Answer: iron

Explanation: Metals' atoms are closely bonded in a crystal lattice. In metallic bonds, the electron cloud boundaries of atoms touch each other. Many nonmetals occur as diatomic molecules. The electron clouds of these two bonded nonmetal atoms overlap .

Hydrogen atoms are most likely to touch each other without overlapping because of their small size and simple atomic structure.

A hydrogen molecule is a particle of the synthetic component hydrogen. The electrically unbiased molecule contains a solitary emphatically charged proton and a solitary adversely charged electron bound to the core by the Coulomb force. Nuclear hydrogen is around 75% of the baryonic mass of the universe.

Hydrogen exist as diatomic particle, I.e., it can exist by attaching to another hydrogen. You realize that hydrogen has just a single electron in it's furthest and just shell. Yet, to accomplish a steady design, there should be two electrons in this shell. So two hydrogen molecules share their electrons by holding.

Answer:

C. A Spring Scale

Explanation:

Using process of elimination, we can quickly decide that a stopwatch and a ruler will not be useful in measuring the force. This leaves us with either the spring scale or a balance scale. A balance scale is used to compare two weights, so this is eliminated. That leaves us with a spring scale. This is because we can attached the spring scale to the car and when we let it go, we can record the force. I hope this helps!

Answer:

628.520 mmHg

Explanation:

1 atm = 760 mmHg

[tex](760 \div 1) \times 0.827[/tex]

The pressure of 0.827 atm in mmHg is 628.52 mmHg

Pressure has various units of measurement such as atmosphere (atm), pascal, mmHg, Newton per square metre (N/m²) etc. These units can be converted from one to the other.

Considering the question given above, we can convert 0.827 atm to mmHg as illustrated below:

1 atm = 760 mmHg

Therefore,

0.827 atm = 0.827 × 760

0.827 atm = 628.52 mmHg

Thus, 0.827 atm is equivalent to 628.52 mmHg

In the Northern Hemisphere, winter generally begins on December 21 or 22. This is the winter solstice, the day of the year with the shortest period of daylight. Summer begins on June 20 or 21, the summer solstice, which has the most daylight of any day in the year.

The component that would be the solvent from the graph would be nitrogen.

From the graph, nitrogen takes up 78%, oxygen had 21%, while the remaining gases take the remaining 1%.

A solvent is a substance or the component of a solution that has the capacity to dissolve other substances

In a mixture consisting of 2 or more substances, the substance with the highest volume usually acts as the solvent.

In this case, nitrogen holds the highest volume of all the gases in the graph. Thus, it can be considered as the solvent while the remaining gases are the solutes.

B, D in the diagram represents the transition from liquid to gas. A phase diagram is a sort of figure that is used in physical chemistry.

A phase diagram is a sort of figure that is used in physical the field of chemistry engineering, mineralogy, as well as materials science to demonstrate the conditions (pressure, temperatures, volume, etc.) that exist when thermodynamically different phases (such solid, liquid, or gaseous states) arise and coexist at equilibrium.

Lines of equilibrium, also known as phase boundaries, or circumstances under which different phases may exist at equilibrium, are typical elements of a phase diagram. Phase changes take place along equilibration lines. Despite their frequent occurrence, metastable phases are not equilibrium phases, hence they are not depicted on phase diagrams. B, D  in the diagram represents the transition from liquid to gas.

Therefore, B, D in the diagram represents the transition from liquid to gas.

Answer:

The rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes.

Explanation:

Rock cycle(Attachment-1)

The rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.

The rock cycle is defined as the process through which the three main rock types i.e. igneous, metamorphic and sedimentary rock transfer from one type to another type.

The plate tectonics is defined as a theory that earth's outer shell is divided into large slabs of solid rocks known as "plates" that glide over earth mantle, the rocky inner layer above earth's core.

Thus, the rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.

Answer:

Explanation:

The concept Arrhenius equation is used here to determine the temperature dependence of the rate of a reaction. An increase in temperature increases the rate of a reaction. The correct option is B.

The rate of a chemical reaction is affected by the factors like temperature and activation energy. The influence of these factors on the rate of the reaction is explained by the Arrhenius equation.

The equation is given as:

[tex]k = A. e^{-} ^{E_{a} } /RT[/tex]

k - Rate constant

A - Frequency factor

Eₐ - Activation energy

R - Gas constant

T - Temperature

Since 'Temperature' appears in the denominator of the negative power of the exponential factor of the equation, it is evident that an increase in temperature increases the value of rate constant and thereby increases the rate of the reaction.

Thus the correct option is B.

Answer:

Congestive heart failure

Explanation:

Congestive heart failure happens when your heart gets too weak to pump blood from the lungs out to the body. Pressure builds up in the heart which puts pressure on the blood vessels of the lungs. This will lead to leakage of the vessels and the fluids build up in the air sacs of the lungs. This condition is called pulmonary edema.

Pulmonary edema occurs when fluid builds up in the lungs making it hard to breathe. It may start out as running out of breath easily but if left untreated (both conditions) symptoms get worse over time.

After the 4s sublevel is filled with two electrons, ten electrons fill the 3d sublevel, which is slightly higher in energy than the 4s sublevel. After the 3d sublevel is filled, the remaining three electrons will be in orbitals in the 4p sublevel. Thus, the electron configuration for arsenic is [Ar] 4s(2 squared) 3d(10 squared) 4p(3 squared).
