Two students apply force to a box at rest on the floor.

Chemistry
1 answer:
Scilla [17]4 years ago
6 0

Answer:

10 N Left

Explanation:

Given parameters;

   Forces acting on the box

Left force  = 40N

Right force = 30N

Unknown:

Net force on the box and the direction = ?

Solution:

Force is a pull or push on a body;

                            ←   BODY →

                        40N                30N

The forces acting on the body are in the opposite directions, the greater force will determine the direction of pull.

  Net force  = Left force - Right force  = 40 - 30 = 10N

The force will be directed left with a net value of 10N

Answer:

The pressure is 16, 9 atm

Explanation:

We use the formula PV=nRT. The temperature in Kelvis is: 273 + 25 = 298K

PV=nRT  P =(nRT)/V

P= (0, 450 mol x 0,082 l atm/K mol x 298)/0,650 l= 16, 91723077atm

In the reaction of silver nitrate with copper metal, metallic silver comes out of solution, and the solution turns blue. This as
aalyn [17]

Answer:

Single displacement reaction.

Explanation:

Hello!!

In this case, since the reaction between silver nitrate and copper metal is:

2AgNO_3(aq)+Cu(s)\rightarrow 2Ag(s)+Cu(NO_3)_2(aq)

As silver was forming silver nitrate, due to the presence of copper, which has the capacity to displace silver out of the salt, we notice the formation of solid silver and a resulting copper (II) nitrate which is blue in aqueous solution.

Therefore, this is a single displacement reaction, because the the lonely copper displaced the silver.

Best regards!

How many moles of CaO will be produced from 23.9 g of Ca?<br>2Ca(s) + O2(g) – 20:0(3)<br>mol​
inessss [21]

Answer:

0.6 moles of CaO will produced.

Explanation:

Given data:

Mass of calcium = 23.9 g

Moles of CaO produced = ?

Solution:

Chemical equation:

2Ca + O₂ → 2CaO

Number of moles of calcium:

Number of moles = mass/ molar mass

Number of moles = 23.9 g / 40 g/mol

Number of moles = 0.6 mol

Now we will compare the moles of calcium and CaO.

            Ca         :          CaO

              2          :          2

            0.6         :        0.6

 0.6 moles of CaO will produced.
