The moon, man has not been to mars yet
H2O (water) has 2 hydrogen atoms and 1 oxygen atom.
1) C
2) B
3) A/B not sure
4) C I think
Your answer is C. Both gasoline and litter would need to be physically separated from the water, because neither bonds with the water.
To solve this question, you must use the formula: q=mc(change in temperature), where q is heat, m is mass, C is specific heat and temperature change is temperature change. The specific heat for ice is 2.1kJ/Kg x K (given). The change in temperature is 15 degrees Celsius (which you should change to kelvins so you can cancel out units), or 273 + 15 = 288K. The mass is 150 grams, which is 0.15 kg. Now, we can solve for q, heat. We will do this by substituting variables into the formula. After simplifying and cancelling out units, the answer we get is: 90.72kJ.
