Ammonia is an important ingredient in many fertilizers. The main process by which ammonia is made is the Haber process. In this process, nitrogen gas and hydrogen gas are reacted to form ammonia at high temperatures. Which of the following most likely explains why this reaction is carried out at high temperature?Ammonia is unstable at room temperature. High temperatures increase the activation energy of the reaction. High temperatures make the gas molecules move more quickly. The reaction becomes exothermic at high temperatures.

B. Physical changes always involve the formation of a gas while chemical changes may not.
C. Physical changes can occur inside or outside the substance; chemical changes always occur outside.
D. Physical changes involve a change of state; chemical changes involve a change of shape.

Answers

Answer:

A is the answer.

Explanation:

Physical changes do not change the substance's composition but just the outside qualities. However, chemical changes change the composition of the substance and it's chemical properties.

In our solar system, Earth is located between which two planets?

Answers

The location of earth in the solar system is found between Venus and Mars.

What is a solar system?

A solar system is the gravitational bound system comprising the sun and the objects aligned in the orbit revolving around the sun. The foundation of the solar system is mediated billions of years ago with the huge interstellar cloud collapse.

The planets are present in the orbit bounded by the gravitational force of the sun and revolve around it. Earth is the planet that is said to have only one having the five elements that support life namely. fire, air, water, soil, and space.

The solar system is comprised of 9 planets with the nearest to the sun being mercury, and the farthest being Pluto. Earth is arranged as the third planet from the distance from the sun and is located between Venus and Mars.

A 22.5 g sample of a metal is heated to 65.00 °C and added to 25.00 g of water (c = 4.184 J/g °C) in a calorimeter. The water temperature rises from 25.55 °C to 35.25 °C. What is the specific heat capacity of the metal?

Answers

Answer:

The specific heat capacity of the metal is 1.143 J/g°C

Explanation:

A typical excersise of calorimetry:

Q = m . C . ΔT

ΔT = Final T° - Initial T°

m = mass

In this case, the heat released by the metal is gained by the water to rise its temperature.

Qmetal = Qwater

(We consider that metal was at the same T° of water)

22.5 g  . C . (65°C - 25.55°C) = 25 g .  4.184 J/g°C . (35.25°C - 25.55°C)

22.5 g  . C . 39.45°C = 25g . 4.184 J/g°C . 9.7°C

887.625 g.°C . C = 1014.62J

C = 1014.62J / 887.625 g.°C

C = 1.143 J/g°C

How many grams of kno3 pellets must be dissolved in water in order to prepare 100 ml of a 8 m kno3?

Answers

in 8M of KNO3, there are x moles of KNO3 divided by (100/1000)L of water (because molarity is concentration, given by no. of moles divided by total volume in liters).

by changing the subject of formula, x = 0.1L × 8M = 0.8mol

given the no. of mol of KNO3, mass of KNO3 is given by no. of mol multipled by the relative molecular mass of KNO3.

mass = 0.8mol × 101.10g/mol (or whatever your periodic table says) = 80.88g
