Metals such as aluminum can be formed into thin sheets because they are Malleable

Explanation:

A malleability is the property of a material that describes its ability to be deformed under pressure or compressive stress such that it can be moved about spread out without breaking (analogy dough in bread making). As such a malleable metal can be made into flat thin sheets by applying compressive stress such as hammering.

In the process, malleable metals such as gold can be flattened into a metal leaf, such as gold leaf

Malleability is primarily present in metals as nonmetals are likely to be brken when subjected to compressive stresses

Aluminium, gold and silver are highly malleable, while zinc is malleable between the temperatures of 100 °C and 200 °C.

the answer is false

explanation:

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
