Brass is an alloy, or a combination of two (or more) metals.
Answer:
Both are chemical changes.
Explanation:
They are chemical changes because when when you melt the sugar to make caramel a new substance is formed. The same with cookies. You don't start out with cookies, you start out with dough. And then when you cook the dough a new substance is formed which is the cookies.
Excess alcohol is removed by Vacuum filtration.
<h3>What is vacuum filtration?</h3>
- Vacuum filtration is a methodology where a tension differential is kept up with across the channel medium by clearing the air beneath the channel paper.
- Vacuum filtration gives a power on the arrangement notwithstanding that of gravity and builds the pace of filtration.
- Vacuum filtration is the standard strategy utilized for isolating a strong fluid blend when the objective is to hold the strong (for instance in crystallization).
<h3>How do you dry a product after vacuum filtration?</h3>
- The strong can be dried rapidly by washing the strong with an unpredictable fluid (methanol, CH3)2CO, or ether are normal) that the strong won't break up in. In the event that the filtrate is to be gathered, change the getting jar prior to washing.

One can expect to find the greatest amount of hydrolyzed pth when, entering the nephrons.
<h3><u>
Where would one expect to find the greatest amount of hydrolyzed pth ?</u></h3>
- In a healthy person, the body will respond by excreting calcium and PTH byproducts if plasma calcium is higher than usual. The nephron is a solid predictor since the kidneys are where excretion takes place.
- A) is false since PTH, not the hydrolyzed compounds, is produced by the parathyroid gland.
- One would anticipate significant amounts of PTH exiting the liver rather than entering since the liver hydrolyzes PTH.
- The largest concentration would still be in the nephrons, even if it is possible that some hydrolysis products will be in systemic circulation (and therefore penetrate the bones).
- The cortical bone, which is the outermost part of the bone, has a network of small tubes called haversian canals that let blood vessels and nerves to pass through them.

Two alkaline earth metals; Be and Mg exhibit a diagonal relationship. The pair of elements are Be-Al and Mg-Li is Be-Al and Mg-Li.
Six elements make up the majority of alkaline earth metals (Group 2): beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). Compared to the elements in Group 1, this group typically contains smooth, silver metals with a less metallic character. Heavy metals like Ca, Sr, Ba, and Ra are equally as reactive as Alkali Metals Group 1 despite sharing many characteristics with that group. All elements found in alkaline earth metals contain two electrons in their valence shells, giving them an oxidation state of +2. This makes it possible for metals to shed electrons with ease, allowing them to create compounds with more stable ionic connections.
