It's 9.865 * 10^3 . The first number has to be between 1 and 10, and then multiply the number by ten, so it's 9.865 times 10 to the power of 3.
Answer: C
Explanation:
Put electron pairs about each atom such that there are 8 electrons around each atom (octet rule), with the exception of H, which is only surrounded by 2 electrons. Sometimes it's necessary to form double and triple bonds. Only C, N, O, P and S (rarely Cl) will form multiple bonds. Draw the Lewis dot structure for CF4.
CCAUCG is the nucleotide sequence of an mrna strand that has been transcribed from the dna sequence ggtagc.
<h3>
What is a nucleotide sequence?</h3>
- Transfer RNAs interact with the ribosome system to translate a nucleic acid sequence, known as a messenger RNA or mRNA, into the protein it encodes.
- Transfer RNAs partition the nucleic acid sequence into triplet codons, each of which specifies one amino acid, by binding to three nucleotides at once.
- The sequence does not contain punctuation signals to indicate which reading frame should be used, hence the nucleic acid can be read in three different phases or reading frames depending on the point at which division into codons begins.
- An addition or deletion in the nucleic acid sequence that changes the translation process from one reading frame to another is known as a frameshift mutation.

The empirical formula : Na₂Cr₂O₇
<h3>Further explanation</h3>
Given
170 g sample contains :
29.84 g sodium, 67.49 g chromium, and 72.67 g oxygen
Required
The compound's empirical formula
Solution
mol ratio of elements :
Na : 29.84 : 23 g/mol = 1.297
Cr : 67.49 : 51,9961 g/mol = 1.297
O : 72.67 : 16 g/mol = 4.54
Divide by 1.297
Na : Cr : O = 1 : 1 : 3.5 = 2 : 2 : 7
