5 0

Answer:

There are four states of matter, solid, liquid, gas, and plasma. If something is in a solid state of matter, it has a definite shape and volume. The volume of an object is the amount of space it occupies.

Problem PageQuestion Methane gas and chlorine gas react to form hydrogen chloride gas and carbon tetrachloride gas. What volume
IgorC [24]

Methane gas and chlorine gas react to form hydrogen chloride gas and carbon tetrachloride gas. What volume of hydrogen chloride would be produced by this reaction if 3.16 L of chlorine were consumed at STP.

Be sure your answer has the correct number of significant digits.

Answer: Thus volume of carbon tetrachloride that would be produced is 0.788 L

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 1 atm  (at STP)

V = Volume of gas = 3.16 L

n = number of moles = ?

R = gas constant =0.0821Latm/Kmol

T =temperature =273K=

n=\frac{PV}{RT}

n=\frac{1atm\times 3.16L}{0.0820 L atm/K mol\times 273K}=0.141moles

CH_4+4Cl_2\rightarrow 4HCl+CCl_4

According to stoichiometry:

4 moles of chlorine produces = 1 mole of carbon tetrachloride

Thus 0.141 moles of methane produces = \frac{1}{4}\times 0.141=0.0352 moles of carbon tetrachloride

volume of carbon tetrachloride =moles\times {\text {Molar volume}}=0.0352mol\times 22.4L/mol=0.788L

Thus volume of carbon tetrachloride that would be produced is 0.788 L

If an object has 25 newtons of force pushing from the left and 26 newtons of force pushing from the right the object will
IRISSAK [1]

Answer:

C. move left

Explanation:

The object will move towards the left direction due to the unbalanced forces that are acting on it.

 The resultant force on the object will be 1N in the left direction

  • The resultant force on a body is that singular force that will have the same effect as the different forces that acts on a body
  • When forces acts in opposite directions, they are subtracted
  • The object will move in the direction of the one with the greater force

So;

  Resultant force = 26N - 25N  = 1N

The body moves 1N to the left

Which of the following is NOT something that electromagnetic waves and mechanical waves have in common?
Svetlanka [38]

Answer:

D. In both, vibrations occur in a parallel direction to the direction of the wave.

Explanation:

It is not true that in both mechanical and electromagnetic waves, vibrations occur in  parallel direction to the direction of the wave.

As with all waves, they are disturbances that transfers energy without moving the materials of the medium.

  • Electromagnetic waves have only one way of propagation which is a vibration in both parallel and longitudinal direction.
  • Mechanical waves can be propagated either in a parallel direction or longitudinal direction and not both.
