The vertical columns may also be called "groups".
Explanation:
Reactants can be referred to as starting materials for a chemical reaction. They undergo a change to form products. Reactants are usuallyconsumed in the reaction process.
Reactants are written at the left side before the arrow sign in a reaction.
Products are the ending materials of a reaction. They are what is left after the reactants has been consumed.
Prpducts are written on the right side after the arrow sign in a reaction
Basically, a reaction is given as;
Reactants --> Products
A + B --> C + D
A and B are reactants and C and D are products
In the reaction;
“carbon plus oxygen makes carbon dioxide”
C + O2 --> CO2
The reactants are; C and O2.
The product is CO2
Answer: The molarity of a solution made by dissolving 12.6 grams of NaNO3 to make 200 ml of solution is 0.74 M
Explanation:
Molarity is defined as the number of moles of solute dissolved perliter of the solution.
where,
n= moles of solute
= volume of solution in ml = 1000 ml
Now put all the given values in the formula of molarity, we get
Thus the molarity of a solution made by dissolving 12.6 grams of NaNO3 to make 200 ml of solution is 0.74 M
Answer: -
Thus the isotope that has atoms with 3 neutrons, 3 protons, and 3 electrons
4) ⁶Li
Explanation: -
Number of neutrons = 3
Number of protons = 3
Mass number = number of neutrons + number of protons
= 3 + 3 = 6
Atomic number = number of protons = 3
Element with atomic number 3 = Lithium Li
Thus the isotope that has atoms with 3 neutrons, 3 protons, and 3 electrons
= ⁶Li
