Which energy transformation occurs in an endothermic reaction

Chemistry
1 answer:
anygoal [31]2 years ago
8 0

Answer:

heat energy

Explanation:

Chemical reactions often involve changes in energy due to the breaking and formation of bonds. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic.

galben [10]

Answer:

0.21\ \text{kg/s}

Explanation:

P = Pressure = 0.48\ \text{atm}=0.48\times 101325\ \text{Pa}

V = Volume = 450\ \text{L/s}=450\times 10^{-3}\ \text{m}^3/\text{s}

R = Gas constant = 8.314\ \text{J/mol K}

T = Temperature = (264+273.15)\ \text{K}

The reaction is

2H_2S+3O_2\rightarrow 2SO_2+2H_2O

From ideal gas equation we have

PV=nRT\\\Rightarrow n=\dfrac{PV}{RT}\\\Rightarrow n=\dfrac{0.48\times101325\times 450\times 10^{-3}}{8.314\times (264+273.15)}\\\Rightarrow n=4.9\ \text{mol}

Moles of SO_2 produced is

\dfrac{2}{3}\times 4.9=3.267\ \text{moles}

Molar mass of SO_2 = 64.066 g/mol

Production rate is

3.267\times 64.066=209.3\ \text{g/s}=0.21\ \text{kg/s}

The rate at which sulfur dioxide is being produced 0.21\ \text{kg/s}.

a covalent bond involves: a. transferring of b. sharing protons c. transferring protons d. sharing electrons
Bas_tet [7]

A covalent bond involves: <u>d. sharing electrons</u>

The atoms of a molecule are held together by electrical forces that hold the atoms together, this is due to the electrical attraction between the electrons of the atom of one element and the nucleus of the other atom, this force of attraction is called covalent bond.

A covalent bond involves the sharing of electrons that are in the last energy layer of the atoms because they are the most likely or willing to be shared.

An example of a covalent bond is the bond between a hydrogen atom and a carbon atom in methane.

<h3>What is an atom?</h3>

The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.

decide how to supersets these substances? If if is not possible, please write "cannot be separated" on the space provided​
abruzzese [7]

Answer: (although the question does not sate whether if you separate them physically or through energy. so i did both)

1. can be separated (When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen)

2. can be separated, but through electrolysis, fiscally moving a crane to generate electricity to separate the molecules

3. Most solid particles, composed of diamagnetic or weak paramagnetic materials, cannot be extracted by a conventional magnetic separator. physically cannot be separated. but through heat yes

4. but there is a catch: doing so requires energy. ... If energy from coal were applied to drive the decomposition reaction, more CO2 would be released than consumed, because no process is perfectly efficient. so it cant be separated physically

5. it can be separated but it needs energy physically cannot be separated.

Which of the following best represents potential energy being converted to kinetic energy? (2 points) The chemical energy in a b
Ilia_Sergeevich [38]

Answer: A woman kicks a soccer ball and scores a goal.

Explanation:

Potential energy: it is the energy possessed by the body due to its position.

Kinetic energy: it is the energy possessed by the the body  due to its motion.

When a woman kick's a soccer ball she transferred her potential energy to soccer ball.Due to this action soccer ball comes into motion which means potential energy imparted to the ball starts getting converted into kinetic energy.
