Answer:

1. Golgi apparatus- 2. produces lysosomes

2. Lysosome- 3. digests foreign material

3. Smooth endoplasmic reticulum- 1. produces lipids and fats

4. nucleus- 4. command other organelles

1. Golgi apparatus- 2. produces lysosomes

The proteins are synthesized in a rough endoplasmic reticulum. These proteins are packed in a vesicle and send to the golgi apparatus. The proteins and others cellular components not required by the cell are packed by golgi apparatus in a vesicle or number of vesicles also consisting of digestive enzymes. These vesicles are called as lysosomes. 2. Lysosome- 3. digests foreign material

Lysosomes are the organelles found in animal cell, they contain digestive enzymes like acid hydrolases. The enzymes facilitates the digestion of organelles, foreign agents like viruses and bacteria, food particles and other cellular wastes.

3. Smooth endoplasmic reticulum- 1. produces lipids and fats

Smooth endoplasmic reticulum is a meshwork of tubes it is attached with the periphery of the cell. The main function of the endoplasmic reticulum is the synthesis and storage of lipids like phospholipids, cholesterol and fats.

4. nucleus- 4. command other organelles

The nucleus is the command center of the cell. It contains the hereditary information of the cell in the form of genetic material. The genetic material is the form of genes, which when express result in the synthesis of proteins by the cell organelles like ribosomes, rough endoplasmic reticulum.

Calculate the volume in mL of 1 mole of pure ethanol

Tamiku [17]

The units of density are g/ml. If you find the grams of 1 mol of ethanol (with the molecular weight), you can then divide by the density to get the ml of ethanol.

g*(ml/g)=ml

Nickel and carbon monoxide react to form nickel carbonyl, like this: (s)(g)(g) At a certain temperature, a chemist finds that a

horsena [70]

The question is incomplete, here is the complete question:

Nickel and carbon monoxide react to form nickel carbonyl, like this:

$Ni(s)+4CO(g)\rightarrow Ni(CO)_4(g)$

At a certain temperature, a chemist finds that a 2.6 L reaction vessel containing a mixture of nickel, carbon monoxide, and nickel carbonyl at equilibrium has the following composition:

Compound Amount

Ni 12.7 g

CO 1.98 g

$Ni(CO)_4$ 0.597 g

Calculate the value of the equilibrium constant.

Answer: The value of equilibrium constant for the reaction is 2448.1

Explanation:

We are given:

Mass of nickel = 12.7 g

Mass of CO = 1.98 g

Mass of $Ni(CO)_4$ = 0.597 g

Volume of container = 2.6 L

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Given mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}$

$\text{Equilibrium concentration of nickel}=\frac{12.7}{58.7\times 2.6}=0.083M$

$\text{Equilibrium concentration of CO}=\frac{1.98}{28\times 2.6}=0.0272M$

$\text{Equilibrium concentration of }Ni(CO)_4=\frac{0.597}{170.73\times 2.6}=0.00134M$

For the given chemical reaction:

$Ni(s)+4CO(g)\rightarrow Ni(CO)_4(g)$

The expression of equilibrium constant for the reaction:

$K_{eq}=\frac{[Ni(CO)_4]}{[CO]^4}$

Concentrations of pure solids and pure liquids are taken as 1 in equilibrium constant expression.

Putting values in above expression, we get:

$K_{eq}=\frac{0.00134}{(0.0272)^4}\\\\K_{eq}=2448.1$

Hence, the value of equilibrium constant for the reaction is 2448.1

What is a covalent bond? how does it differ from an ionic bond

horsena [70]

A covalent bond ocurs when two elements, which are usually non-metals, share electrons. an ionic bond, however, ocurs when two elements, usually a metal and a non-metal, transfer electrons. because of the transfer of electrons that occurs during ionic bonding, ionic bonds are, for the most part, much stronger, hope it helps :)
