The moles which were measured out is calculated using the following formula
moles = mass/molar mass
molar mass of CuBr2.4H20 = 63.5 Cu + ( 2 x79.9) br + ( 18 x4_) h20 = 295.3 g/mol
moles is therefore= 5.2 g/ 295.3 g/mol= 0.0176 moles
Answer:
Generally, interactions with air, water and living organisms cause the weathering of rocks. Although there are two major types of weathering processes, physical weathering and chemical weathering cannot be separated, and they often work together at different rates to break large rocks into smaller pieces over time.

Answer:
The density is 
Explanation:
From the question we are told that
the lattice constant is 
The density of Copper (
) is mathematically represented as
Where Z is the number of units in a unit cell and for BCC crystals Z =2
M is the molar mass of copper which same for Copper with a value of
is the Avogadro's constant with a value of 
Substituting values
Answer:
$474.30
Explanation:
23.25 × 102 = 2371.5 (total amount of money produced from pallets)
2371.5/5 = 474.3 (payout per worker)
Answer:
D
Explanation:
What an interesting amusing question.
The formula for KE = 1/2 m v^2.
v implies that there is motion.
The answer you are looking for is the body of water that has 0 for v.
A cloud moves, so it is not the answer.
A hailstone moves until it hits the ground. I'm assuming it's either on it's way down or it is caught in some sort of updraft in a cumulonimbus cloud. So it has motion.
Same comment for a raindrop. It has a v until it hits the ground so I'm assuming it is not the answer.
I've never seen a puddle of water move. It can only evaporate. So of all your choices, this one (D) is likely the right answer.
