Answer:
Option A
Explanation:
The total heat absorbed during the chemical reaction is the total heat released by the surrounding.
Net change of heat is equal to zero
Hence, the energy liberated from the air or the walls of the containers would be equal to the energy absorbed by the chemical reactions is equal to 100 Kj
Thus, option A is correct
Scientists can bombard atomic nuclei with high-energy particles such as protons, neutrons, or alpha particles. Scientists synthesize a transuranium element by the artificial transmutation of a lighter element. ... It involves nuclear change, not chemical change. NOTE nuclear decay is a transmutation that happens naturally.
The family on the periodic table that has a filled outer
energy level is VIIIA. The answer is letter D. They are also called the noble
gases or inert gases. They are virtually unreactive towards other elements or
compounds. They are found in trace amounts in the atmosphere. Their elemental form
at room temperature is colorless, odorless and monatomic gases. They also have
full octet of eight valence electrons in their highest orbitals so they have a
very little tendency to gain or lose electrons to form ions or share electrons with
other elements in covalent bonds.
Answer:
Boiling is 212* Freezing is 32*
Explanation:
It simple facts
I believe that the choices for this question are:
C2H4O2, C4H8O4 CH2O, C6H12O6 C3H6O3, C6H12O6 C2H4O2, C6H12O6
The answer to this based on the molar masses given is:
C2H4O2, C6H12O6
To prove calculate the molar mass:
C2H4O2 = 2*12 + 4*1 + 2*16 = 60
C6H12O6 = 6*12 + 12*1 + 6*16 = 180
