Answer:
Approximately
, assuming that this gas is an ideal gas.
Explanation:
Look up the standard room temperature and pressure:
and
.
The question states that the volume of this gas is
.
Convert the unit of all three measures to standard units:
.
.
.
Look up the ideal gas constant in the corresponding units:
.
Let
denote the number of moles of this gas in that
. By the ideal gas law, if this gas is an ideal gas, then the following equation would hold:
.
Rearrange this equation and solve for
:
.
In other words, there is approximately
of this gas in that
.
Answer:
C6H12O6 → 2C2H5OH + 2CO2
Explanation:
Glucose is an organic molecule, specifically a sugar, with the formula C612O6 while ethanol is another organic molecule with formula; C2H5OH.
However, as rightly said in this question, ethanol can be got from glucose via a process called fermentation in the presence of a catalyst called YEAST. The balanced equation is as follows:
C6H12O6 → 2C2H5OH + 2CO2
There are 2.5 oxygen for every phosphorus atom.
Answer: OA is a balanced equation.
Explanation: For an equation to be balanced, the number of atoms and the total charge of each element in the reaction, of the product and reactant side must be the same.
Considering OA; 6 atoms of nitrogen is present in the reactant side. Shifting to the product side, 6 atoms of nitrogen is also present. Taking the other element in the reaction into account, the number of atoms of each element balances on both sides.
