So, in order to attain stability sodium will readily lose 1 electron and forms ion.
Whereas non-metals are the substances which gain electron(s) in order to attain stability.
For example, atomic number of carbon is 6 and its electronic configuration is 2, 4.
To attain stability a carbon atom shares it 4 valence electrons with another atom.
Thus, we can conclude that out of the given options, Na is a metal.
