Answer:
The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume.

Answer:
The emission spectrum is formed when the electrons of a particular atom absorb energy and are excited (in this case by heating), reaching higher energy levels.
You can see it for example with an experiment where we light alcohol mixed with banana chips (it has potassium). The burning alcohol emits heat that makes potassium atoms excite and these in turn emit something red, orange light. If we add for example boric acid you see a green light.
Explanation:
Answer: The final concentration of a solution is 0.350 M
Explanation:
According to the dilution law,
where,
= concentration of concentrated acid solution = 12.0 M
= volume of concentrated acid solution = 35.0 ml
= concentration of diluted acid solution= ?
= volume of another acid solution= 1.20 L = 1200 ml
( 1L=1000ml)
Putting in the values:
The final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L is 0.350 M
Answer:
is is the process of combination of two or more small nuclei to form large nucleus having large amount of energy
Remember:
Density = mass/volume
Volume = mass/density
Volume = 193 g/ 19.3 g cm ^ -3
Volume = 10 cm^3
