Answer:
The correct option is: D. A suspension
Explanation:
A suspension is a type of heterogeneous mixture in which solid particles are suspended through out the bulk of the solvent through mechanical agitation. The solid phase is also known as the internal phase and the solvent is known as external phase. In a suspension, the solid particles are generally larger than one micrometer and thus are unable to dissolve in the medium. The solid particles of a suspension are large enough to get precipitated.
<u>Therefore, in the given situation, the chicken broth is </u><u>a suspension</u><u> </u>as the contents or solid particles of the container needs to be suspended in the solvent by shaking to prevent sedimentation.
Answer:
D.
Explanation:
Nuclear energy does not have greenhouse gas emissions. The emissions produced by nuclear fission plants are similar to renewable energy sources.The generation of power using nuclear energy does not affect air quality thus providing a clean source of energy.Nuclear energy originates from radioactive material which are harmful to living organisms.
The volume of cylinder is 100 mL, inner diameter is 3.2 cm thus, radius will be:
Volume of layer formed=
...... (1)
Volume of layer is also equal to sum of volume of gasoline and water.
Density of gasoline is 
and mass is 34 g thus, volume of gasoline will be:
Now, density of water is 
and mass is 34 g thus, volume of water will be:
Adding both the volumes, volume of layer will be:
Putting the values in equation (1) to solve for height of the layer,
Thus, height of layer is 10.25 cm

Answer:
C₂H₆
Explanation:
To obtain molecular formula of the gas, you need to find first its molecular mass.
To find molecular mass you need to obtain moles of gasbecause molecular mass is the ratio between mass of the gas and the volume it occupies.
As at STP, 1 mole of a gas occupies 22.4dm³, 1dm³ of gas are:
1dm³ × (1mol / 22.4dm³) = 004464moles.
Its molecular mass is:
1.35g / 004464moles =
30.24g/mol
Now, if the gas is 80%C and 20%H, its <em>empirical formula (Simplest ratio of atoms in a molecule) </em>is:
80% Carbon × (1mol / 12.01g) = 6.66moles C
20% Hydrogen × (1mol / 1.01g) = 19.8moles H
Ratio of H:C is:
19.8 mol H / 6.66mol C = 3
Thus, you can know you will have 3 moles of Hydrogen per mole of Carbon, CH₃ (It weighs 15.04g/mol)
As the gas weighs 30.24 ≈ 2 CH₃
The molecular formula is:
<h3>C₂H₆</h3>
