q = mC∆T
q = (30.0g)(0.900J/goC)(50oC)
q = 1350 J
So, the right answer is 1350 J

Answer:
increase the rate of reaction.
Explanation:
Correct Answer: <span>(2) The mixture is homogeneous and cannot be separated by filtration.
Reason: Solution is said to be homogenous, if it contains single phase. In present case, salt and water, when dissolved in water forms a single phase. Hence, it is referred as homogenous solution. Also, individual components of homogenous system cannot be separated by the process of filtration. </span><span />
No, because boats and other mechanical vehicles can spill gas and oil into the freshwater. if the freshwater is scarce already, we should not contaminate it more by risking the gas and oil spills.
If the forces are equal and in opposite directions, the net force will equal zero.
Consider a tug-of-war team. If they are pulling with equal forces against each other, the red cloth on the rope will not move.
<em>F = ma
</em>
The cloth is not moving, so <em>a = </em>0 and the net force <em>F = </em>0.
