The answer is C guanine and thymine goes with adenine these pairs will always be the same a=t g=c
The correct option is B.
Carbon is an element with an atomic number of 6. Each atom of carbon is made up of electron, proton and neutron. Carbon has six protons and six neutrons in its atom but its number of neutrons differ. This is because carbon exhibit isotopy. The isotopes of carbon are: carbon 12, carbon 13 and carbon 14. Carbon 12 has 6 neutrons, carbon 13 has 7 neutrons and carbon 14 has 8 neutrons.
Answer:
7.85% of Hydrogen in the sample.
Explanation:
51/650 = .07846 x 100= 7.846% (round up)
Answer:
moon
Explanation:
the moon's gravitational pull generates tidal force which affects earth's tides
Answer:
The molecular equation for the reaction of CaCO₃ with CH₃COOH is:
CaCO₃ (s) + 2CH₃COOH (aq) → Ca(CH₃COO)₂ (aq) + H₂O (l) + CO₂ (g)
Option 1
Explanation:
CaCO₃ + 2CH₃COOH → Ca(CH₃COO)₂ + H₂O + CO₂
Option 3 is the same equation as option 1, but calcium acetate, does not precipitate, so the formed salt, is not a solid.
Option 2 and 4 are wrong because calcium acetate molecular formula is
Ca(CH₃COO)₂
Ca(CH₃COO)₂ → Ca²⁺ + 2 CH₃COO⁻
