Answer:
There is no attachment to this question, however, the base sequence on the model built by the student is: CAGCCATC
The options of the bases on the complementary model are:
A) CTACCGAC
B) GUCGGUAG
C) GTCGGAAG
D) GTCGGTAG
The answer is D
Explanation:
A DNA molecule is a polymer biomolecule made up of nucleotide bases. It is a double stranded molecule, with each strand containing nucleotides held together by hydrogen bonds. The pairing of nucleotides in one strand of DNA to another follows the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine binds to Thymine (A-T) while Guanine binds to Cytosine (G-C).
According to this question, a student builds a model containing the base sequence: CAGCCATC, the model that contains bases that are complementary to the ones built by the student is: GTCGGTAG
Answer:
The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles.
Explanation:
Answer:
1) CO₂
2) 0.2551 g
Explanation:
The balanced reactions are:
CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂
MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂
1) The gas produced is CO₂.
2) Calculate mass of CaCO₃:
(0.5236 g) (0.4230) = 0.2215 g CaCO₃
Convert to moles:
(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃
Find moles of CaCO₃:
(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂
Convert to mass:
(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂
Calculate mass of MgCO₃:
(0.5236 g) (0.5770) = 0.3021 g MgCO₃
Convert to moles:
(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃
Find moles of MgCO₃:
(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂
Convert to mass:
(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂
Total mass of CO₂:
0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂
