Answer 1: The correct answer is b. convergent continental-continental boundary.

A convergent continental-continental boundary refers to a convergent plate boundary where two continental plates meet or come together. When this happens, a forceful collision occurs, and structures like mountains start to form. The Himalaya mountain range is formed as a result of the convergence of the Indian and Eurasian continental plates.

Answer 2: The correct answer is d. convergent oceanic-oceanic boundary.

Volcanic island arcs refers to a curved line of volcanoes formed from the subduction (sinking) of one oceanic plate below another plate. Examples of volcanic island arcs include Japanese Islands and Alaskan Islands.

Answer 3: The correct answer is b.convergent oceanic-continental boundary.

A continental volcanic arc is an arc-shaped chain of volcanoes that form from the subduction of an oceanic plate under a continental plate.

Explanation:

The genotype of 50% of offspring will be Gg, 25% will be gg, and 25% will be GG. Hence, it is true.

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype. In other words, it is the genetic makeup of an organism. Phenotypes are determined by genotypes.

There are three different genotype types: homozygous dominant (PP), homozygous recessive (PP), and heterozygous (Pp). Examples of genotypes are hair color, skin color, height, hair texture, and blood group.

When two parents who are both Gg (Bb) for a gene are crossed, then the genotype of their offspring will be GG, gg, Gg. Hence, it is true.

Answer:

interior plains

Explanation:

edge 2021

Answer:

Around.

Explanation:

A chemical formula helps scientists to show or illustrate the type and number of atoms present in a particular molecule or compound by using numerical subscript, ions and atomic symbol of a chemical element.

This ultimately implies that, a chemical formula is used to describe or denote the exact amount of atoms that make up a molecule or compound.

The type of bond which is formed when the atoms of a chemical element are sharing electrons is known as covalent bond. Thus, when two (2) atoms of a chemical element comes close together, the nucleus of one of the atom attracts the other atom's electrons.

However, before bonding takes place, the atom's electrons spend most of their time around the nuclei of each atom.

Answer:

It forms from two hydrogen atoms, each with one electron in a 1s orbital. Both hydrogen atoms share the two electrons in the covalent bond, and each acquires a helium-like electron configuration.

Answer:

Q = 214.005 J

Explanation:

Given that,

Mass, m = 2.5 g

The hydrogen gas is heated from 17.0°C to 23.0°C.

The specific heat capacity of hydrogen is 14.267 J/g C.

We need to find how much energy is absorbed.

The formula for the energy absorbed is given by :

[tex]Q=mc\Delta T\\\\Q=2.5\times 14.267 \times (23-17)\\\\Q=214.005\ J[/tex]

So, the required energy is 214.005 J.

Moles-n₂

Solution

Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles  

The ratio of gas volume will be equal to the ratio of gas moles

[tex]\tt \dfrac{V_1}{V_2}=\dfrac{n_1}{n_2}[/tex]

Input the values :

n₂ = (V₂ x n₁)/V₁

n₂ = (28.4 x 1.4)/22.4

Weight of Chloroform : = 2.862 kg

Given

Density 1.483 g/ml

Volume = 1.93 L

Required

Weight of Chloroform

Solution

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]

ρ = density  

m = mass  

v = volume  

Convert density to kg/L :

=1.483g/ml = 1.483 kg/L

So the weight(mass) :

= ρ x V

= 1.483 kg/L x 1.93 L

= 2.862 kg

Given :

Number of molecules of hydrogen peroxide, N = 4.5 × 10²².

To Find :

The mass of given molecules of hydrogen peroxide.

Solution :

We know, 1 mole of every compound contains Nₐ = 6.022 × 10²³ molecules.

So, number of moles of hydrogen peroxide is :

[tex]n = \dfrac{N}{N_a}\\\\n = \dfrac{4.5\times 10^{22}}{6.022\times 10^{23}}\\\\n = 0.0747 \ moles[/tex]

Now, mass of hydrogen peroxide is given as :

m = n × M.M

m = 0.0747 × 34 grams

m = 2.54 grams

Hence, this is the required solution.

Answer:

Na (sodium)

Explanation:

An atom, which is the smallest indivisible particle of an element, contains three sub-atomic particles namely: proton, electron, and neutron. An atom is said to be neutrally charged if it contains a charge 0.

In a neutral atom, the number of electrons and the number of protons in an element are equal. These numbers are called the ATOMIC NUMBER. That is, in a neutral atom;

proton no. = electron no. = Atomic no.

Hence, in this case where Silicon atom has an electron number of 14. If three of this electrons are removed, there will be 11 electrons left, hence, this atom becomes SODIUM element, which has 11 electrons in its atom, with chemical symbol Na.

The final temperature : 317 °C

Given

V₁=2.5 L

V₂ = 5 L

T₁ = 22 + 273 = 295 K

Required

The temperature, T₂

Solution

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

Input the value :

T₂ = (T₁ x V₂) : V₁

T₂ = (295 x 5) : 2.5

T₂ = 590 K = 317 °C

Answer: ADF

Explanation: On my moms it’s right

The statements describe how heat flows in foil are heat flows in all directions, Heat flows from the cooler atoms to the warmer atoms, Heat flows from the warmer atoms to the cooler atoms. Therefore, option A, D and E are correct.

Heat is the result of the movement of kinetic energy within a material or an item, or from an energy source to a material or an object. Radiation, conduction, and convection are the three mechanisms through which such energy can be transferred.

Due to its extraordinary thinness and shine, aluminum foil has special characteristics. It bounces heat waves back outward rather than effectively absorbing or conducting heat. This explains why aluminum foil cools almost instantly after being removed from the oven, even after it has been there for some time.

The majority of the radiation released by a heated object is reflected onto the object when it is wrapped in reflective aluminum foil.

Thus, option A, D and E are correct.

The number of atoms : 33

Given

The chemical formula: 3Mg(OH₄)₂

Required

The number of atoms

Solution

The chemical formula of a compound shows the mole ratio and the number of each of its constituent components (number of atoms)

Usually, the ratio of the elements in a compound is indicated by their subscript number after the monoatomic or polyatomic in the compound

While the coefficient in front of the compound indicates the number of molecules

In the chemical formula 3Mg (OH₄) ₂, there are 3 molecules of Mg (OH₄) ₂, so the number of atoms of the elements:

Mg = 3

O = 3 x 2 = 6

H = 3 x 4 x 2 = 24

Total atoms = 3 + 6 + 24 = 33
