Answer:
Calculated density = 0.8555g/ mL
Probable identity = Toulene
Explanation:
First off, the substance choices are;
isopropyl alcohol (density 0. 785 g/ mL)
toluene ( density 0.866g/ mL)
So upon calculation, if the density of the liquid substance is equal to either of the substances in the choice, it is that substance.
The relationship between density, mass and volume is given as;
Density = Mass / Volume
Mass = 38.5g
Volume = 45ml
Density = 38.5 / 45 = 0.8555g/ mL
Calculated density = 0.8555g/ mL
Among both substances, it is closest to toluene ( density 0.866g/ mL).
Probable identity = Toulene
Elastic-no loss of kinetic energy
inelastic-kinetic energy is changed to another kind of energy

<h2>A.EXACTLY CROSSING EARTH'S ORBIT OF THE SUN</h2>
To answer this question, you need to know the chemical equation for making glucose. It should be look like this
C6H12O6<span>(s) + 6O2(g) -->6CO2(g) + 6H2O(g)
In the equation, the amount of glucose (</span>C6H12O6) is 1 and the amount of oxygen(O2) is 6. But the equation ratio is using moles as a unit. A mole of glucose will weight 180g but a mole of oxygen weight 32g.
Then, the amount of oxygen forms would be: 6/1 * (15.90g/180g) * 32g= 16.96 grams
Answer:
Am I the bad guy for killing my fish, let me explain?
Explanation:
The fish said a bad word that was incredibly inappropriate, so then I told him to never say that again. He responds with, "No, I CAN SAY WHATEVER I WANT." After that I told him to not yell at me and then I killed him, remember he's a fish (GoldFISH).
