If too much of Na2Co3 is added to a particular chemical reaction, there will be a shortage of the other reactant which is supposed to react with the Na2Co3 and this will leads to excess production of the product. Stoichiometric should always be used to obtain information about the appropriate quantities of chemicals that should be used during chemical reactions.
I would think D, because of the larger amount of gas (25.0 L) than the needed (22.4 L) gas.
Answer:
Here's what I get.
Explanation:
An acid is a proton donor; a base is a proton acceptor.
Thus, HF is the acid and H₂O is the base.
The conjugate base is what's left after the acid has given up its proton.
The conjugate acid is what's formed when the base has accepted a proton.
HF/F⁻ make one conjugate acid/base pair, and H₂O/H₃O⁺ are the other conjugate acid/base pair.

Answer:
Synthesis
Explanation:
Reaction Given:
NH₃+ HCI ------> NH₄Cl
Type of reaction = ?
Solution:
Look at the reactants and products of the reaction to know the type of reaction
NH₃+ HCI ------> NH₄Cl
In this reaction two reactant combine and give 1 products.
Reactant of the reaction
NH₃ = Ammonia
HCl = Hydrochloric acid
Product of the reaction
NH₄Cl = Ammonium chloride
So,
That ammonia (NH₃) react with Hydrochloric acid (HCl) and produces salt.
in this reaction NH₃ is a week base and take a proton from HCl and form ammonium ion and Cl ion. these two ions in combine form gives a salt called ammonium chloride.
Type of Reaction:
This is type of synthesis reaction, in which NH₃ and HCl combine and form a new compound that is ammonium chloride salt (NH₄Cl). As the synthesis reaction is that reaction in which two are more compounds or molecules combine and form a new compound.
The Kj of heat that are needed to completely vaporize 1.30 moles of H2O if the heat of vaporization for water is 40.6 Kj/mole is calculated as below
Q(heat) = moles x heat of vaporization)
=1.30 mol x40.6 kj/mol= 52.78 Kj is needed
