Answer:

3AgCl + Na₃PO₄ —> 3NaCl + Ag₃PO₄

The coefficients are 3, 1, 3, 1

Explanation:

From the question given above, the following data were:

Silver chloride reacts with sodium phosphate to yield sodium chloride and silver phosphate. This can be written as follow:

AgCl + Na₃PO₄ —> NaCl + Ag₃PO₄

The above equation can be balanced as follow:

AgCl + Na₃PO₄ —> NaCl + Ag₃PO₄

There are 3 atoms of Na on the left side and 1 atom on the right side. It can be balance by putting 3 in front of NaCl as shown below:

AgCl + Na₃PO₄ —> 3NaCl + Ag₃PO₄

There are 3 atoms of Cl on the right side and 1 atom on the left. It can be balance by putting 3 in front of AgCl as shown below:

3AgCl + Na₃PO₄ —> 3NaCl + Ag₃PO₄

Thus, the equation is balanced.

The coefficients are 3, 1, 3, 1

A 1.50 g piece of substance 8.52g was rolled out into a thin sheet measuring 24.0cm × 30.0cm

polet [3.4K]

Answer:

The volume of the sheet metal = 0.58 cm³

Note: The question is incomplete. A similar complete question is given below:

a 7.50 g piece of metal was rolled into a thin sheet measuring 24.0 cm × 30.0 cm

the density of the metal is 12.86 g/cm

calculate the volume of the sheet of metal

Explanation:

The mass of a substance is the quantity of matter present in that substance

The volume of a substance is amount of space the substance occupies

Density of a substance is the ratio of its mass and the volume it occupies. It is a measure of how compact a body is.

From definition above;

Density = mass/volume

Therefore, volume = mass/density

mass of thin sheet = 7.50 g

density = 12.86 g/cm³

Volume = 7.50 g / 12.86 gcm⁻³

Volume = 0.58 cm³

Therefore, the volume of the sheet metal = 0.58 cm³

Describe 3 methods to increase the rate of dissolution for sugar in a cup of tea

Xelga [282]

1. Stirring. This will agitate the sugar and encourage it to dissolve. Stirring creates friction and motion, which in turn will create heat that pulls the sugar particles apart as they are given energy.

2. Applying heat. As mentioned in the previous method. The application of heat gives extra energy to the sugar molecules which encourages it to pull apart and dissolve.

3. Increase the surface area. Where more sugar particles are fully submerged in the tea or being surrounded by the tea, the rate of dissolution will increase.

You are asked to devise a procedure for quality control in a fertilizer plant to check that the nitrogen and phosphorus content

romanna [79]

Answer:

Options : A, B and C are correct procedure for quality control in a fertilizer plant

Explanation:

The options that constitute the sampling plan are :

A) A 50 g sample is removed from every 100th bag of fertilizer produced, resulting in ten 50 g samples

B) Samples 1, 3, 5, 7, and 9 are thoroughly mixed and a 50 g sample of the mixture is removed

C) Samples2,4,6,8 and 10 and the 50 g sample from the mixture are taken to the analytical laboratory.

A quality control procedure is used to ensure that a certain product is produced following set standards or meets the required quality desired by the customer . and options A, B and C ensures that.
