Answer:
During a chemical reaction, the chemical species that are undergoing the transformation (or that are present in the starting) are called reactants, and the new species formed after the transformation are called the products.

Hope this is helpful! :)
Answer is:
3,94·10⁻² moles of silver chloride are contained in 244 ml of solution.
V(AgCl) =
244 ml = 0,244 l.
b(AgCl) =
0,135 mol/kg.
d(AgCl) =
1,22 g/ml.
m(AgCl) =
V(AgCl) · d(AgCl).
m(AgCl) = 244 ml · 1,22 g/ml.
m(solution AgCl) =
297,68 g.
m(AgCl) = 0,135 mol ·143,3 g/mol = 19,34 g.
ω = 19,34 g ÷ 19,34 g + 1000 g = 0,0189.
m(AgCl) = 0,0189 · 297,68 g = 5,64 g.
n(AgCl) = 5,64 g ÷ 143,3 g/mol = 0,0394 mol.
1) The unit in the question is $/pound.
2) The unit of the wanted information is pounds
According to the question;
1 pound of the fruit is sold at $1.99
x pounds of the fruit will be sold at $10.80 (remember that you are supposed to spend all the money in your pocket)
So;
x = 1 pound * $10.80/$1.99
x = 5.32 pounds of fruit.

Hello!</h2>
The answer is:
The approximate volume is 9.84 L.
<h2>
Why?</h2>
Since we are given the numer of moles, the temperature and the pressure of the gas, we can calculate the approximate volume using The Ideal Gas Law.
The Ideal Gas Law is based on Boyle's Law, Gay-Lussac's Law, Charles's Law, and Avogadro's Law, and it's described by the following equation:
Where,
P is the pressure of the gas.
V is the volume of the gas.
n is the number of moles of the gas.
T is the absolute temperature of the gas (Kelvin).
R is the ideal gas constant, which is equal to:
So, we are given the information:
Now, substituting the given information and isolating the Volume from The Ideal Gas Law equation, we have:
So, the approximate volume is 9.84 L.
Have a nice day!
How does the law of conservation of mass apply to this reaction: C2H4 + O2 → H2O + CO2?
