How does salt dissolve in water?
The water molecule is polar. The oxygen and hydrogen atoms do not share the electrons equally. The larger oxygen atom tends to hold the electrons more closely than the hydrogen atoms. This causes the oxygen end of the water molecule to be slightly negatively charged, and the hydrogen atoms to be slightly positively charged. When a salt is added to water, the slightly positive hydrogen atoms attract the negative ions of the salt, and the slightly negative oxygen atom attracts the positive ions of the salt, causing them to dissociate and dissolve in the water.
What causes eggs to become rubbery?
you boil it
How do electron flow in an electric circuit in terms of voltage difference?
Electrons are negatively charged particles. When a voltage difference exists, electrons are repelled from the more negative (or less positive) voltage toward the more positive voltage. If they are in a material which allows conduction of electricity, then the electrons will flow toward the more positive voltage.
What causes liquid water to become solid ice?
When its somewhere cold that below 30oF degress
Why does water have a greater degree of surface tension than most other liquids?
Water molecules stick to each other because they can form what are called hydrogen bonds. The positively charged hydrogen atoms are attracted to the negatively charged oxygen atoms of other molecules. This stickiness means that a water molecule wants to be next to as many other water molecules as possible. so if you put something light on the surface of water, it might not be heavy enough to force the water molecules underneath it to separate.
Why is hair attracted to acetate?
Hair can become attracted to acetate due to a phenomenon called static electricity. When two materials rub against each other, electrons can transfer, causing one material to become positively charged and the other negatively charged. The attraction between the positively charged acetate and the negatively charged hair causes the static cling effect.
Why does your hair attract to a balloon when you rub a balloon on your hair?
Rubbing a balloon on your hair creates static electricity, which is generated by the friction between the balloon and hair. This static charge causes the hair strands to become positively or negatively charged, leading them to be attracted to the negatively or positively charged balloon.
What happens when something is charged by friction?
When something is charged by friction, electrons are transferred between the two objects involved in the frictional contact. This transfer of electrons causes one object to become positively charged (loses electrons) and the other to become negatively charged (gains electrons).
Why does objects become positively charged if they lose electrons?
When an object loses electrons, it becomes positively charged because it has a deficiency of negatively charged electrons compared to the positive protons in its nucleus. This imbalance of charge causes the object to have an overall positive charge.
An object becomes charged when the atoms in the object gain or lose what?
An object becomes charged when the atoms in the object gain or lose? A) protons B) neutrons C) electrons D)All of the above Answer (1) - Wrong My answer is most definitely D) All Of Above Answer (2) - Right A) and B) because if we assume an object to be neutral at first then if we lose a proton (positively charged) the object becomes negatively charged, if we lose an electron (negatively charged) the object becomes positively charged. Neutrons have no net charge (neutrally charged) so if we take on away nothing happens.
Why does a balloon repel electorns on the wall?
When a balloon is rubbed against a wall, it becomes negatively charged due to the transfer of electrons. The negatively charged balloon repels the electrons in the wall, causing the wall to become slightly positively charged. This electrostatic force between the balloon and the wall causes them to repel each other.
What is a positively charged object?
A positively charged object has an excess of protons relative to electrons. This imbalance of charge causes the object to attract negatively charged particles and repel other positively charged particles.
Why is electron for charging of a body?
Electrons carry a negative charge and are responsible for the electrical properties of atoms and molecules. When a body gains or loses electrons, it becomes positively or negatively charged. This transfer of electrons is what causes the body to become charged.
How do objects charge by contact?
Objects become charged when electrons move from object to another
When a balloon is rubbed against a cloth electrons move because?
When a balloon is rubbed against a cloth, electrons are transferred from the cloth to the balloon. This causes the balloon to become negatively charged and the cloth to become positively charged. The movement of electrons between the objects creates static electricity.
In an ionic bond the bond is caused by what?
In an ionic bond, the bond is caused by the attraction between positively and negatively charged ions. Positively charged ions (cations) are attracted to negatively charged ions (anions), resulting in the formation of the bond.
What causes an area of the inner membrane to become positively charged?
An area of the inner mitochondrial membrane becomes positively charged as a result of the electron transport chain process during cellular respiration. During this process, protons are pumped across the inner membrane, creating an electrochemical gradient with a higher concentration of protons in the intermembrane space compared to the mitochondrial matrix. This results in a positively charged intermembrane space and a negatively charged matrix.
