Answer:
The equation is already balanced. There's an equal number of materials on each side of the equation.
Answer: The 
value is 0.664
Explanation:
Distance travelled by solvent front = (7.7-1.45)cm = 6.25 cm
Distance travelled by unknown = (5.6-1.45) cm = 4.15 cm
The retention factor or the value is defined as the ratio of distance traveled by the unknown to the distance traveled by the solvent front.
Thus the value is 0.664
The area where the periodic table has the highest electronegativity are Groups 1 and Groups 7 because they are close on giving away an electron and the other is close to becoming stable.
Answer:
active transport
Explanation:
Active transport -
It refers to the movement of the molecules from a region of lower concentration towards a region of higher concentration via a membrane , is referred to as active transport.
The process of active transport need to have some cellular energy .
Hence,
The concentration of potassium is maintained in the red blood cells via the process of active transport.
Its FeSO3 or iron(iii)sulfite = Fe2(SO3)3
