Calculate the mass of NaCl in a 35-mL sample of a 1.3 M NaCl solution.

Chemistry
1 answer:
liraira [26]3 years ago

Answer:

= 2.659 g NaCl

Explanation:

Molarity of a substance is given by the formula;

Molarity = moles/Volume in liters

Thus;

Number of moles = Molarity ×  volume in liters

                              = 1.3 M × 0.035 L

                              = 0.0455 Moles

But, the molar mass of NaCl is 58.44 g/mol

The mass of NaCl is therefore;

     = 0.0455 g × 58.44 g/mol

     <u>= 2.659 g NaCl</u>

As the pendulum moves from point 2 to point 3, what happens to its mechanical energy?potential energy is converted to kinetic en
ahrayia [7]

Answer: Potential energy is converted to kinetic energy and back again.

Explanation:At points 1 and 3, the pendulum stops moving, and its mechanical energy is purely potential. At point 2, the pendulum is moving the fastest, and its mechanical energy is purely kinetic. Therefore, as the pendulum moves from point 1 to point 3, its potential energy is first converted to kinetic energy, then back to potential.

which of the following pairs of elements could react to form an ionic compound? A. potassium and calcium B. sulfur and oxygen C.
Grace [21]
The correct option is FLUORINE AND COPPER.
An ionic compound is usually formed by the combination of a metal and a non metal, the metal usually act as an electron donor while the non metal act as an electron acceptor. Thus, in ionic compounds, there is total transfer of electrons from the metal to the non metal. In the question given here, copper is the metal while the fluorine is the non metal.<span />
