Which type of landforms forms at the plate boundary as a result of this stress<br>​
stealth61 [152]

Answer:

Landform: MID-OCEAN RIDGE Plate Boundary: DIVERGENT Type of Plates: 2 Oceanic Plates (OP) pull apart How is it formed? Two oceanic plates (OP) move away from each other, allowing magma to rise up from inside the Earth. The magma reaches the bottom of the ocean, turns in to lava and cools (forming new rock)

What volume will 0.405 g of krypton gas occupy at STP?
Rufina [12.5K]

Answer:

The answer to your question is V = 0.108 L or 108 ml

Explanation:

Data

Volume = ?

mass = 0.405 g

Temperature = 273°K

Pressure = 1 atm

Process

1.- Convert mass of Kr to moles

                  83.8 g of Kr -------------------- 1 mol

                     0.405 g     -------------------  x

                     x = (0.405 x 1) / 83.8

                     x = 0.0048 moles

2.- Use the Ideal gas law to solve this problem

                   PV = nRT

- Solve for V

                      V = nRT / P

- Substitution

                      V = (0.0048)(0.082)(273) / 1

- Simplification

                       V = 0.108 / 1

- Result

                       V = 0.108 L

Water can resist a greater external force than ethanol can . Which statement best describes the difference
ANTONII [103]
<span>Water can resist a greater external force than ethanol due to its greater surface tension.

Reason:
             
Surface Tension in liquids is caused by the cohesive forces among the molecules of liquids at the surface. Means the liquids molecules at the surface have a net attractive interactions with molecules beneath them and cause them to contract causing tension.
              Now comparing water and ethanol, water has stronger intermolecular interactions than ethanol because water has two Hydrogen bongd donors (i.e. Hydrogens directly attached to oxygen atom) while ethanol has only one Hydrogen Bond Donors. This strong intermolecular interactions in water makes greater surface tension.</span>
