Answer:

A simple test for the prescence of hydrogen gas is to light a splint and put it in the smoke present. If it makes a squeaky pop sound, then hydrogen gas is present. The hydrogen gas produced is combustible, and will therefore burn when it reacts with oxygen gas

SUPPLEMENTARY QUESTION
sergiy2304 [10]

Answer:

850 Calories.

Explanation:

The following data were obtained from the question:

Mass (M) = 50 g

Initial temperature (T1) = 20 °C

Final temperature (T2) = 37 °C

Specific heat capacity (C) of water = 1 cal/g°C

Heat absorbed (Q) =..?

Next, we shall determine the change in temperature of water.

This can be obtained as follow:

Initial temperature (T1) = 20 °C

Final temperature (T2) = 37 °C

Change in temperature (ΔT) =..?

Change in temperature (ΔT) = T2 – T1

Change in temperature (ΔT) = 37 – 20

Change in temperature (ΔT) = 17 °C

Finally, we shall determine the heat absorbed. This can be obtained as follow:

Mass (M) = 50 g

Specific heat capacity (C) of water = 1 cal/g°C.

Change in temperature (ΔT) = 17 °C

Heat absorbed (Q) =..?

Q = MCΔT

Q = 50 x 1 x 17

Q = 850 Calories

Therefore, the heat absorbed is 850 Calories.

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.
