Answer:

Nepal aims to achieve universal access to clean, reliable and affordable renewable energy solutions by 2030. It is expected to reduce dependence on traditional and imported energy by increasing access to renewable energy. The use of solar energy is more reliable than traditional electricity in Nepal.

According to law of conservation of energy,solar energy is a renewable source of energy as it's heat can be converted to other forms of energy  and can be conserved and is being looked as an alternative in Nepal.

According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.

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.

Answer:1 answer number 1

Explanation:

Answer: There is 0.8 liters (L) of water required to be added to prepare 4800mL of 0.5M NaCl from a 3M NaCl stock solution.

Explanation:

Given: [tex]M_{1}[/tex] = 0.5 M        

[tex]V_{1}[/tex] = 4800 mL

Convert mL into L as follows.

[tex]1 mL = 0.001 L\\4800 mL = 4800 mL \times \frac{0.001 L}{1 mL}\\= 4.8 L[/tex]

[tex]M_{2}[/tex] = 3 M

Formula used to calculate the volume of water required as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula.

[tex]M_{1}V_{1} = M_{2}V_{2}\\0.5 M \times 4.8 L = 3 M \times V_{2}\\V_{2} = \frac{0.5 M \times 4.8 L}{3 M}\\= 0.8 L[/tex]

Thus, we can conclude that 0.8 liters (L) of water need to be added to prepare 4800mL of 0.5M NaCl from a 3M NaCl stock solution.

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:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we're finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

We have

[tex]P_2 = \frac{6.4 \times 0.87}{20.5} = \frac{5.568}{20.5} \\ = 0.2716.... \\ \\ = 0.27 \: \: \: atm[/tex]

But

1 atm = 14.7 psi

Then 0.27 atm =

Answer:

gO₂ = 32.32 g

Explanation:

In this case, let's write the general equation:

2H₂ + O₂ -------> 2H₂O

In this case, we can use the 1° law, which is mass conservation. If the product has 36.36 g of water, then in the reactants we should have the same 36.36 g.

According to this, we already have 4.04 of hydrogen, then the remaining to reach the 36.36 g would be:

gO₂ = 36.36 - 4.04

Answer:

Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A pH of 7 is neutral

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.
