Answer:
Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal. An example can be seen below.
Explanation:
Elevated carbon dioxide mean too much acid in the blood. <span>Increase acid excretion (intercalated cells secrete H+ into tubules) and decrease bicarbonate excretion. They also make new bicarbonate to add to the plasma.</span>
Answer:
C2HBr
Explanation:
The empirical formula is like the simpliest form so divide all by 3 and get the above formula.
When acids react with water, H ions are released which then combine with water molecules to form H₃O⁺
Answer:
Cations are positively charged atoms and hence we need to make the atom positively charged in order to get a cation
We know that an atom is neutral as a whole, so we have equal number of electrons and protons
since we cannot mess with the number of protons in an atom, we have to do it by altering the number of electrons
If we reduce the amount of electrons in an atom, the net charge will be positive and hence a cation will be formed
