Answer:
Molar mass of bromine is equal to 
Explanation:
The molar mass of HBr is equal to the sum of atomic weight of Bromine.
Atomic Weight of hydrogen is equal to 
Atomic Weight of Bromine is equal to 
Molar mass of Bromine
= Atomic Weight of hydrogen + Atomic Weight of Bromine
Molar mass of Bromine 
The Sun, like most other astronomical objects (planets, asteroids, galaxies, etc.), rotates on its axis. Unlike Earth and other solid objects, the entire Sun doesn't rotate at the same rate. ... The Sun's rotation rate decreases with increasing latitude, so that its rotation rate is slowest near its poles.
Answer:
Exothermic.
Explanation:
Exothermic is when he leaves the system. A way to remember is the "ex" which is a prefix/root/suffix or something that pretty much means leaving, I think. For example how it's in "Exodus" and "Exit", I think.
Endothermic is when it goes into the system. Similar to "ex" but with inside, I think. For example how it's in "Endoskeleton", I suppose.
Answer: Option (d) is the correct answer.
Explanation:
A tetarhedral geometry is the geometry which includes four atoms bonded to the central atom and it does not contain any lone pair of electron.
For example, 
has tetrahedral geometry.
Thus, we can conclude that a molecule which contains four bonded pairs of electrons and zero lone pairs. The name of the molecular geometry is tetrahedral.
Answer:
The sun's circumference is about 2,713,406 miles (4,366,813 km). It may be the biggest thing in this neighborhood, but the sun is just average compared to other stars. Betelgeuse, a red giant, is about 700 times bigger than the sun and about 14,000 times brighter.
