Answer:
NaOH = 40 g/mole
M = 10*d*m% /MW
M = 10*1.116*15/ 40
M = 4.185
––––––––––––––––––––
pH = 11 –––> pOH = 3 –––> [OH–] = 10^–3 M
M1*V1 = M2*V2
4.185* V1 = 10^–3 * 5.3
V1 = 1.27×10^–3 L = 1.27 ml
The balanced chemical reaction is written as:
<span>2K + F2 ---> 2 KF
We are given the amount of potassium metal to be used in the reaction. This will be the starting point for the calculation. We do as follows:
23.5 g K ( 1 mol / 39.1 g ) ( 1 mol F2/2 mol K ) ( 22.4 L / 1 mol ) = 13.46 L F2

Soil is made out of all of these things and covers almost all landmasses. Even below sand and rock there is soil.
In order to balance this, you have to count
each element where the elements in the reactants side and the product side
should have equal number of molecules. The balanced reaction is as follows:
KOH + H3PO4 = KH2PO4 +H2O
Gas to liquid solids are going to break the liquid
