Since the compound has 1.38 time that of oxygen gas at the same conditions of temperature and pressure, we have the relationship:
MW/MWoxygen = 1.38
MW = 44.16
Since there is water formed during the reaction, the formula of the compound must be:
XaHb
where a and b are the coefficients of each element.
If the compound reactions with oxygen forming water and an oxide of the element X, the combustion reaction must be:
XaHb + ((2a + (b/2))/2) O2 = a (XO2) + (b/2)(H2O)
Using dimensional analysis:
10 (1/44.16) (b/2 / 1) (18) = 16.3
Solving for b:
b = 8
The compound now is XaH8. Most probably, the compound is C3H8 since it has a molecular formula of 44 and it reacts with O2 to form water and CO2.
Answer:
O3 => CLO + O2
Explanation:
ozone gas yields one Chlorine Monoxide gas, and two Oxygen gas. i forgot how to explain it well, but I know how to do it and will help in the future if needed :)
Answer: Ba(CN)2 + (NH4)2SO4 => BaSO4 + 2 NH4CN
Explanation: The reaction will produce BaSO4 Barium sulfate and NH4CN Ammonium cyanide.
The answer is A.( The reaction is endothermic) I had it on my test and got it right
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. An example is Iron (III) , Iron (II) , lithium, and hydrogen.
