Is this the correct procedure for cleaning volumetric glassware prior to making a measurement: first, rinse with tap water. Seco
Bogdan [553]

The steps to be followed while cleaning volumetric glassware are:

1. Remnants from the previous measurements are wiped off with the help of paper towel.

2. The glassware is then soaked overnight in warm soap solution.

3. Then before rinsing with tap water, the glassware are scrubbed with an appropriate brush.

4. After scrubbing, the glassware is rinsed thoroughly with tap water in order to make sure there are no traces of soap solution.

5. The glassware is then rinsed with de-ionized water and finally with the solution that would be used for the volumetric measurement.

Stella [2.4K]

Answer:

Physical weathering is caused by purely mechanical changes to the rock, while chemical weathering is caused by chemical reactions.

Explanation:

Chemical weathering happens when the chemicals get diluted and dissolved in water and seep and percolate down the rock surfaces.

Physical weathering happens when rocks are fragmented into minor fragments while ensuring no alterations in their chemical makeup. The main causes behind physical weathering include spontaneous fluctuations in temperature like too high or too low heat or cold
