Which phrase is an example of what electrostatic forces hold together?
Andreyy89

Answer:

Cs+ and Cl− in CsCl is an example of electrostatic forces that hold together.

Explanation:

The interaction that occurs between atoms that have an electric charge is called electromagnetic force. When the charges are at rest, the interaction between them is called electrostatic force. This force depends on the distance "r" between the atoms.

Depending on the sign of the charges that interact, electrostatic force can be attractive or repulsive. The electrostatic interaction between charges of the same sign is repulsive (two negative charges or two positive charges), while the interaction between charges of the opposite sign (a negative charge and a positive charge) is attractive. In the case of neutral charges against negative or positive charges, no force is generated.

<u><em>Cs+ and Cl− in CsCl is an example of electrostatic forces that hold together. </em></u>In this example you have a positively charged atom (Cs₊) and a negatively charged atom (Cl₋). As they are opposite charges they will attract.

A reaction between liquid reactants takes place at in a sealed, evacuated vessel with a measured volume of . Measurements show t
Semmy [17]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The pressure is  P  = 0.76 \ atm

Explanation:

From the question we are told that

   The mass of the carbon monoxide  is  m_c  =  17 \ g

   The temperature at which takes place  T  = 30 .0^oC =  30 + 273 =  303 K

   The volume of the sealed vessel  is  V  =  20 .0L

Generally the ideal gas law is mathematically represented as

        PV  =  nRT

Where R is the gas constant with value  R =  0.0821  \ L \ atm \ mol^{-1} K^{-1}

n is the number of moles of carbon monoxide  which is mathematically evaluated as

             n =  \frac{m_c}{M_c}

where M_c is the molar mass of carbon monoxide which is a constant with value

        M_c  =  28 \ g/mol

So     n  =  \frac{17}{28}

         n  =0.6071

Now Making P the subject we have

           P  =\frac{ 0.6071 * 0.0821 * 303}{20}

           P  = 0.76 \ atm

The inhibition caused by the final end product of a reaction is called
Troyanec [42]

Answer:

Non competitive inhibition

Explanation:

Hello,

During enzymatic catalysis, the active sites could be occupied by the very same products' molecules turning out into an inhibition (the reaction starts to slow down since to active places are available for the reagents to react). Nonetheless this inhibition is not competitive as long as the product does not react due to the active sites it is occupying.

Best regards.
