Answer:
commensalism
(hope i spelled that right)
Explanation:
if the bird only nest in it and
the tree isn't really bothered or affected by the bird.
Taking into account the reaction stoichiometry, 5.33 moles of NH₃ are formed from the complete reaction of 16 grams of H₂.
<h3>Reaction stoichiometry</h3>
In first place, the balanced reaction is:
N₂ + 3 H₂ → 2 NH₃
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- N₂: 1 mole
- H₂: 3 moles
- NH₃: 2 moles
The molar mass of the compounds is:
- N₂: 14 g/mole
- H₂: 2 g/mole
- NH₃: 17 g/mole
Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
- N₂: 1 mole ×14 g/mole= 14 grams
- H₂: 3 moles ×2 g/mole= 6 grams
- NH₃: 2 moles ×17 g/mole=34 grams
<h3>Mass of NH₃ formed</h3>
The following rule of three can be applied: if by reaction stoichiometry 6 grams of H₂ form 2 moles of NH₃, 16 grams of H₂ form how many moles of NH₃?

<u><em>moles of NH₃= 5.33 moles</em></u>
Then, 5.33 moles of NH₃ are formed from the complete reaction of 16 grams of H₂.

Answer:
(D) (CH3CH2)2NH
Explanation:
In order to decide which base is strongest we need to calculate its PKb
PKb = -log [Kb]
A large Kb value and small PKb value gives the strongest base
Compound Kb PKb
(A) C6H5NH2 - 4 x 10^-10 9.349
(B) NH3 1.76x 10^-5 4.754
(C) CH3NH2 4.4x 10^-4 3.357
(D) (CH3CH2)2NH 8.6x 10^-4 3.066
(E) C5H5N 1.7x10^-9 8.77
Clearly (CH3CH2)2NH is the strongest base.
Answer:
I know some of them...
Explanation:
1. What was the purpose of the experiment?
Type your answer here: The purpose of this experiment is to show that a cell membrane is a type of barrier, and is permeable to some substances, but may not be permeable to all substances.
2. What were the independent, dependent, and control variables in your investigation? Describe the variables used in the part of the experiment with the eggs.
Type your answer here: Independent variable / Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. This variable is modified during the experiment to analyze how another variable responds to it. The researcher wants to study how the changes in these variables affect the dependent variable. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them.
Dependent variable / Responding variable: Its response depends on any change in the independent variable. The dependent variable is the one that is being investigated, studied, and measured. It represents a quantity of something which value depends on how the independent variable is modified. It is usually identified by the letter Y. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the egg circumference.
Constants / Controlled variables: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example the use of the lid to seal the jar and the amount and concentration of vinegar might be considered as a controlled variable. These elements are used but do not provoke any change in the size of the egg.
thats it... CAN SOMEONE ANSWER THE OTHERS?! I NEED ITT
Answer:Acceleration due to gravity on the moon is 1/6 times as that on the earth and we know that mass is property of the material it always remains same and weight is measure of gravitational force, hence
mass of object on moon is 60kg and weight =60g/6=10×10=100N
