Identify the type of energy involved in each step:

Chemistry
2 answers:
horrorfan [7]3 years ago

Answer: 1) Electric energy

2) Heat energy

3) Thermal energy

Explanation:

1) You flip on the switch on a lamp - <u>Electric energy</u>.

Because, when we flip on the switch, the chemical energy of lamp is converted into electric energy as the electrons moves with the help of circuit.

2) The light bulb lights up -  <u>Heat energy</u>

when a light bulb lights up after there is flip on the switch on a lamp, then electric energy is converted into heat energy as the electrons passes through the resistor which makes bulb lights up.

3) The light bulb causes the lamp shade to melt - <u>Thermal energy</u>

Thermal energy is occurred due to change in temperature  i.e heat energy, in which objects start moving within the object.

When the bulb lights up, its temperature get increased makes the lamp shade to melt, so the heat energy is converted into thermal energy.

Answer:

a. Electric Energy

b. Light Energy

c. Thermal Energy

Explanation:

a. When a lamp is turned on by means of a switch, electric energy is usually used, since that is the form of energy that is generated when there is a potential difference between two points, which allows to establish an electric current, that electric current travels through the wires up to the bulb of the lamp

b. In this case a case of light energy is presented since that is the energy transported by the light and that is manifested on the matter in different ways, one of them is to remove the electrons from the metals. This is what usually happens in some types of light bulbs, that when the displacement of the electrons is promoted, a beam of light is generated.

c. The last case is a case of thermal energy, since this energy is that expressed as the total kinetic energy resulting from the random movements of atoms and molecules. This was what could happen in case b, when the beam of light was generated. This energy is released in the form of heat, and may present high temperatures.

Differentiate between short period and long period in modern periodic table​
AfilCa [17]
The difference between short period and long period is based upon the number of elements in each period. Shortest period is the first period which contains elements, while the longest period is the 6th period which contains 32 elements.

For the reaction 2A(g) â B(g), the equilibrium constant is Kp = 0.76. A reaction mixture initially contains 4.0 atm of gas (PA =
timofeeve [1]

Answer: (a) The reaction mixture will proceed toward products.

Explanation:

Equilibrium constant is defined as the ratio of pressure of products to the pressure of reactants each raised to the power their stoichiometric ratios. It is expressed as K_p

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

2A(g)\rightleftharpoons B(g)

The expression for Q_p is written as:

Q_p=\frac{p_B}{(p_A)^2}

Q_p=\frac{(2.0)}{(2.0)^2}

Q_p=0.5

K_p=0.76

Thus as K_p>Q_p , the reaction will shift towards the right i.e. towards the product side.
