A student places a set of books with a force of 25 n on a lab table with a force of 150 n. What is the normal force pushing upwa
abruzzese [7]

The normal force acting on the legs of the table is 175 N

The weight of the books is the force exerted by the books on the table, and it is given as:

W =25N

The force exerted by the table is given as:

F = 150N

The parameters above imply that:

  • The table and the books are stationary,
  • The force exerted by both act in the same downward direction.

So, the normal force acting on the legs of the table is calculated as follows:

F_N =F +W

Substitute known values

F_N = 150N + 25N

F_N = 175N

Hence, the normal force acting on the legs of the table is 175 N

At 900 ∘c,kc=0. 0108 for the reaction caco3(s)←→cao(s)+co2(g) a mixture of caco3, cao, and co2 is placed in a 10. 0-l vessel at
Mrac [35]

The concentration of CaCO3 increases in all cases because Q> K.

<h3>What is equilibrium?</h3>

A chemical reaction is said to have attained equilibrium when the rate of forward reaction is equal to the rate of reverse reaction. We are told that the Kc of the reaction is 0. 0108.

In the first case:

CaCO3 - 15.0 g/100g/mol/10 L = 0.015 M

CaO - 15.0 g/56 g/mol/10 L = 0.027 M

CO2 - 4.25 g/44 g/mol / 10 L = 0.0096 M

Q = [0.027] [0.0096]/0.015

Q = 0.017

Since Q > K, the concentration of CaCO3 increases

In the second case;

CaCO3 -  2.5 g/100g/mol/10 L =0.0025 M

CaO - 25.0 g/56 g/mol/10 L = 0.045 M

CO2 - 5.66 g/44 g/mol / 10 L = 0.013 M

Q = [0.045 ] [ 0.013]/[0.0025 ]

Q = 0.23

Q > K the concentration of CaCO3 increases

In the third case;

CaCO3 - 30.5 g/100g/mol/10 L =0.031 M

CaO - 25.5 g/56 g/mol/10 L =0.046 M

CO2 - 6.48 g//44 g/mol / 10 L = 0.015 M

Q = [0.046] [ 0.015]/[0.031]

Q = 0.022

Q> K hence the concentration of CaCO3 increases

Missing parts: At 900oC, Kc = 0.0108 for the reaction: CaCO3(s) <===> CaO(s) + CO2(g) A mixture of CaCO3, CaO, and CO2 is placed in a 10.0 Liter vessel at 900oC. For the following mixtures, will the amount of CaCO3 increase, decrease, or remain the same as the system approaches equilibrium?

Speed, Velocity or Acceleration?
levacccp [35]

Answer:

Velocity

Explanation:

Speed is how fast something moves.

Velocity is how fast it moves and in what direction it moves in.

Acceleration is the change in how fast it moves. I.e. if it speed up or slows down.

Here we are given the speed of the train (75mph) and the direction (north), therefore it is velocity.

Hope this helped!
