If you have 1.4 grams of silver (Ag), how many moles of silver do you have?
creativ13 [48]

Answer: There are 0.0129 moles of silver present in 1.4 grams of silver (Ag).

Explanation:

Given: Mass of silver = 1.4 g

Number of moles is the mass of substance divided by its molar mass.

As molar mass of silver is 107.86 g/mol. Therefore, moles of silver are calculated as follows.

No. of moles = \frac{mass}{molar mass}\\= \frac{1.4 g}{107.86 g/mol}\\= 0.0129 mol

Thus, we can conclude that there are 0.0129 moles of silver present in 1.4 grams of silver (Ag).

Discuss how you can represent a chemical reaction using a system of linear equations. Use the chemical reaction from your projec
Dmitry [639]

Answer:

KOH + H_2SO_4 \rightarrow K_2SO_4 + H_2O

Explanation:

A chemical reaction describes the reaction between reactants to produce products.

A chemical equation is represented as a reactant present on the left-hand side of the equation if two or more reactants are present they are separated by the "plus" sign.

On the right side of the equation product is written and if more than one product is formed then these are separated by "plus" sign as in the reactants.

The reactant and the products are separated by an arrow, the head of arrow is in the direction of the product when the reaction is irreversible.

In the case of reversible reactions or chemical reactions that are present in equilibrium, the reactant and product are separated by a double-headed arrow.

If electrons are collectively compressed into a very small volume (e.g., within the core of a dying white dwarf star) where quan
m_a_m_a [10]

Answer:  A degenerate pressure will generate a large force to repel further  compression.

Explanation: In the production of new stars from the core of old dying white dwarf stars, the inner parts of the star will experience contraction with the release of  heat , as they contract, their atoms will be  squeezed such that their electrons start to overlap, and because of the Pauli's exclusive principle which states that no two electrons can occupy same space, the electrons will begin to repel each other and an opposing pressure called degenerate pressure will create a force so that the electrons  cannot continually be crushed or overlap. With the limit of contraction, the outer parts of the star will expand and be repelled releasing the old stars called nebula  and creating space for the inner new stars to form.

Determine the change in entropy for 2.7 moles of an ideal gas originally placed in a container with a volume of 4.0 L when the c
olchik [2.2K]

Answer:

The value of entropy change for the process dS = 0.009 \frac{KJ}{K}

Explanation:

Mass of the ideal gas = 0.0027 kilo mol

Initial volume V_{1} = 4 L

Final volume V_{2} = 6 L

Gas constant for this ideal gas ( R ) = R_{u}  M

Where R_{u} = Universal gas constant = 8.314 \frac{KJ}{Kmol K}

⇒ Gas constant R = 8.314 × 0.0027 = 0.0224 \frac{KJ}{K}

Entropy change at constant temperature is given by,

dS = R  log _{e} \frac{V_{2}}{V_{1}}

Put all the values in above formula we get,

dS = 0.0224  log _{e} [\frac{6}{4}]

dS = 0.009 \frac{KJ}{K}

This is the value of entropy change for the process.
