After the big bang, atoms in gas clouds experienced a greater gravitational pull to each other than atoms in other regions of the universe. which two statements are scientific facts that explain this phenomenon? gravitational pull on an object decreases with a decrease in its temperature. as the density of an object increases, it becomes immune to gravitational force. gravitation between two objects increases when the distance between them decreases. gravity doesn’t exist between objects that are less than one light-year apart. when the mass of an object increases, its gravitational pull also increases.

When the mass of an object increases, its gravitational pull also increases.

The big bang describes the formation of the universe from an initial explosion according to physicists.

We know that the gravitational force between objects is directly proportional to the product of the masses of the objects and inversely proportional to their distances apart.

Hence, the two statements which are scientific facts that explain this phenomenon described are;

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
