How many molecules are in 1.75 moles of Caco3?
saw5 [17]

Answer:

1.054 x 10²⁴ molecules

Explanation:

In order to convert moles <em>of any given substance</em> into a number of molecules, we need to use <em>Avogadro's number</em>, which states the number of molecules -or atoms, in the case of elements- present in one mol:

  • In one mol there are 6.023x10²³ molecules.

We now <u>convert 1.75 moles into molecules</u>:

  • 1.75 mol * 6.023x10²³ molecules/mol = 1.05x10²⁴ molecules

Which statement correctly describes the transfer of energy in the food chain in the land​
Aleks [24]

Answer:

The question lacks options, the options are:

A) Energy is transferred to consumers, which convert it to nitrogen and use it to make amino acid

B) Energy from producers is converted into oxygen and transformed to consumers.

C) Energy from the sun is stored by green plants and transferred to consumers.

D) Energy is transferred to consumers, which use it to produce food.

The answer is C

Explanation:

Organisms obtain energy in an ecosystem by feeding on one another in a chain called FOOD CHAIN. Energy is transferred when one organism feeds on another. A food chain always begins with a PRODUCER, which is an autotrophic organism capable of producing its own food via light energy from the sun.

In a terrestrial ecosystem, the energy a plant captures via Its Chlorophyll is used to produce food during photosynthesis. This energy is stored in the plants and transferred when a set of organisms called PRIMARY CONSUMER feeds on the plant. The transfer continues in that order till decomposers.

put 8 in front of the oxygen in the reactants side to make it 16 molecules then put a 5 in front of the co2 in the product side to balance the carbon atoms then put a 6 in front of the H20 on the product side this balances both the hydrogen and oxygen atoms here is a representation

C5H12(g)+8O2(g)=5CO2(g)+6H20
