For the volume of a solid or liquid
Density = mass/ volume so
volume = mass / density
For the volume of a liquid
Moles = volume x concentration
Volume = moles / concentration
For the volume of a gas
Volume = moles x 24
There are many other formulas as well :)
Answer:
Activity 1: Since the only forces apposing the upward movement of the load are gravity and air resistance the formulas of which can both be solved with weight then with constant variables for gravity and air, effort IS directly proportional to weight.
Activity 2:
Inclined plane.
to make lifting easier; raising or lowering a load.
Explanation:
hope this helps.
Answer:
Salicylic acids are clear white needle shaped crystal in room temperature and are used in pharmaceutical industries to produce analgesic.
Explanation:
- Salicylic acids are aromatic organic compound also known as monohydroxybenzoic acid which is lipophilic in nature.
- the physical properties are :
- they are colorlesss and odourless at room temperature.
- boiling point is 211°C and melting point is 315°C
- they are poorly soluble in water
- its saturated solution has pH of 2.4
- the chemical properties are:
- acytylation of hydroxy group in salicylic acid gives acytylsalicylic acid which is used as aspirin.
Answer:
Moles de LiOH= 0.33212 Moles
Explanation:
1 Mol of LiOH -->6.022*10^23 molecules of LiOH
therefore
The type of reaction that involved the transfer of electrons is oxidation-reduction
