1 ton = 2,000 pounds, so 1 ton would of course weigh more than 388 pounds
Answer:
The completed reaction is
CaCO3 + 2 HCl → (Ca+2 + 2 Cl-)aq + H2O + CO2↑
<h2>
Density of ethyl alcohol is 56.25 lbm/ft³ </h2>
Step-by-step explanation:
We have 1 lbm = 0.454 kg
1 kg = 2.203 lbm
1 m = 3.28 ft
Density of ethyl alcohol = 9.01 x 10² kg/m³
So
Density of ethyl alcohol = 56.25 lbm/ft³
I haven't done this in a while, but I'm pretty sure the answer is D, (-3, -1.)
If you were to substitute x for -3 and y for -1 in the first inequalities and simplify, it would look like this:
-1 > -3-2
-1 > - 5
And that inequality is true, because -1 is bigger than -5. Let's also substitute in the other inequality, which would be:
-1 > 2(-3) + 2
-1 > -6 + 2
-1 > -4
And -1 is bigger than -4. So, I think the answer would be D because substituting for those values of x and y would stil. make the inequalities true.
