The answer is the option B. Nucleotide<span>. Nucleotides are organic molecules formed by three units :one or more phosphate groups, a sugar with five carbons (ribose or deoxyribose) and a nitrogenous base. Nucleotids are the units that form the two nucleic acid polymers: DNA and the RNA.</span>
68000 = 6.8 * 10000 = 6.8 * 10^4
hope this helps? c;
Answer:
D. Halogens
Explanation:
All elements in these groups have 7 valence electrons, meaning their electronegativity is the highest among the elements.
Based on the trend from the graph, the reaction time would have been 32.5 seconds.
<h3>What is the trend in the graph?</h3>
A trend is a general pattern which an observation follows based on previous observations and occurrences.
The reaction time is the time it take for a chemical reaction to occur.
Reaction time is also a measure of reaction rate. The shorter the reaction time, the faster the reaction rate and vice versa.
Based on the trend from the graph, the reaction time would have been 32.5 seconds.
In conclusion, reaction time is a measure of reaction rate.
