Answer:
A) Maltose
Explanation:
Maltose has the chemical formula of C12H22O11 which shows that it is composed of the elements carbon, hydrogen, and oxygen. Maltose also has carbon and hydrogen atoms in a 2:1 ratio.
Answer:
The equilibrium will remain at the same conditions because there is no effect and difference in the partial pressure which in turn affect the equilibrium state.
Explanation:
- As Nitrogen is an inert gas therefore it will not react with either the reactants or products.
- Also as the addition is being made by maintaining the volume of flask as constant, thus there will be no difference in the partial pressure of the individual components of the mixture by addition of the Nitrogen gas.
- An increase in pressure is observed but the effect is not aiding or retreating the equilibrium conditions
Answer:
atom
Explanation:
The sodium atom has a single valence electron that it can easily lose. (If the sodium atom loses its valence electron, it achieves the stable electron configuration of neon.) The chlorine atom has seven valence electrons and can easily gain one electron.
Answer:
We have to consume starch and cellulose in large amount in order to increase the consumption of polysaccharides which make our body healthier.
Explanation:
Starch is polysaccharide which is made up of many glucose molecules. it is mostly made in the body of plants and when we eat that plant this starch is transferred to our body and our body use it when it is needed while cellulose also made of hundred of glucose molecules but our body is unable to digest it because our body is unable to break the bonds between the monosaccharide of cellulose. It is good for humans due to the presence of high amount of fibers.
Answer:
Hg
Explanation:
We are given information about the unknown element, and using each characteristic, we can narrow down the possible elements until we have just one possibility left.
Conducts electricity: This means that the element has to be a metal, or a semi-metal, because non-metals cannot conduct electricity.
Forming chloride and oxide ions: When it is seen that it forms chloride and oxide ions in the form of XCl₂ and XO, it can be seen that this element has an ionic charge of +2. This narrows it down to the elements in <u>Group 2.</u>
Liquid at room temperature: This is tricky, because we realize that there are no elements in group 2 that are liquid at room temperature. So hence we can look at groups 3 to 12, and see if there are any liquid metals with an ionic charge of +2.
Taking all this information into account, we can see that the only element it can be is mercury (Hg).
