An antenna
Explanation:
Radio waves are received by antennas
I think the correct answer from the choices listed above is the first option. Compared to compounds that possess only dipole-dipole intermolecular forces, compounds that possess hydrogen bonding generally have <span>higher melting points. This is because hydrogen bonding is a stronger force than dipole-dipole.</span>
Answer:
Molar mass = 27 g/mol
Explanation:
Given data;
Number of moles of Al = 0.2 mol
Mass of Al = 5.4 g
Molar mass of Al = ?
Solution:
Formula:
Number of moles = mass/molar mass
By putting values,
0.2 mol = 5.4 g/ molar mass
Molar mass = 5.4 g/ 0.2 mol
Molar mass = 27 g/mol
Answer:
She needs to know the Mass and acceleration
