______ metal is a part of hemoglobin a biomolecule.

  1. Aluminium

  2. Copper

  3. Iron

  4. Calcium
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Metals are available as micro-elements in our body. They are needed for conduction of nerve impulses, to carry oxygen by blood, to facilitate enzyme reactions and more. So, metals are used in medicine to cure any metal deficiency diseases in humans and animals. Ex. iron is a part of haemoglobin a biomolecule. Hence, it is used as ferrous sulphate to cure some forms of anaemia.

Multiple choice physics measurement and effects of heat heat exchange calorimeter measuring thermal quantities by the method of mixtures

Calorimeters are generally made of

  1. copper

  2. brass

  3. aluminium

  4. zinc
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Calorimeters is made of copper because:
1) Copper has low specific heat capacity and thus it reaches equilibrium temperature quickly by absorbing small amount of heat.

2) Cu is highly malleable and hence very thin box of small mass can be made, thus decreasing heat capacity of box.

3) Cu is good conductor of heat.
Multiple choice chemistry metals reaction of metals reactions of metals chemical properties of metals

The amphoteric metallic oxide is:

  1. calcium oxide

  2. barium oxide

  3. zinc oxide

  4. copper (II) oxide
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

 An amphoteric oxide is an oxide that can act as either an acid or base in a reaction.
$Al _2O _3$ is an amphoteric oxide. When reacted with HCl, it acts as a base to form the salt $AlCl _3$. When reacted with NaOH, it acts as an acid to form $NaAlO _2$.
also, zinc oxide is an amphoteric oxide.
