Which of the following samples would be the most compressible?

Chemistry
1 answer:
Andrej [43]3 years ago
7 0

Answer:

CO2 (g)

Explanation:

In solids the interatomic or intermolecular space is least . It is most pronounced in gases . That is why inter molecular or interatomic attraction is least in gases . That is why gas flows .

Hence , when we try to compress a gas , due to inter molecular space , it is most likely to get compressed . It will be least compressed when we try to compress a solid because of lack of intermolecular space .

Plants use sunlight as energy to convert carbon dioxide and water into glucose and oxygen. Which best describes
masha68 [24]

Answer:

The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in  the  products

Explanation:

The expression that best describes this reaction is that the same amount of carbon will be found in the reactants as in the products.

During the process of photosynthesis, carbon dioxide combines with water using solar energy to produce glucose and oxygen.

It can expressed as depicted below:

       6CO₂  +  6H₂O  →  C₆H₁₂O₆  + 6O₂

To validate our choice;

 This is a balanced chemical equation:

        6 moles of carbon is found on the reactant side and also, 6 mole of carbon on the product side.

But Glucose is not found on both sides of the expression

The independent variable is the variable being changed. In this case, the independent variable is the calculators. The dependent variable is essentially what you are looking for that <u>depends</u> on the independent variable. In this case it would be time. The constant variable or controlled variable are something that doesn't change and would skew the results. One may be the exact same problem for both groups. Try to come up with two more.

What is the highest energy to which doubly ionized helium atoms (alpha particles) can be accelerated in a DC accelerator with 3
pentagon [3]

Answer:

Highest energy will be equal to 9.6\times 10^{-13}J

Explanation:

Charged on doubly ionized helium atom q=2e=2\times 1.6\times 10^{-19}C=3.2\times 10^{-19}C

It is accelerated with maximum voltage of 3 MV

So voltage V=3\times 10^6volt

Now energy is given by E=qV=3.2\times 10^{-19}\times 3\times 10^6=9.6\times 10^{-13}J

So highest energy will be equal to 9.6\times 10^{-13}J

An atom has the following electron configuration. 1s22s22p63s23p64s? How many valence electrons does this atom have? A: 2B: 3C:
Katena32 [7]

ANSWER

2 valence electrons

STEP-BY-STEP EXPLANATION:

The electronic configuration is given below as

1s^22s^22p^62s^23p^64s^2

Looking at the configuration, you will see that the last energy carries 2 electrons

Hence, the valence electrons are 2
