Answer:
East
Explanation:
Given Newton's third law of motion; "Action and reaction are equal and opposite", when a student jumps off a sled toward the west after it stops at the bottom of an icy hill, the sled will move in the East direction.
This is because, the force exerted on the sled is a reaction force and is opposite in direction to the force that thrusts the boy westward though equal in magnitude with the former.
i think it’s D , not sure though
But nitrogen is inert at room temperature whereas chlorine is highly reactive, the reason is: Nitrogen exists as N triple bond N at room temperature while chlorine exists as Cl single bond Cl at room temperature. Since the bond dissociation energy of triple bond is larger than that of single bond.
Answer:
Mass = 824.57 g
Explanation:
Given data:
Mass of bromine = ?
Number of moles of bromine = 5.16 mol
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of bromine = 159.8 g/mol
by putting values,
Mass = 5.16 mol × 159.8 g/mol
Mass = 824.57 g
