The Heck reaction is a coupling reaction that combines an unsaturated halide with an alkene in the presence of base and palladium catalyst to provide a substituted alkene. It an important reaction as it forms a carbon-carbon bond and allows substitution on sp² hybridized carbons.

In this example, we have bromobenzene reacting with propene and are told that two constitutional isomers are formed. The expected product is the first one shown which has the benzene substitute onto the terminal end of the alkene. The isomer by-product that is formed is substitution onto the central carbon of the propene which leads to a product with a terminal alkene.

Determine the expression for the equilibrium constant, kc, for the reaction by identifying which terms will be in the numerator
MakcuM [25]

The kc is a representation of how fast the reaction proceeds to their products when it has achieved equilibrium. The activation energy for the forward and the one for the reverse reaction are similar because they attained chemical equilibrium. A chemical equilibrium happens when both of the reactant and products achieve the same concentration. An example is the process of melting and freezing. Melting and freezing for a given substance occurs at the same temperature. Because the temperature at which the solid starts to melt is also the temperature at which the liquid starts to freeze. They are at chemical equilibrium.

True or False: Water molecules "stick together" due to hydrogen bonds.
Dimas [21]

Answer:

True

Explanation:

To begin with,

Hydrogen bonds are attractions that contain a force caused by the difference in charge. This is due to the positive hydrogen ions as well as  slightly negative ions. Therefore, hydrogen bonds make water molecules 'sticky.' To add, the attractions between hydrogen bonds are weaker than ionic and covalent bonds but strong enough to cause them to 'stick together'

Hope this helps.

To insert a thermometer into an adapter, use ______ to prepare the thermometer. Then, hold the thermometer ______ the adapter an
Sati [7]

Answer:

mineral oil; close to; slowly turn

Explanation:

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

Generally, temperature measures the average kinetic energy of particles in a particular substance.

A thermometer can be defined as a device used for measuring the temperature (degree of hotness or coldness) of a body or substance is. It is a thin glass having a bulb on one of its end and typically contains either colored alcohol or mercury.

A thermometer adapter is used with a temperature probe in the distillation process, in order to determine readings.

To insert a thermometer into an adapter, use mineral oil to prepare or make suitable the thermometer. Then, hold the thermometer close to the adapter and slowly turn the thermometer into the adapter.
