NARA [144]3 years ago

Answer:

False

Explanation:

Diffusion uses the concentration gradient that has been set up, this is a naturally occurring phenomena, and using a diffusion gradient some small particles can cross over the cell membrane. Some bigger or polar molecules require facilitated diffusion to move these molecules across the membrane.

Facilitated diffusion still uses the gradient for passive transport. This means that ATP is not used to transport molecules.

The reason that glucose will not move into the cell via passive transport is because there is a higher concentration of glucose inside the cell, meaning it needs active transport to move glucose (against the concentration gradient) into the cell.

How many moles of N₂ are essential for generating 0.08 moles of Li₃N in the given reaction?
joja [24]
Each mole of N₂ generates 2 moles of Li₃N. Thus,
0.08 moles of Li₃N will require:
0.08 / 2
= 0.04 moles of N₂

The second option is correct.

The empirical formula for a compound is C2H4NO. If its molar mass is 232.2 g/mol, what is the molecular formula of the compound?
Irina18 [472]

Empirical formula mass

  • C2H4NO
  • 2(12)+4(1)+14+16
  • 30+24+4
  • 58g/mol

Molar mass=232.2g/mol

Find n

  • Molar mass/Empirical formula mass
  • 232.2/58
  • 4

Molecular formula

  • n×Empirical formula
  • 4(C2H4NO)
  • C8H16(NO)_4

Help? It would honestly mean a lot :(
melomori [17]

Answer:

1 1

5 2

6 1

8 3

10 3

6 3

9 3

13 3

Explanation:

First of you add the subscripts (the little numbers after the letters) and multiply the big numbers before the letters together to get the number of atoms

For Example:

O= 1 atom

Si{2}= 2 atoms

Mg{5}C{6}= 11 atoms

3Na{2}= 6 atoms

O(SiNa){2}= OSi{2}Na{2}= 5 atoms

Each Capital letter is a new Element

For Example:

O = 1 Element

NaSi = 2 Elements

Why are graphs used to understand an objects motion?
S_A_V [24]
Hello!

Graphs are used to understand an object's motion because they can show the exact location of the object at any given moment. 

This is done with the help of a reference system. The most common reference system is the Cartesian coordinate system, which describes the location of an object through a set of 2 or 3 coordinates (depending if the system is in 2D or 3D).

Studying graphs of movement, we can know if the movement is cyclical, or the direction of the movement, determine tendencies and overall getting an unambiguous and precise understanding of the motion.

Have a good day!
