Answer:
Float
Explanation:
If the weight of liquid displaced and the weight of an object are the same, the object will float in the liquid.
From Archimedes principle, when an object is immersed in fluid, a force called upthrust supports it and it equal to the weight of the liquid displaced.
When in a liquid, the weight of the liquid displaced is the same as that of the of the object, it will float and not sink.
Answer:
8 mol of hydrogen will react with 1 mol of sulfur.
Explanation:
We'll begin by writing the balanced equation for the reaction.
This is given below:
8H2 + S8 —> 8H2S
Now, let us carefully observe the mole ratio of the reactants.
This is illustrated:
The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1
From the balanced equation above,
We can thus, concluded that:
8 moles of H2 will reacted with 1 mole of S8.
The principal thing that one can read from a periodic table is the atomic number which is the number in the box that the element symbol appears and it means the number of protons in the nucleus of its atom and this number determines its chemical properties and is unique for each chemical element. The table is color coded to show the different types of elements ie "transition metals, alkali metals, noble gases" etc. and these different types are grouped together.
