Answer:

The two most basic types of bonds are characterized as either ionic or covalent. In ionic bonding, atoms transfer electrons to each other. ... In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.

Explanation:

Answer:

C. 12.8 liters.

Explanation:

The Standard Temperature and Pressure (STP) of a gas are 273.15 K and 100 kilopascals. From Avogadro's Law, a mole of carbon dioxide contains [tex]6.022 \times 10^{23}[/tex] molecules. If we suppose that carbon dioxide behaves ideally, then the equation of state for ideal gas is:

[tex]P\cdot V = n\cdot R_{u}\cdot T[/tex] (1)

[tex]P\cdot V = \frac{r\cdot R_{u}\cdot T}{N_{A}}[/tex] (1b)

Where:

[tex]P[/tex] - Pressure, measured in pascals.

[tex]V[/tex] - Volume, measured in liters.

[tex]r[/tex] - Amount of molecules, no unit.

[tex]N_{A}[/tex] - Avogadro's number, no unit.

[tex]R_{u}[/tex] - Ideal gas constant, measured in pascal-liters per mole-Kelvin.

[tex]T[/tex] - Temperature, measured in Kelvin.

If we know that [tex]P = 100000\,Pa[/tex], [tex]r = 3.44\times 10^{23}[/tex], [tex]N_{A} = 6.022\times 10^{23}[/tex], [tex]T = 273.15\,K[/tex] and [tex]R_{u} = 8.314\times 10^{3}\,\frac{L\cdot Pa}{mol\cdot K}[/tex], then the volume of carbon dioxide at STP is:

[tex]V = \frac{r\cdot R_{u}\cdot T}{N_{A}\cdot P}[/tex]

[tex]V = \frac{(3.44\times 10^{23})\cdot \left(8.314\times 10^{3}\,\frac{L\cdot Pa}{mol\cdot K} \right)\cdot (273.15\,K)}{(6.022\times 10^{23})\cdot (100000\,Pa)}[/tex]

[tex]V = 12.972\,L[/tex]

Therefore, the correct answer is C.

Answer:

I think option B , bcz it is continuous process

The continuous, interconnected processes that move water through Earth's spheres best describe the water cycle. Therefore, option B is correct.

The water cycle can be demonstrated as the continuous movement of water from the Earth's surface to clouds and from clouds to the back surface. The sun, air, and other factors are included in the physical process of the water cycle, water goes through each of the states of matter such as solid, liquid, as well as gas.

The water cycle is a combination of the physical processes where water evaporates from the earth's surface into the atmosphere, cools down, condenses produces rain in clouds, and again comes back to the surface of the earth with the precipitation process.

Water on the Earth's surface of the water after rain gets collected in the form of rivers, groundwater,  ponds, etc., and combines in oceans and gets evaporated.

The evaporation process includes the exchange of water from the surface in the form of water vapors to the atmosphere. The process of evaporation cools the temperature of the atmosphere as the sunlight on the surface of the earth makes the warm.

Answer:

Uniformitarianism is the idea that the natural processes operating today are the same as the natural processes that operated in the past

Answer:

[tex]\boxed {\boxed {\sf 4.20 *10^{24} \ atoms \ Al }}[/tex]

Explanation:

To convert from moles to atoms, we must us Avogadro's number: 6.022*10²³. This tells us the number of particles (atoms, molecules, etc.) in 1 mole of a substance. In this case, it is atoms of aluminum.

We can use the number as a fraction.

[tex]\frac{6.022*10^{23} atoms \ Al}{1 \ mol \ Al}[/tex]

Multiply by the given number of moles: 6.98

[tex]6.98 \ mol \ Al *\frac{6.022*10^{23} atoms \ Al}{1 \ mol \ Al}[/tex]

The moles of aluminum will cancel.

[tex]6.98 *\frac{6.022*10^{23} atoms \ Al}{1 }[/tex]

The denominator of 1 can be ignored.

