Answer:
The positive charge in carbon is C
Explanation:
Atomic weight: An atom consists of protons, neutrons and electrons. Atomic mass is the sum of the number of protons and neutrons. The average weight of mass is called atomic mass of that atom.
The positive charge of an atom is proton.
The atomic weight of carbon = 12.0107 g/mol
Avogadro's number = 6.023×10⁻²³ atom/ mol
Charge = 1.602×10⁻¹⁹ C
The weight of carbon = 0.9 kg = 900 gram
Number of protons in carbon = 6
The positive charge in carbon is
=No. mole× Avogadro's Number× No. proton × charge per proton
C
Answer:
A copper cup with a mass of 100.0 g contains 96.0 g of water. Both. the cup and the water are at 13.0OC. If 70.0 g of a substance at 84.0OC is added to the cup, the temperature increases to 20.0OC. If the specific heat capacities of copper and water are exactly 390 and 4180 respectively, find the specific heat capacity of the substance.
