Answer:
b. aluminum
Explanation:
The specific heat capacity is defined as the amount of heat required to raise the temperature of 1g of a material in 1°C.
Thus, the sample with the higher specific heat capacity is the sample that will require more energy to increase its temperature in 1°C, suffering the smallest change in temperature.
Thus, is the aluminium with 0.900J/gK the element that is most likely to undergo the smallest change in temperature:
<h3>b. aluminum
</h3>
b) It is based on atomic properties as alkali metals requires 7 more electrons to complete their outer orbit. And they try to give those electrons to other elements to obtain noble gas configuration.
Noble gases are the gases which do not react easily with anything. They are also called as Inert gases, and belongs to group 18 of the periodic table.
Alkali metals are the substances which are found in Group I of a periodic table. Mostly the elements which are present are:
Properties of alkali metals are: Soft, shiny reactive metals. They are soft enough to cut with knife. Metals react with water and air quickly and gets tarnish, so pure metals are stored in container by dipping them in oil to prevent oxidation.

Answer:
The answer is
<h2>0.087 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of liquid = 2.6 g
volume = 30 mL
The density is
We have the final answer as
<h3>0.087 g/mL</h3>
Hope this helps you
Answer:
Mars is about 224.4 million kilometers from the Sun.
Explanation:
This statement is incorrect. The correct one is presented below:
<em>Mars is 1.5 AU from the Sun. About how many kilometers is Mars from the Sun?</em>
The Astronomical Unit (AU) is a length unit used in Astronomy to measure distances between planets of the Solar System and from the Sun whose units equals to 
. Since Mars is 1.5 AU from the Sun, we converting this value into kilometers by means of the following simple rule of three:
Mars is about 224.4 million kilometers from the Sun.
Answer:
D always different between different substances.
