Soap acid + base
Sulphuric acid + soda + tallow
Railway grease + glycerine
You can use any base and acid to make soap. It can be used in many applications. It can be used to clean, as well as, it can be used as a lubricant. In the olden days when windows where made of wood people would used soap in the side sills to help the windows to slide easier, zippers that function badly use soap for lubricant to aid in function. To cleanse the pores of the skin salt and tallow will help improve skin softness, as well as make the pores smaller.

A breathing mixture used by deep-sea divers contains helium, oxygen, and carbon dioxide. what is the partial pressure of oxygen
pentagon [3]
Pressure of the Mixture = 101.4 kpa  
Pressure of the helium phe = 82.5 kpa 
 Pressure of CO2 pco2 = 0.4 kpa.
 Partial pressure of oxygen = Pressure of the Mixutre - (Pressure of the
helium + Pressure of CO2)
 Partial pressure of oxygen = 101.4 - 82.5 - 0.4
 Partial pressure of oxygen = 18.5 kPa

3 complete paragraphs on Static Electricity
Digiron [165]

Answer: Employments of friction based electricity incorporate contamination control, Xerox machines, and painting. They utilize the property that inverse electrical charges pull in. There are different utilizations including the properties of aversion and the making of electricity produced via friction flashes

friction based electricity is an awkwardness of electric charges inside or on the outside of a material. The charge stays until it can move away through an electric flow or electrical release.

In view of similar kinds of examinations like the one you performed, researchers had the option to set up three laws of electrical charges: Inverse charges pull in one another. Like charges repulse one another. Charged items pull in nonpartisan articles.

Draw the curved arrow mechanism for the formation of an acetal from acidic methanol and 4-methylpentan-2-one in the fewest steps
morpeh [17]

Answer:

See explanation below

Explanation:

This reaction is known as Ketone hydrolisis in acid medium. This involves the formation of an hemi cetal, and then, the acetal. This is often used to convert ketones or aldehydes in ethers.

The first step involves the reaction with the acid. The carbonile reacts with the acid and forms an alcohol there. The next step is the reaction of the alcohol, in this case, the methanol to form the hemi cetal. Then in the third step, we repeat the first step, using acid to turn the OH group into a great leaving group such water. Then the water leaves the molecule, leaving the space wide open in the next step for methanol, and the acetal is formed.

See picture for the curved arrow mechanism
