Which element is most likely to replace hydrogen in a displacement reaction?
(1 point)
O lithium (Li)
O helium (He)
O bromine (Br)
O oxygen (O)
Answers
Answer: The correct option is (D) lithium (Li).
Explanation: Hydrogen is the element which belong to period 1. The atomic number of hydrogen is, 1
The electronic configuration of hydrogen is,
The number of valence electrons present in hydrogen is, 1.
(A) Helium is the element which belong to period 1. The atomic number of helium is, 2
The electronic configuration of helium is,
The number of valence electrons present in helium is, 2.
(B) Oxygen is the element which belong to period 2. The atomic number of oxygen is, 8
The electronic configuration of oxygen is,
The number of valence electrons present in oxygen is, 6.
(C) Nitrogen is the element which belong to period 2. The atomic number of nitrogen is, 7
The electronic configuration of nitrogen is,
The number of valence electrons present in nitrogen is, 5.
(D) Lithium is the element which belong to period 2. The atomic number of lithium is, 3
The electronic configuration of lithium is,
The number of valence electrons present in lithium is, 1.
From this we conclude that the lithium element has the same number of valence electrons as hydrogen.
Hence, the correct option is (D) lithium (Li).
The element that can be considered as a replacement for hydrogen in displacement reaction is lithium (Li)
Displacement reaction can be regarded as type of reaction whereby atom is been displaced by another atom in a molecule. Hydrogen has one valence electrons which is the same as the valence electrons in Lithium, and this implies that it can replace Hydrogen in a displacement reaction.Therefore, option A is correct.

A de-shelled egg is placed in tap water. The egg grows in size.
What is the best explanation for this change in size?
Water moved into the cell by osmosis because the solute concentration was higher inside the cell than outside the cell.
Water moved out of the cell by osmosis because the solute concentration was higher outside the cell than inside the cell.
Ions in the water moved into the cell through diffusion because there were more ions outside the cell than inside the cell.
Water moved into the cell by diffusion because there is more water inside the cell than outside the cell.
Answers
Answer:
Water moved into the cell by diffusion because there is more water inside the cell than outside the cell.
Explanation:
The de-shelled egg when placed in water swells because the concentration of water molecules outside the egg is much higher than the concentration of water molecules inside the egg, as a result of which endosmosis takes place and water from the beaker enters into the egg.

In Plants photosynthesis can only take place in the presence of sunlight during the day, respiration happens all day long, hence option c is correct.
What is respiration in plants?Plants' respiration is visible at night and day, plants consume oxygen during respiration while also releasing carbon dioxide. Both photosynthesis and respiration take place during the day.
However, only respiration takes place at night, which uses oxygen. A sequence of chemical processes known as cellular respiration converts glucose into ATP, which may then be utilized as energy for a variety of bodily functions.
Glycolysis, citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration.
Therefore photosynthesis takes place during the day but plants respire all the time, hence option c is correct.
