Start by balancing the hydrogen atoms. There are 9 on the reactants side and 2 on the products side. The least common multiple of 9 and 2 is 18, so the coefficient for C5H9O should be 2 and the coefficient for H2O should be 9.
Next, balance the carbon atoms. After giving C5H9O a coefficient of 2, there are 2*5, or 10 carbon atoms on the reactants side. There is only 1 carbon on the products side. The least common multiple of 1 and 10 is 10, so the coefficient of C5H9O remains as 2 and the coefficient for CO2 becomes 10.
Lastly, balance the oxygen atoms. With C5H9O having a coefficient of 2, there are 4 oxygen atoms on the reactants side. With CO2 having a coefficient of 10 and H2O having a coefficient of 9, there are 29 oxygen atoms on the products side. Here, you balance by changing only the coefficient of O2, which currently provides 2 oxygen atoms to the reactants side. 2 of the 29 oxygen atoms are covered by C5H9O, so the O2 needs to cover for the other 27. Every mole of O2 has 2 oxygen atoms, so the coefficient should be 27/2, or 13.5. We don't want decimals in the reaction, so multiply all of the coefficients by two. This gives the balance reaction:
4C5H9O + 27O2 --> 20CO2 + 18H2O
The ways in which ammonia can be identified is mentioned in below pointers.
<h3>What is Ammonia ?</h3>
Ammonia is a compound of nitrogen and hydrogen with the formula NH3.
A stable binary hydride, and the simplest pnictogen hydride.
Ammonia is a colourless gas with a distinct pungent smell.
Biologically, it is a common nitrogenous waste,
Three ways in which ammonia gas can be identified is:
- It has a sharp characteristic odor.
- When a glass rod dipped in HCl is brought in contact with the gas white color fumes of ammonium chloride are formed.
- It turns moist red litmus blue, moist turmeric paper brown, and phenolphthalein solution pink.

Answer:
118.75°C is the boiling point of a solution.
Explanation:
Mass of the solute that is barbiturates = 42.5 g
Molar mass of a solute = 184.2 g/mol
Moles of solute = 
Mass of the solvent that acetic acid = 825 g = 0.825 kg
Molality of the solution (m):
Elevation in boiling point is given as:
i = 1 (organic compound)
= Boiling temperature of solution.
T = boiling temperature of solvent that is acetic acid=117.9°C
118.75°C is the boiling point of a solution.
Explanation:
1. N/A
2. The difference in color
3. It is making the solution less concentrated, usually by adding more liquid.
4. You need to find the concentration of the solution before it was diluted. Add more of the solvent to the solute as per needed.
5.
a 1 molar solution cannot be made by adding one mole of solute to 1 L of solvent. • Solutions of a desired molality are usually prepared by placing the appropriate amount of solute
