Answer: A. 0.0375
Explanation:
To calculate the moles :
According to stoichiometry :
As 5 moles of 
give = 2 moles of 
Thus 0.094 moles of give =
of
Thus 0.0375 moles of will be produced when 3.00g of O₂ react completely
Answer:
Here's what I get
Explanation:
Ethylamine has an N atom with a lone pair of electrons.
It can act as a Brønsted-Lowry base and accept a proton from water and become an ethylammonium ion.
The structure of the ion is shown below (there is a C atom at each of the four-way bond intersections).
Answer:
the total density of the mixture = 3.415 x 10^3 g/mL
Explanation:
given:
density of a substance is 3.4 x 10^3 g/mL
Mixing it with another substance increases the density by 1.5 x 10^1 times.
find:
What is the density of the mixture?
-------------------------------------------------
let density (a) = 3.4 x 10^3 g/mL
density(b) = 1.5 x 10^1 g/mL
since there is no specific density provided for the mixture, we then add both to increase the density,
total density = density(a) + density(b)
total density = 3.4 x 10^3 g/mL + 1.5 x 10^1 g/mL
total density = 3.415 x 10^3 g/mL
therefore,
the total density of the mixture = 3.415 x 10^3 g/mL
Answer:
CuSO4(aq)
Explanation:
The aqueous for of CuSO₄ is an electrolyte and it will conduct electricity.
CuSO₄ is an ionic substance and in solid state, it will not have the ability to conduct electricity.
- In aqueous form, it will contain free mobile ions which serves as carriers of electric current.
- In the solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.
- The remaining given compounds will not conduct electricity as they are non-polar and do not have free mobile electrons.
