PLS I NEED HELP ON NUMBER 4 Hydrogen chloride (HCl) is an acid called hydrochloric acid. It is extremely dangerous and proper safety equipment is required. Sodium hydroxide is a dangerous base. When sodium hydroxide reacts with hydrochloric acid, sodium chloride and water are produced. In addition, energy is released as a result of the reaction.

What type of chemical reaction has taken place?
Double Replacement and Neutralization Reaction

Is this reaction exothermic or endothermic?
Exothermic

Based on your answers to question 1 and 2, write the balanced chemical reaction.
NaOH+HCl= NaCl+H2O

4. At the conclusion of the reaction, there are 95 grams of products. How many grams of reactants must have been used?

i would say b

explanation:

but i think i would need more information than that

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

gas

explanation:

smoke is the matter of a gas
