Answer:

[tex]\Rightarrow V_2 = 389mL[/tex]

Explanation:

To solve this question, we could use Charles' law since both the number of mole and pressure are constant

At STP pressure P = 760 tor and Temperature = 273K

V1 =425mL, T1 =298K and T2 =273K

and [tex]\frac{V_1}{T_1} =\frac{V_2}{T_2}[/tex]

[tex]\Rightarrow V_2 =T_2\times\frac{V_1}{T_1}[/tex]

[tex]\Rightarrow V_2 =273\times\frac{425}{298}[/tex]

Therefore, [tex]\Rightarrow V_2 = 389mL[/tex]

Explanation:

Answer:organelle 1

Explanation:

Organulo 1 is the organelle that  stores the information that determines an individual blood type. The correct option is option A.

A tiny cellular component known as an organelle serves a specialised purpose within a cell. The cytoplasm of prokaryotic and eukaryotic cells contains organelles. Organelles are frequently encased by a separate membrane in eukaryotic cells because they are more complicated.

Similar to the internal organs of the body, organelles are specialised and carry out important tasks required for proper cellular function. Organelles are responsible for a variety of tasks, such as powering a cell's energy needs and regulating its development and reproduction. Organulo 1 is the organelle that  stores the information that determines an individual blood type.

Therefore, Organulo 1 is the organelle that  stores the information that determines an individual blood type. The correct option is option A.

Answer:

Energy must be provided

Explanation:

Chemical bonds are initially stable, energy is required to break them apart.

Todo en un estado sólido de materia tiene una forma y una longitud distintas. El volumen de un objeto es la cantidad de espacio que ocupa. Un sólido es un bloque de madera que conserva su forma y volumen cuando se coloca sobre una mesa.

The rocks are classified as igneous, metamorphic, and sedimentary use the formation for classification purposes.

The outermost of them, called the crust, is composed of three types of rocks: magmatic, sedimentary and metamorphic. They are defined through the origin of several minerals and can be characterized with chemical composition, texture or shape, but the most used specification is based on composition.

The property does Valerie use for classification purposes is formation.

Answer:

2.3 grams per cubic cm

Explanation:

Density is equal to mass over volume, so

23/10=2.3

5.6 atm is  the partial pressure of the rest of the gases in the container other than the oxygen.

Each gas in a mixture adds to the overall pressure of a mixture. This portion represents the pressure. The pressure a gas would have if it were in its own volume and at its own temperature is known as the partial pressure. According to Dalton's law, the pressure distribution of an ideal gas mixture is equal to the combined partial pressures of the component gases.

The study of partial pressure is significant in the domains of physics, chemistry, and biology. The partial pressure of oxygen or carbon dioxide in the blood is used to calculate blood levels of each substance. The overall pressure in a container is equal to the sum of the partial pressures. The remaining gases must make up the remaining 5.6 atm if the oxygen partial pressure equals 4.2 atm and the sun reaches 9.8 atm in pressure.

Therefore, 5.6 atm is  the partial pressure of the rest of the gases in the container other than the oxygen.

Answer:

[tex]\lambda=6.56x10^{-7}m[/tex]

Explanation:

Hello there!

In this case, it possible to use the Rydberg equation in order to calculate the wavelength for this transition from n=3 to n=2 as shown below:

[tex]\frac{1}{\lambda} =R_H(\frac{1}{n_f^2}-\frac{1}{n_i^2} )[/tex]

Thus, we plug in the corresponding energy levels and the Rydberg constant to obtain:

[tex]\frac{1}{\lambda} =10973731.6m^{-1}(\frac{1}{2^2}-\frac{1}{3^2} )\\\\\frac{1}{\lambda} =1524129.4m^{-1}\\\\\lambda=\frac{1}{1524129.4m^{-1}} \\\\\lambda=6.56x10^{-7}m[/tex]

Explanation:

a) The word equation is;

silver chlorate + sodium phosphate ------> silver phosphate + sodium chlorate

b) The balanced reaction equation of the reaction is;

3AgClO3(aq) + Na3PO4(aq) ------->Ag3PO4(s) + 3NaClO3(aq)

c) amount of silver chlorate reacted = 287 g/191.319 g/mol = 1.5 moles

3 moles of silver chlorate yields 1 mole of silver phosphate

1.5 moles of silver chlorate yields 1.5 * 1/3 = 0.5 moles of silver phosphate

Amount of sodium phosphate reacted = 52.8 g/163.94 g/mol = 0.3 moles

1 mole of sodium phosphate yields 1 mole of silver phosphate

0.3 moles of sodium phosphate yields 0.3 moles of silver phosphate.

Hence the maximum number of grams mass of silver phosphate produced = 0.3 moles * 418.58 g/mol = 125.6 g

d) The excess reactant is silver chlorate while the limiting reactant is sodium phosphate

e) 3 moles of silver chlorate  reacts with 1 mole of sodium phosphate

  x moles of silver chlorate reacts with 0.3 moles of sodium phosphate

x = 3 * 0.3 = 0.9 moles of silver chlorate reacted

Mass of 0.9 moles of silver chlorate = 0.9 moles * 191.319 g/mol  = 172 g of silver chlorate

Hence mass of silver chlorate left over =  287 g - 172 g = 115 g

Answer:

If it's a buffer solution, the pH remains unchanged.

If it's a normal solution, and an acidic substance is added to it, the pH lowers.

If a basic substance is added to it, the pH increases.

When it could be closest to the Earth and farthest from it, the Moon passes the fastest as well as the slowest.

The only cosmic object known to contain life is Earth, which would be located third from the Sun. Although the Solar System contains enormous amounts of water, only Earth is home to liquid surface water. The oceans cover over 71% of Earth's crust, dwarfing its polar ice, lakes, including rivers.

The sole natural satellite of Earth would be the Moon. It makes up the Earth-Moon satellite system with Earth. Its diameter is equivalent to one-fourth of Earth. It should be the biggest satellite of a planet compared to the main, bigger than any existing dwarf planet, as well as the fifth biggest satellite in the Planetary System.

Answer:

Explanation:

A. It causes the genes of two different individuals to mix.

Answer:

No, although the bean crop can grow perfectly in full sun or a little shade in very warm places. It does not mean that they will adopt the growth patterns of the cactus, especially because this plant needs constant watering (in small quantities), very constant. Beans require good drainage for their growth.

Each vegetation have its own characteristics and the power of adaptation. A green bean cannot survive in a desert like a cactus in desert without water. It can only grow thick in soil with proper water content and nutrients.

Cactus is a type of plant grow in dry regions such as deserts. It can adapt in deserts without water for long time because, the plant have enough water storage in its stem.

Domestic vegetation such as bean, pea, nuts etc ill not grow in dry regions because they cannot adapt in deserts without water. The soil in deserts is dry and have no nutrients.

These conditions prevent the growth of vegetables in desert areas. Moreover, desert have summer season only. The extreme temperature over there will cause the normal plants to diminish.

Therefore, planting green bean in deserts will not make it grow thick like a cactus plant.
