Answer: The 234.74 grams of sample should be ordered.
Explanation:
Let the gram of 114 Ag to ordered be
The amount required for the beginning of experiment = 0.0575 g
Time requires to ship the sample = 4.2hour = 252 min(1 hr = 60 min)
Half life of the sample = = 21 min
The 234.74 grams of sample should be ordered.
Answer:
3AlCl₃
Explanation:
molar mass of aluminum chloride AlCl₃ is 133.33 g/mole
133.33 times 3 is 400
put 3 in front of AlCl₃
3AlCl₃

Answer:
A chemical change occurred and a gas was produced.
Step-by-step explanation:
If there is no chemical reaction, the <em>Law of Conservation of Mass</em> says that
Total mass = Mass 1 + Mass 2
However, if the two liquids react and give off a gas, then
Total mass = Mass 1 + Mass 2 + Mass of gas
You are not measuring the mass of the gas, so the mass of the liquids after mixing is less than it was before mixing.
For example, if Liquid 1 was a solution of HCl and Liquid 2 was a solution of Na₂CO₃, they would give off CO₂ on mixing. but you would not be measuring the mass of the CO₂.
