Answer:
The set of coefficients that would correctly balanced the equation
NaCl → Na + Cl2 is the option D
(2,2,1)
Explanation:
In this reaction sodium chloride splits into sodium and chlorine.
For balancing the equation we should have number of atom of the element in the left hand side equal to the number of atom of the same element in the right-hand side.
so here in left hand side only one sodium and one chlorine is given and in the right-hand side one sodium and two chlorine is given.
So for the balancing the equation both the side should be same.
So we will write the balanced equation as
2NaCl → 2Na + Cl2
So, right now it is balanced that is two sodium and two chlorine on the left hand side as well as the right hand side.
Hence the coefficients are
2, 2, 1
Answer:
7.5 km/h (2.1 m/s) due east
Explanation:
The average velocity of the person is given by:
where
d is the displacement
t is the time taken
In this problem,
d = 15 km is the displacement
t = 2.0 h is the time elapsed
so the average velocity is
and the direction is the same as the displacement (east).
We can also convert the velocity into SI units (m/s). We have:
d = 15 km = 15,000 m
t = 2.0 h * 3600 s/h = 7200 s
Answer:
Fcoso-f =ma. F= ma 15 = 4.5 a then get acceleration. Fcoso- umg = ma then get friction
Answer:
Energy
Explanation:
The stronger the force it has the more quickly the bonds will break
As there will be more energy they will vibrate more and the bonds will separate easily..
Answer: The earth gets more energy from the sun because the sun is most close to the Earth.
