Copper chloride ...............
Answer:
The answer is B. A hydrogen atom forms a convalent bond.........
The correct answer is + 32.5 J because heat is absorbed here by copper not evolved also after calculation we will find the H value is positive, lets calculate it:
H = m C Δt where:
m = 10 g
C = 0.13 J/g.°C
Δ t = final temperature - initial temperature = 50 - 25 = + 25 °C
so H = 10 x 0.13 x (+25) = + 32.5 J
Answer:
Organic Material
Explanation:
Carbon Dating is the process in which the age of a piece of organic matter is determined by the proportions of carbon isotopes it contains.
Answer:
The different forms of an element based on the number of neutrons in the nucleus are called "isotopes." Carbon-12 is only one isotope of the element carbon, with 6 protons and 6 neutrons. There are also carbon-13, with 6 protons and 7 neutrons, and carbon-14, with 6 protons and 8 neutrons.
