Consider the following reaction at equilibrium: NO2(g) + CO(g) = NO(g) + CO2(g) Suppose the volume of the system is decreased at constant temperature, what change will this cause in the system? A shift to produce more NO A shift to produce more CO A shift to produce more NO2 No shift will occur
Answers
Answer: Option (d) is the correct answer.
Explanation:
According to Le Chaltelier's principle, when there occurs any change in an equilibrium reaction then the equilibrium will shift in a direction that will oppose the change.
This means that when pressure is applied on reactant side with more number of moles then the equilibrium will shift on product side that has less number of moles.
For example,
Since here, there are same number of moles on both reactant and product side. So, when volume is decreased at a constant temperature in this system then there will occur no change in the equilibrium state.
Thus, we can conclude that in the given when volume of the system is decreased at constant temperature, then no shift will occur.

Explanation:
Hydrogen + Oxygen --> Water
(1) Write the balanced chemical equation describing this reaction using the lowest whole number coefficients.
2H2(g) + O2(g) ---> 2H2O(g)
(2) Identify the oxidizing agent and reducing agent.
Oxidizing agent = O (There is decrease in oxidation number from 0 to -2)
Reducing agent = H (There is increase in oxidation number form 0 to +1)
(3) Determine the number of electrons transferred in the balanced chemical equation
2H2(g) --> 4H+ + 4e- (4 hydrogen atom lost a single electron each)
O2 + 4e- --> 2O2- (Two oxygen gain 2 electrons each)
Total number of electrons transferred in the balanced chemical equation is 4.

The Ksp of FeCO₃ is 3.45x10-11 and the Ksp of CdCO₃ is 8.7x10-12.
What is Ksp?
Ksp is a mathematical expression used to predict the behavior of a saturated solution. It is an abbreviation of the term “solubility product constant”, and is derived from the thermodynamic equilibrium equation that exists between a solid and its dissolved ions in a solution. Ksp is used to predict the solubility of a given ionic compound, and is a measure of the maximum amount of solute that can be dissolved in a given solvent at a given temperature and pressure.
To initiate precipitation, the concentration of CO²⁻₃ must be greater than or equal to the solubility product of the least soluble salt, which is CdCO₃.
Therefore, the concentration of CO²⁻₃ must be greater than or equal to 8.7x10-12 M.

The statement, that describes the ‘control’in an experiment is "the name for the set of independent and dependent variables that will be controlled by the scientist."
What is a control in experiment?
A control is an element in an experiment that remains intact or unaffected by other variables. An experiment or observation aiming to minimise the influence of variables other than the independent variable is referred to as a scientific control. It serves as a standard or point of reference against which other test findings are measured.
In a scientific experiment, an independent variable is the variable that is modified or manipulated in order to assess the effects on the dependent variable. In a scientific experiment, the dependent variable is the variable that is being tested and measured. The designation given to the set of independent and dependent variables that the scientist will regulate.
Hence the correct option is D.

How many grams in one mole of B2?
__g
Answers
Final answer:
The number of grams in one mole of B2 can be calculated using the atomic mass of element B. This is found on the periodic table and then doubled for B2 since it's diatomic. If B is Oxygen for instance, 1 mole of B2 (O2) weighs 32 grams.
Explanation:
To find the number of grams in one mole of B2, we need to know the atomic mass of element B, which isn't provided in your question. However, you can find this information on the periodic table. Once you have the atomic mass of B, you can calculate the molar mass of B2 (which is two times the atomic mass of B) since 1 mole of a substance corresponds to its molar mass in grams.
For example, if element B is Oxygen (O), its atomic mass is approximately 16 g/mol. Therefore, the molar mass of B2 (O2 in this case) would be 32 g/mol. Hence, 1 mole of B2 (or O2) would weigh 32 grams.
