<u>Answer: </u>The net ionic equation for the following precipitation reaction will be 3Ca^{2+}(aq.)+2PO_4^{3-}(aq.)\rightarrow Ca_3(PO_4)_2(s)

<u>Explanation:</u>

Precipitation reaction is defined as the reaction in which two soluble salts combine in aqueous state to form one insoluble product known as a precipitate.

For the reaction of calcium chloride and potassium phosphate, the reaction follows:

3CaCl_2(aq.)+2K_3PO_4(aq.)\rightarrow Ca_3(PO_4)_2(s)+6KCl(aq.)

The ionic equation for the above reaction follows:

3Ca^{2+}(aq.)+6Cl^-(aq.)+6K^+(aq.)+2PO_4^{3-}(aq.)\rightarrow Ca_3PO_4(s)+6K^+(aq.)+6Cl^-(aq.)

To write the net ionic equation, spectator ions are not written because these ions lie on both the sides of the reaction and does not affect equilibrium. These ions are ignored in writing the net ionic equation.

Hence, the net ionic equation becomes:

3Ca^{2+}(aq.)+2PO_4^{3-}(aq.)\rightarrow Ca_3(PO_4)_2(s)

Which of the following statements is always TRUE for the freezing of water?
Rom4ik [11]

ΔG > 0 is always true for the freezing of water.

Explanation:

  • The freezing of water is only spontaneous when the temperature is fairly small. Over 273 K, the higher value of TΔS causes the sign of ΔG to be positive, and there is no freezing point.
  • The entropy decreases as water freezes. This does not infringe the Thermodynamics second law. The second law doesn't suggest entropy will never diminish anywhere.
  • Entropy will decline elsewhere, provided it increases by at least as much elsewhere.

What Is the ph of a solution where [h30+] =4.5x10-3
svetoff [14.1K]

pH is a scale used to measure the acidity or alkalinity of an aqueous solution. It can be used to calculate the amount of hydronium ions in the solution. It is expressed as the negative logarithm to the base 10 of the concentration.

A chemist determines by measurements that moles of nitrogen gas participate in a chemical reaction. Calculate the mass of nitrog
Likurg_2 [28]

Answer:

0.56 g

Explanation:

<em>A chemist determines by measurements that 0.020 moles of nitrogen gas participate in a chemical reaction. Calculate the mass of nitrogen gas that participates.</em>

Step 1: Given data

Moles of nitrogen gas (n): 0.020 mol

Step 2: Calculate the molar mass (M) of nitrogen gas

Molecular nitrogen is a gas formed by diatomic molecules, whose chemical formula is N₂. Its molar mass is:

M(N₂) = 2 × M(N) = 2 × 14.01 g/mol = 28.02 g/mol

Step 3: Calculate the mass (m) corresponding to 0 0.020 moles of nitrogen gas

We will use the following expression.

m = n × M

m = 0.020 mol × 28.02 g/mol

m = 0.56 g
