Answer: Image result for What does Boyle's Law describe?

This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant.

Explanation:

The term mole concept is used here to determine the moles of ammonia. The number of moles of ammonia which can be make from 6.20 moles of N₂ is 12.4.

One mole of a substance is defined as that quantity of it which contains as many entities as there are atoms exactly in 12 g of carbon - 12. The formula used to calculate the number of moles is:

Number of moles = Given mass / Molar mass

You need one nitrogen atom to produce ammonia. Here we can see that there are two nitrogen atoms in N₂.

One mole of any substance contains Avogadro number of molecules. A mole is defined as the mass of the substance which consists of the equal quantity of basic units.

The number of moles of ammonia from 6.20 moles of N₂ is:

6.20 × 2 = 12.4

Thus the number of moles is 12.4.

Answer:

1. Insulin

2. Keratin

Explanation:

Proteins are one of the four biological molecules found in living systems. They are polymeric molecules made up of monomeric units called AMINO ACIDS. Proteins perform a wide variety of functions in the body ranging from enzymatic functions to structural roles.

Two examples of proteins found in the body are keratin, insulin. Keratin is a structural protein located in the skin, hair and nails while insulin is an enzymatic protein that aids in digestion.

Answer:

Explanation:Well most scientists used microscopes but they also looked at bigger ones so the answer would be “by running experiments that expose there properties”

Answer:

When light is shone on to the surface of a metal, its electrons absorb small amounts of energy and become excited into one of its many empty orbitals. The electrons immediately fall back down to lower energy levels and emit light. This process is responsible for the high luster of metals.

Answer:

The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.

Explanation:

On the periodic table, a group refers to a vertical column of elements that share similar chemical properties.

For the main groups, the characteristic do the elements have in common is valence electron configuration and chemical reactivity.

On the periodic table, a group refers to a vertical column of elements that share similar chemical properties. These elements are arranged in such a way that they have the same number of valence electrons, which are the electrons in the outermost energy level (shell) of their atoms. The number of valence electrons is a critical factor in determining the chemical behavior and reactivity of elements, as it governs their ability to form chemical bonds with other elements.

Main group elements, also known as representative elements, are located in the s-block and p-block of the periodic table. These elements are found in Groups 1, 2, and 13 to 18. Each main group is labeled with a number from 1 to 18.

Here are the main characteristics that elements in the same main group (vertical column) have in common:

1. Valence Electron Configuration: Elements in the same main group have identical valence electron configurations. For example, elements in Group 1 (alkali metals) all have one valence electron in their outermost energy level (ns¹), while elements in Group 18 (noble gases) have a full outermost energy level.

2. Chemical Reactivity: Due to their identical valence electron configuration, elements in the same group show similar chemical reactivity. They tend to form similar types of chemical bonds and react similarly with other elements to achieve a more stable electron configuration.

3. Periodic Trends: Main group elements within a group exhibit predictable trends in their physical and chemical properties as you move from the top to the bottom of the group. For example, the atomic radius tends to increase, ionization energy tends to decrease, and metallic character tends to increase as you go down a group.

Explanation:

Trust me please

Answer:

V = 0.0496 L

Explanation:

Given that,

The mass of a sample, m = 352.2 g

The density pf sample, d = 7.10 g/mL

We need to find the volume of the sample. We know that the density of an object is given by :

[tex]d=\dfrac{m}{V}\\\\V=\dfrac{m}{d}\\\\V=\dfrac{352.2}{7.1}\\\\V=49.6\ mL[/tex]

or

V = 0.0496 L

So, the volume of the sample is 0.0496 L.

Answer:

C

i) 2 C(s) + O2(g) → 2 CO

ii) Carbon monoxide poisoning occurs when carbon monoxide builds up in your bloodstream. When too much carbon monoxide is in the air, your body replaces the oxygen in your red blood cells with carbon monoxide. This can lead to serious tissue damage, or even death.

D

The iron oxide gets reduced.

The carbon gets oxidised.

E

the reason is that aluminium is more reactive than carbon to be extracted in a blast furnance.an element lying lower in the metal reactivity series can be reduced by carbon (a reducing agent) but aluminum lies above carbon metal series.

F

i) electrolysis.

ii) It is soft and malleable. Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts. This is because of its particular properties.
