Wear gloves when handling chemicals.

Make sure that none of the liquids near the Bunsen burner are flammable.

Explanation:

The safety precautions the student must apply while completing his experiment is that he/she must wear gloves while handling the chemicals and they must make sure that none of the liquids near the Bunsen burner are flammable.

  • Safety guidelines provides a detailed and careful way to carry out experiment and observations in the laboratory.
  • This is all in a bid to accidents in the workspace.
  • It is a good practices to wear gloves and laboratory coat while handling chemicals.
  • Also make sure to put out the Bunsen burner when not in use.
  • Keep papers and books away from the work area. Chemicals and papers are not friends.
  • Ensure that flammable liquids are not close to the Burner.

Decide whether a chemical reaction happens in either of the following situations. If a reaction does happen, write the chemical
sineoko [7]

Explanation:

A strip of solid palladium metal is put into a beaker of nicl2

Palladium (Pd) + Nickel Chloride (NiCl2)

To answer this question properly you must refer to the reactivity series.

The activity series is a chart of metals listed in order of declining relative reactivity. The top metals are more reactive than the metals on the bottom.

In this series, Nickel is higher than Palladium. This means that if a Palladium strip is placed into a solution of a Ni salt, then a reaction will not take place, nothing would happen.

Because Pd is lower than Ni in the reactivity series.

There is no reaction so no equation.

How do I do molarity equations?
ipn [44]
To calculate the molarity of a solution, you divide the moles of solute by the volume of the solution expressed in liters. Note that the volume is in liters of solution and not liters of solvent. When a molarity is reported, the unit is the symbol M and is read as “molar”.
I hope this helped :)

The coin of silver (ag) having 8.5 grams weight.calculate the number of moles of silver in coin
AfilCa [17]

0.0788 will be the number of moles of silver in coin.

<h3><u>How to find the number of moles?</u></h3>

A mole is the mass of a material made up of the same number of fundamental components. Atoms in a 12 gram example are identical to 12C. Depending on the material, the fundamental units may be molecules, atoms, or formula units.

A mole fraction shows how many chemical elements are present. The value of 6.023 x 10²³ is equivalent to one mole of any material (Avagadro's number). It can be used to quantify the chemical reaction's byproducts. The symbol for the unit is mol.

The number of moles formula is denoted by the following expression:

Number of moles = Mass of substance/mass of one mole
