I think it's N and O because on the left 3 times 2 gives you O6 on the left but O3 on the right. Then on the right 1×2= N2 but on the right it's just N1
Hello there,
The moment the tablet<span> starts </span>dissolving<span> a chemical reaction occurs that </span>Some<span> factors can change how quickly the carbon dioxide gas is produced. Stir the ice cubes in the jar for about a </span>minute<span> so that the temperature evens out.
</span>
he tablets<span> effervesce, or fizz, when </span>dropped into water. Some<span> factors that influence the speed of a chemical reaction are: (1) Pour the </span>water<span> into 3 separate </span>glass<span> beakers.
</span>
When the solid<span> material has </span>completely<span> disappeared and the bubbles have vaneished. Stir for a </span>minute<span> or two so that it mixes in.

Hope this helped
This is a difficult task because zinc is much more active than copper and could hardly be passivated. ... The sur- face immediately turns white (the color of copper(I) iodide) and the yellow-brown color of iodine quickly fades. Rinse the coin with water, brighten it with polish and cloth and begin the whole process again.N
When a block of ice is placed in a frying pan, it is first in a solid state, meaning that the particles are moving slowly and are tightly compacted together as well as vibrating. As the the temperature of the pan increases, the state of matter will go from a solid to a liquid, which will cause the thermal energy in the ice cube to increase and the particles will go from a vibrating state, to sliding state. By this time the ice will now be water. As the temperature of the pan continues to increase, the water will eventually become water vapor and turn into a gas because as the particles are heated, they will move faster causing them to expand.
It is 5n , that’s it the difference between the 10n and the 15 n
