Potassium, sodium, and lithium will rapidly react with air, ruining the sample and will react violently with water, creating a fire hazard. The oil keeps the metals out of contact with air and moisture.
An empty bottle is typically lightweight, has no liquid inside, and makes a hollow sound when tapped. It may also have a lingering odor of whatever liquid was previously stored in it.
The orange color of potassium dichromate is caused by the movement of an electron to a vacant d-orbital in the manganese atom. The transition occurs when the chemical is in the presence of light. This is confirmed by the empty 3d-orbital in chromium.
This may be trick question.In practise to make up the octet which would give sodium the electronic configutration of Argon, there is ony space for 7.However the electronic confugration of sodium is [Ne]3s1The outer shell, 3, has the following orbitals.3s, three p orbtals 3px, 3py, 3pz AND five d orbitals , and 3dx2, 3dxy, 3dyz, 3dzx, 3dx2-y2 (sorry the sufixes don't come out right- you need to look at a text book)Theoretically then we have space for 18 electrons in the outershell, so sodium could take on 17!
sodium chloride dissolve in water because of vacuous compound
potassium- element 19, alkali metals, atomic symbol "K" potassium is rarely if ever found in its pure form, this is because it only has one valence electron, the closer an atom is to a totally full or totally empty valence energy level, the more it wants to bond with an element that will give it a full shell, so in the case of covalent bonds, potassium will bond with an atom that has 7 valence electrons or just something that will give the compound 8 valence electrons hope this helped!
no
The empty vial is weighed after pouring the sodium chloride out in order to determine the actual amount of product that was produced by the reaction. By taking the full vial and subtracting the empty vial you can calculate the weight of the product.
An electron is transferred from the 2s orbital of lithium to form a Li ion. This results in the formation of a Li+ ion with a filled 1s and empty 2s orbital.
The 'valency' of a cation describes the free orbitals it has to accept lewis electrons. For example, potassium is monovalent (or univalent), and only has one empty orbital to accept electrons, whereas calcium is divalent, and has two empty orbitals, (and a 2+ charge) to accept donor electrons for lewis bonding.
The empty space in a container is the volume inside the container that is not filled with any material. It is important to consider this empty space when determining the appropriate amount of material that can be safely and efficiently stored in the container.
An empty bottle is typically lightweight, has no liquid inside, and makes a hollow sound when tapped. It may also have a lingering odor of whatever liquid was previously stored in it.
Yes, you must urinate. Urine is continuously produced in your kidneys and stored in your bladder, and you must empty your bladder from time to time.
This is true, after you empty the recycle bin the contents that were in the bin are lost for forever. You can still restore something from the bin before hitting empty to save it.
the drum may be washed by dilute hydrochloric acid or you may use vinegar and finally with water.
You should only do that if your hamster stored something inappropriate in its pouches. You can gently push their cheeks and the contents will start falling out.
Fluid waste products, or urine, are stored in the bladder. This muscular organ can hold up to 18 ounces (or half a litre) of urine (in most healthy adults)m before we feel the urge to empty it.
Fill with water, maintain 2-3 days, stir, empty the tank; wash again with hot water.
