Answer:
2.33 mol C
Explanation:
Step 1: Write the balanced generic chemical equation
3 A ⟶ C + 4 D
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of A to C is 3:1.
Step 3: Calculate the number of moles of C produced from 7 moles of A
We will use the previously established molar ratio.
7 mol A × 1 mol C/3 mol A = 2.33 mol C
Here is a universal law to balance chemical equations :
All chemical equations must be balanced
because of the law of conservation of mass.
It states that "matter
cannot be created or destroyed."
So, the number of atoms that you
start with at the beginning of the reaction must equal the number
of atoms that you end up with.
keeping this law in our mind,lets balance the<span> equation for the reaction of benzene and hydrogen to form cyclohexane.
</span><span>C 6 H 6 + H 2 → C 6 H 12.
Here is the balance chemical equation.
</span><span>2 C 6 H 6 + 6 H 2 → 2 C 6 H 12.</span>
Answer:
sodium chloride—is NaCl.
Explanation:
Table salt is an ionic compound, which breaks into its component ions or dissociates in water. These ions are Na+ and Cl-. The sodium and chlorine atoms are present in equal amounts (1:1 ratio), arranged to form a cubic crystal lattice.

2. In naming compounds
3. To work out reacting proportions in titration reactions
Answer: 5.74×10^8 stacks
Explanation:
The U.S. quarter has a mass of 5.67 g and is approximately 1.55 mm thick.
1 stack would contain $2.83x 10^4
No. of stacks to pay off debt=
$16,213,166,914,811/2.83 ×10^4
= 5.74 × 10^8 stacks
