prisoha [69]

Answer:

The lipid bilayer made up of Palmitic acid will have a higher melting transition temperature

Explanation:

The one with a higher melting transition temperature is the lipid layer with a higher melting temperature

Melting temperature of palmitoleic acid = -0.5°C

Melting temperature of palmitic acid = 62.9°C

Hence the lipid bilayer made up of Palmitic acid will have a higher melting transition temperature

Which technology is NASA developing that will help astronauts reach Mars? Corona Freedom Orion Skylab
stiv31 [10]

Answer:

The answer is "Orion technology"

Explanation:

NASA tested that perhaps the abort system on the Biomechanical properties fires faster than that of the rocket, possibly costing colonists during launch or a crisis. It test is a significant step forward in Agency's plans again for the Artemis space mission, which will pave the way for human missions to The moon. NASA is building a humanoid spacecraft for long-range space missions for the first time in generations.  As just a result, they are beginning a new age of space travel. Orion would be used to transport the crew into space as a surveillance vehicle. Also, it helps astronauts to flights and ensures a safe return to orbit in the case of an emergency release.

What happens to sodium chloride when it dissolves in water
inn [45]

Image result for What happens to sodium chloride when it dissolves in water

Explanation: On addition to water the Na+ section of NaCl is attracted to the oxygen side of the water molecules, while the Cl- side is attracted to the hydrogens' side of the water molecule. This causes the sodium chloride to split in water, and the NaCl dissolves into separate Na+ and Cl- atoms

How many total atoms are in 0.170 g of p2o5?
Pachacha [2.7K]
7.20594 x 10^20

First you must determine how many moles of P3O5 you have. This is done by using the formula
Number of moles (n) = mass in grams of substance (m) /divided by/ Molar mass (M) [this is the sum of the atomic mass of all atoms in the compound]

n = 0.170 / P (31 x 2) + O (16 x 5)
n = 0.170 / 142
n = 0.001197 moles

Then you use avagadros number 6.02 x10^23 this is the number of atoms in one mole of any substance. Since you have 0.001197 moles you multiply the number of moles by avagadros number

0.001197 x (6.02 x 10^23)
= 7.20594 x 10^20 atoms
