To get a result with the best degree of precision, the
number of significant figures should be equal to the smallest number of
significant figures of the given numbers. In this case, the smallest is 3 as
given by the number 9.03 mL.
Therefore density is:
<span>11.50 g / 9.03 mL = 1.27 g/mL</span>
Explanation:
We are given the following diagram.
In this diagram we can see how the energy in the reaction changes over time. The energy of the products is greater than the energy of the reactants. That means that the products have won some energy. That represents an endothermic reaction where the reactants absorb energy from the surrounding to form the products.
Answer: D. Endothermic reaction.
Answer:
Cannot withstand very high temperature as all plastics melt down very soon as compared to metals
The correct option is this: OXYGEN WILL HAVE MORE KINETIC ENERGY THAN NITROGEN.
Increasing the temperature of oxygen requires the application of heat. The heat energy that is applied to the gas will make the particles of the oxygen gas to gain more kinetic energy and to move more rapidly than before, by so doing, the particles will colloid more with one another and with the wall of the container. The kinetic energy of the particles of the nitrogen gas will remain the same since its temperature was not affected.
