You will need 75.0ml grams of potassium cyanide
To solve this, we need the Avogadros number to convert to
moles then multiply with molar mass to convert to mass in grams.
moles = 9.3 x 10^23 molecules * (1 mol / 6.022 x 10^23
molecules)
moles = 1.54 moles
Molar mass of NH3 is 17 g/mol:
mass = 1.54 moles * 17 g/mol
<span>mass = 26.25 g</span>
Answer:
See explaination
Explanation:
See attachment for the structure of the acetal that you would obtain by reaction of cyclopentanone with 1-propanol.
Answer:
1. a)
2. a)
3. b)
4. d)
Explanation:
The disposal method is how we throw away the wastes. In a chemical lab, the correct disposal method guarantees the security of the environment and the humans and animals that may be in contact with the materials.
So:
1. Excess chemical: Because it can be toxic, it may be disposed of in the appropriate waste container, which will depend on the characteristics of the material;
2. Reaction mixture: As the excess chemical, it can be toxic, so it must be disposed of at an appropriate waste container;
3. Used filter paper: Generally, the solids in the filter paper is not toxic, so it can be thrown away in the trash can;
4. Cracked or chipped beaker: Because the beaker is made of glass, it can cut when broken, so it must go to a broken glass box, that will protect the people that will deal with it.
Answer:
H20
Explanation:
H20, is water and this is an example of a molecule. Molecules are "atoms bonded together." And hydrogen and oxygen are bonded making it a molecule.
