Answer:
You would weigh less on Uranus than on Earth because Uranus is far less mass-ive and dense than the Earth. This means that there is less gravity. Therefore, you would weigh less.
Explanation:
Even though Uranus is bigger, it is less massive; that is, there is less mass that makes up the planet. The volume of the planet might be larger, but the actual amount of mass isn't.
By the way, you couldn't stand on Uranus. It's made of gas!
Answer:
Contains DNA, Contains Ribosomes, Lacks a nucleus
Explanation:
Answer: option <span>C. the total energy inside the calorimeter will decrease.
</span>
Justification:
The answer is a direct application of the first law of thermodynamic (the law of conservation of energy).
By telling that the t<span>he calorimeter is sealed so that there is no heat exchanged between the contents of the container and the surrounding air, the first law of thermodynamics implies that the total energy inside the calorimeter will not change.
</span>
<span>That statement, without adding any more is enough justification.
</span>
Regarding, the other statements, you can show they are true:
<span>A.
the thermometer will show an increase in temperature.
</span><span>
</span><span>
</span><span>Since the reaction is exothermic, the heat released will increase the temperature inside the sealed calorimeter,which, of course, is shown by the termometer.

</span><span>B. The potential
energy of the products will be lower than that of the reactants.
</span><span>
</span><span>
</span><span>In any exothermic reaction, the potential energy of the products is lower than that of the reactants, because the heat released is lost by the reactants when they react and transform into the products.
</span><span>
</span><span>
</span><span>D. The water
increases in temperature as the reaction gives off heat</span>.
Sure. The heat cannot leave the sealed calorimeter, but the water inside the calorimeter will absorb that heat: the molecules of water will gain kinetic energy and so its temperature will be increase.
Answer:
1.225g
Explanation:
From the question given,
Volume of diamond = 0.35cm^3
Density of diamond = 3.5g/cm^3
Mass of diamond =?
Density = Mass /volume
Mass = Density x volume
Mass = 3.5 x 0.35
Mass of diamond = 1.225g
