1.2mole•20.17g/1mole= 24.20g
Answer:
It will cost $68,620.5 to the club to add the grass turf to their field.
Explanation:
length of the field = l = 0.102 km = 0.102 × 1000 m
( 1km = 1000 m)
Width of the field w = 0.069 km = 0.069 × 1000 m
Area of the field , A= l × w

Cost of grass turfing = 
Cost of grass turfing on field of
:

It will cost $68,620.5 to the club to add the grass turf to their field.
Answer:
un electrón
En la reacción entre el litio y el oxígeno, el litio cede su electrón de valencia al átomo de oxígeno. Como puede verse en la animación de la derecha, dos átomos de litio reaccionan con un átomo de oxígeno. Cada átomo de litio le da un electrón al átomo de oxígeno.

Chemical sanitizer effectiveness, decreases with increase in pH . And most soap and detergent are alkaline in nature, that limits its effectiveness. So they should be rinsed off completely for proper effectiveness of santizer. So improper rinsing limits the effectiveness of a sanitizer.
So , the answer is improper rinsing after that still a detergent residue remains limits the effectiveness of sanitizer.
Answer : The correct options are,
and 
Explanation :
Single displacement reaction : It is a type of chemical reaction in which the more reactive element displaces the less reactive element.
Option A reaction : 
It is an example of double displacement reaction because in this reaction a positive cation and a negative anion of the two reactants exchange their places to form two new products.
Option B reaction : 
It is an example of single displacement reaction.
Option C reaction : 
It is an example of combination reaction because in this reaction two reactants react to give a single product.
Option D reaction : 
It is an example of decomposition reaction because in this reaction a single reactant decomposes into two or more products.
Option E reaction : 
It is an example of single displacement reaction because in this reaction the most react element, aluminium displaces the less reactive element, hydrogen.
Hence, the options B and E are single displacement reactions.
