Answer:
Acids and bases are used in most many chemical reactions in chemistry . They are responsible for most colour changes in a chemical reaction and are used to adjust the pH of chemical solutions.
Explanation:
Answer:
2 moles of solute.
Explanation:
Molarity is defined as number of moles of solute present in one litre of solution.
Hence one molar solution of NaCl means 1 mole of NaCl is present in 1 litre of solution.
Molarity = 
For 1 litre of solution 1 mole of solute is required to make a one molar solution.
Hence for 2 litres of solution we require 2 moles of solute to keep it one molar.
Answer:
Hydrogen Gas
Explanation:
The hydrogen gas now in the test tube is flammable. So when I hold the tube over the flame, the hydrogen gas ignites and creates a popping sound. It is like a tiny bomb or fireworks.
Hope this helped! :)
Yes simplify. Anybody educated in chemistry can look at the equation and see that you have Fe+2 and CO3-2 combined to make FeCO3. But you don't need the 2s. Always simplify the subscripts.
By the way, the equation is not fully balanced. Check KBr.
I will give me a second:)))))
