Hydrogen bonding

Explanation:

Hydrogen bonding between water molecules account for its high boiling point.

Intermolecular forces determines the bulk of the physical properties of matter.
Hydrogen bond is a special type of dipole dipole attraction
It forms when a hydrogen on one molecule attracts an electronegative atom on another usually Oxygen, fluorine and nitrogen.
These intermolecular forces are very strong and difficult to break.

If you have 10,000 grams of a substance that decays with a half-life of 14 days, then how much will you have after 56 days?

Crank

Answer: 625 grams

Explanation:

14 goes into 56, 4 times.

10,000÷2=5,000 - first half life

5,000÷2=2,500 - second half life

2,500÷2=1,250 - 3rd half life

1,250÷2= 625 - 4th half life

Note: don't type "grams" after 625, just type "625".

Determine the primary means of melting that would occur at divergent boundaries, convergent boundaries, and within a plate (intr

Schach [20]

By determining the primary means of melting that would occur at divergent boundaries and the appropriate labels to the respective Convergent plate boundary.

What is the Convergent plate boundary?

As the plate delves deeper into the convergent boundary, pressure and temperature rise along with it. When the pore water is released, this contributes to partial melting.

As a result, when the situation is at the melting curve, a rise in temperature will result in a large partial melt because of the presence of water. As seen in the wet peridotite melting curves in the aforementioned curves.

Only the peridotite's temperature changes during intraplate melting, not the pressure. Therefore, as the temperature rises, it will begin to melt.

Decompression causes melting at diverging boundaries. Temperature plays no part in this. As the plate delves deeper into the convergent boundary, pressure and temperature rise along with it.
