Answer:

The war of the currents, sometimes called battle of the currents, was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s.

acetylene gas c2h2 undergoes combustion to produce carbon dioxide and water vapor How many grams of water are produced by the sa

ella [17]

<u>Answer:</u> The amount of water produced in the given reaction is $0.692x$ grams.

<u>Explanation:</u>

Let us assume that the initial amount of acetylene gas given be 'x' grams. Now, to calculate the number of moles, we will use the formula:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ ....(1)

Given mass of acetylene = x grams

Molar mass of acetylene = 26 g/mol

Putting values in above equation, we get:

$\text{Number of moles of acetylene}=\frac{xg}{26g/mol}=\frac{x}{26}mol$

The reaction of combustion of acetylene is given by the equation:

$2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O$

By Stoichiometry of the reaction:

2 moles of acetylene produces 2 moles of water.

So, $\frac{x}{26}$ moles of acetylene will produce = $\frac{2}{2}\times \frac{x}{26}=\frac{x}{26}$ moles of water.

Now, to calculate the amount of water produced, we use equation 1:

Molar mass of water = 18 g/mol

Moles of water = $\frac{x}{26}mol$

Putting values in equation 1, we get:

$\frac{x}{26}mol=\frac{\text{Mass of water}}{18g/mol}$

$\text{Mass of water}=\frac{x}{26}\times 18=0.692x$ grams

Identify the term that applies to each definition.

Illusion [34]

Answer:

A. Reference blank

B. Cuvettes

C. Transmittance

D. Absorbance

E. Wavelength

Explanation:

A reference blank is a sample prepared using the solvent and any other chemicals in the sample solutions, but not the absorbing substance.

A square-shaped container, typically made of quartz, designed to hold samples in a spectrophotometer is known as Cuvettes.

A measurement of the amount of light that passes through a sample or percentage of light transmitted by the sample, with the respective intensities of the incident and transmitted beams is called Transmittance.

The measurement of the amount of light taken in by a sample is known as Absorbance

The wavelength is also the distance travelled by the wave during a period of oscillation. In spectrophotometry, the unit is inversely proportional to energy and commonly measured in nanometers
