In an MRI, hydrogen atoms in the body align due to the strong magnetic field generated by the MRI machine. This magnetic field causes the protons in hydrogen atoms, which are abundant in water and fat tissues, to align with the magnetic field direction. When a radiofrequency pulse is applied, these protons are temporarily knocked out of alignment. As they return to their original alignment, they emit signals that are detected and used to create images of the body's internal structures.
What else can I help you with?
The geometry of a hydrogen-bromine molecule is?
The geometry of a hydrogen-bromine molecule is linear. This means that the hydrogen and bromine atoms are arranged in a straight line with a bond angle of 180 degrees.
What type of bond is shown by the solid line between the two hydrogen?
The solid line between the two hydrogen atoms represents a covalent bond. This type of bond occurs when two atoms share one or more pairs of electrons, allowing them to achieve greater stability. In the case of hydrogen, each atom shares one electron, forming a diatomic hydrogen molecule (Hâ‚‚).
What is hydrogen bromide's molecular shape?
Hydrogen bromide's molecular shape is linear. It consists of two atoms, hydrogen and bromine, that are arranged in a straight line with a bond angle of 180 degrees.
What causes the regions of charge polarity on water?
Water molecules contain two polar ends known as dipoles which are caused by the atoms that make up water. The chemical composition of water is H20 meaning that there are 2 hydrogen atoms bound to one oxygen atom. This bonding does not occur in a straight line and the bond angle between the 2 hydrogen atoms is 109 degrees and 27-28 minutes I believe. The hydrogen Atoms have a positive charge while the oxygen atoms have a negative charge which helps to hold the atom together (along with hydrogen bonding). If you look at a diagram of the structure of water, you will see that the hydrogen atoms are more on one side of the molecule while the oxygen is on the other. this makes one side slightly positive while the other side becomes slightly negative
Does the line spectrum of water vapor bear any resemblance to the line spectra of hydrogen and oxygen?
Yes there will be. This is because when you take line spectrum of water vapor, then hydrogen and oxygen atoms will form their own line spectra and the final spectrum will be a combination of the two.
What do the lines between atoms mean?
A dashed line represents a hydrogen bond because they are the weakest of the bonds.
What is a saturated fat saturated with?
Saturated fats are saturated with hydrogen atoms.
What type of dot structure does CH4 have?
CH4 has a tetrahedral dot structure, with a carbon atom in the center bonded to four hydrogen atoms, each represented by a line. The four hydrogen atoms are evenly spaced around the carbon atom at the corners of the tetrahedron.
Which molecules have three atoms that do not fall in a straight line?
One example of a molecule with three atoms that do not fall in a straight line is water (H2O). The two hydrogen atoms are bonded to the oxygen atom, creating a bent shape due to the electron pairs on the oxygen atom.
What does the hexane molecule look like?
Hexane is C6H14 and looks like 6 carbon atoms strung in a zigzag line with 2 hydrogen atoms attached at each carbon and an endcap hydrogen atom each at the ends of the chain.
How can one effectively read bond line structures?
To effectively read bond line structures, start by identifying the carbon atoms as the corners and the hydrogen atoms attached to them. Then, focus on the lines representing bonds between atoms. Pay attention to the arrangement of atoms and bonds to understand the molecular structure. Practice and familiarity with common bond line structures will improve your ability to interpret them accurately.
Why are the hydrogen Balmer lines strong in the spectra of medium-temperature stars and weak in the spectra of hot and cool stars?
They are like this due to the fact that most hydrogen atoms are ionized which makes a weaker balmer line. The strength of the Balmer line is sensitive to temperature so that's why it occurs more in the middle. The hot end of the hydrogen is low Balmer line due to them being in the ground state. Hope that's answers it =] -CRS
