Answer:
A boiling chip, boiling stone, porous bit or anti-bumping granule is a tiny, unevenly shaped piece of substance added to liquids to make them boil more calmly.
These help in making the liquid boil more easily
Answer:
Because the most common form of Nickel is Ni-58 while the most common form of Cobalt is Co-59, this means that Cobalt (which is number 27 on the periodic table) has 27 protons and 32 neutrons. Therefore 1 less proton but 2 more neutrons and hence has a greater mass than Nickel.
Explanation:
Molar mass Na = 23g/mol
46g = 456/2 = 2mol
1mol = 6.022*10^23 atoms
2mol = 2*6.022*10623
= 1.204*10^24 atoms
Answer:
True
Explanation:
Since the waves have low frequency that means the wavelength is going to be longer. Hope this helps
Answer:
New volume V2 = 120.4 ml
Explanation:
Given:
Pressure P1 = 1.12 atm
New pressure P2 = 1.12[1+0.25] = 1.4 atm
Old volume V1 = 150.5 ml
Find:
New volume V2
Computation:
P1V1 = P2V2
(1.12)(150.5) = (1.4)(V2)
V2 = 120.4 ml
New volume V2 = 120.4 ml
