Summary Of Matter And Will Use Lab Equipment To Separate A Mixture

Introduction The purpose of this Lab was to identify the density of the unidentified object and determine what substance the unidentified object given by the teacher was. The density calculated in the experiment will stay the same because the density of the unidentified object will stay constant. The Independent Variable of this experiment was the calculated density and the unidentified object given. The Dependant Variable for this experiment was the density.

Hana Phan Mrs Thomas Honors Chemistry P. 2 9-20-17 Chapter 2 Booknotes 2.1 What is matter? matter - anything that has mass or volume volume - the amount of space an object occupies mass - a measure of how difficult it is to change the object’s state of motion atoms - the basic unit of matter molecules - a neutral group of atoms held together by chemical bonds physical properties - properties that can be observed or measured without changing the composition of matter state - the condition of being a gas, liquid, solid, plasma, or neutron star chemical properties - properties that can be observed only when substances interact with one another Matter is anything that has mass or volume. Volume is the amount of space an object occupies while

You can create an inventory policy for the office by scheduling inventory to be taken monthly, or weekly, whichever schedule fits your offices ordering needs. You could distribute the task among employees by doing it in pairs or assign a list of supplies that each person is responsible for keeping inventory of. A very vital tool for completing an inventory check is having a list of the supplies and equipment that you need to take inventory of. You can use Excel to create the inventory list. I would recommend that this list have at least two columns.

An Independent Variable would be health conditions. For example, if one has asthma or not, this will affect the number of breaths that one makes. Thus, those health conditions cause the number of breaths to change. A Dependent Variable would the size of the bag. The Controlled Variables would be time intervals, number of people in a group, etc.

The location I chose for my inventory lab rotation is the Warm Springs Rehab Hospital in Kyle, TX. Warm springs rehab is a Hospital where patients are getting treated will and will be taken good care of and its also a place to feel comfortable such as a home. Which I spent two hours there. At the beginning, we were introduced to the Caroline Holt which is the dietitian of the Warm Springs Hospital, Caroline showed me and my partner the kitchen and she explained what they do on a daily bases, we also saw the dishwasher area which was very neat, then she showed us the cooking area which was next to the cooler, which is easier for them when they need to cook, which everything was organized and clean. After that we went to the office which was

Use the evidence provided by the tests to identify the mystery powder. The mystery powder (#5) is the baking powder. My partners and I figured this out because the physical and chemical properties of both of the substances are very similar. For example, both powders are not soluble in water, and they both turned red when they reacted with the universal indicator.

8) Explain how each experiment type (question 7) differs from the

Explain?” The mixture is a homogeneous mixture because you can’t see all the parts of the substances

The idea of substance is capable of producing simple ideas in us, it is like the material substance which is essentially solid of which all material things are made of. 2. What are the degrees of our knowledge? Explain them. Intuitive knowledge: the ability for the mind to perceive the agreement or disagreement of two ideas immediately by themselves without proving or examining any other idea.

The objective of the sludge lab was to determine how many different pure substances were in the sludge by using the methods and techniques we have learned throughout the year. We had to pick separation methods so we could separate our sludge and then test characteristic properties on our separated liquids and solids. This experiment made us use our knowledge on characteristic properties to pick the ones we should test to help us identify our pure substances. Characteristic properties are properties that help identify a solid or liquid. Each solid or liquid has a certain density, boiling point, solubility, flammability, so if you know what each one is then you can use that information to help you identify your solid or liquid.

If a person asked what has four paws, claws, fur, and whiskers, someone would identify it as a cat because those are essential properties that make it a cat. It is the concrete individual thing which remains constant despite the fact that it changes and has different properties at different times (142). A tree's leaves might fall off during autumn,

The way it is organized is their structure. For example, a kid can use similar blocks to build up a wall and then break down the blocks and build up a home. The material or matter for every situation would be the similar which are the blocks. however, the wall and the house have the matter arranged in various ways. They have various structures.

Properties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has

You are given a known solid substance with its melting point which has high solubility in hot water and low solubility in cold water. You are assigned the following task: i. Determine if the substance is pure ii. If impure, find a suitable method for its purification by using the given information about the substance How would you proceed, clearly explain your rationale? i. To find if it is a pure substance we see if there is a change in melting point. ii.

All matter is made of particles, which can act a certain way depending on the differences in forms (liquid, solid, gas) and transitions, which can be observed with different properties as well as different appearances (size, color, etc). In the activity “How Small?” , we smashed a sugar cube to get smaller pieces of sugar. We also identified different types of sugar using properties. This evidence means that the sugar can have multiple sizes and different properties but can still be the same thing.
