Answer:
Washing hands with soap and water. Sanitizers are only used if there is no soap and water.
The diagram best shows the magnetic field around the bar magnet is the diagram in option B.
<h3>What is the magnetic field?</h3>
The magnetic field refers to the region in space where the influence of a magnet can be felt. We know that strength of magnet can be seen by following the magnetic lines of force. The more the magnetic lines of force, the stronger the magnetic field especially when the line are packed closely together.
Looking at the diagrams of the magnetic lines of force, it must be recalled that the magnetic lines of force runs from the north pole to the south pole and not the other way round.
Thus, the diagram best shows the magnetic field around the bar magnet is the diagram in option B.

Answer:
A. Butyliodide will react faster than butylbromide, this is because iodide is a better leaving group in substitution reaction than bromide. B. 1-chloropentane is more reactive than 1-chloro2methylbutane, this is because Alkyl groups at the carbon atom decrease the reaction rate of SN2 reaction. C. Chloro- hexanechloride is more reactive than hexyl chloride because determining the rate of reaction in SN1 reaction of formation of carbocation is more stable than the primary one. SN1 reaction is a secondary carbocation reaction. D. Terri-butylbromide is more reactive than 1-bromo 2,2 dimethylpropane, this is because Tertiary carbocation is stable compared to the primary, this is because the rate of determining step involved in SN1 reaction. E. Sec-butyl bromide is more reactive than isobutylbromide, this is because Sec-butyl bromide belong to the secondary all halide why the other belongs to primary class. F. The reaction is faster in sodium methoxide in methanol than sodium acetate in acetic acid, this is because 1-chlorobutane is a primary alklyl- chloride than and the strength of nuclephile determines the rate of reaction. G. when sodium azide mixed with ethanol is used, the reaction will be faster, because strong acid form weak conjuage base and also azide is a better nuclephile.
Answer:
less than 5 centimeters because it is a nonvascular plant
Explanation:
Mosses are a group of plants under the division Bryophyta. They are said to be the most primitive plant life in existence as they lack true roots, stems and leaves. They also lack vascular system, hence, they are regarded as non-vascular plants. They usually grow in very small sizes (about 0.2 - 10cm).
According to this question, Penny bought a club moss plant for her water garden and needs to know how tall the plant will grow so she know how much space it will need. Since it is a miss plant that lacks vascular tissues i.e. nonvascular, it will likely grow less than 5 centimeters in height.
