Answer:

The correct answer is option B, that is, they help scientists to understand the complex ideas and objects, which are not easy to handle.

Explanation:

The representations of the systems, objects, or events, which are used as tools for comprehending the natural world are known as scientific models. The models utilize known objects to signify unknown things. The models can assist one to visualize or develop pictures in the mind, for something, which is not easy to comprehend or observe.

Which of the following should have the largest Henry's law constant (kH) in water?XeCl2COCO2CH3CH3
geniusboy [140]

Answer:

CO

Explanation:

Henry's law constant reflects the solubility of a gas in water. The larger the kH, the more soluble is the gas. There is a rule that states that "like dissolves like", meaning polar is soluble in polar and nonpolar is soluble in nonpolar. Since water is polar, we have to consider the nature of these gases.

<em>Xe</em> nonpolar

<em>Cl₂</em> nonpolar

<em>CO</em> polar

<em>CO₂</em> nonpolar

<em>CH₃CH₃</em> nonpolar

CO is the only polar gas, so it has the largest kH.

Iron has a density of 7.9 space straight g divided by cm cubed. How much mass is in a 10 space cm cubed sample of iron? Question
dezoksy [38]

Answer:

79 g

Explanation:

Density (d) of iron = 7.9 g/cm³

Volume of the iron (V) = 10 cm³

Mass of the iron (m) = ?

Solution:

Formula will be used

                            d = m/V

As we have to find mass so rearrange the above equation

                              m = dV . . . . . . . . . . . (1)

Put values in above equation 1

                         m = 7.9 g/cm³ x 10cm³

                         m = 79 g

So,

mass of iron = 79 g

How does the number of valence electrons determine the type and number of bonds an element forms?​
Advocard [28]
The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. ... Nonmetals tend to attract additional valence electrons to form either ionic or covalent bonds.

Balance this equation. If a coefficient of "1" is required, choose "blank" for that box. ____CO +____ O2 → ____CO2
Black_prince [1.1K]
<h3><u>Answer;</u></h3>

2, Blank, 2 ;

<h3><u>Explanation;</u></h3>

The balanced chemical equation would be;

2 CO + O2 → 2 CO2

Balancing a chemical equation ensures that the number of atoms of each element are equal on both the reactants side and the products side. This ensures that the law of conservation of mass is obeyed in chemical reactions.

An ion with a -2 charge has? A) one missing protein B) two missing protons c) two missing electrons D) two extra electrons
Andreyy89

Answer:

D.

Explanation:

It would not be gain because it would say +6 instead of -2. Having a -2 charge means it wants to loose 2 electrons so it can form a full shell of 8 electrons. It wants to be inert (stable).

- Hope that helps! Please let me know if you need further explanation.
