Complete the following sentence: In a reaction containing two reactants, if one of the reactants is in excess, the other reactant is known as the ______ reactant.
Answers
Answer:
excess reactant
Explanation:
The excess reactant is the reactant in a chemical reaction with a greater amount than necessary to react completely with the limiting reactant. It is the reactant(s) that remain after a chemical reaction has reached equilibrium.
In a reaction containing two reactants, if one of the reactants is in excess, the other reactant is known as the limiting reactant which decides the yield of the reaction.
What is limiting reactant ?In a reaction, all the reactants have to be in correct stoichiometry to complete the reaction. To achieve the mole ratio of the reactants is very much important for the completion of a reaction.
If a reactant is insufficient in amount, then the reaction will stop as soon as this reactant is consumed. Hence, this reactant determine the yield of the product. This reactant which is not in correct stoichiometry for the complete reaction is called the limiting reactant.
The reactant which is excess in quantity thus does not have a role in the yield of the reaction is called the excess reactant. Whatever, the concentration of this reactant in extra, the reaction does not proceed after the consumption of limiting reactant.

A 2.5 L container holds a sample of hydrogen gas at 291 K and 180 kPa.
If the pressure increases to 350 kPa and the volume remains constant, what will the new temperature be?
Round your answer to one decimal place.
Answers
Answer:
The new temperature will be 565.83 K.
Explanation:
Gay Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant. This law says that the pressure of the gas is directly proportional to its temperature. This means that if the temperature increases, the pressure will increase; or if the temperature decreases, the pressure will decrease.
In other words, Gay-Lussac's law states that when a gas undergoes a constant volume transformation, the ratio of the pressure exerted by the gas temperature remains constant:
[tex]\frac{P}{T} =k[/tex]
When an ideal gas goes from a state 1 to a state 2, it is true:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case:
P1= 180 kPaT1= 291 KP2= 350 kPaT2= ?Replacing:
[tex]\frac{180 kPa}{291 K} =\frac{350 kPa}{T2}[/tex]
Solving:
[tex]T2=350 kPa*\frac{291 K}{180 kPa}[/tex]
T2= 565.83 K
The new temperature will be 565.83 K.

what’s the correct answer !!
Answers
Answer:
From my side the correct option is "A"
Explanation: Reasons for its correction are ,
1) Highly reactive: Nanoparticles are therefore extremely unstable and easily change themselves or react with active substances to reach a relatively stable state in some cases. This causes desired changes or undesired changes to nanoparticles and thus makes them exhibit a high reactivity and a poor stability.
2)Small size: Nanotechnology can provide rapid and sensitive detection of cancer-related molecules, enabling scientists to detect molecular changes even when they occur only in a small percentage of cells. Nanotechnology also has the potential to generate entirely novel and highly effective therapeutic agents.
You need to make an aqueous solution of 0.150 M sodium fluoride for an experiment in lab, using a 500 mL volumetric flask. How much solid sodium fluoride should you add?
Answers
Answer:
Explanation:
Solution required is .15 M 500 mL sodium fluoride .
molecular weight of sodium fluoride = 42
one mole of sodium fluoride = 42 grams
No of moles contained in the solution of .15M , 500 mL solution
= .15 x 0.5 moles = .075 moles
1 mole = 42 g
.075 moles = .075 x 42 = 3.15 grams .
So mass of sodium fluoride required = 3.15 g .

Predicting the future based solely on the position of the planets is an example of pseudoscience.
Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.
Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.
Any other statement or belief that is not based on these procedures is said to be pseudoscientific.
