The balanced chemical reaction will be:
C2H2 + 5/2O2 = 2CO2 + H2O
We are given the amount of C2H2 being burned. This will be our starting point.
64.0 g C2H2 (1 mol C2H2 / 26.02 g C2H2) (1 mol H2O/1mol C2H2) ( 18.02 g H2O/1mol H2O) = 44.32 g H2O.
Thus, the answer is 44.32 g H2O.
Answer:
Sodium chloride (NaCl)
Explanation:
According to Arrhenius, an acid is a substance that dissociates to give protons, whereas a base dissociates to give hydroxide ions in an aqueous solution.
Therefore, a chemical reaction in which an Arrhenius acid reacts with an Arrhenius base to give salt and water, is known as a Neutralization reaction.
For example: <u>Neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH)</u>
A strong acid, hydrochloric acid (HCl) reacts with a strong base, sodium hydroxide (NaOH) to give salt, sodium chloride (NaCl) and water (H₂O).
<em>The chemical equation for this Neutralization reaction:</em>
HCl (acid) + NaOH (Base) → NaCl (Salt) + H₂O (Water)
<u />
<u>Therefore, </u><u>sodium chloride (NaCl) is the salt formed</u><u> during the chemical reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH).</u>
Answer:
The pressure inside the container is 11 atm
Explanation:
We use the formula;
PV=nRT ---> P= nRT/V
P= 28 mol x 0,082 l atm/K mol x 215 K/45 L
<em>P=10,96977778 atm</em>
Answer:
D. 2.5 x 10 ^-14 Hz
Explanation:
Use wavelength formula: v = f x wavelength
Rearrange formula for frequency.
f = wavelength / v
f = 7.6 x 10 ^-6 / 3.00 x 10 ^8
f = 2.5 x 10^-14 Hz
Calculate the number of moles for each element. n=m/M Then compare, and which ever one is lowest is the limiting reactant because no more products can form without one or the other.
