The coefficient for Oxygen in the balanced reaction : 3
<h3>Further explanation</h3>
Given
Reaction
C₂H₄ + _ _ O₂ ⇒ _ _ CO₂ + _ _ H₂O
Required
Oxygen coefficient
Solution
C₂H₄ + aO₂ ⇒ bCO₂ + cH₂O
C, left=2, right=b⇒b=2
H, left=4, right=2c⇒2c=4⇒c=2
O, left=2a, right=2b+c⇒2a=2b+c⇒2a=2.2+2⇒2a=6⇒a=3
The equation becomes :
C₂H₄ + 3O₂ ⇒ 2CO₂ + 2H₂O
Answer:
In this question, consider how to correct two options:
The most successful is that a steroid hormone derived from components that contain cholesterol, this is because they are made up of lipids.
And the second correct option is that to be transported in blood fluids, THEY ARE GENERALLY (NOT ALWAYS) transported by transport proteins to their target organ, which may be close, far or even the same as the productions.
Explanation:
A variety of steroids and synthetic steroids have also been devised. Most are steroids, but some nonsteroidal molecules can interact with steroid receptors due to the similarity of their forms. Some synthetic steroids are weaker, and some much stronger, than natural steroids whose receptors they activate.
Answer:
The Answer is 2-methylpentane
Or the third one down.
Explanation:
Ok so rewrite the equation for yourself :).
N2 + 3H2 -> 2NH3 (Always check if it is balanced).
Ok so we have 2kg of hydrogen conver this to grams and then to moles.
2kg -> 2000g
2000g divide by R.M.M of H2
R.M.M
2H - 2 * 1 -> 2
2000/2 - 1000 moles.
Look at the ratio of H2 to 2NH3.
We see that we get 2NH3 for every H2 therefore the ratio is 1:2.
This means that we HAVE 2000 moles of 2NH3.
At stp. we know that 1 moles = 22.4 Litres
We have 2000 moles that means that we produce 44800 litres of NH3 at stp.
2000 * 22.4 - 44800
Hope this helps :).
