Answer: $SrCl_2(aq)+K_2CO_3(aq)\rightarrow 2KCl(aq)+SrCO_3(s)$

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.

The balanced chemical equation is:

$SrCl_2(aq)+K_2CO_3(aq)\rightarrow 2KCl(aq)+SrCO_3(s)$

For a particular reaction, Δ=−111.4 kJ and Δ=−25.0 J/K.

vichka [17]

Answer:

$\Delta G =-103.95kJ$

Explanation:

Hello there!

In this case, since the thermodynamic definition of the Gibbs free energy for a change process is:

$\Delta G =\Delta H-T\Delta S$

It is possible to plug in the given H, T and S with consistent units, to obtain the correct G as shown below:

$\Delta G =-111.4kJ-(298K)(-25.0\frac{J}{K}*\frac{1kJ}{1000J} )\\\\\Delta G =-103.95kJ$

Best regards!

A substance has a boiling point of 78 °C. Which of the following is true about the substance?

svetlana [45]

Answer:

When the substance is cooled, its temperature will fall below 78 °C after 100% of the vapor has changed to liquid.

Explanation:

Boiling point is the temperature at which a liquid changes state from liquid form to gaseous form without change in temperature. It may defined as the temperature at which the vapor pressure is equal to the pressure of the gas above the liquid.
A liquid with a boiling point of 78°C, it means that, when the liquid is heated, its temperature will start rising above 78 °C after 100% of the liquid has changed to vapors. Additionally, when the liquid is cooled, its temperature will fall below 78 °C after 100% of the vapor has changed to liquid.

K3PO4 + Al(NO3)3 → 3KNO3 + AlPO4 How many moles of potassium nitrate are produced when 2.5 moles of potassium phosphate react?

seraphim [82]

The ratio between K3PO4 and Al(NO3)3 is 1 : 1
We have 2 moles of each reactant so we have not a reactant in excess 

The ratio between K3PO4 and KNO3 is 1 : 3 
Moles KNO3 produced = 2 x 3 / 1 = 6
