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 :
Saturated hydrocarbon : 3-methyloctane, propane, heptane.
Unsaturated hydrocarbon : cyclopentene, heptyne
Explanation :
Saturated hydrocarbon : These are those hydrocarbons in which all carbon atoms and hydrogen atoms are bonded together with single bonds.
For example : Methane, Ethane, etc.
Unsaturated hydrocarbon : These are those hydrocarbons in which carbon-carbon atom bonded together with double or triple covalent bonds.
For example : Ethene, Butyne, etc.
Therefore, the saturated and unsaturated hydrocarbons are:
Saturated hydrocarbon : 3-methyloctane, propane, heptane.
Unsaturated hydrocarbon : cyclopentene, heptyne
Answer:
lower is write answer is am write
Answer : The correct option is C.
Explanation :
Enthalpy of reaction : It is defined as the changes in heat energy takes place when reactants go to products. It is denotes as 
.
= Energy of product - Energy of reactant
is positive when heat is absorbed and the reaction is endothermic.
is negative when heat is released and the reaction is exothermic.
In the given potential energy diagram, the energy of product at higher level and energy of reactant at lower level. The for this reaction will be positive.
So, the enthalpy of reaction is defined as the difference of the energy of the reactants and the energy of the products.
Covalent bonds form when electrons are shared between two nonmetals.
