When connectors are marked with a combination of metals,
it can be used as a connector of one of the metals or an alloy of the two
metals. So in this case, since the marking is “Al – Cu” where Al is aluminium and
Cu is copper, therefore the answer is:
<span>Yes, it is suitable for use with copper, copper-clad
aluminum, and aluminum conductors.</span>
Answer: Beryllium phosphide
Explanation:it has a molecular weigt of 88.98407 g/mol
its CID is 16453515
Answer:
It is not dependent on the salt solute at all but the solute does have an affect.
Explanation:
in the equation you maybe aware of the I factor which represents the ions present in the solution. a non ionic will always have a I value of 1 a ionic can be 2 like in NaCl. What this means that all non ionic will lower the temperature depression but ionics will have a greater affect because for example salt breaks into Na and Cl will essentially hae more impurities than glucose which doesnt dissociate and will have a I value of 1
Answer:
Ideal Gas Law ( PV = nRT)
Explanation:
Using the Ideal Gas Law, we have; PV = nRT
Where P= Pressure = ?
V= Volume = 8.0 L
n = moles = 8.0
R = Gas constant = 0.0821 L.atm/mol/K
T = 80° c + 273 = 353.15K
Therefore Pressure would be; P = nRT/ V = 8 x 0.0821 x 353.15 / 8 = 28.9atm
Answer:
Explanation:
D. 2 Fe's, 3 O's
An atom is the smallest indivisible particle of a substance. Most notations of elements in actual sense depicts the combining atoms.
In Fe₂O₃, the subscript gives the idea of the number of combining atoms and their combining ratios. Here, weh have 2 atoms of Fe and 3 atoms of Oxygen.
Activated carbon filters use chemical means to seperate impurities from air:
Chemical reactions occurs when compounds are formed. Activated carbon filters are made up of activated carbons in which impurities have been removed and the pores of the carbon structure have become widened. This leaves the carbon with much surface area for chemical reaction to occur between impurities and the carbon in form of chemical adsorption. One important thing to note is that, in chemical change, it is difficult to resolve the reactants after the product is formed. In physical change, simple seperation techniques are used to seperate the reactants out.
