Keep in mind that when two moles of potassium chlorate are decomposed, 3 moles of oxygen are produced.Think of the coefficients: since the mole ratio is 2 to 3, it means that<span> 2 mol KClO3 will turn into 3 mol O2.

2kclO3->2kcl+3O2
Answer:
Rubber, or another insulator.

Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek βρῶμος ("stench"), referring to its sharp and disagreeable smell.

When one desires to remove debris from the garden then a soil sifter can be used as a beneficial tool. Based on the needs, it can be of different kinds. A landscaper may sift soil that they use at the time of constructing gardens due to many reasons:
1. The soil becomes aerated, and thus, turn soft and easy to work upon.
2. Sifting the soil makes the work of withdrawing undesired substances from the soil easy.
3. It helps the plants to grow much better as the roots possess the tendency to penetrate more easily through the soil.
4. The soil becomes healthy due to shifting, thus, helps in producing a beautiful and healthy landscape.
