Pseudoscience refers to belief, theories and practices that claims to be scientific but which have no basis in scientific facts.
Pseudoscience has many traits two of which are:
1. It is based on dogma and uncritical belief. Counter evidence might draw hostility from pseudo scientists.
2. There is usually suppression or distortion of data. Pseudo scientists typically perform selective data gathering, in which they only gather and consider favorable data that support their claims. <span />
The physical quantity that is not used when determining the stoichiometry in this experiment is temperature.
Stoichiometry offers a way in which we can calculate the amount of reactants and products using mass - mole relationship. The mass of reactants, number of moles of reactant, mass of product and mass of precipitate can all be used to determine the stoichiometry.
However, the temperature of a reaction is not used to determine the stoichiometry of the reaction.

Which physical quantity is NOT used when determining the stoichiometry in this experiment?
- mass of precipitate
- mass of product
- moles of reactant
- temperature
Answer:
x = 2+
Explanation:
1) FADH2 + Q => FAD + QH2
Since H is added to Q
=> Reactant reduced is Q
(2) Balancing charges on both sides of the equation gives:
QH2 + 2 cyt c(Fe3+) => Q + 2 cyt c(Fe2+) + 2 H+
Thus x = 2+
The answer is A. the solar ultraviolet ray breaks the molecule apart
Answer:
The products will occupy a volume of 56.448 L when measured at STP
Explanation:
The first thing to check here is the mole ratio of the reactant in question to the product.
From the chemical equation, we can see that 1 mole of CS2 gave a total mole of 3 moles of the products(1 mole of carbon iv oxide and 2 moles of sulphur iv oxide)
Now if 1 mole of reactant can give 3 moles of the products,
then 0.84 mole of reactant will give 3 * 0.84 moles of the product = 2.52 moles of the products
We are told to calculate the total volume.
At STP , 1 mole of a gaseous substance will occupy a volume of 22.4L or 22.4 dm^3 (liters and dm^3 are same)
This means that 2.52 moles will occupy a volume of 22.4 * 2.52 = 56.448L
