How science works
Answer
RAG
What is the actual answer?
What is a control variable?
What is an independent variable?
What is a dependent variable?
What is a dependent variable?
Use what you have learned last lesson in order to name each of the compounds below:
Formula
Number of each element
CH4
C = 1
H = 4
H2O
H =
O =
Al2O3
Al =
O =
NaOH
Na =
O =
H =
H2SO4
H =
S =
O =
2CO2
C =
O =
3C6H14
C =
H =
State how many of each element are present below:
1.
The small numbers only affect the element directly in front
H2O = 2 hydrogens, 1 oxygen
2.
The big number in front of a compound affects everything in that compound
2H2O = 4 hydrogens, 2 oxygen
3.
To balance an equation, you can only change the big numbers, not the small numbers after individual elements
4.
When you change a big number, you have to take into account all of the atoms that it changes
5.
The number of atoms on each side of the equation should be the same
