Answer:
Answers provided for the reactions with explanations in parenthesis
Explanation:
We need to find the approx. equivalent pH so we can choose an indicator.
CH3COONa +strong acid HCl - methyl orange (pH will be about 4.5)
Na2CO3 base ---> strong acid HCl- phenolphthalein (pH will be 7-8) , and then methyl orange (since carbonic acid has 2 equivalence points, it needs two indicators)
Na2C2O4 HCl- methyl orange, and then methyl orange (since oxalic acid has 2 equivalence points, it needs two indicators)
NH4Cl NaOH- Phenolphthalein, since pH = 9.75 approximately
NaOH HCl-Bromothymol blue --> since pH = 7 best for a neutral indicator
Answer:
at the nuclear reactor site
Explanation:
In the United States, liquid high-level waste is stored in underground tanks pending vitrification. High-level waste is stored at the nuclear reactor site.
Such waste was created by the weapons programs of the cold war and the Manhattan project. This waste can not be vitrified as there were not enough funds for further processing.
Japan is working to change to sustainable energy sources that can replace nuclear energy sources.
What is Nuclear energy?
Utilizing nuclear reactions to generate electricity is known as nuclear power. Nuclear fission, nuclear decay, and nuclear fusion reactions can all provide nuclear energy. Currently, nuclear power plants use the fission of uranium and plutonium to generate the great majority of the world's electricity from nuclear sources.
The only significant, carbon-free electricity source that the nation can extensively expand to produce significant amounts of electricity is nuclear energy. When fossil fuels are burned to produce the same amount of electricity, nuclear power plants avoid producing a sizable amount of emissions.

To find the concentration, use the following formula--> molarity= moles/ liters
liters= 650.0 mL= 0.6500 Liters
we need to convert the grams to moles using the molar mass of NH3
molar mass of NH3 = 14.0 + (3 x 1.01)= 17.03 g/ mol
25.0 g NH3 ( 1 mol/ 17.03 grams)= 1.47 mol
concentration= 1.47 mol/ 0.6500 Liters= 2.26 M
