Use the electron-transfer method to balance the equation involving the reaction of lithium with water to produce lithium hydroxide and hydrogen gas.
Answers
Answer:
Explanation:
The equation for the reaction of lithium with water to produce lithium hydroxide and hydrogen gas is:
Li + H2O -> LiOH + H2
To balance this equation using the electron-transfer method, we first need to determine the oxidation states of each element in the reactants and products.
In Li, the oxidation state of lithium is +1. In H2O, the oxidation state of hydrogen is +1 and oxygen is -2.
In LiOH, the oxidation state of lithium is +1, oxygen is -2 and hydrogen is +1.
In H2, the oxidation state of hydrogen is +1.
It's clear that lithium loses 1 electron to become Li+ and hydrogen gains 1 electron to become H-.
So, we have to add an electron on the right side of the equation to balance the electrons.
Li + H2O -> LiOH + H2 + e-
Now, the number of electrons on both sides of the equation is the same and the equation is balanced.
Alternatively, we can use the oxidation number method, where we balance the charge of the reactant and product side of the equation. The sum of the oxidation numbers of all atoms on the reactant side must equal the sum of the oxidation numbers of all atoms on the products side. In this case, the oxidation state of lithium is +1, hydrogen is +1 and oxygen is -2.
Li + H2O -> LiOH + H2
+1 +1 -2 = +1 +1 +1 -2
The equation is already balanced with respect to oxidation numbers
how you would make 700ml of a 0.75m nacl solution?
Answers
To make 700 mL of a 0.75M NaCl solution, the following steps should be taken:
Step 1: Calculate the molecular weight of NaCl.
The molecular weight of NaCl is the sum of the atomic weights of Na and Cl.
Molecular weight of NaCl = atomic weight of Na + atomic weight of Cl.
Molecular weight of NaCl = (22.99 + 35.45) g/mol = 58.44 g/mol
Step 2: Calculate the number of moles of NaCl required.
To calculate the number of moles, use the formula: Number of moles = desired Molarity x volume (in liters)
Number of moles = 0.75 M x 0.7 L (700 mL = 0.7 L) = 0.525 moles
Step 3: Calculate the mass of NaCl required.
To calculate the mass, use the formula: Mass = number of moles x molecular weight
Mass = 0.525 mol x 58.44 g/mol = 30.69 g
Step 4: Dissolve 30.69 g of NaCl in enough water to make 700 mL of solution.
Dissolve 30.69 g of NaCl in enough water to make 700 mL of solution.

T(K) k(M^-1 s^-1)
352 109 426 185 Determine the activation energy for this reaction Express your answer with the appropriate units.
_____
Answers
Using the Arrhenius equation, we must plot ln(k) versus 1/T and estimate the slope of the resulting line to determine the activation energy for the reaction.
The following is the Arrhenius equation:
ln(k) = -Ea/(R*T) + ln(A)
Where:
k is the rate constant
Ea is the activation energy
R is the gas constant (8.314 J/(mol*K))
T is the temperature in Kelvin
A is the pre-exponential factor or frequency factor
The values of k at two different temperatures—352 K and 426 K—are given. These facts allow us to determine the activation energy.
Taking the natural logarithm of both sides of the Arrhenius equation gives us:
ln(k) = -Ea/(R*T) + ln(A)
Rearranging the equation to isolate Ea, we get:
ln(k) + Ea/(R*T) = ln(A)
Now that we have ln(k) versus 1/T, we can calculate the slope of the line. Rearranging the equation allows us to find the activation energy E since the slope of the line is equal to -Ea/(R).
Plot ln(k) on the y-axis and 1/T on the x-axis using the values provided. To determine the activation energy (Ea) in the correct quantity (J/mol or kJ/mol), calculate the slope of the line and multiply the result by the gas constant (R).

Answer: The reaction that occurs at anode is \(Zn(s)\rightarrow Zn^{2+}(aq.)+2e^-\)
Explanation:
Given : \(E^o_{Zn^{2+}/Zn}=-0.76V\)
\(E^o_{Cu^{2+}/Cu}=+0.34V\)
The substance having highest positive reduction potential will always get reduced and will undergo reduction reaction. Here, copper will undergo reduction reaction will get reduced.
The substance having highest negative reduction potential will always get oxidised and will undergo oxidation reaction. Here, zinc will undergo oxidation reaction will get oxidised.
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
Oxidation half reaction (anode) : \(Zn(s)\rightarrow Zn^{2+}(aq.)+2e^-\)
Reduction half reaction (cathode) : \(Cu^{2+}(aq.)+2e^-\rightarrow Cu(s)\)

Answers
Answer:
See below.
Explanation:
Acceleration is the change in velocity over a period of time.
Let vi be the initial velocity.
Let vf be the final velocity.
t is the time it took to go from vi to vf.
Acceleration is (vf-vi)/t
If the initial velocity was 2 cm/s and the final velocity was 10 cm/s, the object would have incresed it's velocity by (10 - 2) or 8 cm/s. If iit took 10 seconds to reach vf, the acceleration would be:

The table showing composition of four atoms has different number of protons, electrons, and neutrons. On the basis of the information given in the table, Mystery atom 1! 15! 15! 15! and the mystery atom 2! 17! 16! 15! are of the same element because they have same number of neutrons.
Atoms do not always contain same number of electrons and protons, but the number of neutrons in an atom is always same unless there is possibility of an isotope.
When number of electrons and protons is same in an atom, it do not carry charge and is called as a neutral atom. When number of electrons is more, atom carries a negative charge and when number of protons is more, the atom carries a positive charge.
Electrons have negative charge, protons have a positive and neutrons do not carry any charge. As opposite charges attract, electrons and protons attract each other. Addition or removal of neutrons from the nucleus does not bring the change in the electrical charge of the nucleus.
In atom 1 and 2, number of neutrons is same and electrons are more in atom 2. Therefore, it carries negative charge and it is a charged atom of same element as atom 1.

_____________states that when two elements react to form more than one compound, a fixed mass of one element will react with masses of the other element in a ratio of small, whole numbers.
Answers
The law of multiple proportions states that when two elements react to form more than one compound, a fixed mass of one element will react with masses of the other element in a ratio of small, whole numbers.
According to the law of multiple proportions, if two elements (A and B) react to form two compounds, the ratio of the masses of B that combine with a fixed mass of A can be expressed as a ratio of small whole numbers.
For example, consider the compounds carbon monoxide (CO) and carbon dioxide (CO2), which both contain carbon and oxygen. The ratio of oxygen atoms in CO to CO2 is 1:2. The law of multiple proportions is important in understanding how elements combine to form different compounds.
It helps chemists predict the chemical formulas of compounds and determine the relative amounts of reactants needed to produce a particular product. Additionally, it helps explain why some compounds have the same elements but different properties, such as carbon monoxide and carbon dioxide.

When the plant or animal dies, they stop absorbing, but the radioactive carbon that they've accumulated continues to decay.
What is the principle of carbon dating?Radiocarbon dating works by comparing the three different isotopes of carbon.

Laboratory equipment and work benches are cleaned (and stored properly in the case of equipment) after use so as to keep them free of the purpose it has been used for, which if not done, could lead to various undesirable events/aftermath. For example, if dyes or grease is used in a process in the laboratory, these compounds need to be washed off the glasswares (like measuring cylinder) it was poured in during the course of the experiment to prevent the glassware from retaining some of it's residual particles hence contaminating the glassware for future laboratory use. Cleaning must be done on the surfaces the experiment was carried out also for the same reason.
