Answer:
0.64 g O₂
Explanation:
I am assuming you meant 0.02 moles of O₂. In that case, convert moles to mass via stoichiometry:
0.02 mol O₂ x 32 g O₂/1 mol O₂ = 0.64 g O₂
Multiply the weight of the object by the distance it traveled to find the amount of work output. For the example: 10 lbs. x 1 foot = 10 foot-pounds. Find the work efficiency by dividing the work output by the work input and multiplying by 100.
Answer: Nail moving towards a magnet
Explanation: Since the iron nails and pins move towards the magnet, it means that the magnet exerts a force on them. The force exerted by a magnet is called magnetic force.
Cells need energy to carry out processes like mutation, reproduction and for mobility. The basic source of energy is glucose. If one factor prevents the cell from taking in the source of energy, then one possibility is the cell will weaken, unable to carry out processes and eventually will die.
Given are the steps in the titration process:
- Clean and rinse the burette with water
- Read and record the initial burette volume.
- Fill the burette with standardized base solution
- Rinse the burette with standardized base solution
The steps in the titration process is as follows:
1.) Clean and rinse the burette with water
2.) Rinse the burette with standardized base solution
3.) Fill the burette with standardized base solution
4.) Read and record the initial burette volume
