Soaps are alkali , which is why they are bitter and slippery . Alkalis have a pH (potential hydrogen ) of 7-12 . Lemon juice is acidic which would neutralize the alkalinity of the soap . Acids have pH of 1-6 . It would cause the pH of the soap to drop .
FASFA4caster is the answer (D)
Answer is c. Natural gas.
Natural gas is a fossil fuel in liquid form that can be used as an energy source. It is found in subterranean reservoirs, often near oil deposits. It is non-renewable energy source. It takes very long time to renew. Natural gas is less pollutant as compared to coal and petroleum because when it's burned, it releases 25 % fewer greenhouse gases and pollutants. hydroelectric power, solar power and nuclear energy are renewable sources.
The correct answer is option A, that is, a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom.
Carbohydrates are the main source of diet, they provide energy to the body, mainly via glucose, a basic sugar, which is a part of the starch and an ingredient in various staple foods.
The carbohydrates can be signified by the stoichiometric formula, that is, (CH2O)n. It can be also be stated that the ratio of the carbon to hydrogen to oxygen is 1: 2: 1 in the molecules of carbohydrates. Carbohydrates are further categorized into three sub-kinds, that is, monosaccharides, disaccharides, and polysaccharides. The monosaccharides are the simple sugars, for example, glucose.
