Answer is C. in a reaction mole stays the same but mass changes and since it produced gas it means now we have less mass.
Answer:
34.6 cm³
Explanation:
<em>A chemistry student needs 55.0 g of carbon tetrachloride for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of carbon tetrachloride is 1.59 g/cm³. Calculate the volume of carbon tetrachloride the student should pour out. Be sure your answer has the correct number of significant digits.</em>
Step 1: Given data
- Mass of carbon tetrachloride (m): 55.0 g
- Density of carbon tetrachloride (ρ): 1.59 g/cm³
Step 2: Calculate the required volume of carbon tetrachloride
Density is an intrinsic property of matter. It can be calculated as the quotient between the mass of the sample and its volume.
ρ = m/V
V = m/ρ
V = 55.0 g/(1.59 g/cm³)
V = 34.6 cm³
The chemistry student should pour 34.6 cm³ of carbon tetrachloride.
Answer:
The correct answer is - They are mechanical waves.
Explanation:
Atomic bombs after detonated they send a shock wave that makes a movement of particulate matter that leads to transfer of a high amount of energy that superheats the air medium that travels as a mechanical shock wave.
The shock wave that is sent out by a detonated atomic bomb is a longitudinal mechanical wave that transfers the energy to the neighboring particles of the air.
