Answer:

The kidneys, although the liver is involved in hemoglobin breakdown. The liver is not an excretory organ, so it is the kidneys which break down red blood cells and produces urea, but that urea is not just from blood cells. In fact, hardly any of it is. Urea is largely composed of nitrogenous wastes given off by cells, and ammonia is NH3. Hope This Helps.

Fe2O3+2Al=Al2O3+2Fe

True [87]

We determine the limiting reactant by using the moles present in the equation and the actual moles.
According to equation, ratio of Fe₂O₃ : Al = 1 : 2
Actual moles of Fe₂O₃ = 187.3 / (56 x 2 + 16 x 3)
= 1.17
Actual moles of Al = 94.51 / 27
= 3.5
Fe₂O₃ is limiting. Fe₂O₃ required:
(moles Al)/2 = 3.5/2 = 1.75
Moles to be added = 1.75 - 1.17
= 0.58
Mass to be added = moles x Mr
= 0.58 x (56 x 2 + 16 x 3)
= 92.8 grams

The atmospheric pressure at 2000m altitude is 560. mmHg. What is the atmospheric pressure in atm? atm

Lostsunrise [7]

This problem is providing the atmospheric pressure at 2000 m altitude which is 560. mmHg and asks for this pressure in units of atmospheres, which after doing the calculations, the result is 0.737atm.

<h3>Atmospheric pressure:</h3><h3 />

In this case, we can firstly define the concept of atmospheric pressure, also known as barometric pressure, as that pressure exerted by a column of air over a specific point in space at a defined altitude.

<h3>Units conversion in pressure:</h3><h3 />

In order to get the correct conversion, we use the following equivalence statement relating mercury millimeters and atmospheres:

760 mmHg = 1 atm

Hence, the required conversion turns out to be:

$560.mmHg*\frac{1atm}{760mmHg}=0.737atm$
