When you mix sodium, which is a soft silvery metal, with chlorine, which is a yellowish gas, a solid white crystal called sodium chloride is formed. Which are the reactants?
A.) sodium and sodium chloride
B.) sodium chloride and chlorine
C.) sodium and chlorine
Answers
The correct choice is
C.) sodium and chlorine
In a reaction, reactants are the compound or elements which gets combined or reacts to give another compound known as product. Here sodium is getting combined with chlorine gas to give the product as sodium chloride. hence Sodium and chlorine can be termed as reactants and sodium chloride can be termed as product.

Answers
Answer:
A balloon is floating up into the air at 1 m/s.
Explanation:
Velocity is the displacement divided by the time;
Velocity =
It is a vector quantity that has magnitude and direction.
The choice that shows a change in direction is a correct specification of velocity.
A balloon floating up into the air at 1m/s shows no directional change.

What is an eclipse?
When a planetary body passes in front of another planetary body and is visible from a third planetary body, an eclipse is created. Based on the relative positions of the sun, moon, and earth at the time of the eclipse, there are various types of eclipses in our solar system. For instance, a lunar eclipse occurs when the earth passes between the moon and the sun. The moon is pulled into the earth's shadow during a lunar eclipse, obstructing the sun's rays from reaching the moon. The sun, earth, and moon are also very tightly aligned during this time. Only with a full moon can there be a lunar eclipse.
For the solar eclipse to happen the light from the sun is obstructed by the moon observing from the earth.
Hence, Jake's experiment has a flaw stand facing the light bulb is the best statement that describes a method to correct the flaw in Jake's experiment. therefore the correct option is A.

Conservation of mechanical energy
The principle of conservation of energy states that sum of potential energy and kinetic energy is constant.
M.A = P.E + K.E
where;
- P.E is the potential energy
- K.E is the kinetic energy
The mechanical energy is always conserved, although it may be converted from one form to another.
The rolling ball follows the law of conservation of energy, the lost energy may be transformed to thermal energy.
