Answer : b. mixture
<h3>Further explanation</h3>
Element and compound are included in pure substance where the composition is the same in each part
Elements are made up of 1 type of atom, while the compounds of 2 or more types of atoms
, both can be represented in the form of chemical symbols
A mixture is a combination of substances. The properties of a substance in the mixture component are unchanged
The mixture can be a homogeneous mixture or a heterogeneous mixture
- the homogeneous mixture if each part has the same composition
- the heterogeneous mixture if each part has a different composition
Solution including into Homogeneous mixture, while suspension into a heterogeneous mixture
So a term that could refer to heterogeneous matter : b. mixture
Answer:
Molecules move freely around since they don't have a definite shape. This is the reason water stays liquid and couldn't be gripped.
Answer:
atoms bond to attain neutral configuration or to get noble gas configuration.
Explanation:
atoms always want to be stable by attaining noble gas configuration.
they do so by forming bonds. they also bond to each other to make their outer electrons stable that is if the atom has an excessive electron than its neutral configuration it can bond to another atom that has one less electron than its neutral configuration by ionic bond.
Home safety is always very important, but it becomes a particular concern when a child enters a home. This type of safety includes many different considerations--you want to protect family members from deadly falls, fatal fires, hazardous ingestions, and more. Practicing safety at home is also an important consideration if you have elderly people in your home. It's even important if you have pets in your home. You have to be diligent to keep all dangerous items in your home out of the reach of people or animals it can harm. To maximize home accident prevention, make sure all child-safety locks are secure, all smoke and carbon monoxide detectors have fresh batteries, and numbers for emergency services and personnel and prominently and clearly displayed.
Hvap, Tvap, Mr are constants
Hvap = 443.38 kJ/kg = 196417.34 J/mol
Tvap = -85.1 °C
Mr = 36.5 g/mol
n = 1.80 mol
ΔS = n*Hvap/Tvap
ΔS = 1.80 * 196417.34 / (273-85.1)
ΔS = 1881.59 J/K = 1.882 kJ/K
