The mass of water that will be needed to make the solution is calculated as below
% solution = mass of the solute/mass of the solvent(water) x100
% solution = 5% = 5/100
mass of the solute =0.377 g
mass of the solvent = ?
let the mass of the solvent be represented by Y
= 5/100 =0.377/y
by cross multiplication
5y= 37.7
divide both side by 5
y =7.54 grams
Answer: Option (c) is the correct answer.
Explanation:
Generally, when we move from top to bottom in a group then there occur increase in the number of electrons due to which there will also occur increase in the number of shells.
As atomic size is the distance between the nucleus and valence shell of an atom. Hence, more is the number of shells present in an atom more will be its atomic radius.
Thus, we can conclude that the statement atomic radius of elements in a group decreases as you go from top to bottom, is generally FALSE.

Answer:
Transitional metals are good conductors of both heat and electricity.
But since there aren't any. It could be Calcium.
Answer: try to understand coz the question is not valid
Explanation: Explain the relationship between forward and reverse reactions at equilibrium and predict how changing the amount of a reactant or product (creating a stress) will affect that relationship.For example (select one from each underlined section)If the amount of (reactant or product) increases, the rate of the (forward or reverse)reaction will (increase or decrease)to reach a new equilibrium. If the amount of (reactant or product) decreases, the rate of the (forward or reverse)reaction will (increase or decrease)to reach a new equilibrium. Procedure: Access the virtual lab and complete the inquiry experiment
