Answer:

I want brainliest plz!!!

Explanation:

Sulphur dioxide gas is collected in the lab in a gas jar by upward displacement of the air because Sulphur dioxide gas is heavier than air. The gases lighter than air are collected by downward displacement of water. This discussion on Sulphur dioxide is collected in the lab in a gas jar by upward displacement of air.

indicate whether energy is emitted or absorbed when the following electronic transitions occur in hydrogen according to the Bohr

AlladinOne [14]

Answer:

A=emitted B=absorbed

Explanation:

If an electron drops down from n=2 to n=1 energy is emitted, and if the electron moves up from n=1 to n=2 energy is absorbed. The amount of energy that is either absorbed or emitted is called quanta.

What is the percent-by-mass, %(m/m), concentration of sucrose ( table sugar) in a solution made by dissolving 22.8 g of sucrose

Ede4ka [16]

Answer:

32.6 %

Explanation:

Given data

Mass of sucrose (solute): 22.8 grams

Mass of water (solvent): 47.1 grams

Step 1: Calculate the mass of the solution

The mass of the solution is equal to the sum of the mass of the solute and the mass of the solvent.

m(solution) = m(solute) + m(solvent)

m(solution) = 22.8 g + 47.1 g

m(solution) = 69.9 g

Step 2: Calculate the percent-by-mass of sucrose in the solution

We will use the following expression.

$\% m/m = \frac{mass\ of\ sucrose}{mass\ of\ solution} \times 100\% = \frac{22.8g}{69.9g} \times 100\% = 32.6 \%$
