Why are only some minerals found as native minerals? For example, iron and aluminum are almost never found as native elements in

nature.

Answer: Metals found as native minerals in nature are not highly reactive

Explanation:

Native minerals refers to minerals that are found in nature in their pure metallic form such as gold. Iron and aluminum are highly reactive metals. Highly reactive metals are far up in the activity series of metals, they have a great tendency towards oxidation. On the other hand, noble metals have less tendency towards oxidation and are found close to the bottom of the activity series for example, gold.

Gravity on Earth is 9.8 m/s2, and gravity on the Moon is 1.6 m/s2.
Ivanshal [37]

Answer:

Mass is the same but it weights 64 Newtons

Explanation:

First of Mass is the same in any sort of gravity. Now let's calculate weight

W = MG

where W = Weight

M = Mass

G = Gravity

W = (40kg)(1.6)

W = 64

Sorry for the spelling mistakes, hope this helps

Which member of the alkali metals has the highest
natulia [17]

Answer:

E)Li

Explanation:

Electronegativity is the tendency of an atom to attract a pair of bonding electrons. In the periodic table, electronegativity increases across the period and decrease down the group.

This means the element at the top of the group would have the highest electronegativity.

The correct option is;

E)Li

What happens to the partial pressure of oxygen in a sample of air if the temperature is increased? It increases. It decreases. I
Leno4ka [110]

The partial pressure of oxygen in a sample of air increases if the temperature is increased.

Answer: Option 1

<u>Explanation: </u>

According to Guy-Lussac's law, at constant volume, pressure exhibited by the gas molecules will be directly proportional to the temperature of the gas molecules. It is also known that pressure of mixture of gas molecules is the sum of partial pressure of each gas molecule in the mixture.

If the temperature increases, the partial pressure and the pressure of the mixture of gas also tend to increase. As it can be seen that at higher altitudes, the low temperature leads to the decrease in oxygen's partial pressure in the air.

So, it can also be concluded that temperature increases the oxygen's partial pressure in air increases.

Why is it better to conduct an experiment more than once?
lilavasa [31]

The first reason to repeat experiments is simply to verify results. Different science disciplines have different criteria for determining what good results are. Biological assays, for example must be done in at least triplicate to generate acceptable data. Science is built on the assumption that published experimental protocols are repeatable.


2)      The next reason to repeat experiments is to develop skills necessary to extend established methods and develop new experiments. “Practice make perfect” is true for the concert hall and the chemical laboratory.


3)      Refining experimental observations is another reason to repeat. Maybe you did not follow the progress of the reaction like you should have.


4)      Another reason to repeat experiments is to study and/or improve them in way. In the synthetic chemistry laboratory, for example, there is always a desire to improve the yield of a synthetic step. Will certain changes in the experimental conditions lead to a better yield? The only way to find out is to try it! The scientific method informs us that it is best to only make one change at a time.


5)  The final reason to repeat an extraction, chromatographic or synthetic protocol is to produce more of your target substance. This is sometimes referred to scale-up.
