Liquid and gases is the two general types of air pollution
The slope would be 8.92g/cm^3.
<em>D = m/V</em>
<em>m = DV
</em>
The equation for a straight line is
<em>y</em> = m<em>x</em> +b, where m is the slope and b is the y-intercept. We have
<em>m</em> = D<em>V</em> + 0
Thus, a plot of <em>m</em> vs <em>V</em> will give a straight line with a slope of <em>D</em> and a
<em>y</em>-intercept at the origin.
Slope = <em>D</em> = 8.92g/cm^3
Answer:
First step would be convert to moles
Final Answer: 37.8 g of NaCl
Explanation:
The reaction is:
2Na + Cl₂ → 2NaCI
We convert the mass of each reactant to moles:
18 g . 1mol /23g = 0.783 moles of Na
23g . 1mol / 70.9g = 0.324 moles of chlorine
We use the mole ratio to determine the limiting reactant:
Ratio is 2:1. 2 moles of Na react to 1 mol of chlorine
Then, 0.783 moles of Na, may react to (0.783 . 1)/2 = 0.391 moles.
Excellent!. We need 0.391 moles of Cl₂ and we only have 0.324 moles available. That's why the Cl₂ is our limiting reactant.
We use the mole ratio again, with the product side. (1:2)
1 mol of Cl₂ can produce 2 moles of NaCl
Then, our 0.324 moles of gas, may produce (0.324 . 2)/1 = 0.648 moles
Finally, we convert the moles to grams:
0.648 mol . 58.45g/mol =
