Hemoglobin is the protein responsible for transporting O2 throughout the body. Each molecule of hemoglobin combines with four mo

lecules of O2. If 1.22 g of hemoglobin combines with 1.53 mL of O2 at 37 °C and 743 torr, what is the molar mass of hemoglobin based on this experiment?

How do structures stand up under a load
shusha [124]

Answer:

The force then channels down through the walls to the floor. The force of the walls pushing down on the floor is exactly balanced by an equal force when the floor pushes up on the wall. ... The main, structural walls are called load-bearing walls and they're usually built from solid brick or stone.

Which boiling point is lower an why?
DiKsa [7]

Answer:4

Explanation:

If we carefully observe the electronegativity of the elements in question

P-2.19

N-3.04

C-2.55

Si-1.9

H-2.2

SiH4 is definitely more polar than CH4 hence greater dipole forces of a higher boiling point. NH3 is more polar than PH3 hence NH3 has greater dipole forces and a higher boiling point. Electronegative differences influences the polarity of a bond. The greater the electro negativity difference between bonding atoms, the greater the dipole forces and the greater the boiling point.

Answer:

1. First one is true : as per periodic table down the group , the elements has increasing order of shell & with that the London dispersion forces brings the inter-molecules close together and bromine converted into liquid .

2. second one is False  because carbon-carbon bonds are not weak bonds they form mutual covalent bonds which are stronger bonds and cannot be easily disrupted .

3. A single carbon atom has the valency of 4 so it can be bonded with four hydrogen atom at the same time .

What is 30-9x2*2-21-4+4
IgorC [24]
Answer:
9 (1-2x²)

Explanation:
The given expression is:
30 - 9x²*2 - 21 - 4 + 4
The first step is to compute the multiplication. This will give:
30 - 18x² - 21 - 4 + 4
Then, we will add like terms as follows:
(30-21-4+4) - 18x²
= 9 - 18x²
Finally, we can take the 9 as a common factor from both terms, this will give:
9 (1-2x²)

Hope this helps :)
