Answer:
C6H12O6+6O2->6CO2+6H2O
Explanation:
You need to start in for the given Questions think in a way what will you need a number for fit to the chemical name. I would suggest if you need practice because sometimes it goes higher when you are chemistry student especially involved in fraction. Thank you for listening
Answer:
3.0 mol H₂O
Explanation:
Step 1: Write the balanced combustion equation
C₂H₆ + 3.5 O₂ ⇒ 2 CO₂ + 3 H₂O
Step 2: Establish the appropriate molar ratio
The molar ratio of C₂H₆ to H₂O is 1:3.
Step 3: Calculate the moles of H₂O formed from 1.0 mole of C₂H₆
1.0 mol C₂H₆ × 3 mol H₂O/1 mol C₂H₆ = 3.0 mol H₂O
The nickel, itself ferromagnetic, reduces the magnetism in stainless steel but not to zero. Austenitic stainless steel is defined as the steel crystal structure that is face centered cubic which is the same structure hot iron has as one of the allotropes of iron. Nickel above a certain percentage (18) stabilizes austenite structure just as if you took carbon steel and heated it above 730–770 C. Above this temperature the structure is FCC and above the Currie temperature where magnetism is killed due to the isotopic symmetry of the structure. However, you can still get a small magnetic attraction from austenitic stainless steel if it is cold worked, heat treated a certain way or welded. So it is not a guarantee that austenitic stainless is totally non magnetic.
To solve this question, we first need to know the mass of one mole of mercury. This can be done by checking the periodic table.
From the periodic table, we can see that:
molar mass of mercury = 200.59 grams/mole.
From the measurements, the chemist found that the participated amount of mercury is 0.02 moles.
We can simply determine the mass of 0.02 moles by doing cross multiplication as follows:
mass of 0.02 moles = (0.02 x 200.59) / 1 = 4.0118 grams
Rounding the answer to 2 significant digits, we get:
mass of 0.02 moles = 4.01 grams
No it does not it cooks the same speed