[tex]6.98 * {6.022*10^{23} atoms \ Al}[/tex]

Multiply.

[tex]4.203356*10^{24} \ atoms \ Al[/tex]

The original measurement of moles has 3 significant figures, so our answer must have the same.

For the number we calculated, that is the hundredth place. The 3 in the thousandth place tells us to leave the 0.

[tex]4.20 *10^{24} \ atoms \ Al[/tex]

There are about 4.20*10²⁴ atoms of aluminum in 6.98 moles.

Answer:

the deep ocean

Explanation:

goog   le

The layer which is closest to the surface is least dense.

The ocean can be divided into three main layers:

The surface layer (also known as the epipelagic zone), which extends from the surface to about 200 meters deep and is the warmest and lightest layer.

The mesopelagic zone (or twilight zone), which extends from 200 to 1000 meters deep and is characterized by limited light and declining temperatures.

The bathypelagic zone (or midnight zone), which extends from 1000 to 4000 meters deep and is the coldest, darkest, and most pressure-filled layer.

Below the bathypelagic zone lies the abyssopelagic zone, which extends from 4000 to the ocean floor and is characterized by near-constant darkness and extremely cold temperatures.

Answer: it’s only c

Explanation:

The correct statement regarding groups on the periodic table is statement C which is elements in a group have similar properties.

A. Elements in a group may have different numbers of protons, as the group represents elements with similar valence electron configurations, but the number of protons in the nucleus can vary.

B. Elements in a group do not have the same number of electron shells. Elements within the same group have similar outer electron configurations, which determine their chemical properties. The number of electron shells increases as you go down the group.

C. Elements in a group have similar properties. Elements within the same group share similar chemical behavior due to their similar outer electron configurations. This similarity leads to recurring patterns in their physical and chemical properties.

D. Elements in a group may have different numbers of neutrons. The number of neutrons can vary within a group as different isotopes of an element can exist, which have the same number of protons but different numbers of neutrons.

Therefore, the correct option is option c

alligators protect their offspring by digging a hole where they bury their eggs and stay all the meanwhile on top of the hole protecting their offspring. baby alligators can be eaten by birds and snakes. they for short periods of time take a break to hunt for food. when their hatchling hatch they keep them in their mouth until they're in the water. alligators are good protecting their offspring.

seahorses make the males take care of their baby's till they are born and male seahorses join together in groups to help protect eachother. once the babies are born male seahorses are still together helping raise their pups

Alligators bury their eggs in a hole that they have dug, and they then spend the entire time on top of the hole guarding their young. Therefore, by below given ways animals take care of their offspring.

Offspring refers to the new organism that an organism creates via the act of reproduction. Both birds and snakes can consume young alligators. They stop for brief periods of time to go food hunting. They hold their hatchlings in their mouths until they are in the water after they hatch. Alligators do a superb job of safeguarding their young.

Male seahorses form groups to assist defend one another, and they are required to care for their young until they are born. Male seahorses continue to work together to nurture their young after the babies are born.

Answer:

[tex]10^{-7} m[/tex]

Explanation: just took the test; picture below:)

A solution is defined as a homogeneous mixture made up of two or more non-reacting substances. The [H⁺] for a neutral solution is 10⁻⁷ M . The correct option is A.

A solution which is neither acidic nor basic and contains equal amount of hydrogen ion and hydroxide ion concentration. The distilled water is an best example of a neutral solution. It always has a pH 7.

The pH of a solution is defined as the negative logarithm of hydronium ion concentration in moles per litre. It can be given as:

pH = - log [H₃O⁺]

For pure water or neutral solution at 298 K

[H₃O⁺] = [OH⁻] = 1 × 10⁻⁷ mol L⁻¹

The pH of acidic solution is more than 7 and for basic solution the pH will be greater than 7.

Answer:

Explanation:

A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in solution—so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.
