Halogens are good leaving groups in substitution reactions because leaving group ability is directly related to their being:____

_____
a. weak bases
b. strong bases
c. strong acids
d. electrophiles

Answer:

weak bases

Explanation:

Leaving groups accept electron pairs. A strong base donates an electron pair while a weak base accepts an electron pair.

Since good leaving groups must readily accept electrons, weak bases are very good leaving groups.

The order of usefulness of halogens as leaving groups is: I > Br > Cl > F

Answer:

1. 25 moles water.

2. 41.2 grams of sodium hydroxide.

3. 0.25 grams of sugar.

4. 340.6 grams of ammonia.

5. 4.5x10²³ molecules of sulfur dioxide.

Explanation:

Hello!

In this case, since the mole-mass-particles relationships are studied by considering the Avogadro's number for the formula units and the molar mass for the mass of one mole of substance, we proceed as shown below:

1. Here, we use the Avogadro's number to obtain the moles in the given molecules of water:

1.5x10^{25}molecules*\frac{1mol}{6.022x10^{23}molecules} =25 molH_2O

2. Here, since the molar mass of NaOH is 40.00 g/mol, we obtain:

1.2mol*\frac{40.00g}{1mol} =41.2g

3. Here, since the molar mass of C6H12O6 is 180.15 g/mol:

45g*\frac{1mol}{180.15g}=0.25g

4. Here, since the molar mass of ammonia is 17.03 g/mol:

20mol*\frac{17.03g}{1mol}=340.6g

5. Here, since the molar mass of SO2 is 64.06 g/mol:

48g*\frac{1mol}{64.06g} *\frac{6.022x10^{23}molecules}{1mol} =4.5x10^{23}molecules

Best regards!

As the temperature of a gas sample increases, the number of molecules and volume remaining constant, the pressure exerted by the
Luba_88 [7]

Answer:

A. increases

Explanation:

According to the Gay-Lussac's law:-

Thus, at constant volume and number of moles, Pressure of the gas is directly proportional to the temperature of  the gas.

P ∝ T

Also,  it can be written as:-

\frac {P_1}{T_1}=\frac {P_2}{T_2}

Thus, if the temperature is increased, the pressure exerted by the gas also increases.
