Answer:
The Bronsted-Lowery acid is H2O
The Bronsted-Lowery base is CO3
The conjugate acid is HCO3
The conjugate base is OH
Explanation:
Molocules that lose a hydrogen in a reaction act as an acid, and those that recieve one act as a base.
6 Oxygen atoms
Explanation:
In the molecule 2(NO₃):
An atom is the smallest indivisible particle of any substance. They chemically combine to give compounds and molecules. Some of them are able to exist on their own.
An element is a substance that has a unique atom.
NO₃ has two elements: N and O
Number of atoms:
N = 1
O = 3
but we have two moles of NO₃
O = 3 x 2 = 6
N = 1 x 2 = 2

<h2>Hello!</h2>
The answer is: 4.77atm
<h2>Why?</h2>
Since there's a fixed volume, we can use the the Gay-Lussac's Law which stablish a relation between the pressure and the temperature:
<em>P</em> is the volume of the gas
<em>t</em> is the temperature of the gas
<em>k </em>is the proportionality constant
We also have the following equation:
Where:
We are asked to find the pressure in atm, so we must convert 483.73kPa to atm:
Then,
Have a nice day!
i think it’s B. a hydrocarbon reacts with oxygen
if i’m correct, a combustion reaction is anything that’ll give a reaction
Answer:
x = 4.5
4.5 moles of C2H6 is required to produce 13.5 moles of H2O
Explanation:
Given equation is :
2 C2H6 + 7 O2 → 4 CO2 + 6 H2O
if it requires 2 moles of C2H6 to produce 6 moles of H2O
then x moles of C2H6 is required to produce 13.5 moles of H2O
Using unitary method for solving, we get
x = 13.5 x 2 / 6
x = 13.5 / 3
x = 4.5
Therefore, 4.5 moles of C2H6 is required to produce 13.5 moles of H2O
