Answer:
The answer to your question is density = 635.3 g/ml (check the units)
Explanation:
Data
density = ?
volume = 85 ml
mass = 54 kg
Density is a physical property that relates the mass of an object and its volume.
The unit of this property are g/ml or kg/m³
In this problem, I will calculate the density in g/ml
Formula
density = mass/ volume
-Substitution
density = 54000 / 85
-Simplification
density = 635.3 g/ml
Answer:
The biodegradability of soap moleculea means the soap molecules are degradable in nature it doesn't causes water pollution as comparing as detergent.....
Answer:
The given element is Radon because its atomic weight is 222 amu.
Explanation:
Given data:
Percentage of A-219 = 13.92%
Percentage of B-222 = 72.16%
Percentage of C-225 = 13.92%
Atomic weight of element = ?
Solution:
Average atomic mass = (abundance of A isotope × its atomic mass) +(abundance of B isotope × its atomic mass) + (abundance of C isotope × its atomic mass) / 100
Average atomic mass = (13.92×219)+(72.16×222) + (13.92×225)/100
Average atomic mass = 3048.48 + 16019.52 +3132/ 100
Average atomic mass = 22200 / 100
Average atomic mass = 222 amu.
The given element is Radon because its atomic weight is 222 amu.
Answer: increase number of collisions
Explanation:
Decreasing the volume increases the likelihood of particles interacting more often.
Answer : Option C) The polar bonds are oriented in opposite direction.
Explanation : A molecule of carbon dioxide 
contains two polar covalent bonds. This molecule is non-polar because the polar bonds are oriented in the opposite direction.
In order to be a polar molecule, carbon dioxide must have both a slightly negative side and a slightly positive side in its molecule. The orientation of the lone pairs of electrons present on each oxygen atom cancels each other, making the molecule non polar.
