1 carot = 0.2 grams
1.5 carot = 0.3 grams.
1 mol of Carbon = 12 grams
x mol = 0.3 grams
0.3 * 1 = 12 x
x = 0.3/12
x = 0.025 mol
1 mol of Carbon is 6.02 * 10^23 atoms
0.025 mol of carbon is x
1/0.025 = 6.02*10^23 * /x
x = 0.025 * 6.02 * 10^23
x = 1.5 * 10^22 atoms of carbon.
Answer: Radioisotopes are used by manufacturers as tracers to monitor fluid flow and filtration, detect leaks, and gauge engine wear and corrosion of process equipment. Small concentrations of short-lived isotopes can be detected whilst no residues remain in the environment.
Explanation: Uranium-235 is used for nuclear fission and as a fuel in nuclear reactors.
An isotope of cobalt is used in the treatment of cancer.
An isotope of iodine is used in the treatment of goiter.
Answer:
water and ethanol. hopefully
I would say that it's C. Seasonal temperatures have dipped over time, but I could easily be wrong, since it's my opinion. A weather condition is defined as the atmospheric conditions that 'comprise the state of the atmosphere in terms of temperature and wind and clouds and precipitation. But I believe it could just as easily be B. 150mm of rainfall is a normal average in the city.
Answer:
Cu(NO₃)₂ + 2NaOH → Cu(OH)₂ + 2NaNO₃
Explanation:
This is the reaction:
Cu(NO₃)₂ + 2NaOH → Cu(OH)₂ + 2NaNO₃
Let's verify the ions charges
Cu(NO₃)₂ → Cu²⁺ + 2NO₃⁻
NaOH → Na⁺ + OH⁻
Cu(OH)₂ → Cu²⁺ + 2OH⁻
NaNO₃ → Na⁺ + NO₃⁻
