In 1735 Carlous Linneaus a Botanist said that there needs to be a way to classify organisms and living things. He decided that he'll sort organisms into seven major taxa, or groupings. He called the highest taxa kingdom and the lowest taxa species. This is known as the first idea in the process of Linnaean Taxonomy.

Then in 1990 Carl Wossen a microbiologist and biophysicist added to this idea saying that he Linnaean taxonomy works well, but it could be better. Thta there could be a better way into classifying and grouping kingdoms. He then created 3 domains: Bacteria, Archaea, and Eukarya, aka, regular bacteria, extreme bacteria, and everything else.

This furthermore is the method we use in classifying living things.

The answer is: B, Domain.

HELPPP!! Which describes one feature of the image formed by a convex mirror?

notka56 [123]

Answer:

The correct answer is - right-side up.

Explanation:

A diverging mirror is a curved mirror that can be bulge outside towards the source of light called a convex mirror or inward away from the source of light called a concave mirror.

A convex mirror is a mirror that forms an image bigger and but right side up or exact as the object direction also called a virtual image. It appears to be bigger than the real object and not upside down as concave mirrors.

If you have 16 g of manganese (II) nitrate tetrahydrate, how much water is required to prepare 0.16 M solution from this amount

nirvana33 [79]

<u>Answer:</u> The volume of water required is 398 mL

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Mass of solute (manganese (II) nitrate tetrahydrate) = 16 g

Molar mass of manganese (II) nitrate tetrahydrate = 251 g/mol

Molarity of solution = 0.16 M

Putting values in above equation, we get:

$0.16M=\frac{16g\times 1000}{251g/mol\times \text{Volume of solution}}\\\\\text{Volume of solution}=398mL$

Hence, the volume of water required is 398 mL

Hydrocarbons are separated from each other by a process called cracking distillation.

Nataliya [291]

True, cracking distillation is one process used to break hydrocarbons into smaller and more useful parts. This is achieved by using high temperatures and pressures with a catalyst. The most common catalyst used are the zeolites.

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) -

Plantae

protists

Animalia

Fungi

Table B: Enthalpy of Formation of Reactants and Products

Inessa [10]

The calculated enthalpy values are as follows:

Total enthalpy of reactants = -103.85 KJ/mol
Total enthalpy of products = -2057.68 KJ/mol
Enthalpy of reaction = -1953.83 kJ/mol

<h3>What is the enthalpy of the reaction?</h3>

The enthalpy of the reaction is determined as follows:

Enthalpy of reaction = Total enthalpy of products -Total enthalpy of reactants

Total enthalpy of reactants = (ΔHf of Reactant 1 x Coefficient) + (ΔHf of Reactant 2 x Coefficient)
Total enthalpy of products= (ΔHf of Product 1 x Coefficient) + (ΔHf of Product 2 x Coefficient)

Equation of reaction equation: C₃H₈ (g) + 5 O(g) → 4 H₂O(g) + 3CO₂(g)

Total enthalpy of reactants = (-103.85 * 1) + (0 * 5)

Total enthalpy of reactants = -103.85 + 0

Total enthalpy of reactants = -103.85 KJ/mol

Total enthalpy of products = (-393.51 * 4) +(-241.82 * 3)

Total enthalpy of products = (-1574.04) + (-483.64)

Total enthalpy of products = -2057.68 KJ/mol

Enthalpy of reaction = -2057.68 KJ/mol -(-103.85 KJ/mol)

Enthalpy of reaction = -1953.83 kJ/mol

In conclusion, the enthalpy of the reaction is determined from the difference between the total enthalpy of products and reactants.
