Answer:

The Art of Protein Synthesis

In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.

Match each term with its definition.

padilas [110]

Answer:

The position of an equilibrium always shifts in such a direction as to relieve a stress applied to the system -Le Chåtelier's principle

A molecule that donates a proton when it encounters a proton acceptor.- Bronsted-Lowry acid

Occurs when a reaction involving an acid and its conjugate base is combined with a second reaction involving a base and its conjugate acid.- Neutralization

It ionizes completely when dissolved in water.- Strong acid

The shift in the position of equilibrium caused by the addition of a participating ion.- Common ion effect

It only partially ionizes when dissolved in water.- Weak electrolyte

It is capable of acting as either an acid or a base depending upon the solute- Amphoteric solvent

The act of self-ionization of a solvent to produce both a conjugate acid and a conjugate base.- Auto-protolysis

A chemical species that bears both positive and negative charges.- Zwitterion

Explanation:

In the answer box we have various chemical terminologies and their definitions. In answering the question, you must carefully read through each definition, then check what option best matches that definition from the options provided.

Each definition applies only to one terminology as you can see in the answer above.

Malic acid, C4H6O5, has been isolated from apples. Because this compound reacts with 2 molar equivalents of base, it is a dicarb

Flura [38]

Answer and explanation:

The attached figure shows five different structures for the chemical formula C4H5O5, but only one of these structures represent the malic acid.

Malic acid is a dicarboxylic acid, this means malic acid has two

-COOH groups. Also, malic acid is a secundary alcohol, which means it has a R2-C-OH group.

-Structure A has two carboxylic groups, but it doesn´t have a secundary alcohol.

-Structure B doesn´t have any caborxylic group.

-Structure C has two carboxylic groups and it is a secundary alcohol. Structure C is the Malic acid

Given 5.0 grams of lead (II) nitrate and 3.0

natulia [17]

Answer:

1.70 g of NaNO₃

Explanation:

The balance chemical equation for given double displacement reaction is,

Pb(NO₃)₂ + 2 NaI → PbI₂ + 2 NaNO₃

Step 1: Calculate moles of each reactant:

Moles = Mass / M.Mass

For Pb(NO₃)₂:

Moles = 5.0 g / 331.21 g/mol

Moles = 0.0150 moles

For NaI:

Moles = 3.0 g / 149.89 g/mol

Moles = 0.020 moles

Step 2: Calculate Limiting reagent as;

According to equation,

1 mole of Pb(NO₃)₂ reacts with = 2 moles of NaI

So,

0.0150 moles of Pb(NO₃)₂ will react with = X moles of NaI

Solving for X,

X = 2 mol × 0.0150 mol / 1 mol

X = 0.030 moles of NaI

Hence, it means that NaI is the limiting reagent therefore, it will control the yield of Sodium Nitrate.

Step 3: Find out moles of NaNO₃ formed:

According to equation,

2 mole of NaI produced = 2 moles of NaNO₃

So,

0.020 moles of NaI will produce = X moles of NaNO₃

Solving for X,

X = 2 mol × 0.020 mol / 2 mol

X = 0.020 moles of NaNO₃

Step 4: Calculate Mass of NaNO₃ produced;

As, Moles = Mass / M.Mass

Or,

Mass = Moles × M.Mass

Putting values,

Mass = 0.020 mol × 84.99 g/mol

Mass = 1.70 g of NaNO₃
