High temperature causes a faster reaction
Answer:
Initial Velocity is when movement begins. When a body is at rest, the initial velocity is at 0 m/s.
Explanation:
Initial Velocity is the velocity at time interval t = 0
Answer:
Compounds that have the same molecular formula but different chemical structures are called isomers.
Answer:
144 g of phosphorus contain 4.65 moles.
Explanation:
Given data:
Mass of phosphorus (P) = 144 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of phosphorus is 31 g/mol
Now we will put the values in formula.
Number of moles = 144 g/ 31 g/mol
Number of moles = 4.65 mol
Thus, 144 g of phosphorus contain 4.65 moles.
