I would say C. Telling the teacher about a chemical spill
Answer: chemistry
Explanation: see definition on wikipedia.
Answer:
37.046 grams of oxygen gas were produced.
Explanation:
Moles of potassium chlorite =
According to reaction 2 moles of potassium chlorite gives 3 moles of oxygen gas.
Then 0.7718 moles of potassium chlorite will give:
of oxygen gas.
Mass of 1.1577 moles of oxygen gas:
1.1577 mol × 32 g/mol = 37.046 g
37.046 grams of oxygen gas were produced.
Answer:
the only remote information i could find about this element was sodium
dicyanidoaurate(I)
sodium dicyanoaurate(1-)
Na[Au(CN)2]
sodium dicyanidoaurate(1-)
but as you see these go towards Na[Au(CN)2] not Na[Au(CN)4], so I will leave the rest up to you.
Have a good day.

that is the website i found that off of
https://www.webqc.org/molecular-weight-of-Na%5BAu%28CN%294%5D.html
this one tells you the element names.
The best are kliometers or meters
