Grade 10 Academic Science Chemistry

Chemistry Test Flashcards

Where does the 7 + 1 rule start and end

Starts at Nitrogen ends at iodine + hydrogen

Name all 5 prefixs, and include which prefix is never used for the first element

mono, di, tri, tetra, penta (mono is never used)

Name both sides of the arrow

reactants - products

Metals are on which side of the periodic table

left side

Non metals are on which side of the periodic table

right side

Descriptors of metals

Metals

• Shiny (lustrous)

• Malleable (can be hammered into sheets)

• able to be stretched into wires)

• Good conductors of heat & electricity

• Usually solid

Description of non mentals

• Dull (not shiny)

• Brittle (breaks/crumbles if stretched or hammered)

• Poor conductors (insulators)

• Can be solid, liquid, or gas at room temp

Name all 4 types of chemical reactions

Synthesis

Decomposition

Single

Double

Define all 4 types of chemical reactions

Synthesis = A+B=AB

Decomposition= AB = A + B

Single = A + BX = AX + B

Double = AX + BY = AY + BX

Combustion → Hydrocarbon + O₂ → CO₂ + H₂O (if complete)

skeleton equation is the same as

unbalanced equation

what does pH stand for?

powers of hydrogen

what is the purpose of pH

measures the strength of an acid or base

at what number does a chemicals pH’s levels have to be for it to be neutral

7

For a chemical to be neutral it needs to have a equal number  of two elements, what are they

hydroxide (OH) and hydrogen ions

Ph more than seven =

base, stronger, larger

Ph less than seven =

acidic/very acidic

Acid indicator

sour, turns blue, reacts with chalk/calcium carbonate, produces CO2, reacts with zinc & other metals to produce hydrogen gas

Base

Bitter, slippery, changes the color of red litmus, corrosive conducts electricity

Neutralization reactions are =

double displacement

Neutralization equations produce

water + salt

Neutralization equations have a ____ and ____ as reactants

base and acid

In a bohr rutherford diagram the atomic number is the same as

protons/electrons

Atomic mass - atomic number = ?

Neutrons
