Answer:
carbon reduction we can extract a base metal from its ore via reduction of fused metal oxide using carbon whereas, in thermite process, we use aluminium powder instead of carbon.
<span>: The empirical formula for the compound is C3H60 (see below)
CO2 is the only product containing C,
C produced = 145.0 mg CO2 x (1 g / 1000 mg) x (1 mole CO2 / 44.0 g CO2) x (1 mole C / 1 mole CO2) = 0.00330 moles C.
H2O is the only product containing H,
H produced = 59.38 mg H2O x (1 g / 1000 mg) x (1 mole H2O / 18.0 g H2O) x (2 moles H / 1 mole H2O) = 0.00660 moles H.
Oxygen is in both and the unknown reacts with oxygen(in the air)
0.00330 moles C x (12.0 g C / 1 mole C) = 0.0396 g C = 39.6 mg C
0.00660 moles H x (1.01 g H / 1 mole H) = 0.00667 g H = 6.7 mg H
Because the unknown weighed 63.8 mg and consists off justC, H, and O, then
mass O = g unknown - g C - g H = 63.8 mg - 39.6 mg - 6.7 mg = 17.5 mg = 0.0175 g
0.0175 g O x (1 mole O / 16.0 g O) = 0.00109 moles O
The mole ratio of C:H:O is:
C = 0.00330
H = 0.00660
O = 0.00109
Divide by the smallest you get:
C = 0.00330 / 0.00109 = 3.03
H = 0.00660 / 0.00109 = 6.06
O = 0.00109 / 0.00109 = 1.00</span>
If you go backwards two elements, you will find Neon (Ne). If you go forwards six, you will find Argon (Ar). so the closest will be neon
Answer:
Because the molecules of the mixture would be compact or bond together at room temperature. In this case, both gases will condense to form water (or ice, if the room temperature is prolonged) and such droplets of water will not cause a balloon to spontaneously explode at room temperature.
Explanation:
A mixture of hydrogen and oxygen will form water. Recall that the chemical formula for water is H₂O, where H represents Hydrogen and O represents Oxygen.
A balloon is a light (not thick) solid substance with a thin membrane when blown or filled with some elements or gases.
Room Temperature means cool or cold temperature. You already know that generally at room temperature, the molecules of any substance will stick together or will become less mobile (less spontaneous).
In this case, hydrogen gas and oxygen gas will go through a process called condensation - to form water - and then through the process called freezing - to form ice.
At room temperature, the gases will first change state (state of matter) from gaseous to liquid and then from liquid to solid.
This is why the balloon will NOT spontaneously explode.
