What is the percent yield if you experimentally produce 3.65 grams of copper when 1.87 grams of aluminum reacts with 9.65 grams of copper II sulfate?

What is the percent yield if you experimentally produce 3.65 grams of copper when 1.87 grams of aluminum reacts with 9.65 grams of copper II sulfate?

The \% yield when 4.65 g of copper is produced will be 70.4 \%.

How do you find the amount of substances produced in a chemical reaction?

A substance’s molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol). The molar mass constant can be used to convert mass to moles. By multiplying a given mass by the molar mass, the amount of moles of the substance can be calculated.

How many atoms are there in CuSO4?

21 atoms are present in compound cuso4.

What is the product of CuSO4 5H2O?

Copper sulfate pentahydrate | CuSO4. 5H2O – PubChem.

How do you calculate percent yield of copper?

(b) If 3.91 g of copper was actually obtained, calculate the percentage yield of the reaction.

  1. \% yield = 100 x actual yield / theoretical maximum yield.
  2. \% yield = 100 x 3.91 / 3.99.
  3. \% yield of Cu = 98.0\% (3 sf, 1 dp)

What is the percent yield if?

Percent yield is the percent ratio of actual yield to the theoretical yield. It is calculated to be the experimental yield divided by theoretical yield multiplied by 100\%. If the actual and theoretical yield ​are the same, the percent yield is 100\%.

How many substances are used in a chemical reaction?

Explain that in most chemical reactions, two or more substances, called reactants, interact to create different substances called products.

How many atoms does 1 mole of phosphorus molecule p4 contains?

4 atoms
1 mole of P4 = 6.023 x 1023 molecules of P4. 1 molecule of P4 = 4 atoms of P.

What happens when copper oxide reacts with sulphuric acid?

In this experiment, students react an insoluble metal oxide with a dilute acid to form a soluble salt. By reacting copper (II) oxide, a black solid, with colourless dilute sulfuric acid, they produce copper (II) sulfate with a characteristic blue colour.

What is the melting point of copper sulfate?

Cupric sulfate appears as a white or off-white solid. Melting point 200°C with decomposition. Non-combustible. Copper (II) sulfate is a metal sulfate compound having copper (2+) as the metal ion. It has a role as a sensitiser, a fertilizer and an emetic.

What is the ionic equation for copper(II) sulfate?

Net ionic equation: Zn (s) + Cu 2+ (aq) –> Cu (s) + Zn 2+ (aq) Since the copper (II) ion has substantially greater reduction potential (+0.15 V) than zinc ion (-0.76 V), it is readily reduced by zinc metal. The blue color of the aqueous copper (II) sulfate solution is due to the presence of the hexaaquacopper (II) ion in water.

What happens if you boil copper sulfate?

If the acid has not been hot enough, excess acid can co-exist with copper oxide. (Boiling off the water so that the copper sulfate appears and then decomposes with excessive heating is unsafe. The sulfur dioxide gases are toxic and can cause breathing difficulties.)
