Answer:
4C₈H₄OH + 35O₂ → 32CO₂ + 10H₂O
Explanation:
The unbalanced reaction expression is given as:
C₈H₄OH + O₂ → CO₂ + H₂O
To solve this problem, we use a mathematical approach.
aC₈H₄OH + bO₂ → cCO₂ + dH₂O
Conserving C: 8a = c
H: 5a = 2d
O: a + 2b = 2c + d
Let a = 1, c = 8, d = , b = 35
4C₈H₄OH + 35O₂ → 32CO₂ + 10H₂O
A scientist may repeat an experiment to make sure that results are reliable. An example would be if the test had a large variance in data gathered and no conclusions could be drawn.
Answer:
true
Explanation:
because Lewis represent valid resonance
Answer: 0.714 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of stock solution = 1.00 M
= volume of stock solution = 1.00 L
= molarity of dilute solution = ?
= volume of dilute solution = (1.00+0.40) L = 1.40 L
The concentration of a 1.00 M solution of sodium chloride (NaCl) after exactly one liter of the solution is mixed with 0.40 L of water is 0.714 M
If you have to make 36 grilled cheese sandwiches
you need to times 36 times 2
the ANWSER would be 72 :)
