Answer:
Explanation:
We know,
where Q is the reaction quotient and for this reaction, it is expressed as-
where species under third bracket represent concentrations in molarity.
T represents temperature in kelvin scale
Here T = 298 K
R = gas constant = 8.314 J/K
So,
or,
or,
Answer:
C) The same amount of energy
Explanation:
A bomb calorimeter is an equipment used to measure the amount of heat released or absorbed by a chemical reaction. This instrument is hermetic and has thermal insulation, which means that the system doesn't change heat with the surroundings.
So, by the difference of the temperature measured on the system (ΔT), the mass of a solution (m) and the specific heat of water (c) it's possible to calculate the heat in a reaction that occurs in aqueous solution, by the equation below:
Q = mxcxΔT
The heat, or the energy, of the reaction doesn't depend on where the reaction is happening, so the amount of energy measured on the bomb calorimeter will be the same in our body.
Answer:
168.56 mL
Explanation:
density = mass/volume, use basic algebra skills to replace the volume and solve
Answer:
A chemical equation is the symbolic representation of a chemical reaction.
Explanation:
Mass of ammonium sulfate = 660.7 g
<h3>Further explanation</h3>
Given
3.01 x 10²⁴ molecules of ammonium sulfate
Required
mass
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
mol ammonium sulfate (NH₄)₂SO₄ :
n = N : No
n = 3.01 x 10²⁴ : 6.02 x 10²³
n = 5
mass ammonium sulfate :
= mol x MW
= 5 x 132,14 g/mol
= 660.7 g
