tankabanditka [31]

Answer:

High partial pressure of oxygen in the tissues.

Explanation:

Hemoglobin is a protein found in the red blood cells that is responsible for the transportation of oxygen from the lungs to the rest of the tissues in the body. The partial pressure determines whether oxygen is loaded or unloaded into the hemoglobin.

When there is lack of oxygen in our bodies, we experience hypoxia.

What is the balanced equation for the production of water?
Bess [88]

Answer:

H₂ + O₂ → H₂O

Now, check that oxygen has two atoms on the left and one on the right

so, you put 2 on the right side

H₂ + O₂ → 2H₂O

oxygen is balanced so, add 2 on H₂ to balance out hydrogen

THE FINAL BALANCED EQUATION:

<h2>2H₂ + O₂ → 2H₂O</h2>

What is the specific heat of ethanol if 4650 j are required to raise the temperature of 250.0g of ethanol from 22.0oc to 29.6 de
Alchen [17]

Answer:

C=2.45\frac{J}{g\°C}

Explanation:

Hello there!

In this case, since the thermodynamic definition of heat in terms of mass, specific heat and temperatures is given by:

Q=mC(T_2-T_1)

We are to calculate the specific heat of the ethanol as shown below:

C=\frac{Q}{m(T_2-T_1)}

Thus, by plugging it the given data we can obtain:

C=\frac{4650J}{250.0g(29.6-22.00\°C)} \\\\C=2.45\frac{J}{g\°C}

Regards!

Presence of Oxygen in mitochondria is called Aerobic conditions and under this aerobic conditions Pyruvic acid is converted into Acetyl Co.A which enters Krebs' cycle
while in absence of oxygen which called Anaerobic conditions pyruvic acid is converted into Lactic acid to avoid accumulation of NADH⁺ which inhibit glycolysis and provide NAD⁺ required for glycolysis

Be sure to answer all parts. Determine the electron-group arrangement, molecular shape, and ideal bond angle for the following m
choli [55]

Answer:

trigonal planar

Explanation:

The molecule SO3 is of the type AX3. The molecule is symmetrical and non polar.

There are three regions of electron density in the molecule. This corresponds to a trigonal planar geometry. This means that the three oxygen atoms are arranged at the corners of a triangle.  The bond angle is 120 degrees.
