- Hope that helps! Please let me know if you need further explanation.
Answer:
+3
Explanation:
Chlorine is anion with a -1 charge. But they are three chlorine atoms.
-1 * 3 = -3
So they have a -3 charge.
So to balance the compound, the nickel has to be a cation with a +3 charge.
-3 + 3 = 0
Furthermore, a chemical bond always has a 0 charge. Remember that.
Hope it helped! Rate my answer a 5 star if correct.
So first find the volume
so 7.78g/ml and (3.7505 times 10^4) grams
therefor we dividde (3.7505 times 10^4) by 7.78 and get how many ml
the answer is 4820.69 ml
kL means kilo lieters
kilo=1000
kL=1000Liters
ml=milileters=1/1000 leiter
1000ml=1L
therfor
1kL=1000L
1000L=1000 times (1000ml)
1000L=1,000,000ml
1kL=1,000,000ml
so to convert to kL divide 4820.69 by 1,000,000
0.00482069
convert to scientifiic notation
4.8 times 10^-3
the answer is 4.8 times 10^-3 kL
Answer:
Speed, 
Explanation:
The device which is used to accelerate charged particles to higher energies is called a cyclotron. It is based on the principle that the particle when placed in a magnetic field will possess a magnetic force. Just because of this Lorentz force it moves in a circular path.
Let m, q and V are the mass, charge and potential difference at which the particle is accelerated.
The work done by the particles is equal to the kinetic energy stored in it such that,
v is the speed with which the particles enter the cyclotron
So,
So, the speed with which the particles enter the cyclotron is . Hence, this is the required solution.
