Answer:
A solution, in science, refers to a type of mixture involving two or more substances. Specifically, the solution definition refers to a type of homogeneous mixture - i.e., a mixture that has a uniform composition and its individual components cannot be distinguished
The mass of substance which consists the equal number of particles as 12 grams of Carbon-12 is said to be mole.
For example:
The balanced chemical equation for production of water from hydrogen and oxygen is:

That means 2 moles of
reacts with 1 mole of
to give 2 moles of
.
The given formula is
.
Hence, 4 represents the number of moles in
formula that is 4 moles of
.
The number of atoms of sodium,
in
is:

The number of atoms of sulfur,
in
is:

The number of atoms of oxygen in,
in
is:

Step 1: Write Imbalance Equation
CH₃CHO + O₂ → CO₂ + H₂O
Step 2: Balance Carbon Atoms:
There are 2 carbon atoms at reactant side and one at product side. So multiply CO₂ with 2 to balance them. i.e.
CH₃CHO + O₂ → 2 CO₂ + H₂O
Step 3: Balance Hydrogen Atoms:
There are 4 hydrogen atoms at reactant side and 2 Hydrogen atoms at product side. So, multiply H₂O by 2 to balance Hydrogen on both sides. i.e.
CH₃CHO + O₂ → 2 CO₂ + 2 H₂O
Step 4: Balance Oxygen Atoms:
There are 3 Oxygen atoms at reactant side and 6 Oxygen atoms at product side. In order to balance them multiply O₂ on reactant side by 2.5 (5/2). i.e
CH₃CHO + 5/2 O₂ → 2 CO₂ + 2 H₂O
Step 6: Eliminate Fraction:
Multiply overall equation by 2 to eliminate fraction. i.e.
2 CH₃CHO + 5 O₂ → 4 CO₂ + 4 H₂O
Califactual. thsi is correct bcuz carbon takes 20 minutes to dissolve and ring making it a factual
Answer:
<h2>Density = 0.75 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 450 g
volume = 6.0 × 10² mL
Substitute the values into the above formula and solve for the density
That's

We have the final answer as
<h3>Density = 0.75 g/mL</h3>
Hope this helps you
