Answer:inform the lab instructor and get instructions
Explanation:
If you come across a chemical in the laboratory which has been wrongly labelled, do not be quick to dilute it or take any further action. The laboratory instructor who may have prepared the reagent himself or has better knowledge about the reagent should be contacted immediately so that he/she can give you instructions about what to do with the wrongly labelled reagent.
valence electrons are the number of electrons in the outermost shell.
electron configuration is where the electrons are arranged in ascending order of energy shells
the electron configurations for the elements given are as follows
C - 2,4
Al - 2,8,3
Na - 2,8,1
Ca - 2,8,8,2
from the given elements, Aluminium has 3 electrons in its outermost shell.
answer is Aluminium
Solutions are homogeneous mixtures made up of two non-reacting compounds. The component which is present in large quantity is called as solvent and the component in small quantity is called as solute There are six types of solutions.
1. Gas (solvent) - Gas (solute) Example= Air
2. Liquid (solvent) - Gas (solute) Example= Fizzy Drinks
3. Liquid (solvent) - Liquid (solute) Example= 96% Ethanol in Water
4. Liquid (solvent) - Solid (solute) Example= Sugar in Tea
5. Solid (solvent) - Solid (solute) Example= Brass, 18 caret Gold
6. Solid (solvent) - Gas (solute) Example= Marshmellow
Result:
In equation earth air is solvent (as it is in large quantity) and water vapors (gas) which are in small quantity is solute.
So, it is Gas - Gas Solution.
It is equal to a gram, as there are 1,000,000 milligrams in a gram.
Your answer is <span>D) The angle of light from the sun as it reflects off the moon and viewed from the Earth's surface because of the way the sun hits the moon one side has to light the other doesn't and when the moon rotates the sun hits another part of the moon.
