Answer:
Slow step is the rate determining step.
Explanation:
In general a reaction occurs in two or more elementary steps. Rate of reaction of each step is different. In chemical kinetics, rate of overall reaction is decided by rate of slowest step.
Consider the given reaction,
The given reaction has two elementary steps.
Step 1: H2(g)+ICl(g)→HI(g)+HCl(g) (slow)
Step 2: HI(g)+ICl(g)→I2(g)+HCl(g) (fast)
Step 2 is fast and completes in no time. Whereas step 1 is slow. As reaction cannot go to completion without step 1, so rate of the reaction is decided by rate of the slowest step.
The thick soil accumulation of fine-grained particles is called as silt
All of these properties are known as physical properties.
Physical properties are such that they are measured without changing the composition of the of the matter which is under consideration. For example, the melting point of a substance may be tested without changing its composition. The change is also reversed easily. Physical properties are used to describe and observe matter. The other type of properties are chemical properties, which require the composition of a substance to be changed for them to be measured.
Answer:
There is a mass of 154 Grams of Carbon Dioxide.
Explanation:
One mole is equal to 6.02 × 10^23 particles.
This means we have 1.05 X 10^24 total particles of Ethane.
Each ethane particle contains 2 carbon atoms.
If every particle of ethane is burned, we will end up with 2.10 x 10^24 molecules of Carbon Dioxide (Particles of Methane x 2, since each Methane particle contains 2 carbon atoms)
Carbon Dioxide has a molar mass of 44.01 g/mol
So if we take our amount of Carbon Dioxide molecules and divide it by 1 mole, ((2.10 x 10^24)/(6.02 x 10^23) = 3.49) we find that we have 3.49 moles of Carbon Dioxide.
Now all we need to do is multiply our moles of carbon dioxide(3.49) by it's molar mass(44.01) while accounting for significant digits.
What you should end up with is 154 Grams of Carbon Dioxide.
Hope this helps (And more importantly I hope I didn't make any errors in my math lol)
As a side note this is all assuming that this takes place at STP conditions.
