Answer:
Parasites take nutrients from another organism's body.
Explanation:
Answer:
<h3>The answer is 0.03 moles</h3>
Explanation:
To find the number of moles given the number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 2 × 10²² molecules of water
We have
We have the final answer as
<h3>0.03 moles</h3>

Answer:
you mean "jointed." jointed appendages give arthropods much greater movement flexibility and range.
Given:
Ammonia
Hydrochloric acid
To find:
The amount excess of reactant left over in ammonia.
Solution:
Ammonia reacts rapidly with hydrochloric acid to form Ammonium Chloride
Equation for the above statement is derived as:
One gram per mole of ammonia
Similarly for 6.91g of
One gram per mole of hydrochloric acid
Similarly for 4.61g of
From the above information we can say that h c l is a limiting reactant.
Limiting reactant is an element that consumes lesser product in a chemical reaction.
Thus the amount of excess reactant is calculated by using the following formula
Amount of excess reactant left over in
Result:
Amount of excess reactant left over ammonia
