What is the colour of metal pair of zinc and iron?
The colour of a metal pair of zinc and iron can vary. Zinc is a shiny bluish-white metal, while iron is a silvery-grey metal. When zinc and iron are combined in an alloy, such as in galvanized steel, the resulting colour is typically a dull grey or silver color.
What is an anode in a hot water cylinder and what does it do?
It is the "sacrifice" part of a corrosion protection system: When two different metals are connected between them and are contacted by a electrolyte (water with dissolved ions), a small electric current is generated by them (thats how an electric battery is constructed) and one of the two metals corrodes (the anode or less noble of the metal pair) To protect an iron tank from corrosion you can connect to it a magnesium anode, in this metal pair the magnesium will corrode, thus protecting the iron from corrosion. If a copper pipe is soldered to the iron tank will produce the opposite effect, that is, as copper is more noble than iron, the anode will be the iron and it will corrode
Does iron have a lone pair of electron?
iron has unpaired electrons. the term 'lone pair' is not used for metals
Which element in each pair has atoms with a larger atomic radius strontium or magnesium?
Strontium
What is the colour of Justin Bieber last pair of shoes?
purple
How do you cut iron nails?
To cut iron nails, you can use a hacksaw or a pair of wire cutters. Simply place the nail in the tool's jaws or against the saw blade and apply pressure to cut through the iron. Be sure to wear appropriate safety gear, such as gloves and eye protection, when cutting metal.
How can a twisted pair cable be identified?
usually by the colour/pattern on the insulation
What colour makes brown?
Red and green or any other complementary pair.
Is the reaction of magnesium and hydrochloric acid acid-base reaction?
A Lewis base (magnesium) donates a pair of electrons. Magnesium goes from no charge to a 2+ charge in the reaction with hydrochloric acid.Mg(s) + 2HCl(aq) --> MgCl2(aq) + H2(gas)
What pair of reactants would produce hydrogen most slowly?
The pair of reactants that would produce hydrogen most slowly is one that has a high activation energy barrier to overcome in order for the reaction to proceed. For example, a reaction between a less reactive metal like copper and a weak acid like acetic acid would produce hydrogen slowly compared to a more reactive metal like magnesium and a strong acid like hydrochloric acid. This is because the less reactive metal and weak acid combination would have a slower reaction rate due to the higher activation energy required for the reaction to occur.
Which alkaline earth metal is the most likely to attract an electron pair?
The electronegativityÊ of alkaline earth metals decreases as you go down the group due to increase in atomic radius. The earth alkaline metals are beryllium, magnesium, strontium, barium and radium. Radium has the smallest electronegative.
How are traits inherited by an individual can be determined by one pair of genes?
alleles.
