In an endothermic reaction, the ______ have more energy than the _______.
A. reactants, products
B. surroundings, products
C. products, reactants
D. reactants, surroundings
Answer:
C
Explanation:
If the products have a higher energy level than the reactants then the reaction is endothermic.
In an endothermic reaction, the reaction mixture absorbs heat from the surroundings. Therefore, the products will have a higher energy than the reactants and ΔH will be positive.
In an exothermic reaction, the reaction mixture releases heat to the surroundings. Therefore, the products will have a lower energy than the reactants and ΔH will be negative.
How many moles of silver can be produced from silver nitrate from 1 mole of zinc?
Answer:
Answer: 6.5 moles of silver metal is formed in the given chemical reaction. The moles of excess reagent left are 0.55 moles.
Explanation:
To calculate the moles of silver formed and the moles of excess reagent left after the reaction, we need to balance the equation first and need to find the limiting and excess reagent.
The balanced chemical equation is:
Zn + 2AgNO3 ---> Zn (NO3)2 +2Ag
By Stoichiometry:
2 moles of Silver nitrate reacts with 1 mole of Zinc metal
So, 6.5 moles of silver nitrate will react with = 1/2 x 6.5 = 3.25 moles of zinc metal
The required amount of zinc metal is less than the given amount of zinc metal, hence, it is considered as an excess reagent.
Therefore, silver nitrate is the limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
2 moles of silver nitrate produces 2 moles of silver metal
So, 6.5 moles of silver nitrate will produce = 2/2 x 6.5 = 6.5moles of silver metal.
Number of moles of excess reagent left after the completion of reaction = (3.8 - 3.25)moles = 0.55 moles
Hence, 6.5 moles of silver metal is formed in the given chemical reaction. The moles of excess reagent left are 0.55 moles.

The unknown metal sulfates are hygroscopic and will absorb water from air. The unknowns must thus be kept in desiccators to remove any absorbed water. How would your results be affected if your unknown sample was not desiccated? Would this error cause your calculation of the mass percent of sulfate in the unknown to be too high or too low? Explain.
The sample will be heavier since it will include water if it wasn't desiccated. Therefore, it would be either too high or too low when we calculated the mass percent of sulfate.
What would happen to our results if the unknown sample wasn't dried out?The sample will be heavier since it will include water if it wasn't desiccated. Therefore, it would be either too high or too low when we calculated the mass percent of sulfate.
Water will increase the bulk of the compound when it is added. The compound as a whole will get heavier as a result. However, an element's or molecule's mass does not change.
Therefore, when the denominator rises while the numerator remains constant This implies that your share of the outcome will decline. Because the numerator remains constant while the denominator expands as a result of the water addition, your mass percent will be too low. Consequently, your mass percentage will be too low.

A 1M solution of barium nitrate is added to the solution. What is the solubility of barium hydroxide after this addition
The solubility of the barium hydroxide after the addition of a 1M solution of barium nitrate is 0.035M
Barium nitrate is a salt that dissolves entirely in solution and is soluble. This indicates that before the salt dissolves, there will be a one molar concentration of barium ions. We may anticipate that the equilibrium will be pushed to the left and the barium hydroxide will be less soluble because we have increased the product side of the reaction. The common ion effect is the name given to this shift in equilibrium.
To ascertain the salt's solubility, we shall use an ICE table.
I. There is a one molar concentration of barium ions (from the barium nitrate) in the solution before the salt starts to dissolve, but there are no hydroxide ions present.
C. The unknown increases in each ion can be referred to as 1+ and 2x, respectively, because every dissolved molecule of barium hydroxide will produce one barium ion and two hydroxide ions. Observe how the previously added one molar concentration in the solution will be combined with the increased barium ion concentration.
E. At this point, we set the solubility equation to the constant representing the solubility product.
[tex]Ba(OH)_{2}[/tex] ⇔ [tex]Ba^{2+} + 2OH^{-}[/tex]
Ksp is defined as:
Ksp = [tex][Ba^{2+}] + [OH^{-}]^{2}[/tex]
5 x [tex]10^{-3}[/tex] = [tex][Ba^{2+}] [OH^{-}]^{2}[/tex]
It added a solution of 1M of [tex]Ba^{2+}[/tex]
5 x [tex]10^{-3}[/tex] = [tex][1M][/tex] [tex][OH^{-}]^{2}[/tex]
The addition of barium hydroxide [tex]Ba(OH)_{2}[/tex] gives:
[tex][Ba^{2+}] = 1M + x[/tex]
[tex][OH^{-}]^{2}[/tex] [tex]= 2x[/tex]
Replacing:
5x[tex]10^{-3}[/tex] = [tex][1+x][/tex] [tex][2x]^{2}[/tex]
[tex]10^{-3} = 4x^{2} + 4x^{3}[/tex]
[tex]x = 0.035 M[/tex]
Your question is incomplete, but most probably your full question was to consider the following balanced equation for the dissociation of barium hydroxide in an aqueous solution.
[tex]Ba(OH)_{2} (s) = Ba^{2+} (aq) + 2OH (aq)\\Ksp = 5* 10^{-3}[/tex]

Bromine is less reactive than fluorine because it is … for fluorine to gain an electron
No, Atoms of different element can not have same atomic number because only same type of atoms combine to form element. Atoms belonging to different element can have different atomic number. Therefore, bromine is less reactive than fluorine because it is easier for fluorine to gain an electron.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same. Two or more than two atoms with different physical or chemical properties can not combine together to form an element.
Down the group, electronegativity decreases. Electronegativity is the ability of an element to gain the shared pair of electrons. Fluorine is more electronegative than chlorine. Reactivity of halogens is directly proportional to electronegativity of the halogens.
Therefore, bromine is less reactive than fluorine because it is easier for fluorine to gain an electron.

What is the legal limit?
The lowest concentration that can officially be reported for any constituent in drinking water is known as the "Legal Limit".
Contamination of water:
The level that safeguards human health and that water systems can attain with the finest technology is reflected in the regulatory limit for a contaminant.
How does it occur:
Plumbing components are the main way that lead and copper enters the drinking water. The health effects of lead and copper exposure can range from brain damage to stomach discomfort.Nitrogen, bleach, salts, pesticides, metals, bacterial toxins, and human or animal medications are examples of chemical pollutants. Organisms in the water are biological pollutants. Other names for them include microorganisms and microbiological pollutants.In order to control corrosion, the system must take a variety of additional measures if lead concentrations reach an action threshold of 15 ppb or copper concentrations exceed an action level of 1.3 ppm in more than 10% of measured customer taps.
