Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out
Answer is true hope I helped!
We'll make this a bit simpler.
1 mile = 1.60934km
90.0 million miles.
9.0 x 10^7 miles * (1.60934km / 1 mile) * (1000m / 1km) = 7.70x10^79 m
Answer:
1.12x10²³ atoms of F
Explanation:
A molecule is a group of 2 or 3 atoms that are bonded by electrostatic charges.
In 1 molecule of MgF2 there are 2 atoms of fluorine and 1 atom of magnesium.
Thus, there are 2 atoms of fluorine per molecule of MgF2. In 5.6x10²² molecules:
5.6x10²² molecules MgF2 * (2 atoms Fluorine / 1 molecule MgF2) =
<h3>1.12x10²³ atoms of F</h3>
Matrix-derived protons are translocated across the mitochondrial membrane by altering pKa values of functional groups located on the inner and outer faces of the membrane.
<u>Explanation:</u>
The translocation of protons occurs across the inner mitochondrial membrane by two mechanisms. This dislocation occurs with the electron transport system protein complexes. The two mechanisms are described below.
First one is the redox loop mechanism. In this mechanism a redox reaction takes place. The separation of H+ and e- thereby resulting in the electron transport system protein. The opposite side of inner mitochondrial membrane is the place where it gets deposited.
Next one is the proton pump mechanism. Here the translocation of matrix-derived protons take place on the inner mitochondrial membrane . this takes place with the alteration of pKa values of functional groups that have the location the inner and outer faces of the membrane.
