<span>The only effect that it has is when the magma is cooling (so if it's on the surface, it's now lava), any magnetic elements will align their dipoles with the north and south poles of the magnetic field.
Hope this helps!</span>
Answer:
2.3 x 10-23 g.
Explanation:
The mass of a single atom is the mass number, 14, is the mass in grams of one mole of carbon.
One mole of Nitrogen atom is 6.022 x 1023 atoms (Avogadro's number). This can then used to convert a nitogen atom to grams by the ratio:
mass of 1 atom / 1 atom = mass of a mole of atoms / 6.022 x 10^23 atoms.
mass of 1 atom = mass of a mole of atoms / 6.022 x 1023
mass of 1 N atom = 14 / 6.022 x 10^23 N atoms
mass of 1 N atom = 2.325 x 10^-23 g
The mass of a single Nitrogen atom is 2.325 x 10-23 g.
Answer:
nuclear energy
Explanation:
this holds the nucleus together
Answer: -
- 0.348°C is the melting point of a solution in which 2.5 grams of sodium chloride is added to 230 mL of water
Explanation: -
Mass of NaCl = 2.5 g
Molar mass of NaCl = 23 x 1 + 35.5 x 1 = 58.5 g / mol
Number of moles of NaCl = Mass of NaCl / Molar mass of NaCl
= 2.5 /58.5
= 0.043 mol
230mL of water has 0.043 mol.
1000mL of water has (0.043 mol x 1000 mL ) / 230mL
= 0.187 mol
Thus molality of NaCl =0.187 m
The molal freezing point depression constant of water = 1.86 °C/m
Depression in freezing point = 1.86 °C/m x 0.187 m
= 0.348°C
Melting point = 0 - 0.348°C
= - 0.348°C
Answer:
D) Water is less dense as a liquid than as a solid because of changes in bond structure.
