The laboratory apparatus that can keep 100 grams of a compound from absorbing atmospheric moisture is a desiccator. A desiccator is a glass container or apparatus that is used mainly for drying and preventing moisture from the specimen.
These elements are called ions. Elements choose to lose or gain electrons because they want to achieve electronic stability. All metals lose electrons and all non-metals gain electrons to get the respective stable electronic structure they want. As for metalloids, some elements in there gain while some lose electrons. When elements lose or gain electrons, they will form a charge, since the number of protons and neutrons are not balanced now. All non-metals form negative charged ions while all metals form positive charged ions. Compounds are formed when a positively charged ion is attracted to an negatively charged ion by the electrostatic force of attraction. For example, sodium chloride is a compound of sodium ion and chlorine ion. The positively charged sodium ion is attracted to the negatively charged chloride ion to form the compount.
First, you need to determine the elements in the equation. They are copper and fluorine, respectively. Next, we determine if the compound is ionic or covalent. Remember that a basic ionic cmpd is a metal bonded to a nonmetal, and a basic covalent compount is non-metal-non-metal. Copper is a metal, so the bond is ionic. To name an ionic compound, you have the first part (the metal) written regularly, and the second part (in this case a monoatomic non-metal) is written regularly, but the last part is dropped and replaced with "ide". So far, the name of our compound is Copper fluoride. There is a certain type of metal called a transition metal. These metals, unlike the alkali or alkaline earth metals, have no set charge. Therefore, we must determine copper's charge and indicate it in the name. Balancing the charges: fluoride has a -1 charge. There are two F ions, making the charge of the non-metals -2. The charge must be balanced to 0, which can be done using thie following equation: x + -2 = 0 --> add 2 to both sides, the twos cancel on the right, and we get x = 2. Therefore the charge of the copper ion is 2+. To indicate this in the name, you put the charge in roman numeral form in parenthesis after the metal. The final name is Copper (II) fluoride.
water
element
Carbon is an element.
Poly vinnil --- compount. or polyester
the removal of hydrogen (H) atoms from water molecules
Boron is an element. The lightest member of group 13 with 3 valence electrons
Remember that a compound is the combination of two or more elements. Cd is the symbol for an element (not a compount) named Cadmium.
"Malahide" is an Irish town located near Dublin. Maybe you mean the preservative, "Formaldehyde" which is an organic compount: CH2O, which is made from carbon, hydrogen, and oxygen
its really called a healing chamber;it has special chemical compount specificly formulated to speed the recovery process.its kinda neat
Copper (II) acetate has the chemical formula Cu(CH3COO)2.It is the primary component of verdigris, the green patina seen on copper statues.
Compound interest is the interest calculated on the initial principal and also on the accumulated interest from previous periods. This means that interest is earned on both the original amount deposited and the interest that has been added to it. Over time, this can lead to exponential growth of the investment or loan, as the interest compounds at regular intervals. It contrasts with simple interest, where interest is only calculated on the principal amount.
Heatsink compount or special heat pad. The reason for this is to form a tight thermal bond between the processor (CPU = Central Processing Unit) and heatsink for the best transfer of heat away from the CPU.
