Answer:

Tropical rain forest environments

Explanation:

  • Albedo means whiteness is the measure of the refection of the diffused solar radiation.  And is measured from the scale of 0 to 100. Dark soil and forest have the lowest of the albedo, as they absorb the light of the sun rather than reflecting it. And snow has the highest rate of reflection of about 80%.

Work is being done in which of these situations? All motions are at a constant velocity (including velocity = zero).
tigry1 [53]

Answer:

None of the above

Explanation:

Work is defined as the force that moves an object through a particular distance:

    Workdone = force x displacement

At constant velocity, the force on a body is zero because such a body is not accelerating.  

    Force is a product of mass and acceleration. Acceleration occurs only when velocity changes with time. If no change in velocity, acceleration does not occur. Therefore, no force is being applied.

 From all the situations given, the condition is set at constant velocity. At constant velocity, there is no acceleration. This implies that no work is done.

How much energy is released when 2.72 kg of diethyl ether (C4H10O) freezes? The heat of fusion of diethyl ether is 7.27 kJ/ mol
Mama L [17]

Answer:

2672 kj

Explanation:

C4H10 O mole wt =  48 + 10 + 16 =~ 74 gm

27200 gm / 74 gm/mole = 367.57 moles

367.57 moles * 7.27 kj/mole =

With the Haber process, how many grams of hydrogen will be needed to make 0.3820 pounds of ammonia? Needed to 3 decimal places f
masya89 [10]

30.576 g of hydrogen

Explanation:

First we need to covert the pound in grams.

if        1 pound is equal to 453.592 grams

then  0.3820 pounds is equal to X grams

X = (0.3820 ×  453.592) / 1 = 173.272 grams

So we have 173.272 grams of ammonia.

Now we look at the chemical reaction where hydrogen (H₂) reacts with nitrogen (N₂) to produce ammonia (NH₃):

3 H₂ + N₂ → 2 NH₃

number of moles = mass / molar weight

number of moles of ammonia = 173.272 / 17 = 10.192 moles

Now taking in account the chemical reaction, we formulate the following reasoning:

if         3 moles of hydrogen produce 2 moles of ammonia

then    Y moles of hydrogen produce 10.192 moles of ammonia

Y = (3 × 10.192) / 2 = 15.288 moles of hydrogen

mass = number of moles × molar weight

mass of hydrogen = 15.288 × 2 = 30.576 g
