If 0.34 moles of hydrogen reacts with excess chlorine, how many moles of product are formed?

Below is a list of terms used in characterizing solutions. Enter the correct term for each sentence. Note that not all of the te

AlladinOne [14]

Answer:

molality, mole fraction, solvent, solute, molarity.

Explanation:

The expression of concentration that provides the moles of solute per kilograms of solvent is molality.

$b=\frac{n_{solute}}{m_{solvent}(kg)}$

If you place 5 moles of sodium chloride and 4 moles of sucrose into 11 moles of water, the mole fraction of sodium chloride would be 0.25

$X(NaCl)=\frac{molesNaCl}{moles_{solution}} =\frac{5mol}{20mol} =0.25$

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the solvent is water.

The solvent is the component in major proportion and the one that defines the state of the solution.

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the solute is sodium chloride.

The solute is the component in minor proportion.

A way to express concentration that provides the moles of solute per liter of solution is molarity.

$M=\frac{n_{solute}}{V_{solution}(L)}$

When the products of a reaction have a lower enthalpy than the reactants___?

amid [387]

Answer:

The reactión is exothermic

Explanation:

The change in enthalpy follow the next equation:

ΔH = ΔH(products) - ΔH(reactants)

If the products have a lower enthalpy means that ΔH<0; this mean that the reaction gives heat to the environment

When solid Ni metal is put into an aqueous solution of Pb(NO3)2, solid Pb metal and a solution of Ni(NO3)2 result. Write the net

Sonja [21]

Answer:

$Pb^{2+}(aq)+Ni(s)\rightarrow Ni^{2+}(aq)+Pb(s)$

Explanation:

Hello there!

In this case, according to the given information, it turns out firstly necessary for us to write the complete molecular equation as shown below:

$Pb(NO_3)_2(aq)+Ni(s)\rightarrow Ni(NO_3)_2(aq)+Pb(s)$

Now, we can separate the nitrates in ions as they are aqueous to obtain:

$Pb^{2+}(aq)+2(NO_3)^-(aq)+Ni(s)\rightarrow Ni^{2+}(aq)+2(NO_3)^-(aq)+Pb(s)$

And then, we cancel out the nitrate ions as the spectator ones, for us to obtain the net ionic equation:

$Pb^{2+}(aq)+Ni(s)\rightarrow Ni^{2+}(aq)+Pb(s)$

Best regards!
