Q

What type of bond is formed by the transfer of electrons?

A

Q

What are the rules for naming ionic compounds with metals that have a fixed charge?

A

Name the metal and add ‘ide’ to the non-metal

Example: Magnesium Chloride (MgCl2).

Q

How will the ticker tape look when the object is showing uniform motion

A

Equally spaced

25
How will the tinker tape show when an object is speeding up
More spread out
26
How will the Tucker tape look when an object is slowing down
Closer together
27
How is force related to uniform and non uniform motion
Uniform motion - no net force Non uniform- net force required to produce acceleration in balanced forces
28
Net force
F=ma

What makes something an acid? How do we name it?
Acids are substances that can donate or accept electron pairs
32
What are the five types of chemical reactions
Single displacement Double displacement Synthesis Decomposition Combustion
33
Example of synthesis reaction
2h2+O2=2H2O
34
Decomposition example
2H2O2=2H2O+O2
35
Decomposition example
2H2O2=2H2O+O2
36
Single displacement example
Zn+2HCI= ZnCl2+H2
37
Single displacement example
Zn+2HCI= ZnCl2+H2
38
Double displacement
NaCl+AgNO=NANO3+AgCl
39
Combustion example
CH4+2O2=CO2+2H2O
40
What makes something an acid
Produces hydrogen ions in solution
41
What makes something a base
Substance that produces hydroxide ions in solution
42
How is water related?
Water accepts hydrogen ions when mixed with acid When waters mixed with a base the base donated hydrogen atoms and acts like acid
43
What can we use to show how acidic basic something is?
The ph scale Ex: lemons juice
44
What is one thing you can make at home?
Boiling red cabbage
45
What scale do we use to measure acidity? What is neutral? What is acidic? What is basic?
Ph scale Neutral= ph of 7 Acidic= ph up to 7 Basic= ph 7-14
46
What is an ecosystem?
Community of organisms and their physical environment interacting together Ex:forest, desert and grassland
47
What is the difference between a food chain and a food web?
Food chain shows who eats who Food web is all food chains in the ecosystem
48
What is a consumer
Organism that must eat other or consumers to survive Ex: lions,wolves,deer
49
Producers
Organism that uses photosynthesis or another form of synthesis to make food Ex:trees, grass
50
Detritus
Waste from plants and animals(includes remains Ex: fish scales, dead skin
51
Detritus
Organism that feeds on detritus in the process releasing nutrients to the soil and water Ex: beetles, earthworms
