Which formula represents a hydrate compound?​

Answer:

The answer to your question is A.

D. Protective coloration.  Protective coloration, also known as "crypsis," is a defense mechanism used by animals to avoid detection by predators or prey.

An illustration of protective coloration, which is a sort of camouflage, is how white arctic hares blend in with the white snow around them. Animals use protective coloration, commonly referred to as "crypsis," as a defensive strategy to evade being seen by predators or prey.

In this instance, the white arctic hares' fur is the same shade as that of their snowy environment. Their chances of survival are increased by this merging, which enables them to remain unnoticed and effectively hidden from predators like polar foxes or birds of prey. They have a better chance of escaping or avoiding detection when they are well-camouflaged, making it difficult for predators to see them against the white background.

1. Insulin

2. Keratin

Explanation:

Proteins are one of the four biological molecules found in living systems. They are polymeric molecules made up of monomeric units called AMINO ACIDS. Proteins perform a wide variety of functions in the body ranging from enzymatic functions to structural roles.

Two examples of proteins found in the body are keratin, insulin. Keratin is a structural protein located in the skin, hair and nails while insulin is an enzymatic protein that aids in digestion.

Answer: The volume of the gas is 0.84 Liters

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1530 mm Hg = 2.01 atm     (760mmHg=1atm)

V = Volume of gas = ?

n = number of moles = 0.275

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]75K[/tex]

[tex]V=\frac{nRT}{P}[/tex]

[tex]V=\frac{0.275atm\times 0.0820 Latm/K mol\times 75K}{2.01atm}=0.84L[/tex]

Thus the volume of the gas is 0.84 Liters

Answer:

[tex]\boxed {\boxed {\sf A. \ SiCl_4}}[/tex]

Explanation:

We are given the compound name: silicon tetrachloride.

Silicon is a metalloid and chlorine is a nonmetal, therefore we must use the rules of molecular compounds. Molecular compounds use prefixes to name the compounds. Break up the compound into 2 parts.

1. Silicon

The first element: silicon, has no prefix. Therefore, a prefix of mono (1) is implied.

2. Tetrachloride

The -ide suffix is added to the second element, so this is really chlorine. The prefix of tetra means 4.

So there is 1 silicon (Si) atom and 4 chlorine (Cl) atoms. The formula must be SiCl₄

Answer:

Draw circles to represent the electron shell of each atom overlapping the circles where the atoms are bonded. Add dots to represent the outer electrons of one type of atom (H). Add crosses to represent the outer electrons of the other type of atom (Cl). Make sure the electrons are always in pairs.

Explanation:

Using the concept of Avogadro's number, the number of atoms present is 4.4 * 10^24 atoms.

Professor Avogadro provided a nice way of calculating the number of atoms in a molecules by the use of the Avogardro's number. Now we know that 1 mole of a substance contains about 6.02 * 10^23 atoms, molecules ions etc.

Hence;

1 mole of sulfur dioxide contains 6.02 * 10^23 atoms

7.32 moles of sulfur dioxide contains 7.32 moles  * 6.02 * 10^23 atoms/1 mole

= 4.4 * 10^24 atoms.

Explanation:

The equation of the reaction is given as;

6CO2 + 6H2O → C6H12O6 + 6O2

How many molecules of CO2 are present?

6 moles

How many atoms of oxygen are present in the reactants?

(6 * 2) + (6 * 1 ) = 12 + 6 = 18

How many atoms of carbon are present in the products?

(6 * 1 ) = 6

How many total atoms are present in C6H12O6?

6 + 12 + 6 = 24 atoms

Is the equation above balanced or unbalanced?

This is a balanced equation since the number of atoms of the elements is the same in the reactant and products.
