Answer:
The given equation obey the law of conservation of mass.
Explanation:
Chemical equation:
2LiOH + CO₂ → Li₂CO₃ + H₂O
There are equal number of atoms of oxygen, hydrogen and lithium on both side of equation so it obey the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
2LiOH + CO₂ → Li₂CO₃ + H₂O
2(6.941 + 16 + 1) + 12+32 6.941×2 + 12 + 3×16 + 18
47.882 + 44 13.882 +12+48 + 18
91.882 g 91.882 g
The mass of reactants and product are equal.
Answer:
A polysaccharide (n) can be formed by linking several monosaccharides through glycosidic linkages.
Explanation:
Polysaccharides are carbohydrates or complex carbohydrates, where monosaccharides join with glucosidic bonds to form a more complex structure that would be the polysaccharide.
An example of a polysaccharide is starch, or glycogen.
Starch is found in many foods such as potatoes or rice, and glycogen is a form of energy reserve of our organism housed in muscles and liver to fulfill locomotion, physical activity, and other activities that consist of glycolysis.
Polysaccharides are degraded in our body by different stages, and several enzymes unlike monosoccharides or disaccharides, since they have more unions and a more complex structure to disarm in our body and thus assimilate it.
Polysaccharides are also part of animal structures, such as insect shells or nutritional sources, among others.
Answer: hydroxide ions
Explanation:
According to the Arrhenius concept, an acid is a substance that ionizes in the water to give hydronium ion or hydrogen ion and a bases is a substance that ionizes in the water to give hydroxide ion .
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
As KOH can give hydroxide ions on dissociation , it is considered as arrhenius base.
Answer: F. Electron pair acceptor
Explanation:
A Lewis acid can be properly defined as any substance such as H+ (hygrogen ion) that can accept a pair of electron.
While a Lewis base is any substance such as (OH-) that can donate a pair of electron.
In the neutralization reaction between an acid ( H+ ) and a base (OH-). Hydrogen ion (H+ ) is the Lewis acid because it accepts an electron pair from (OH-).
Other examples of Lewis acid are; Mg2+, K+
