Shows that water is a compound...
made up of 2 hydrogen atoms and 1 oxygen atom...=H2O...
decomposition of water is by electrolysis which splits the compound!
hope this helps!
Answer:
Neutralization equation:
HCl + NaOH → NaCl + H₂O + Heat
Heat would calculated through,
Q = m . c. ΔT
Explanation:
When aqueous sodium hydroxide and hydrochloric acid react with each other a neutralization reaction occur. It produces water and salt. The salt would be sodium chloride.
Chemical equation:
HCl + NaOH → NaCl + H₂O + Heat
The heat produces can be calculated through the given formula.
Q = m . c. ΔT
Q = amount of heat produces
m = total mass of solution
ΔT = change in temperature of solution
C = specific heat capacity of solution
As the mostly solutions are water so we take the specific heat capacity of water which is 4.186 j/g .°C

Answer:
Change in molarity, temperature, volume/pressure depending on the conditions given
Explanation:
It really depends on the type of a reaction, however, we may apply general trends and see every possibility:
- if we increase the concentration of products, then, according to the principle of Le Chatelier, the equilibrium will shift toward the formation of products;
- if we have an endothermic reaction, increasing heat will lead a shift to the right and toward formation of products, since heat might be considered a reactant as well;
- if we have an exothermic reaction, removing heat/decreasing temperature will lead to an increase in products, as we're removing one of our products, heat, and system will try to rebuild the amount of heat lost forming the other products as a result as well;
- if we have gaseous substances in a reaction, an increase in pressure will shift the equilibrium to the right if we have a greater amount in moles of reactant gases compared to products, this is also known as a decrease in volume;
- if we have gaseous substances in a reaction, a decrease in pressure will shift the equilibrium to the right if we have a greater amount in moles of product gases compared to reactants, this is also known as an increase in volume.
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge.
Each element has a specific mass number and a specific atomic number. These two numbers are fixed for an element. The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. it has mass number 235 , it means that the sum of neutrons and protons in a carbon atom is 235.3
