Answer: The theoretical yield is 6 rings.
Explanation:
Theoretical yield is predicted or estimated value.
Jeweler used 2 sapphires for 1 ring
Then for each sapphire there will be = 
rings are used
For 12 sapphire = 
will be used
Out of 10 rings 6 rings with 2 sapphires will be made.
The theoretical yield is 6 rings.
Explanation: Number of moles of water = mass of water/ molar mass.
Molar mass of H2O = (1*2) + 16 = 18.0
Now we only need to calculate the number of moles of water.
The chemical reaction is as follows
CH4 + 2O2 ---> CO2 + 2H2O
From the eqn, the moles of H2O = 2*moles of CH4
Molar mass of CH4 = 12 + 4 = 16. Number of moles of methane = mass/
molar mass. No of moles = 6.4/16 = 0.4. So the number of mole of water = 2* 0.4 = 0.8. We already calculate its molar mass earlier. So mass of water = molar mass * number of moles = 18 * 0.8 = 14.4
Answer:
Hydrogen
Explanation:
Hydrogen has only 1 proton and has an atomic mass of 1. It does not have neutrons. Helium and above have higher mass than Hydrogen.
the correct answer is Carbon. I put hydrocarbon and it was wrong Carbon is 100% correct.
For machines such as a rake the output force is less than the input force. If the input force of the rake is 10 newtons and the output force is 5 Newtons mechanical advantage is .5
