Answer:
4.5 moles of H2O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
C2H5OH + 3O2 —> 2CO2 + 3H2O
From the balanced equation above,
1 moles of C2H5OH reacted to produce 3 moles of H2O.
Finally, we shall determine the number of mole of H2O produced by the reaction of 1.5 moles of C2H5OH. This can be obtained as follow:
From the balanced equation above,
1 moles of C2H5OH reacted to produce 3 moles of H2O.
Therefore, 1.5 moles of C2H5OH will react to produce = 1.5 × 3/ 1 = 4.5 moles of H2O.
Thus, 4.5 moles of H2O will be produced.
Answer:
4
Explanation:
How many neutrons in total were produced by the two
The answer would be bromine because electronegativity increases as you move up and to the right on the periodic table, and if you keep moving right you will see that bromine has the highest electronegativity out of those four elements.
Answer:
Explanation:
Given that,
The pH of a certain orange juice is 3.33.
We need to find the +ion concentration.
We know that,
So,
So, the +ion concentraion is equal to .
Answer:
The approximate molar mass of NaOH is 40 g/mol. You have 4 g NaOH.
No. of moles of NaOH is given by
n=(Given mass)/(Molar mass)
= 4/40 = 0.1 mol
1 mol has 6.022 × 10^23 molecules.
Thus, 0.1 mol has 6.022 × 10^23 × 0.1 molecules i.e. 6.022 × 10^22 molecules.
