Answer:

2.57 g of H₂

Solution:

The Balance Chemical Equation is as follow,

N₂ + 3 H₂ → 2 NH₃

According to Balance equation,

34.06 g (2 moles) NH₃ is produced by = 6.04 g (3 moles) of H₂

So,

14.51 g of NH₃ will be produced by = X g of H₂

Solving for X,

X = (14.51 g × 6.04 g) ÷ 34.06 g

X = 2.57 g of H₂

Define and describe each of the following forms of energy and then classify each as either: potential energy, kinetic energy, or

TiliK225 [7]

Potential energy: It is an energy stored in an object due to its position.

Chemical energy: It is an energy stored in a bonds of a chemical compound and this energy is released during the reaction in the form of heat.

Elastic energy: It is a stored potential energy in an elastic object when subjected to any deformation or change in shape.

Gravitational energy : It is an energy possessed by an object due its position in a gravitational field.

Electric energy: Energy due to flow of charged particles. It is a type of a stored potential energy due to relative position of charged particle .

Nuclear energy : it is an energy stored in a nucleus of an atom. This energy kept the particles present inside the nucleus binded together.

Static electricity: It is an electricity which arises due to presence of imbalance in charge within or on the surface of the material.

Transfer of some quantity of energy:

Heat energy: Transfer or flow of energy from one object to another in form of heat. This transfer is due to difference in temperature of two objects.

Electromagnetic energy: It is an form of energy emitted by the magnetic field and electric field vibrating perpendicular to each other while propagation of the electromagnetic wave. Energy transfer takes place in from of electromagnetic wave.

Sound energy ; it is the energy produced by the vibration of sound waves. the energy transferred from one substance to another in form of sound wave.

Kinetic energy: Its an energy possessed by an object due its motion.

Movement of mass : It is an energy which leads to movement of the mass of an object.

Thermal work : It is an energy posses by the body due to movement of the particles.

enyata [817]

Answer:

Which of the following substances are ionic?

Check all that apply.

AlCl3

MgI2

C2H5OH

NH3

Explanation:

An ionic substance is formed between a positively charged cation and a negatively charged anion.

Ionic substances are generally formed from metal and nonmetal atoms with the metal atoms forming the cations and the nonmetal atoms forming the anions.

Among the given substances,

MgI2 is an ionic substance.

Since Mg is the metal atom. It forms a cation.

I is a nonmetal atom. It forms anion.

Hence,

MgI2 is an ionic substance.

Though AlCl3 looks like an ionic substance it is a covalent compound.

This is due to the high polarizability of $Al^3+$ ion.

The remaining two compounds do not contain any metal atoms.

So, ethanol and NH3 are not ionic compounds.

Answer:

MgI2

What volume (in mL) will a sample of F2 gas occupy in a syringe at 5.5 atm, if the F2 has a volume of 25.0 mL at 1.2 atm?

Paha777 [63]

Answer:

5.45mL

Explanation:

Using Boyle's law equation:

P1V1 = P2V2

Where; P1 = initial pressure

P2 = final pressure

V1 = initial volume

V2 = final volume

According to this question, P1 = 1.2atm, V1 = 25mL, P2 = 5.5atm, V2 = ?

1.2 × 25 = 5.5 × V2

30 = 5.5V2

V2 = 30/5.5

V2 = 5.45mL

Therefore, 5.45 mL sample of F2 gas will occupy a syringe at 5.5atm.
