Answer: give me more of an explaination
Explanation:
Baking soda has a ph of 9. any # that has less than 7 as a ph is acid, any number that has a ph of 7 is neutral, and any number with a ph greater than seven is a base. so baking soda is not an acid but a base.
Basically, this problem tells you to convert micrometers (μm) to millimeters (mm). The prefixes are used as hints for their values. Micrometer is 10⁻⁶ of a meter, while millimeter is 10⁻³ of a meter. If you use dimensional analysis,
(1.430×10⁻³ μm)*(10⁻⁶ m/1 μm)*(1 mm/10⁻³ m) = 1.43×10⁻⁶ mm
<h2>
Answer: Calcium Oxide and Calcium Hydroxide</h2>
Explanation:
To reduce the acidity of the soil, bases are used.
Calcium Oxide and Calcium Hydroxide are two such bases that are often used.
Answer:
Filtration, Sifting and Decanting
Explanation:
Heterogenous mixtures can be seperated by filtration and sifting (Also known as sieving). Sifting is the process of parting a mixture using a sieve. Sifting is used to separate solid mixtures that contain molecules of varying sizes. Filtration is the process of separating a liquid from an insoluble solid. A common example is using a funnel and a coffee filiter to seperate the liquide from the insoluable solid. Although there are many other methods for filtration. You can also separate mixtures by decantation. Decantation is the process of separating a liquid from a solid/liquid by removing the liquid layer at the top from the layer of solid/liquid below.
