HELP ASAP
1) which change is chemical?
• water undergoing electrolysis
•water freezing
•water evaporating
•water boiling
2)which number remains unchanged during photosynthesis
• The number of glucose molecules
• The number of carbon atoms
• The number of water molecules
• The number of carbon dioxide molecules
3) in a chemical reaction which aspect of the reactants change
•mass
•atoms
•nuclei
•total mass
4) a young snake eats and digest a mouse the increase in the snakes mass equals
•the mass of the mouse
• The Mas of the mouse plus the mass of waste produced by the snake
• The mass of the mouse plus the original mass of the snake
• The mass of the mouse minus the mass of waste produced by the snake
5) Cellular respiration transforms glucose and oxygen into carbon dioxide water and energy
C6H12O6 + 6O2 —> 6CO2 + ?H2O + energy
based on the law of conservation of matter, what is the missing coefficient for water?
•4
•8
•2
•6
Which change is chemical?
~water undergoing electrolysis: liquid water becoming oxygen and hydrogen molecules
Which number remains unchanged during photosynthesis?
~the number of carbon atoms
In a chemical reaction, which aspect of the reactants changes?
~mass
A young snake eats and digests a mouse. The increase in the snake’s mass equals
~the mass of the mouse minus the mass of waste produced by the snake.
Based on the law of conservation of matter, what is the missing coefficient for water?
~6

Which change is chemical?
ANSWER - water undergoing electrolysis: liquid water becoming oxygen and hydrogen molecules
Which number remains unchanged during photosynthesis?
ANSWER - the number of carbon atoms
In a chemical reaction, which aspect of the reactants changes?
ANSWER - arrangement of the atoms
A young snake eats and digests a mouse. The increase in the snake’s mass equals?
ANSWER - the mass of the mouse minus the mass of waste produced by the snake
Cellular respiration transforms glucose and oxygen into carbon dioxide, water, and energy.
C6H12O6 + 6O2 → 6CO2 + ?H2O + Energy
Based on the law of conservation of matter, what is the missing coefficient for water?
ANSWER - 6
Hopefully this helps you lovely people, take care now~
By the way, frozen water is H2O
Evaporated or evaporating water is H2O too.
