Answer:
C
Explanation:
A fuel cell uses both hydrogen and oxygen as fuels. At the cathode oxygen is reduced to water according to the equation
O2+4H^+ +4e ------>2H2O
And hydrogen is oxidized at the anode:
2H2------>4H^+ +4e
Fuel cells produce only water as a by product hence they are environment friendly
I think its A. it cant be C or D b/c we are measuring the distance between Earth and Saturn, not the speed.
The homologous series ( not homogeneous series ) of n-propyl bromide is C3H7Br. It is also known as 1-Bromopropane
n-propyl bromide or 1-bromopropane, is a solvent that is used in cleaning metals, vapor degreasing and also for dry cleaning.
<h3>What is Homologous series?</h3>
Homologous series is a family of organic compound which follows a regular structural pattern and in which successive members differs from one another by a molecular formula of CH2
Below are some of their characteristics:
- The general formula of all compounds in the series is the same.
- They have the same functional group.
- Their physical properties such as melting point, boiling point, density, generally show a gradual change with increase of molecular formula in the series.

The answer is Reduction. All three methods (convection, radiation, and conduction) are all ways of transferring heat. Convection is the transfer of heat by means of a medium such as air. Conduction is the transfer of heat from the contact of two surfaces at different temperatures. Radiation is the transfer of heat via electromagnetic waves.
Reduction is a chemical reaction that involves the gain of electrons. It is the opposite of oxidation which involves the loss of electrons.
