Answer: C: experimentation is the best way to obtain knowledge
Explanation: When experimenting you will learn new things and better understand things from it.
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Oxidizing agent is the agent which oxidizes the other substance and itself gets reduced. It undergoes reduction reaction in which, it gains electrons and also the oxidation state of the substance gets reduced.
Reducing agent is the agent which reduces the other substance and itself gets oxidized. It undergoes oxidation reaction in which, it looses electrons and the oxidation state of the substance is increased.
For the given chemical equation:
Half reactions for the given chemical reaction:
Copper is loosing 2 electrons, thus it is undergoing oxidation reaction and is considered as a reducing agent.
Silver ion is gaining 1 electron per atom, thus it is undergoing reduction reaction and is considered as an oxidizing agent.
Hence, 
is considered as an oxidizing agent and therefore the correct answer is Option B.
Answer:
<u><em>We previously learned that digestion of carbohydrates, and in particular starches, begins in the mouth with the action of salivary amylase. This enzyme catalyzes, or speeds along, the hydrolysis of the starch molecule.</em></u>

A hydrogen atom forms one bond, an oxygen atom forms two, and carbon forms four bonds.
Answer:
Yes. Since they have more than the required reactants.
Explanation:
Zinc reduces silver nitrate to silver metal according to the following equation.
2AgNO₃ + Zn → 2Ag + Zn(NO₃)₂
From the equation 2 moles of AgNO₃ produce 2 moles of silver.
If we consider the zinc to be used number of moles=mass/RAM
RAM of zinc =65.38
No. of moles=500/65.38
=7.6476moles
To produce 800 grams of silver they require:
800/107.868 moles=7.4165 moles of silver nitrate since the ratio of silver nitrate to silver produced is 1:1
The number of moles of silver nitrate available=1500/169.872
=8.83 moles.
As the amount of reactants available is more than the required the company will make it in producing the 800 grams of silver required.
