A sample of co2 solid and co2 gas differ in their
Answers
CO2(s) is a solid.
CO2(g) means it is gas.
So they differ in their physical properties.
Physical propertiers means that they differ in their look.

Final answer:
If an average cell phone is dropped from a typical cruising altitude of an airplane, neglecting air resistance, it would take about 107 seconds to reach the ground.
Explanation:
The subject this question falls under is physics because it involves the physical principles of gravity and free fall. If we ignore air resistance (a common simplification in basic physics problems), we can solve this problem by employing the equation for the time (t) of a free-falling object:
t = √(2h/g),
where h is the height the object falls from and g is acceleration due to gravity (about 9.8 m/).
Notice that we would need to first convert 37,000 feet to meters (about 11,277.6).
By substituting these values into our formula, we get a value that indicates that a phone falling from the typical cruising altitude of an airplane would take about 107 seconds to hit the ground.

A is marking the solvent molecules which is marked in blue. And B is marking the whole solution.
Option C
Explanation:
A solution is defined as the homogeneous mixture of a solute in a solvent in a range of concentration where generally solvent is more in amount than in solution.
A solute is the component of the solution which is generally less in amount and is homogenously mixed with the solution. Here they are marked in blue. And the molecules that are representing the solvent are marked in orange colour. The solute and the solvent total makes the solution which is marked by B.

Yes, Sharpies contain volatile solvents—and when inhaled these solvents can produce a "high." The effects of inhalants (including Sharpies) can be similar to those of alcohol and include slurred speech, lack of coordination, euphoria, and dizziness.

Answer: The average rate of the reaction is
Explanation:
To calculate the molarity of hydrogen gas generated, we use the equation:
Moles of hydrogen gas =
Volume of solution = 250 mL = 0.250 L (Conversion factor: 1 L = 1000 mL)
Putting values in above equation, we get:
Average rate of the reaction is defined as the ratio of concentration of hydrogen generated to the time taken.
To calculate the average rate of the reaction, we use the equation:
We are given:
Concentration of hydrogen generated = 0.1564 M
Time taken = 20.0 minutes
Putting values in above equation, we get:
Hence, the average rate of the reaction is
