Which one of these is an example of a physical change?

aleksklad [387]

Hey there!

The correct answer to your question is option A.

Sugar dissolving in warm water is an example of a physical change.
This is because sugar dissolving in the water does not create a substance or material. All of the other options are examples of chemical changes, because they eventually become a substance/material.

Hope this helps you.
Have a great day!

The empirical formula for trichloroisocyanuric acid, the active ingredient in many household bleaches is OCNCI. The molar mass o

TEA [102]

Answer:

These two are equivalent and valid:

$C_3Cl_3N_3O_3$

$Cl_3(CN)_3O_3$

Explanation:

The molecular superscripts for each atom in the molecular formula are determined by the number of times that the mass of the empirical formula is contained in the molar mass.

1. Determine the mass of the empirical formula:

$OCNCl$ :

Atomic masses:

O: 15.999g/mol
C: 12.011g/mol
N: 14.007g/mol
Cl: 35.453g/mol

Total mass:

15.999g/mol + 12.011g/mol + 14.007g/mol + 35.453g/mol = 77.470g/mol

2. Divide the molar mass by the mass of the empirical formula:

232.41g/mol / 77.470g/mol = 3

3. Multiply each superscript of the empirical formula by the previous quotient: 3

$O_3C_3N__3Cl_3$

Or:

$C_3Cl_3N_3O_3$

You might also write CN as a group:

$Cl_3(CN)_3O_3$
