What do you call in the matter that has two types which are heterogeneous and homogeneous?
When two or more substances are mixed together the result is called a mixture. Mixtures can be classified into two main categories: homogeneous and heterogeneous. A homogeneous mixture is one in which the composition of its constituents are uniformly mixed throughout.
What is form when two or more substances are combined?
Compounds. Explanation: Two or more elements combined into one substance through a chemical reaction such as water form a chemical compound. All compounds are substances but not all substances are compounds. … Chemical substances are often called ‘pure’ to set them apart from mixtures.
What are the substances making up a mixture called?
A pure substance consists of a single element or compound. Iron is formed only of iron (Fe) atoms table salt is formed only by sodium chloride (NaCl) molecules. A mixture however is made up of different compounds and/or elements.
Is milk a chemical?
Milk is a heterogeneous mixture which can be defined as a complex chemical substance in which fat is emulsified as globules major milk protein (casein) and some mineral matters in the colloidal state and lactose together with some minerals and soluble whey proteins in the form of true solution.
Which of the following is not a physical or chemical change?
(D) Combustion of Liquefied Petroleum Gas (LPG)
In the case of melting of ice only the physical state of water changes . Therefore these both are physical changes. When we dissolve salt in water salt simply fits into the voids/gaps between the water molecules and no chemical property is changed.
What kind of substance is oil?
Why is water called water?
What is water chemistry?
Water is a chemical compound consisting of two hydrogen atoms and one oxygen atom. The name water typically refers to the liquid state of the compound. The solid phase is known as ice and the gas phase is called steam. Under certain conditions water also forms a supercritical fluid.
Why is water liquid?
Which process depicts a chemical change?
Which among the following is a physical change?
Examples of physical properties include melting transition to a gas change of strength change of durability changes to crystal form textural change shape size color volume and density. An example of a physical change is the process of tempering steel to form a knife blade.
Which one of the following is a physical change?
Detailed Solution. Heating of platinum crucible is a physical change as in this process formation of new substance do not take place and the change is reversible. Physical change is the change from one phase of matter (solid liquid or gas) to another and the substance is not altered.
Why TiO2 is white?
Atomic number of titanium is 22 and its electronic configuration is . Electronic configuration of is . Since there are no unpaired electrons therefore molecule is white in color.
What does TiO2 stand for?
How do you get TiO2?
TiO2 is produced from either ilmenite rutile or titanium slag. Titanium pigment is extracted by using either sulphuric acid (sulphate process) or chlorine (chloride route). The sulphate process employs simpler technology than the chloride route and can use lower grade cheaper ores.
Is Mica water soluble?
Mica powder is an oil soluble colorant it is not water soluble. In general mica powders do not mix well in water-based products like room sprays shampoos or body washes. They are ideal however for soap making and cosmetic applications.
Can you eat titanium dioxide?
