Answer:
Overall reaction
H2(g) + 2ICI(g) -----> I2(g) +2HCl(g)
Overall Rate = k1[H2] [ICl]
Explanation:
Overall reaction
H2(g) + 2ICI(g) -----> I2(g) +2HCl(g)
The overall reaction is the sum of the two two reactions shown in the question. After the two reactions are summed up properly, this overall reaction equation his obtained.
Since K1<<K2 it means that step 1 is slower than step 2. Recall that the rate if reaction depends on the slowest step of the reaction. Hence
Overall Rate = k1[H2] [ICl]
<u>Answer:</u> All the flasks contain same number of molecules.
<u>Explanation:</u>
STP conditions are called as standard temperature and pressure conditions.
At this condition, 1 mole of a gas occupies a volume of 22.4 L
Also,
The temperature at this condition is taken as 273.15 K and the pressure at this condition is taken as 1 atm.
According to mole concept:
1 mole of a gas occupies number of molecules
We are given:
Three different flasks having three different gases at STP
So, all the flasks will have same number of molecules that is
Hence, all the flasks contain same number of molecules.
Double replacement i believe
Answer:
b. 16 protons, 18 neutrons, and 18 electrons
Explanation:
Things to be remembered
Negative charge on any ionic species indicates gained the electrons
Positive charge on any ionic species indicates lost the electrons
A sulfur atom has 16 protons, 18 neutrons, and 16 electrons, A sulfide ion has a 2– charge which indicates that sulphur has gained two electron from any other atom, ion or species!
