Total density of filled ball with hydrogen gas: ![\frac{0.12g+0.050344g}{0.560L} = 0.3041g/L](https://tex.z-dn.net/?f=%5Cfrac%7B0.12g%2B0.050344g%7D%7B0.560L%7D%20%3D%200.3041g%2FL)
The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d). The ball filled with hydrogen will float in the air because total density of filled ball is lessor than the density of an air.
Density of hydrogen gas = ![d_2 = 0.0899g/L](https://tex.z-dn.net/?f=d_2%20%3D%200.0899g%2FL)

Alkenes on reaction with meta-chloroperoxybenzoic acid (MCPBA ) produces epoxides. When styrene is reacted with mCPBA it gives 2-phenyloxirane as shown below,
Answer: a communicable disease
Explanation: key word was transmitted and it was transmitted from a INFECTED living thing and then transmitted to another living thing
Answer:
Explanation:
For work to be done, force must be applied to move an object in the direction of the applied force.
Work is the product of force and distance. Workdone describes a change of energy between places.
If we apply force to a body without moving it through a distance, no work is done.
Work is only done when force is applied to move or displace a body.
If we only apply force and no movement occurs, no work is done..
The unit of force is Joules.
Event 1 is an example of a chemical reaction.
<u>Explanation:</u>
Whenever if two solutions are mixed, then if there is any color change, or evolution of any vapors, bubbles or gas formation or if there is any formation of a color or white precipitate confirms that the occurrence of a chemical reaction.
If nothing happens said above then it is said that there is no chemical reaction occurs.
Here in the event 1 a clear liquid in one beaker poured into clear liquid in beaker 2 then there is a formation of orange liquid, which means there is a formation of a new colored liquid confirms that the chemical reaction occurred.
