Answer by Mimiwhatsup: An amplitude is a node and an point along a standing wave where the wave has minimum amplitude.
Answer: proton number = 16
Electron number =16
Neutron number =16
Explanation: Mass number = 32
Atomic number = 16
atomic number = proton number = 16.
Since the atom is neutral, proton number is the same as electron number i.e Electron number = proton number =16
Mass number = proton + Neutron
32 = 16 + Neutron
Neutron = 32 — 16 = 16
Answer:
The cost is $0.063.
Explanation:
First, we need to express the volume of the hangar in liters. We know that 1 ft³ = 28.31 L, so using proportions:
The amount of vanillin required would be:
Finally, the price for such amount of vanillin is:
The mass of cobalt (III) needed is
m = 5.2 L (0.42 mol/L) ( 93 g/mol)
m = 97.65 g
The volume of nitric acid needed is
V = 5.2 L (0.42 mol/L) (3 mol / 1 mol) (1000 mL/1.6 mol)
V = 1968.75 mL
The moles of water produced is
n = 5.2 L (0.42 mol/L) (3 mol / 1 mol)
n = 3.15 moles
Answer:
dipole-dipole
Explanation:
Intermolecular forces exists between the molecules of a substance in a particular state of matter.
The type of intermolecular forces present in a substance is determined by the electronegativity difference between the atoms that compose the substance.
There is a non zero electronegativity difference between Br and F hence the molecule is polar and the intermolecular forces between the molecules of BrF are dipole-dipole forces.
