Metals such as iron, lead, copper, and zinc have relatively ___ specific heats. This means it takes ___ energy to chan thejr tem
ivann1987 [24]

B. Low; very little

Explanation:

Metals such as iron, lead, copper and zinc have low specific heats. This means that it takes very little energy to change their temperature.

Specific heat is the heat required to raise the temperature of 1g of substance by 1°C.

Metals have good thermal conductivity and generally have low specific heat. This implies that their temperature can easily be raised when heated.

Some substances like water have very high specific heat. This suggests that they require more heat to raise their temperature.

What is the mass, in g, of 27.2 mol of N? Be sure to answer all parts. Enter your answer in scientific notation. x 10 (select) A
svp [43]

Explanation:

It is known that number of moles of a substance equal to mass divided by its molar mass.

Mathematically,         No. of moles = \frac{mass}{\text{molar mass}}

It is given that no. of oles present are 27.2 mol and molar mass of N is 14 g/mol.

Therefore, calculate mass of N as follows.

                 No. of moles = \frac{mass}{\text{molar mass}}

                       27.2 mol = \frac{mass}{14 g/mol}

                      mass = 380.8 g

Thus, we can conclude that mass of N is 380.8 g.

Which is an example of maintaining structure?
Murrr4er [49]

Answer: healing a wound

Explanation:

The healing of the wound is the example of maintenance of the structure. The wound is the injury which disturbs the continuity of the skin surface. It can affect the dermal and epidermal layer of the skin. The wound if severe or deep can damage the bones. The wound can be caused by the cut, blow or punch, impact or fall from height. The healing of the wound may take several days to weeks. The wound healing involves the replacement of the damaged or destroyed cells or tissues by new cells or tissues in the body or the wound site.
