1CuCl2 + 2Na(NO3) --> 1Cu(NO3)2 + 2NaCl

vivado [14]

Answer:

13.45 grams of NaCl will be produced

Explanation:

Given:

Mass of CuCl2 = 15 grams

Molar mass of CuCl2 = 134.5 g/mol

Mass of Na(NO3) = 20grams

Molar mass of Na(NO3) = 85 g/mol

To find:

Amount of Sodium chloride produced = ?

Solution:

No of moles of CuCl2 = 15/134.5 = 0.11 moles

No of moles of Na(NO3) = 20/85 = 0.23 moles,

1CuCl2 + 2Na(NO3) --> 1Cu(NO3)2 + 2NaCl

from the reaction, 1 mole of copper chloride reacts with 2 mole of NaNO3 to produce 2 moles of sodium chloride.

Hence, 0.11 mole of copper chloride will react with 0.23 mole of NaNO3 to produce 0.23 moles of sodium chloride.

Mass of 0.23 moles of NaCl = 0.23 × M.M of NaCl

(Molar mass of NaCl = 58.5)

Mass of 0.23 moles of NaCl = 0.23 × 58.5 = 13.45 grams

Convert the following temperature to kelvin:a) 113°C, the melting point of sulfur,b) 37°C, the normal body temperature,c) 357°C,

grandymaker [24]

The temperature to kelvin at 113°C is 386.15 K, at 37°C is 310.15 K and at 357°C is 630.15 K.

<h3>Equation :</h3>

To find Kelvin use formula,

Kelvin = 273.15 + degree Celsius

So,

(a) The melting point of sulfur at 113 degree Celsius

273.15 + 113 = 386.15 K

(b) The normal body temperature at 37 degree Celsius

273.15 + 37 = 310.15 K

(c) The boiling point of mercury at 357 degree Celsius

273.15 + 357 = 630.15 K

<h3>What is temperature?</h3>

Temperature is a measure of hotness and coldness that can be expressed on a variety of scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will flow from a hot body to a colder body to a lower temperature.

The total energy of the molecular motion inside the object is represented by the heat open object. Temperature is a measure of the thermal energy or average heat of a substance's molecules.
