Answer:
decomposition
Explanation:
the reactants turn into two different products, thus the reaction is decomposition.
AB -> A + B
Answer:
Due to deficiency of Oxygen in atmosphere.
Explanation:
Oxidation is defined in two ways, 1) The addition of Oxygen and Removal of Hydrogen 2) The removal of electrons.
We will discuss the first definition for this question. The addition of oxygen to various compounds results in the oxidation of that compound.
Example: Oxidation of Methane;
CH₄ + 2 O₂ → CO₂ + 2 H₂O
In this example oxygen is added to methane and hydrogen is being removed from methane.
Oxidation type chemical weathering common more than 2 billion years ago because of less amount of Oxygen in atmosphere and the oxygen which was produced by plants reacted with different metals like Iron forming precipitates which precipitated to the bottom of oceans.
Answer:
OUTCOME VARIABLE: Attraction to negatively charged balloon
Explanation:
In an experiment, two major variables must be included viz: the independent variable and the dependent variable. The independent variable also referred to as the test variable is the variable that is being changed in the experiment while the dependent or outcome variable is the variable that responds to the changes made to the independent variable. The outcome variable is the variable that is measured in an experiment.
In this experiment involving Marianne wanting to know which objects will be attracted to a negatively charged balloon. The type of objects are the independent variable while the ATTRACTION is the outcome or dependent variable as it is dependent on the type of object used.
Answer: The volume of product formed is 0.26 L
Explanation:
As 
is the the excess reagent, 
is the limiting reagent as it limits the formation of product.
According to stoichiometry :
2 moles of give = 2 moles of 
Thus 0.01 moles of will give =
of
According to ideal gas equation:
P = pressure of gas = 101.325 kPa = 1 atm
V = Volume of gas = ?
n = number of moles = 0.01
R = gas constant =
T =temperature =
Thus the volume of product formed is 0.26 L
Answer:
I dont know at all and that is confusing.
