Extrusive Rocks. Igneous rocks which form by the crystallization of magma at the surface of the Earth are called extrusive rocks. They are characterized by fine-grained textures because their rapid cooling at or near the surface did not provide enough time for large crystals to grow.

A jeweler is making sapphire rings using 2 sapphires on every 1 ring. If the jeweler has 12 sapphires and 10 rings, what is the
user100 [1]

Answer: The theoretical yield is 6 rings.

Explanation:

Theoretical yield is predicted or estimated value.

Jeweler used 2 sapphires for 1 ring

Then for each sapphire there will be = \frac{1}{2} rings are used

For 12 sapphire = \frac{1}{2}\times 12=6 rings will be used

Out of 10 rings 6 rings with 2 sapphires will be made.

The theoretical yield is 6 rings.

Consider the aldol-dehydration reaction. Draw the two possible products of the reaction between benzaldehyde and methylethylketo
Dafna1 [17]

Solution :

An $\text{aldol condensation}$ reaction is a type of \text{condensation reaction} in organic chemistry where the enol or an enolate ion reacts with the carbonyl compound and forms a $\beta$-hydroxyaldehyde or a $\beta$-hydroxyketone, and then followed by a dehydration to give conjugated enone.  

Benzaldehyde reacts with methylketone and forms two products:

What will happen to convection currents in the mantle if earths interior eventually cools down?
VLD [36.1K]
If the core were to cool completely, the planet would grow cold and dead. It also would get a little dark: Power utilities pull radiant heat from Earth's crust and use it to heat water, the steam from which powers turbines to create electricity.Cooling also could cost us the magnetic shield around the planet created by heat from the core. This shield protects Earth from cosmic radiation. The shield is created by a convection process caused by constantly moving iron. Like the planet itself, Earth's core is constantly spinning. Some scientists think it's moving even faster than the rest of the planet. The friction converts kinetic energy into electrical and magnetic energy that forms the field, which deflects harmful, charged particles emanating from the sun toward the north and south poles. Your welcome :)
