What is evidence of the dynamo theory?

1 answer:

3 0

Dynamo theory makes certain predictions. One is that a dynamo-induced magnetic field can exist only where a molten core exists within a fast-spinning planet. Small celestial bodies, such as Mars and the asteroids, long ago lost their heat, which shuts down the necessary convection near their cores. Venus is large enough to have retained its heat, but it spins very slowly, reducing the motion of its core and weakening the field. Mercury, which is too small to retain its primordial heat, does have a magnetic field as a result of its extreme inclination, which is allowed for in dynamo theory.

When comparing the two elements K and Ge , the more metallic element is__________ based on periodic trends alone.

Inessa [10]

Answer:

Option D and Option B

When comparing the two elements K and Ge , the more metallic element is_____K_____ based on periodic trends alone.

When comparing the two elements Sb and Pb , the more metallic element is_____Pb______ based on periodic

Explanation:

The metallic characteristic increases when we move down a column in a periodic table or when we move left in the row.

Potassium and Germanium are located on the same row, but germanium lies on the right side of potassium. Thus, potassium (K) is more metallic than Germanium (Ge)

While Lead (Pb) lies to left of Sb in the adjacent column and is also lies below Sb. Hence Pb is more metallic than Sb

How many grams of silver chromate, Ag2CrO4, are produced from 57.7

Anastasy [175]

48.3 g AgNO3 / 169.9 g/mol = 0.284 moles AgNO3
0.284 mol AgNO3 X (1 mol Ag2CrO4/2 mol AgNO3) = 0.142 mol Ag2CrO4
0.142 mol Ag2CrO4 X 331.7 g/mol = 47.1 g Ag2CrO4
