serg [7]3 years ago
5 0

<u>Answer :</u>

Part 13:

The balanced chemical reaction will be:

Cu(NO_3)_2+Na_2SO_4\rightarrow CuSO_4+2NaNO_3

Part 14:

The balanced chemical reaction will be:

Cu(NO_3)_2+Na_2C_2O_4\rightarrow CuC_2O_4+2NaNO_3

Part 15:

The balanced chemical reaction will be:

Cu(NO_3)_2+2KOH\rightarrow Cu(OH)_2+2KNO_3

<u>Explanation :</u>

Balanced chemical reaction : It is defined as the reaction in which an individual element of an atom present on reactant side must be equal to product side.

Part 13:

The balanced chemical reaction will be:

Cu(NO_3)_2+Na_2SO_4\rightarrow CuSO_4+2NaNO_3

Part 14:

The balanced chemical reaction will be:

Cu(NO_3)_2+Na_2C_2O_4\rightarrow CuC_2O_4+2NaNO_3

Part 15:

The balanced chemical reaction will be:

Cu(NO_3)_2+2KOH\rightarrow Cu(OH)_2+2KNO_3

Argon gas has a boiling point of -197 °C. Which of the following diagrams best represents the
Paha777 [63]

Answer:

(a)

Explanation:

Hello,

In this case, the temperature required to boil argon, it means, transform it from liquid to gas is -197 °C. In such a way, since the temperature inside the steel sphere is -190 °C, which is greater than the boiling point, we realize argon is gaseous, therefore, the molecules will be spread inside the sphere as they will be moving based on the kinetic theory of gases.

For that reason, answer is scheme (a).

Best regards.

How many moles of MgSiO3 are in 237g of the compound?
Anna35 [415]
For this, we first calculate molecular weight of MgSiO₃:
Atomic masses:
Mg = 24
Si = 28
O = 16

Mr = 24 + 28 + 16 x 3
Mr = 100

moles = mass / Mr
moles = 237 / 100
moles = 2.37

Picture of gas laws question below:
Vera_Pavlovna [14]

Volume of the tank is 5.5 litres.

Explanation:

mass of the CO2 is given 8.6 grams

Pressure of the gas is 89 Kilopascal which is 0.8762 atm

Temperature of the gas is 29 degrees ( 0 degrees +273.5= K) so (29+273)

R = gas constant 0.0821 liter atmosphere per kelvin)

FROM THE IDEAL GAS LAW

PV=nRT ( P Pressure, V Volume, n is number of moles of gas, R gas constant, Temperature in Kelvin)

no of moles = mass/atomic mass

                    =  8.6/44

                    = 0.195 moles

now putting the values in equation

V=nRT/P

  = 0.195*0.0821*302/ 0.8762

  = 5.5 litres.

As the carbon dioxide gas occupies the volume os the tank hence volume of tank is 5.5 litres.
