How many molecules are in 4.5 moles of CO2?

Chemistry
1 answer:
serg [7]3 years ago
5 0

Answer:

2.71 × 10^24 molecules

Explanation:

We are given;

Moles of CO₂ as 4.5 moles

We are required to determine the number of molecules

From the Avogadro's constant;

1 mole of a molecular compound contains 6.022 × 10^23 molecules

Therefore;

Molecules of CO₂ = Moles of CO₂ × Avogadro's constant

That is;  

               = 4.5 moles × 6.022 × 10^23 molecules/mole

               = 2.71 × 10^24 molecules

Hence, 4.5 moles of CO₂ contains 2.71 × 10^24 molecules

The inhibition caused by the final end product of a reaction is called
Troyanec [42]

Answer:

Non competitive inhibition

Explanation:

Hello,

During enzymatic catalysis, the active sites could be occupied by the very same products' molecules turning out into an inhibition (the reaction starts to slow down since to active places are available for the reagents to react). Nonetheless this inhibition is not competitive as long as the product does not react due to the active sites it is occupying.

Best regards.

How do scientists classify intrusive igneous features? according to shape, texture, and their distance from the nearest volcanic
Nataliya [291]

according to shape, size, and their relationship to surrounding layers of rock

Explanation:

Scientists classify intrusive features according to their shape, size and relationship to surrounding layers of rocks.

Intrusive igneous features are the sills, di/kes, batholith, laccoiith, lopolith e.t.c

  • When magma cools and solidifies within the earth crust, they form intrusive igneous rocks.
  • Intrusive igneous rocks differs from one another in their shape, size and relationship to surrounding rocks.
  • For example, batholith is a large intrusive body that extends for several kilometers in the earth surface.
  • Sills and di/kes are smaller bodies. Sills forms parallel to orientation of rocks in an area. Di/kes are known to cut across the orientation.
