Answer is: 588.15 <span>grams of ethanol.
</span>Chemical reaction: C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂.
m(C₆H₁₂O₆) = 1150 g.
n(C₆H₁₂O₆) = m(C₆H₁₂O₆) ÷ M(C₆H₁₂O₆).
n(C₆H₁₂O₆) = 1150 g ÷ 180.16 g/mol.
n(C₆H₁₂O₆) = 6.38 mol.
From chemical reaction: n(C₆H₁₂O₆) : n(C₂H₅OH) = 1 : 2.
n(C₂H₅OH) = 12.76 mol.
m(C₂H₅OH) = 12.76 mol · 46.07 g/mol.
m(C₂H₅OH) = 588.15 g.
Answer:
Technical program - cosmetologist
Nitrogen is diatomic which exists as N2. This is because of its small size and high electronegativity.
Phosphorus is tetra atomic which exists as P4.
Answer:
Coefficient: number balancing sulfuric acid in a chemical reaction.
Subscripts: number of atoms of each element forming the compound.
Explanation:
Hello!
In this case, since sulfuric acid is a molecule containing hydrogen, sulfur and oxygen in the following way:
- Two hydrogen atoms.
- One sulfur atom.
- Four oxygen atoms.
We can notice the 2 at H represents those two hydrogen atoms, the subscriptless S represent that 1 sulfur atom and the 4 at O represents those four oxygen atoms.
Moreover, since the molecules is given as 7 H2SO4
; from stoichiometry, we infer that every number preceding the molecule stands for a coefficient which is used to balance a undergoing chemical reaction reaction.
Best regards!
Answer:
The answer is
<h2>22 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of liquid = 44 g
volume = 2 mL
The density of the liquid is
We have the final answer as
<h3>22 g/mL</h3>
