Select the correct answer. What is the number of protons in this carbon atom? A. 12 B. 6 C. 18 D. 24
andrew11 [14]

Answer:

The correct answer is

C. 6 Protons

Explanation:

Carbon is a nonmetallic element that is available in  both organic and inorganic compounds.

    Carbon belongs to group 14 elements in the periodic table,carbon is a chemical element with the symbol C and atomic number 6, it can  form long chains with its own atoms, a feature called catenation.

Two allotropes of carbon available are diamonds and graphites, which have different crystalline structures

The physical properties of carbon vary widely with the allotropic form.

examples are.

  1. Graphite, diamonds and coal are all nearly pure forms of carbon
  2. Diamond is highly transparent. Graphite is opaque and black
  3. Diamond is one of the hardest substances known to man. Graphite is soft and often used as the "lead" in lead pencils
  4. Diamond has a very low electrical conductivity. Graphite is a very good conductor
  5. Very brittle, and cannot be rolled into wires or pounded into sheets

What is the nucleotide sequence of an mrna strand that has been transcribed from the dna sequence ggtagc?
lys-0071 [83]

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.

To know more about the nucleotide sequence, refer:

A compound consists of 75% magnesium and 25% oxygen. Find the empirical formula.
laila [671]
<h2>Answer:</h2>

% Composition of elements:

  • Magnesium = 75%
  • Oxygen = 25%

Atomic mass of given elements:

  • Magnesium = 24 g
  • Oxygen = 16 g

Now, divide % composition by Atomic mass:

\footnotesize\implies Mg = \dfrac{\% \:  Composition}{Atomic  \: mass} =  \dfrac{75}{24}  =  \bf 3.125

\footnotesize\implies O = \dfrac{\% \:  Composition}{Atomic  \: mass} =  \dfrac{25}{16}  =  \bf 1.5625

Simplest Ratio:

\footnotesize\implies Mg  =  \dfrac{3.125}{1.5625}  = 2

\footnotesize\implies O  =  \dfrac{1.5625}{1.5625} = 1

Empirical Formula:

\footnotesize\implies \underline{ \boxed{ \red{ \bf Empirical \:  Formula = Mg_2O}}}

Which equation represents sublimation?
olga nikolaevna [1]

<span>Answer is </span>3) - H₂O(s) → H₂O(g)<span>

</span>Sublimation can be defined as the type of phase conversion of a substance which is in its solid phase to a gaseous phase without going through its liquid phase. <span>

According to the given choices only third one is correct because solid H</span><span>₂<span>O goes to its vapor without going liquid state. </span></span>
