Answer:
call an vet ASAP 10 pounds of chocolate is very bad for a dog.
Explanation:
Chocolate is one of the worst things a dog can eat, and 10 pounds of it is worst! Take your dog to the vet IMMEDIATELY! I hope that that the dog will survive.

B.an acid-base neutralization reaction to produce oxygen gas
C.a displacement reaction involving two metals
D.a combustion reaction involving burning a metal in oxygen
In this reaction, reactant HgO decomposed into more than one products and reaction is called decomposition. Hg in HgO has oxidation number of +2 whereas oxidation number of Hg in product side is zero( zero because Hg is in its elemental form) so Hg is reduced. Hence option A is correct.
Decomposition can be defined as the “to break down” of complex substance or organic matter into a simpler inorganic matter.
It is one of the essential processes of the ecosystem, decomposition is a metabolic process which take up raw materials in the form of complex compounds, processing it and then converting it into simpler compounds.
some of the Bacteria, fungi and a few other microorganisms are involve in the process of decomposition as feed on dead organisms to survive.
in this process decaying and dead animals and plants serve as the raw materials undergo breakdown process and produces nutrients, carbon dioxide, and water; Microbes which involve in this process collectively known as saprophytes.

The products can weigh less than the reactants.
There is no loss of mass in the reaction.
a and b
Answer:
A. Some of the mass is converted to energy.
B.The products can weigh less than the reactants.
Explanation:
Nuclear reaction: A reaction in which a nuclei splits into two or more smaller nuclei of mass less than the reactants ,or two or more nuclei combined together to form heavy nuclei of mass less than the reactants and huge amount of energy released.
Nuclear reactions are of two types
1. Nuclear fission
2.Nuclear fusion
1. Nuclear fusion: A reaction in which two or more lighter nuclei combined together to form heavy nuclei of mass slightly less than the total mass of reactants and a large amount of energy released. Because the difference in mass of reactants and products change into energy .
2.Nuclear fission: A reaction in which a heavy nuclei splits into two or more lighter nuclei of total mass slightly less than the mass of reactant. Because the difference in mass of product and reactant change into energy therefore, a huge amount of energy released during this reaction.
Therefore, Option A and B are correct.
Answer : A. Some of the mass is converted to energy.
B.The products can weigh less than the reactants.
B. Current atomic models show an atom's positively-charged particles concentrated in the center of the atom.
C. Current atomic models show that atoms do not have negatively-charged particles.
(2) lose electrons and have an increase in oxidation number
(3) gain electrons and have a decrease in oxidation number
(4) gain electrons and have an increase in oxidation number
redox reactions deal with the transfer of electrons from one species to another species
redox reactions are made of reduction reactions and oxidation reactions
reduction reactions are when electrons take in electrons and results in a decrease in the oxidation number
oxidation reactions are when electrons give out electrons resulting in an increase in the oxidation number
therefore correct answer for reduction reactions are
(3) gain electrons and have a decrease in oxidation number
