In 1840, California was part of Mexico and gold wasn't discovered (in large quantities) until 1848. CA had a very small population in 1840 with even fewer foreigners including Americans, English/Irish, Russians, etc.
There wasn't much migration to CA in 1840, but those that did migrate, went there basically to get away from "civilization" and make a new start on life. Mexican authorities did not have much control so CA was pretty much self-governing.
There you go Hope that helped.
In order to balance both of the reactions you need to make sure that both sides of the reaction have the same number of atoms for each atom in order to follow conservation of mass.
KCl+F₂→KF+Cl₂
Notice how in the above reaction there are two chlorine atoms on the products side (right side) and only one atom of chlorine on the reactants side (left side). you want both the reactants and products side to have the same amount chlorine and to do this multiply KCl by 2. Fluorine however, has 2 atoms on the reactant side and 1 atom on the product side. to fix this multiply KF by 2. <span>Therefore the balanced reaction is: 2KCl+F₂→2KF+Cl₂
</span>notice how both sides of the reaction have equal numbers of each atom.
Mg+HCl→MgCl₂+H₂
the above reaction has 2 atoms of H on the products side and only 1 atom of H on the reactants side. That means you have to multiply HCl by 2. Now you have the equation Mg+2HCl→MgCl₂+H₂. As you can see now we have equal numbers of all the atoms on both sides which means that that is the balanced equation.
I hope this helps. Let me know if you have any further questions or need anything to be clarified.

Answer:
23.92 g
Explanation:
Molar mass of H2SO4 = (2×1)+32+(16×4)= 2+32+48= 82g/mol
H2SO4 + 2NaOH ---> Na2SO4 + 2H2O
I mole of H2SO4 = 2 moles of NaOH
24.5/82 = 24.5/82 × 2
= 0.598 moles of NaOH will neutralize
Mass= mole× molar mass
Molar mass of NaOH= 23+16+1 = 40g/mol
Mass= 0.598 × 40 = 23.92g of NaOH
