a sample of tin is heated until it finishes melting. the sample absorbs a total of 1050 j of heat. if the sample requires 460 j of heat to reach its melting point, how much heat is needed to completely melt the sample of tin?
The heat of fusion is the amount of heat energy needed to turn anything solid into a liquid. There is a formula, Q = mHf. Because matter doesn't affect temperature, the temperature is not a factor.
Will the addition of heat cause the temperature to rise during a phase change?There is no increase in the kinetic energies of the particles, and hence no rise in temperature, because the energy required for phase shifts is employed to break bonds. Similarly, energy is required to evaporate a liquid to defeat the attraction forces between the liquid's particles.
Does the temperature drop when a phase shift occurs?The energy that is given during a change in the state of matter is used to alter the binding energies rather than boost the kinetic energy of the molecules. As a result, the temperature doesn't change.

consider the reaction below. h2s so2−4⇌hs− hso−4 which of the above chemical species is the brønsted-lowry base in the forward reaction?
HS is the Bronsted-Lowry base in the forward reaction.
The Brnsted-Lowry theory is an acid-base reaction theory that was independently proposed in 1923 by Johannes Nicolaus Brnsted and Thomas Martin Lowry.
An acid is a proton (H+) donor in the Brnsted-Lowry definition of acids and bases, and a base is a proton acceptor. A conjugate base is formed when a Brnsted-Lowry acid loses a proton. A conjugate acid is formed when a Brnsted-Lowry base gains a proton.
A Bronsted-Lowry base is a compound that accepts a proton or an H+ ion from another compound. A conjugated acid can donate a proton and reform the base. An acid-base reaction, according to the Bronsted-Lowry theory, involves the exchange of protons or H+ ions between the acid and base.

The procedures tells a student to measure 7.55 ml of solution 1 but the student measures 11.89 ml of solution 1. The percent by volume of extra liquid measure by the student added is 36.50%.
The percent by volume for any solution is calculated as

In the given problem, the volume of solution is 11.89 ml and the volume of the solute is
volume of solute=(11.89-7.55)ml
volume of solute=4.34ml
We cannot consider the volume used to measure by procedure because the total volume is increased by extra addition of the solute. Plug all values in the formula
%(v/v)=(4.34 ml/11.89 ml)×100
%(v/v)=0.36501×100

Cholinergic synapse is a type of chemical synapse that uses acetylcholine (ACh) as its neurotransmitter. This type of synapse is found in the peripheral and central nervous systems and is responsible for the transmission of signals between neurons and other cells. The following steps are involved in cholinergic synapse:
a. Release of Acetylcholine: Neurotransmitter Acetylcholine is released from the presynaptic neuron into the synaptic cleft. This release is regulated by calcium ions and the neurotransmitter is packaged into vesicles which are then transported to the release sites.
b. Binding of ACh to receptors: The released ACh diffuses across the synaptic cleft and binds to postsynaptic receptors on the target cell. This binding triggers a cascade of events in the target cell.
c. Postsynaptic responses: The binding of ACh to postsynaptic receptors triggers a variety of responses in the target cell. These responses include the opening of ion channels, the release of additional neurotransmitters, and the activation of second messenger systems.
d. Inactivation of ACh: After the postsynaptic responses have been carried out, the ACh molecule is inactivated by acetylcholinesterase (AChE). This enzyme breaks down ACh into its component parts, which are then recycled or degraded.
e. Reuptake of ACh: The released ACh is also taken up by the presynaptic neuron for reuse. This process is known as reuptake and helps to regulate the amount of ACh in the synaptic cleft.
By following these steps, the cholinergic synapse is able to transmit signals from one neuron to another. This process is essential for the normal functioning of the nervous system.
