The physical state of each reactant and product
Answer:
B) -1.00 M/min
Explanation:
Based on the reaction:
2 SO2(g) + O2(g) → 2SO3(g)
<em>2 moles of SO2 are consumed per mole of O2 producing 2 moles SO3</em>
<em />
In the problem, the sulfur dioxide has a rate of change of -2.00M/min. As the moles of oxygen that reacted are half the moles of SO2, its rate of change is halved, that is:
<h3>B) -1.00 M/min
</h3>
Answer:
1 It gives the cell its structure
2 It regulates the materials that enter and leaves the cell
Answer:
The answer is
<h2>0.2 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass of object = 20 g
volume = 100 mL
Substitute the values into the above formula and solve
That's
We have the final answer as
<h3>0.2 g/mL</h3>
