The resulting carbonic acid decomposes into carbon dioxide and water molecules.

<h3 /><h3>How does carbonic acid decompose?</h3>

Carbonic acid goes by the chemical formula H2CO3.

When heated, carbonic acid decomposes to give two products which are:

  • A gaseous compound in the form of carbon dioxide
  • A neutral compound in the form of water molecules

The overall equation of the reaction is as follows:

   H₂CO₃ ⇌ H₂O + CO₂

If a 185-lb patient is prescribed 145mg. What dosage is the patient receiving in mg/kg of his body weight?
Anestetic [448]

Answer:

1.728 mg/kg

Explanation:

First have to convert the patient's weight to kg

1 lb = 0.454 kg

185 lb in kg = 83.9 kg

Then we have to divide the dose per the weight of the patient

145 mg for 83.9 kg =  145/83.9

= 1.728 mg/kg

Answer:

The correct answer is -

Prokaryotic unicellular -

Eubacteria - is the domain of unicellular organisms that has a prokaryotic cell

Archaebacteria - is one of the two domains of the prokaryotic organisms that are unicellular.

Eukaryotic multicellular (autotroph) -

Plantae - is the multicellular kingdom of the eukaryotic cells and as they produce their own food by photosynthesis called autotrophs.

protists - the autotrophic protists that are multicellular comes under algae, especially red algae.

Eukaryotic multicellular (heterotroph) -

Animalia - The Animalia kingdom is the kingdom of the heterotrophic eukaryotic organism that mostly has multicellular bodies. They depend on plants or other animals for their food.

Fungi - are mostly heterotrophic eukaryotic as they get their nutrient from other organisms are mostly multicellular.

Protist - some protists are heterotrophic as well.

Eukaryotic multicellular/unicellular (heterotroph/autotroph) -

How many atoms are in one molecule of Iron II sulfate
dezoksy [38]
Answer:
             The number of atoms contained by one molecule of Iron (II) Sulfate are 6.

Explanation:
                   Iron (II) Sulfate is mage up of two parts. One is the Positive part which constitutes of Fe⁺² and a negative part which constitutes of a polyatomic anion i.e. SO₄²⁻. As there are four Oxygen and one sulfur atom in sulfate Ion so sulfate ion contains 5 atoms in total. Therefore, five atoms from sulfate iona dn one atom of Iron ion makes a total of 6 atoms in one molecule of Iron (II) Sulfate.

Consider the reaction: 2N2O(g) ⇌ O2(g) + 2N2(g). Which of the following will cause a shift in the equilibrium to the right? 1. A
Illusion [34]

Answer:

1. Add N2O and

3. Remove N2

Explanation:

In equilibrium, there is a balance between the concentrations of the reactants and products. If more reactants are added, the equilibrium will shift to the right, favoring the forward reaction. This cause an increase in the concentration of the product and the equilibrium constant is unchanged.

Products can also be removed in order to increase the amount of products formed, forward reaction. This shifts the equilibrium to the right.

In the reaction 2N2O <-----> O2 + 2N2, adding N2O to the mixture favors the forward reaction and more products are formed, equilibrium shifts to the right.

Also, removing the product formed favors the forward reaction as more products will be formed in order to achieve equilibrium. The equilibrium therefore shifts to the right.
