Pls help, my assignment is to name alkalis around the home so far I have got toothpaste(bathroom), mouthwash (bathroom), indigestion tablets (bathroom), soap (bathroom & kitchen), bleach (kitchen), oven cleaner (kitchen). Can you help and think of anymore? Thanks
I would delete the bleach, it is not a true alkali unless other things have been added. What about drain opener chems? Your soap may not be an alkali...is is soap, or a detergent (beauty bar) bar...read the label.
Window cleaner contains ammonium hydroxide often.
baking soda?
How is Sedimentary rock form?
A 59-kg housepainter stands on a 13-kg aluminum platform. The platform is attached to a rope that passes through an overhead pulley, which allows the painter to raise herself and the platform. (Ignore the mass of the pulley and any friction in the pulley.)
To identify more alkalis around the home, you can consider the following:
1. Ammonia-based cleaning products: Many cleaning products, such as glass cleaners and multipurpose cleaners, contain ammonia, which is an alkali.
2. Dishwashing detergents: Some dishwashing detergents contain alkalis to help break down grease and food particles.
3. Antacid tablets: Besides indigestion tablets, there are various antacid tablets available, such as sodium bicarbonate tablets, which are alkalis used to neutralize stomach acid.
4. Hair relaxers and perms: Some hair products used for relaxing or perming hair contain alkalis like sodium hydroxide or ammonium thioglycolate.
5. Concrete cleaners: Concrete cleaners often contain strong alkalis like sodium hydroxide to remove stains and dirt.
6. Driveway and patio cleaners: Alkalis like potassium hydroxide are commonly found in outdoor cleaners used to remove dirt, grime, and moss from driveways and patios.
Regarding the formation of sedimentary rocks:
Sedimentary rocks are formed through a process called lithification, which involves the compaction and cementation of sediments. Here's a step-by-step explanation:
1. Weathering and erosion: Weathering breaks down rocks into smaller particles through various physical and chemical processes. Erosion then carries these particles, called sediments, away from the source rock.
2. Transportation: Sediments are transported by agents such as water, wind, or ice to new locations. During transportation, sediments can undergo sorting based on their size and weight.
3. Deposition: When the transporting agent loses energy, it can no longer carry the sediments and deposits them. These deposits form layers, known as strata, which build up over time.
4. Compaction: As more layers of sediment accumulate, the weight of the overlying sediments compresses the lower layers. This compaction forces out the air and water between the sediments.
5. Cementation: Pore spaces between sediments are filled with minerals like calcium carbonate, silica, or iron oxide. These minerals act as a glue, binding the sediments together and forming a solid rock.
Over millions of years, the accumulated layers undergo further compaction and cementation, resulting in the formation of sedimentary rocks like sandstone, shale, limestone, or conglomerate.
