Answer:
2
Explanation:
because on the product side you have 2 sulfurs so you need 2 on the reactant side.
When two substances at different tempeartures como into contact, the substance that is at higher temperature will transfer energy, in the form of heat, to the substance that is at lower temperature, until their temperatures get equal.
In this case, if the two substances are isolated of the rest of the universe, the law of conservation of energy states tha the heat released by the substance initially at higher temperature is the same amount of heat gained by the substance originally at lower temperature.
Answer:
The correct answer -
a. Cd and Pb(NO3)2
b. Redox reactions
c. Pb and Cd(NO3)2
Explanation:
This is the reaction known as the redox or reduction-oxidation reaction of metals. In this particular reaction, there are two reactants Cadmium (III) in solid-state and lead (II) nitrate in the aqueous state. At the end of this reaction, the products that we get are lead (II) in solid-state and Cadmium (III) nitrate in the aqueous state.
cadmium (s)+ lead nitrate (aq) = lead (s) + cadmium nitrate (aq)
Cd (s) + Pb2+(aq) → Pb(s) + Cd2+(aq)
Here, Oxidizing agent is Pb2+ and the reducing agent is Cd.
There are two kinds of mixtures which are homogeneous and the heterogeneous. Homogeneous mixtures are mixtures that maintain the same uniform appearance and composition throughout; whereas, heterogeneous mixtures are mixtures that contain different visible substances or phases. Here are examples of each mixture.
Homogeneous mixtures: Rainwater, Air and Dishwashing detergent (This kind of mixture only shows one phase of matter)
Heterogeneous mixtures: cereals with milk, ice in soda and mixed nuts. (Obviously, this kind of mixture contains different phases of matter either in liquid, solid or gas).
