Answer:
The work done is 2,907 J
Explanation:
Work is one of the forms of energy transmission between bodies. To perform a job, you must exert a force on a body and it moves. In other words, when a force is applied to a body and it moves, work is done.
The work is equal to the product of the force by the distance and by the cosine of the angle that exists between the direction of the force and the direction that the moving point or object travels:
W = F * d * cos α
In the International System of Units the Force is expressed in newtons and the distance in meters, so the work will have units of newtons. Meter = joules (J).
In this case:
Replacing:
W= 255 N* 11.4 m* cos 0
Solving:
W= 255 N* 11.4 m* 1
W= 2,907 J
<u><em>The work done is 2,907 J</em></u>
Answer:
53.85%
Explanation:
Data obtained from the question include:
Mass of antimony (Sb) = 27.6g
Mass of Fluorine (F) = 32.2g
Mass of compound = 59.8g
Percentage composition of fluorine (F) =..?
The percentage composition of fluorine can be obtained as follow:
Percentage composition of fluorine = mass of fluorine/mass of compound x 100
Percentage composition of fluorine = 32.2/59.8 x 100
= 53.85%
Therefore, the percentage composition of fluorine in the compound is 53.85%
All you do is make it 2H3PO4 --> H4p207 + H20. My teacher always tells us when the reactant side is an odd number just add a two and go from there I have found that it always works
Answer:
Reaction Rate is the measure of the change in concentration of the disappearance of reactants or the change in concentration of the appearance of products per unit time
