A 6.13 g sample of an unknown salt (MM = 116.82g/mol) is dissolved in 150.00 g water in a coffee cup
calorimeter. Before placing the sample in the water, the
temperature of the salt and water is 23.72°C. After the
salt has completely dissolved, the temperature of the
solution is 28.54°C.


If 3.15 x 10J of heat was gained by the solution, what
is the total heat for the dissolution reaction of the 6.13 g
of salt?

Answers

According to law of conservation of energy, if 31.5 J of heat is gained than same amount of heat is lost .

What is law of conservation of energy?

According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1812.

Answer:

-3.19x10³ J

Explanation:

Since the surroundings absorbed 3.19 × 10³ J (or 3190 J) of heat, the system, or the dissolution reaction, must have lost the same amount of heat. The heat for the system, then, is -3.19 × 10³ J (or -3190 J). We know this is true because of the first law of thermodynamics, "heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy".

How many milliliters of a 70.0 ml solution of 1.51 m bacl2 must be used to make 12.0 ml of a solution that has a concentration of 0.300 m cl–?

Answers

1.43 \; \text{ml}

Explanation

  • Number of moles of chloride ions in the final solution: n = c \cdot V = 0.012 * 0.300 = 0.0036 \; \text{mol}
  • Each mole of barium chloride contains two moles of chloride ions. Thus the concentration of chloride ions in the initial 1.51 M barium chloride solution: \begin{array}{lll} c(\text{Cl}^(-)) &=& 2 * c(\text{BaCl}_2)\n& =& 2.52 \; \text{mol} \cdot \text{L}^(-1) \n & = &0.00252 \; \text{mol}\cdot \text{mL}^(-1) \end{array}

Therefore

\begin{array}{lll} V & = & n /c \n & = & 0.0036 / 0.00252\n & = & 1.43 \; \text{mL}\end{array}
