Answer:
1. It is stoichiometric.
2. O2 is the limiting reactant.
3. 9.0 g of C2H6 remain unreacted.
4. 17.6 g of CO2.
5. 85.2%.
Explanation:
Hello there!
In this case, for the given chemical reaction:
We can see that:
1. It is stoichiometric and is balanced because the reactants yields the products according to the law of conservation of mass.
2. In this part, it is possible to calculate the moles of ethane by using its molar mass:
And the moles of oxygen by knowing that one mole is contained in 22.4 L at STP:
Thus, by calculating the moles of carbon dioxide product by each reactant, we can identify the limiting one:
Thus, since oxygen yields the fewest moles of CO2 product, we infer it is the limiting reactant.
3. In this part, we calculate the mass of C2H6 that actually react first:
Thus, the leftover of ethane (C2H6) as the excess reactant is:
4. Since 0.4 moles of carbon dioxide were produced, we use its molar mass to calculate the mass as its theoretical yield:
5. Finally, the percent yield is gotten by dividing the actual yield by the theoretical one:
Best regards!
Answer:
The answer to your question is: letter D
Explanation:
A. a motile archaea Archea don't have peroxisomes then this option is wrong.
B. a nonmotile eukaryote The new organism has flagella then it can move, so this option is wrong.
C. a motile bacterium Bacterium don't have peroxisomes so this option is wrong.
D. a motile eukaryote This is the correct option because an eukaryote can have all the characteristics described.
Answer:
a delayed neutron is a neutron emitted after a nuclear fission event, by one of the fission products (or actually, a fission product daughter after beta decay), any time from a few milliseconds to a few minutes after the fission event.
Explanation:
Answer: As magma cools and crystallizes minerals form is predictable patterns in a process known as '<em>Bowen reaction series'.</em>
Explanation:
The sequence in which minerals crystallize out from the magma is Bowen's reaction series. The top most layer of the magma will crystallize first and slowly successive layers will cool down to form crystals.
The newly formed mineral from the cooling magma reacts again with the remaining magma further to form another series of minerals.
