storchak [24]

Answer:

The term “flat bone” is somewhat of a misnomer because, although a flat bone is typically thin, it is also often curved. Examples include the cranial (skull) bones, the scapulae (shoulder blades), the sternum (breastbone), and the ribs. Flat bones serve as points of attachment for muscles and often protect internal organs.

3. A student carries out the clay-catalyzed dehydration of cyclohexanol starting with 10 moles of cyclohexanol and obtains 500 m
IrinaK [193]

Answer:

49.45~%

Explanation:

In this case, we have to start with the <u>chemical reaction</u>:

C_6H_1_2O~->~C_6H_1_0~+~H_2O

So, if we start with <u>10 mol of cyclohexanol</u> (C_6H_1_2O) we will obtain 10 mol of cyclohexanol (C_6H_1_0). So, we can calculate the grams of cyclohexanol if we<u> calculate the molar mass:</u>

(6*12)+(10*1)=82~g/mol

With this value we can calculate the grams:

10~mol~C_6H_1_0\frac{82~g~C_6H_1_0}{1~mol~C_6H_1_0}=820~g~C_6H_1_0

Now, we have as a product 500 mL of C_6H_1_0. If we use the <u>density value</u> (0.811 g/mL). We can calculate the grams of product:

500~mL\frac{0.811~g}{1~mL}=405.5~g

Finally, with these values we can calculate the <u>yield</u>:

%~=~\frac{405.5}{820}x100~=~49.45%%= (405.5/820)*100 = 49.45 %

See figure 1

I hope it helps!

An ice cube at 0.00 ∘C∘C with a mass of 21.5 gg is placed into 500.0 gg of water, initially at 31.0 ∘C∘C, in an insulated contai
4vir4ik [10]

Answer:

The temperature of the entire water sample after all of the ice has melted is 31.4 °C

Explanation:

This question relates to the first law of thermodynamics which states that energy can not be created nor destroyed but changes from one form to another

The specific heat capacity of water is 4.2 J/(g °C)

The latent heat of fusion of ice = 333.55 J/g

Mass of the ice = 21.5 g

Mass of the water = 500 g

Initial temperature of water = 31 °C

Therefore

Heat gained by the ice = 21.5 g × 333.55 J/g = 7162.725 J

= 500×4.2×(T-31)

Or T = 31.4 °C

Therefore the temperature of the entire water sample after all of the ice has melted is 31.4 °C
