Answer:
the study that deals with the structure of matter and how fundemantal constituets of the universe interact
The balanced chemical reaction would be as follows:
2H2O2 = 2H2O + O2
We are given the amount of the peroxide that decomposes. Using this as the starting point for the calculations, we can determine the amount of O2 produced. We do as follows:
14.3 mol H2O2 ( 1 mol O2 / 2 mol H2O2 ) = 7.15 mol O2 produced
(NH₄)₂CO₃ → 2NH₄⁺ + CO₃²⁻
k=2 k=1
Answer:
The atom will have a negative charge.
Explanation:
Electrons are subatomic particles with a negative charge, protons are subatomic particles with a negative charge, and neutrons have no charge. When a neutral atom's balance is disrupted by an extra electron, the atom becomes negatively charged.
Answer:
390
Explanation:
Specific heat capacity= heat/mass × temperature
Remember you convert gram into kilogram and 1 gram =0.001 kilogram
