DUE TONIGHT. LINKS DONT WORK SO PLS SHOW WORK. THANK YOU SO MUCH

Answers

Answer:

14°C

Explanation:

In order to use the ideal gas law, you need the number of moles of N2 present.

30.1 g x (mol / 28.02 g) = 1.07 mol N2

Use the ideal gas law: PV = nRT

Now isolate for T(temperature) and plug in your other values:

T = PV / nR

T = (25.2 atm)(1.00 L) / (1.07 mol)(0.08206)

T = 287 K

T(°C) = 287 K - 273 K = 14°C

Therefore, the temperature is 14°C

how does the water cycle sustains life
plz help! !!​

Answers

Water is constantly being cycled between the atmosphere, the ocean and the land. This cycling is a very important process that helps sustain life on Earth. When the sun heats water, the water evaporates or changes to water vapor. Water vapor rises and condenses or changes back into liquid water droplets.

A.65 Celsius

B. 68 Celsius

C. 70 Celsius

D. 72 Celsius

Answers

Answer:

Option B

Explanation:

We will check the solubility graph for potassium nitrate,  KNO 3. Based on the graph it can be said that the temperature of solution when 130 grams of KNO3 dissolves in 100 grams of water is near to 65 degree Celsius. Now if three grams of solute is increased then the temperature of the solution will increase by a degree or so and hence the most probable temperature would be 68 degree Celsius.

Hence, option B is correct

B. 68 Celsius

In phase 1, the substance is ice which is the solid phase.

In phase 2,it undergoes melting in a forward reaction.

In phase 3, the melting from phase 2 has now changed to water which is liquid phase.

In phase 4, the substance is undergoing a forward reaction known as evaporation.

In phase 5, the evaporation from stage 4 will turn the liquid into vapour known as the gas phase.

A) The substance is in the gas phase only in "region 5".

The heat of vaporization of a liquid is 84.0 J/g. How many joules of heat would it take to completely vaporize 172 g of this liquid at its boiling point?

Answers

Answer:

14,448 J of heat would it take to completely vaporize 172 g of this liquid at its boiling point.

Explanation:

The heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to Q = m*L, where L is called the latent heat of the substance and depends on the type of phase change.

During the evaporation process, a substance goes from a liquid to a gaseous state and needs to absorb a certain amount of heat from its immediate surroundings, which results in its cooling. The heat absorbed is called the heat of vaporization.

So, it is called "heat of vaporization", the energy required to change 1 gram of substance from a liquid state to a gaseous state at the boiling point.

In this case, being:

Q=?m= 172 gL= 84 [tex]\frac{J}{g}[/tex]

and replacing in the expression Q = m*L you get:

Q=172 g*84 [tex]\frac{J}{g}[/tex]

Q=14,448 J

14,448 J of heat would it take to completely vaporize 172 g of this liquid at its boiling point.

Answer:

1. 2Na + 2HCl = 2NaCl =H2

2. 2Mg + O2 = 2MgO

Explanation:

make sure that the number of atoms of each element is the same on each side of the equation  

1. 2Na + 2HCl = 2NaCl =H2

on LHS of equation,

Na = 2

H = 2

Cl =2

On RHS of equation,

Na=2

H= 2

Cl =2

2. 2Mg + O2 = 2MgO

on LHS of equation,

Mg = 2

O2 = 2

On RHS of equation,

Mg = 2

O2 = 2

A sample of gas occupies 806 ml at 26.0ºC and 998 mmHg. Find the volume of the gas at STP.

Answers

Answer:

966.4mL

Explanation:

Using the combined gas equation as follows:

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure

P2 = final pressure

V1 = initial volume

V2 = final volume

T1 = initial temperature (K)

T2 = final temperature (K)

According to this question, the following information were provided:

P1 = 998mmHg

P2 (STP) = 760mmHg

V1 = 806mL

V2 = ?

T1 = 26°C = 26 + 273 = 299K

T2 (STP) = 273K

P1V1/T1 = P2V2/T2

998 × 806/299 = 760 × V2/273

804388/299 = 760V2/273

2690.26 = 760V2/273

760V2 = 2690.26 × 273

760V2 = 734440.98

V2 = 734440.98 ÷ 760

V2 = 966.4mL

El acido nitrico se obtiene industrialmente por oxidacion de amoniaco (nh3), de acuerdo con la ecuacion: 4nh3 + 702 - h2o + hno2 + 2hno3 ¿ cuanto acido nitrico del 90% de pureza se podra obtener a partir de 1.36 kg de amoniaco?

Answers

Answer:

2800 g de ácido nítrico

Explanation:

La ecuación por la oxidación de amoniaco es:

4NH₃  +  7O₂  →  4H₂O  +  2HNO₂  +  2HNO₃

Si pensamos que el oxígeno es el reactivo limitante, trabajamos con el amoniaco. Convertimos su masa a moles:

1.36 kg = 1360 g

1360 g . 1mol  /17g = 80 moles

Si 4 moles de amoniaco pueden producir 2 moles de acido nítrico

80 moles producirán, (80 . 2)/4 = 40 moles.

Convertimos los moles a gramos:

40 mol . 63g /mol = 2520 g

Si le aplicamos la pureza

2520 g . 100/90 = 2800 g

It takes 2 g of chlorine to sanitize 1,000,000g of water. How much chlorine will it take to sanitize a 40,000-gallon pool? ( 1 gallon =3.7L; the density of water is 1.0g/ml ) Show your work

Answers

Answer:

0.1g (Gallon) of chlorine

Explanation:

Formula

1 gallon = 3.7L; the density of water is 1.0g/ml

Given

2g (gallon) of chlorine to sanitize = 1,000,000g (gallon) of water

Solve

If 2g (gallon) chlorine = 1,000,000g (gallon)

∴, ? chlorine = 40,000

The First step; set up an equation

1000000/2 = 40000/?

The Next step; divide 1 million to 2

1000000 ÷ 2 = 500000

Then, divide the result by 40000

40000 ÷ 500000 = 0.08

In the nearest unit that is 0.1

Therefore, it will take 0.1g (gallon) of chlorine to sanitize a 40,000-gallon pool.

Answer:

296

Explanation:

1 gallon = 3.7 L

40,000 gallon

= 40,000 × 3.7

= 148,000 L

1 g = 1 / 1000 L

1,000,000 g

= 1,000,000 / 1000

= 1,000 L

Let x be the amount of chlorine that will it take to sanitize a 40,000-gallon pool.

2 : 1,000 : : x : 148,000

2 / 1,000 = x / 148,000

x × 1,000 = 2 × 148,000

x = ( 2 × 148,000 ) / 1,000

= 2 × 148

x = 296 g

Therefore,

296 g of chlorine will it take to sanitize a 40,000-gallon pool.
