Explanation:
Because two sides don't have an equal number of O atoms. The left side has 6 O atoms (3*2) while the right side has only 1 O atom. to balance the equation, you need an equal number of atoms on both sides.
Answer: The ΔH of the reaction if 51.3 g of 
reacts with excess 
to yield 1387.6 kJ is 432.27kJ
Explanation:
To calculate the moles, we use the equation:
moles of
As is present in excess, is the limiting reagent as it limits the formation of product.
If 3.21 moles of methane releases heat = 1387.6 kJ
Thus 1 mole of methane release=
Organisms with albinism hard to find in nature because Albino coloration reduces an organism's chance of survival. The correct option is B
Explanation:
The congenital defect in which there is an absence of any pigmentation in organism or plant is termed albino. Tyrosinase enzyme controls the dose of melanin in the skin if there is a defect in Tyr gene the albinism occurs.
They are unable to protect itself from UV rays and are unable to protect itself from predators as they lack camouflage (in case of alligators). The beautiful colour of skin makes them prey for poaching.
The person with albinism have pink or red eye as the pigment of iris is also absent.
The albinism can be due to mutation. Heredity, diet, environment or disease.
In plants lack of chlorophyll is a condition of albinism which prevents photosynthesis and hence no survival.
