Electrons flow from the positive end of a source towards the negative end
B. carbon + oxygen -- carbon dioxide
Explanation:
The best equation that describes a reaction where carbon combines by burning in the presence of oxygen to produce carbon dioxide is:
carbon + oxygen -- carbon dioxide
Every chemical reaction is made up of reactants and products
Reactants are the species on the left hand side of an equation, the products are those on the right hand side.
The reactants combines chemically to give produces.
The kind of reaction depicted above is a synthesis or combination reaction where two species combines to gives a product or more;
C + O₂ → CO₂

Answer: I hope this helps you
Explanation:
-- A tornado follows a path that's a few miles wide, for a few hours.
Then it's all over.
-- A hurricane follows a path that's several hundred miles wide,
for a week or two, before it's over.
Then comes the rain, continuing on the same path, for another week.
Answer : 
Explanation :
Given that,
Charge of particle 1 = 
Distance x = 6 cm
Charge of particle 2 = 
Distance x = 27 cm
Total distance = 
Particle 1 is at (6,0) and particle 2 is at (27,0) .
Therefore, midway (16.5, 0)
Now, 
Formula of electric field
Now, the the electric field due to particle 1
Similarly, the electric field due to particle 2
Resultant Electric field
Hence, this is the required answer.
