Which indicator would tell scientists the most about future climate change

Answer:

691.7 mmHg is the resulting pressure

Explanation:

Tha Gay-Lussac's law states that the pressure of a gas is directly proportional to its absolute temperature under constant volume. The equation is:

P1T2 = P2T1

Where P is pressure and T asbolute temperature of 1, initial state and 2, final state of the gas.

Computing the values of the problem:

T1 = 273 + 25 = 298K

P1 = 755.0mmHg

T2 = 273 + 0 = 273K

P2 = ?

755.0mmHg*273K = P2*298K

Explanation:

50 moles of ammonia gas are produced in the following reaction if 25 moles of nitrogen gas reacts with hydrogen. Therefore, the correct option is option C.

In the National System of Units, the mole represents the unit of substance amount. However many elementary units of a particular substance are present inside an object as well as sample is determined by the quantity of that material. There are precisely  6.022×10²³ elementary entities in a mole.

An elementary object may include an atom, any molecule, and ion, an ion pair, or perhaps a subatomic particle like an electron depending upon what the substance is. 

N[tex]_2[/tex](g) + 3H[tex]_2[/tex](g). → 2NH[tex]_3[/tex](g)

moles of nitrogen = 25 moles

the  mole ratio between nitrogen and ammonia is 1:2

moles of nitrogen = 25×2=50 moles

Therefore, the correct option is option C.

Explanation:

The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion whereby the scale of space itself changes. The universe does not expand "into" anything and does not require space to exist "outside" it.

Explanation:

What happen if your Adrenal Glands become overprotective of underproductive?

Answer: if your adrenals becomes overproductive it will lead to a health issue known as CUSHING'S SYNDROME while when they become underproductive it will lead to a health condition known as ADDISON'S DISEASE.

Explanation:

The adrenal glands are divided into two embryologically and functionally distinct parts: the adrenal cortex and adrenal medulla.

The adrenal cortex is part of the hypothalamic - pituitary - adrenal endocrine system. Morphologically, the adult adrenal cortex consists of three layers which include:

--> The outer thin layer: this is also called zona glomerulosa. It secrets only aldosterone.

--> The inner two layers: these comprises of the zona fasciculata and zona reticularis. They both form a functional unit and secrete most of the adrenocortical hormones.

The adrenal medulla is the inner part of the adrenal gland which secrets the adrenaline and noradrenaline hormones.thry take part in sympathetic nervous system.

When the adrenal glands become a OVERPRODUCTIVE, the adrenal cortex is highly affected. This may occur due to hyperstimulation of the adrenal gland by adrenocorticotrophic hormone,either from the pituitary gland or from an ectopic source or due to largely autonomous secretion by an adrenal tumor such as an adenoma or carcinoma. The increased endogenous cortisol production leads to a disorder known as CUSHING'S SYNDROME. The clinical and metabolic features include obesity, hyperglycaemia and hypertension.

Also when the adrenal glands become UNDERPRODUCTIVE, a health condition known as ADDISON'S DISEASE may occur. This is cause any the bilateral destruction of all zones of the adrenal cortex, usually as the result of an autoimmune process or mycotic infections. The resulting decrease in cortisol production may lead to clinical features such as hypotension, hypoglycemia, nausea and vomiting.

Answer:

0.629 gramos de PH3 es la máxima de cantidad que puede ser producida.

Explanation:

¡Hola!

En este caso, dado que tenemos la siguiente reacción química, la cual se puede balancear directamente:

[tex]Ca_3P_2+6H_2O\rightarrow 3Ca(OH)_2+2PH_3[/tex]

Podemos calcular la masa máxima de cualquier producto, digamos PH3, al comparar la masa de este, que 2 g the Ca3P2 y 1 g de H2O producen por separado y de acuerdo a la estequiometría:

[tex]2gCa_3P_2 *\frac{1molCa_3P_2 }{182.18gCa_3P_2 }*\frac{2molPH_3}{1molCa_3P_2 } *\frac{34gPH_3}{1molPH_3 } =0.747gPH_3\\\\1gH_2O *\frac{1molH_2O }{18.02gH_2O}*\frac{2molPH_3}{6molH_2O} *\frac{34gPH_3}{1molPH_3 } =0.629gPH_3[/tex]

De este modo, infermos que solamente 0.629 gramos the PH3 pueden ser obtenidos al ser el agua el reactivo límite.

Answer:

A motor (device that converts electrical energy into kinetic energy) runs by using the magnetic field formed by a flowing current formed into a loop.

Answer:

41.8 g of water.

Explanation:

To solve this, we introduce the concept of mol.

1 mol of anything contains 6.02×10²³ particles.

In this case, we talk about molecules of water.

Molecular weigh is 18 g/mol which indicates that 1 mol of water weighs 18 g.

So let's do the conversion

(18 g of water / 6.02×10²³ 1 mol of molecules) . 1.4×10²⁴ molecules = 41.8 g

Answer:

True; Water is stored in reservoirs.

Answer:

The pressure of the gas at 323 degrees Celsius is 2 atm.

Explanation:

Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

In short, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.

Gay-Lussac's law can be expressed mathematically as follows:

[tex]\frac{P}{T} =k[/tex]

Where P = pressure, T = temperature, K = Constant

Having two different states, an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{1 atm}{298 K} =\frac{P2}{596 K}[/tex]

Solving:

[tex]P2=\frac{1 atm}{298 K}*596 K[/tex]

P2= 2 atm

The pressure of the gas at 323 degrees Celsius is 2 atm.

The other relationship that will have a similar graph is volume versus temperature, because they are also directly proportional according to Charles's Law.

Charles's Law is a gas law that states that the volume of a fixed mass of gas at a constant pressure is directly proportional to its absolute temperature.

This means that as the temperature of a gas increases, the volume of the gas will also increase proportionally, and as the temperature of a gas decreases, the volume of the gas will decrease proportionally.

Therefore, if a graph of gas pressure versus the number of particles in a container is a straight line, a graph of volume versus temperature will have a similar shape and be directly proportional, because they are both affected by changes in temperature.

Answer:

Both the Earth and Venus show the appearance of igneous rocks due to the cooling of the magma.

Explanation:

As we know, ignea rock is the first step in the transformation of rocks. This rock is formed by the overflow of terrestrial magma which, upon cooling, turns into ignea rock, which will undergo metamorphism and transform into metamorphic rock, which will continue to undergo metamorphosis until it becomes the other rocks that complete the rock cycle. This is a terrestrial process that can be found on Venus, which also presents the cooling of magma in the formation of ignea rock, which will undergo metamorphism, transforming into other rocks, the way it occurs on Earth.

Explanation:

Answer: The pressure is 2.14 atm if the gas was heated to 373 K and the volume decreased to 1.90 L.

Explanation:

Given: [tex]V_{1} = 2.50 L[/tex],      [tex]P_{1} = 1.34 atm[/tex],       [tex]T_{1} = 308 K[/tex]

[tex]P_{2} = ?[/tex] ,            [tex]V_{2} = 1.90 L[/tex],          [tex]T_{1} = 373 K[/tex]

Formula used to calculate the final pressure is as follows.

[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]

Substitute the values into above formula as follows.

[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}\\\frac{1.34 atm \times 2.50 L}{308 K} = \frac{P_{2} \times 1.90 L}{373 K}\\P_{2} = \frac{1.34 atm \times 2.50 L \times 373}{308 K \times 1.90 L}\\= 2.14 atm[/tex]

Thus, we can conclude that the pressure is 2.14 atm if the gas was heated to 373 K and the volume decreased to 1.90 L.
