Compare and contrast Mercator and conic projections

Artemon [7]

Mercator and conic projections are different because conic projections have a cone/triangle shape and Mercator projections have a cylindrical look to them. They are both the same because they show the world. However, the world is viewed from very different perspectives. For example, a Mercator projection is from the point of view of a bird and the conic is from a view from space.

Identify the type or types of intermolecular forces present between molecules of the compound pictured below:

Dennis_Churaev [7]

Answer:

dispersion, dipole-dipole, and hydrogen bonding

Explanation:

The pictured compound is an amine. Amines have high boiling points. Amines have such high boiling points because they posses about three different kinds of intermolecular interactions, viz; hydrogen bonds, dispersion forces and dipole-dipole interactions.

The dipole interactions and hydrogen bonds arise from the fact that the N-H bond is polar. Also recall that a hydrogen bond is formed when hydrogen is bonded to an electronegative element. Hydrogen bonds lead to significant intermolecular association and high boiling points.

Hence the three kinds of intermolecular forces present in the pictured compound are; hydrogen bonding, dipole interactions and dispersion forces.

A piece of copper (12.0 g) is heated to 100.0 °C. A piece of chromium (also 12.0 g) is chilled in an ice bath to 0 °C. The speci

Gennadij [26K]

Answer:

(a) Slightly greater than 20.0 °C

(b) $T_F=293.46K=20.3^oC$

Explanation:

Hello,

In this case, since we are talking about the equilibrium temperature that will be reached when the copper, chromium and water samples get in contact, the following equation is useful to describe such situation:

$\Delta H_{water}+\Delta H_{copper}+\Delta H_{chromium}=0\\$

Thus, in terms of masses, heat capacities and temperatures we consider the final temperature as the unknown:

$m_{water}Cp_{water}(T_F-T_{water})+m_{copper}Cp_{copper}(T_F-T_{copper})+m_{chromium}Cp_{chromium}(T_F-T_{chromium})=0$ In such a way, by knowing that the heat capacities of copper and chromium are 0.386 and 0.45 J/(g°C) respectively, by solving for the equilibrium temperature one has:

$T_F=\frac{m_{water}Cp_{water}T_{water}+m_{Cu}Cp_{Cu}T_{Cu}+m_{Cr}Cp_{Cr}T_{Cr}}{m_{water}Cp_{water}+m_{Cu}Cp_{Cu}+m_{Cr}Cp_{Cr}}$

$T_F=\frac{200.0g*4.184\frac{J}{g*K}* 293.15K+12.0g*0.386\frac{J}{g*K} *373.15K+12.0g*0.45\frac{J}{g*K}*273.15K}{200.0g*4.184\frac{J}{g*K}+12.0g*0.386\frac{J}{g*K} +12.0g*0.45\frac{J}{g*K}}\\\\T_F=293.46K=20.3^oC$

Hence, the resulting temperature of water turns out slightly greater than 20.0 °C.

Best regards.
