testtttt Flashcards
filteration
used to separate an insoluble solid from a liquid you use a filter funnel and a filter paper and the water leaves through the paper and the solid is left
crystallisation
used to separate a soluble solid from a liquid. you make the solid evaporate
distillation
used to separate water from a solid and keep the water. you heat the solution which turns into a gas and the rises up through the gas tube and then the gas goes through the cold condenser and then when it passes through the condenser it condenses and turns into a liquid and pours out so at the end were left with the crystals of the solid in the beaker and the liquid.
condensing
gases to liquid
chromatography
you draw a horizontal line in pencil because the pencil wont dissolve in the solvent and then you put dots of the colours you want to test then you have the solvent move up the paper and carrying the colours if the colours separate the compound is a mixture and if it has not separated the compound is pure
element
an element is something made up of 1 type of atom
compound
a compound is something with 2 or more elements chemically joined together
mixture
a mixture is something made up of 2 or more different substances not chemically joined together
what is the bonding that happens between non metals
convent bonding Ayaan chunky and fat no cap
what is the bonding that happens between non metals and metals
ionic bonding .how are you here u should skip this its way to ez ykyk
what was new lands law of octaves
the law of octaves was when you arranged the elements in increasing atomic weight it was rejected because it didn’t work with elements past calcium
how many elements are there
around 100
why was Mendeleev’s table accepted
it was accepted because he did 2 things no other scientist had done before this was leaving spots for undiscovered elements and he would switch the place for some elements to fit the patterns of the groups.
what is the function of white blood cells and what dose it do
white bloods cell catch micro organisms which helps prevent disease
what is the function of leaf cells and what dose it do
leaf cells absorb light this is used for photosynthesis
what is the function of cells in the intestine and what dose it do
cells in the intestine produce enzymes this is used to digest food.
what is the function of red blood cells and what dose it do
red blood cells transport oxygen and this is used for respiration.
what dose the nucleus do
it controls the cell
what dose chloroplast do
the chloroplast absorbs light energy and allows photosynthesis to take place
what dose the cell membrane do
the cell membrane controls functions in and out of the cell
the function of a cell wall
the function of a cell wall is to support the cell
function mitochondria
the function is Where most respiration reactions happen
function of the vacuole
to contain the cell sap to keep the cell firm
cytoplasm function
the function is that it is the place where chemical reactions to take place.
were are eggs produced
in the ovaries
where is sperm produced
sperm is produced in the testicles
what are the species in the food chain called
producer primary consumer secondary consumer tertiary consumer tertiary consumer
what breaks down the following: lipids starch and proteins
answers: lipase amylase and protease
function of the liver and pancreas
the liver produces bile and the pancreas produces enzymes
what is the thing that allows gas to enter called
the trachea
what dose the trachea spilt into
2 bronchi
what dose the bronchi split into
bronchioles
what do the bronchioles end with
air sacs called alveoli
where do gasses diffuse in and out of the bloodstream
in the alveoli
name 2 ways alveoli are adapted for gas exchange
they have a large surface area they have very thin walls
hoe dose aerobic respiration happen
it happens when glucose and oxygen react to create carbon dioxide and water and also energy
how dose anaerobic respiration happen
anaerobic reoperation happens when there is not enough oxygen for aerobic respiration and its word equation is glucose=lactic acid
anaerobic respiration in yeast word equation
it is glucose = ethanol + carbon dioxide
anaerobic respiration chemical equation or symbol equation
C6H12O6 -> 2C3H6O3
aerobic respiration chemical or symbol equation
C6H12O6 + 6O2 → 6CO2 + 6H2O
symbol equation for photosynthesis
6 CO2 + 6 H2O + light –> C6H12O6 + 6 O2
what do plants use as there source of energy
light
word equation for photosynthesis
carbon dioxide + water + light = glucose + oxygen
if a man is moving a box with a force of 21N and the box has a resentence of 22N will the box move foward
no no no
what is a series circuit
a series circuit is something which is a circuit but with no branches
what are the tree ways energy can be transferred
conduction convection radiation
