The arrows in the chart below represent phase transitions. Three bars are shown labeled Solid, Liquid, and Gas. They are connect
tester [92]

Answer:

1,2,3

Explanation:

Heat gain implies that heat is absorbed by the system in order to make the stated phase transition possible.

Before a liquid changes to gas, intermolecular forces in the liquid are broken by energy supplied as heat.

Also, transition from solid to liquid requires energy to break intermolecular bonds.

Finally, sublimation requires input of energy in the form of heat.

7. How much ice is left over if 46 kJ of energy is added to 175 g of ice?
velikii [3]

Answer:

m_{leftover}=37g

Explanation:

Hello!

In this case, since the melting process involves the heat added to the system, the heat of fusion and the mass of water:

Q=m\Delta H_{fus}

Thus, as it has been reported that the heat of fusion of ice is 333.6 J/g, we can compute the melted mass of ice as shown below:

m=\frac{Q}{\Delta H_{fus}} =\frac{46000J}{333.6J/g}\\\\m=138g

Thus, the ice leftover results:

m_{leftover}=175g-138g\\\\m_{leftover}=37g

Regards!

What is the molarity of a 2.0 liter solution containing 58 grams of nacl?
Savatey [412]
First, need to know the formula of Molarity. 
                     moles of solute
  Molarity = ---------------------------
                      liters of solution

Given 
    2.0 liter of solution 
    58 grams of NaCl

Base of my research the moles of 58 grams of NaCl is 0.750 moles

Solution

                    0.750 moles
Molarity = -----------------------              = 0.375
                             2.0 L

The molarity of this solution is 0.375
