HURRY WILL GIVE BRAINLIETS How are proteins and nucleic acids related? They both provide energy. They both carry genetic information. The structure of proteins is determined by nucleic acids. The subunits of nucleic acids are also the subunits of proteins.

Answer: if pressure rises in closed vessel and temperature is low enough,

Gas may condense to liquid state

Typically, this happens when we raise the pressure at room temperature, but there are other situations that aren't covered, including lowering the temperature at room pressure.

Temperature is defined as a measurement of an object or substance's warmth or coldness in relation to a standard value.  As opposed to extensive characteristics, like mass or volume, temperature is referred to as an intense property—one that is independent of the quantity of matter being considered—along with pressure, density, and other comparable properties.

If the temperature is low enough and pressure rises in a closed vessel, A gas can turn into a liquid form.

Thus, typically, this happens when we raise the pressure at room temperature, but there are other situations that aren't covered, including lowering the temperature at room pressure.

Answer:

Aluminum sulfate with barium nitrate to produce burin and aluminum nitrate

Aluminium hydroxide and barium nitrate are produced as a result of the chemical reaction between barium and aluminium nitrate. The reaction's balanced equation is as follows: [tex]2 Al + 3 Ba (NO_3)_3 \rightarrow 3 Ba(NO_3)_2 + 2 Al(OH)_3[/tex]

Chemical reactions are essential natural processes that take place and are in charge of the innumerable alterations and transformations we experience every day. They include the forming and breaking of chemical bonds between atoms, which causes the atoms to be rearranged to produce new compounds with various properties. The concepts of mass and energy conservation control chemical processes. The idea of balanced chemical equations came about because the total number of atoms of each element involved in a reaction stays constant both before and after the reaction. Aluminium hydroxide and barium nitrate are produced as a result of the chemical reaction between barium and aluminium nitrate. The reaction's balanced equation is as follows: [tex]2 Al + 3 Ba (NO_3)_3 \rightarrow 3 Ba(NO_3)_2 + 2 Al(OH)_3[/tex]

Answer:

electromagnetic waves

Explanation:

The waves that do not need a medium to travel through are known as electromagnetic waves.

These waves do not need any medium for their propagation or traveling. The waves have different wavelength and energy factors depending upon their rate of propagation. EMR waves travel from the sun to the earth in space.

Examples of electromagnetic waves are Xrays, gamma rays, radio waves, and more.

Answer:

The pH of a 0.10 Maqueous Ba(OH)2 solution at 25°C is 13.30

Explanation:

The balanced equation is Ba(OH)2(s)→Ba2++2OH−

This indicates that the concentration is 0.2 M

We will find H+ ion concentration

As we know that

[H+][OH−]=1.0×10−14M

Given -  

[OH−]=2.0×10−1M

Putting value of [OH-] in above equation we get -  

[H+]=5.0×10−14M

pH=−log10[H+]

pH=−log10[5.0×10−14] = 13.30.

Qué es Crecimiento poblacional:

El crecimiento poblacional se refiere al incremento del número de habitantes en un espacio y tiempo determinado, el cual se puede medir a través de una fórmula aritmética. También se puede emplear como sinónimo el término crecimiento demográfico.

Cuando se hace mención al crecimiento poblacional se puede hacer referencia a cualquier especie animal, sin embargo, se suele usar para referirse a los seres humanos, en especial cuando se realizan investigaciones acerca del crecimiento de la población.

Los datos que se obtienen de estos análisis son de gran importancia, tanto para los gobiernos de un país como, para las diferentes organizaciones internacionales.

Cabe resaltar que durante el siglo XX la población de seres humanos ha crecido y sigue creciendo en gran porcentaje, lo que ha generado preocupación, en especial por sus consecuencias sobre el uso y cuidado de los recursos naturales, entre otros.

Las zonas urbanas son las que presentan mayor crecimiento demográfico, así como, los países en vías de desarrollo. Por el contrario, el crecimiento poblacional es menor en los países desarrollados.

Por ejemplo, el crecimiento poblacional en México ha ido en aumento a lo largo de su historia, es el país con más habitantes hispanohablantes en América Latina. México tiene una población aproximada a 130 millones de habitantes, y se estima que seguirá creciendo gracias a diversos factores gracias a su continuo desarrollo político, económico y social.

Photosynthesis

Explanation:

Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen. The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower formation, and fruit development.

Explanation:

Freezing water can break rock without any change in the minerals that form the rock (physical weathering). This usually produces small particles and sand. Water with dissolved gases and other chemicals causes the minerals in rocks to be changed, leading to the deterioration of the rock (chemical weathering).

Explanation:

Rubidium was discovered by the German chemists Robert Bunsen and Gustav Kirchhoff in 1861 while analyzing samples of the mineral lepidolite with a device called a spectroscope. The sample produced a set of deep red spectral lines they had never seen before. Bunsen was eventually able to isolate samples of rubidium metal. Today, most rubidium is obtained as a byproduct of refining lithium.

Answer:

1. B = 1.13M

2. A. 8.46%

3. D = 0.0199

Explanation:

1. Molarity of a a solution = number of moles of solute/ volume of solution in L

Number of moles of solute = mass of solute/molar mass of solute

Molar mass of NaC₂H₃O₂ = 82 g/mol, mass of NaC₂H₃O₂ = 245 g

Number of moles of NaC₂H₃O₂ = 245 g / 82 g/mol = 2.988 moles

Molarity of solution = 2.988 mols/ 2.65 L = 1.13 M

2. Percentage by mass of a substance = mass of substance /mass of solution × 100%

Mass of 2.65 L of water = density × volume

Density of water = 1 Kg/L = 1000 g/L; volume of waterb= 2.65 L

Mass of water = 1000 g/L × 2.65 L = 2650 g

Mass of solution = mass of water + mass of solute = 245 + 2650 =2895 g

Percentage by mass of NaC₂H₃O₂ = 245/2895 × 100% = 8.46%

3. Mole fraction of NaC₂H₃O₂ = moles of NaC₂H₃O₂/moles of solution

Moles of water = mass /molar mass

Mass of water = 2650 g; molar mass of water = 18 g/mol

Moles of water = 2650 g / 18 g/mol = 147.222 moles

Moles of solution = moles of solute + moles of water = 147.222 + 2.988 = 150.21

Moles of NaC₂H₃O₂ =2.988 moles

Moles fraction of NaC₂H₃O₂ =2.988/150.21 = 0.0199
