Answer:
0.504 mol Ag
Explanation:
First find the moles of copper in 16g
The molar mass of Cu is: 63.546
Therefore there are .252 moles in 16g as shown by this equation:
16/63.546 = .252
The mole ratio of Cu to Ag is 1 to 2
So we can simply multiply the moles of Cu by 2/1 to find the moles of Ag
We found .252 already so we multiply it by 2 and find that the reaction produces .504 moles of Ag
Answer:
option 1, 2, 3
Explanation:
Starch is present in plants and used for energy storage. It is a branched polypeptide and made of two units amylose and amylopectin.
Amylose is linear while amylopectin is branched. Monomer of starch is glucose and two glucose units are joined by aplha-1,4-glycosidic linkages.
Cellulose is a structural polypeptide and present in the cell wall of the plant. It is a linear polymer made of glucose. The two glucose units are joined by the β-glycosidic linkages.
Therefore, among the given, options 1, 2 and 3 are correct.
Answer:
Love for Music
Explanation:
This is one example of many non-physical traits. In the womb a mother can listen to her favorite music and the growing baby could grow to like it in the womb!
This is just one of the many other traits that could be passed to their offspring.
Hope this Helps!
I would go with D) is a community along with non-living components such as water and air
Answer:
Hydrogen bonding
Explanation:
The molecule of benzophenone (in the picture below) is polar because it has a bond of carbon and oxygen and these elements have huge differences of electronegativity, so they'll have partial charges: oxygen will be with negative partial charge because it has higher electronegativity (it attracts the electrons better).
The molecule of hexane (in the picture below) only has bonds between carbon and hydrogen which have close electronegativity, so the molecule is nonpolar. But, it can form an induced dipole, and the hydrogen will have a partial positive charge for a moment.
When these two molecules approach, the hydrogen and the oxygen must form a bond, which is called hydrogen bonding, and always occurs between hydrogen and an atom with high electronegativity (N, O, and F).
