A boat that was sailing at 420 meters per minute passed near a humpback whale. The whale had taken 2.5 minutes to swim 230 meters south at a constant velocity. What was the whale's velocity?
PLSS help!!!
The velocity of the whale is equal to 1.53 m/s.
What is the velocity?Velocity can be defined as a vector measurement of the direction and position of an object. The velocity can be defined as the rate of change in the position w.r.t. time.
Velocity is a vector parameter as it possesses both magnitude and direction. A mathematical formula to determine velocity:
v = d / t
Where v is the velocity, d is the distance, and t is the time of an object.
The S.I. unit for velocity is meters per second (m/s) and can also express in miles/hour (mph), and kilometers/hour (kph).
Given the distance swum by the whale, d= 230 m
The time is taken by the whale, t = 2.5 min = 150 sec

Why can you not selectively epoxidize an alkene with mcpba in the presence of a ketone?.
mCPBA is a useful reagent for epoxide formation and ketone-to-ester formation. It epoxidizes alkene to epoxide and also oxidizes ketone to ester. So we can't selectively epoxidize an alkene if both alkene and ketones are present.
Purified mCPBA is a useful reagent for the oxidation of various classes of aldehydes. α-branched aliphatic aldehydes undergo Baeyer-Villiger oxidation to form formates. α-branched α,β-unsaturated aldehydes yield enol formates and/or epoxides, and α-hydroxylated aldehydes yield ketones.
Most aldehydes and ketones have a low ceiling temperature below ambient temperature. That is, these compounds do not polymerize above room temperature. MCPBA is a strong oxidant comparable to other peracids. The advantage of 3-chloroperbenzoic acid is its handling.

Considering the definition of isotopes and atomic mass of an element, the percent of each isotope is 16.5% abundant for Camerium-111 and 83.5% abundant for Camerium-113.
Definition of isotopeThe same chemical element can be made up of different atoms, where their atomic numbers are the same, but the number of neutrons is different. Thus the isotopes of the element are formed.
Definition of atomic massThe atomic mass of an element is the weighted average mass of its natural isotopes. This is, the atomic mass of a chemical element is usually calculated as the weighted average of the masses of the different isotopes of each element, considering the relative abundance of each of them.
Atomic mass of the element in this caseIn this case, you know:
Camerium-111 is x% abundant (the atomic mass is 111).Camerium-113 is (100-x)% abundant (the atomic mass is 113).The average isotopic mass is 112.67 amu.Then, the average mass can be expressed as:
111x + 113×(1-x)= 112.67

a chemistry student prepared lead(ii) iodide from 10.0 g of lead(ii) nitrate and aqueous potassium iodide. part a if the student collected 12.6 g of pbi2 and the theoretical yield is 13.9 g , what is the percent yield?
The percent yield of lead (II) iodide is 90.6 %.
A insoluble lead (II) iodide salt is produced as this is a precipitation reaction.
The balanced chemical equation for this reaction is given as:
Pb(NO₃)₂ (aq) + 2 KI (aq) → PbI₂ (s) + 2 KNO₃ (aq)
Moles of Pb(NO₃)₂ in the reactant side = 10 × 1/331.2 g = 0.0302 mol

Calcium chloride solution is a electrolyte solution.
An electrolyte solution is a solution that generally contains ions, atoms or molecules that have been lost or gained electrons during the reaction, and is electrically conductive. Because of this they are often called ionic solutions, however there are some cases where the electrolytes are not ions.
A non-electrolyte is a solute that does not dissociate, or which does not furnishes ions during the dissolving process. Therefore, solutions that are generated through the solvation of non-electrolytes do not contain ions and, instead they are called as neutral molecules.

A saturated solution of lead (ii) nitrate was made at 500c using 100g of water and then allowed to cool to 300c. What would happen to the solution as the temperature is decreased?.
The temperature of the solution decreases with the precipitation of solid lead nitrate in the solution.
Therefore, when a saturated solution of lead nitrate prepared at 50°C is cooled to 30°C solid lead nitrate is observed to segregate into the solution. This means that as the temperature decreases, so does the solubility of lead nitrate. The solubility of substances is directly affected by the temperature of the solvent.
The average kinetic energy of the molecules that make up the solution increases as the temperature of the solution increases. The increased kinetic energy allows solvent molecules to break down solute molecules bound by intermolecular interactions. A dissolution process is endothermic if the energy released when a water molecule bonds with a solute are less than the energy used to pull the solute apart.

The final pressure can be calculated using Boyle's law. The final pressure of the gas if the volume is increased from 3.98 L to 5.30 L is obtained as 526.4 mmHg.
What is Boyle's law?Boyle's law states that at constant temperature, the volume of a gas is inversely proportional to the pressure of the gas. Hence, volume decreases with increase in pressure and vice versa.
If P₁ and V₁ be the initial pressure and volume respectively and P₂, V₂ be their final quantities, then the relation between them can be written as:
P₁ V₁ = P₂ V₂ .
It is given that the initial volume and pressure is 3.98 L and 701 mmHg, and the final volume is 5.30 L. Then, the final pressure is calculated as follows:
P₂ = P₁ V₁ / V₂
= (3.98 L × 701 mm Hg) / 5.30 L
= 526.4 mmHg.
Hence, the final pressure of the gas will be 526.4 mmHg.

A sample of gas has an initial volume of 3.98 L at a pressure of 701 mmHg If the volume of the gas is increased to 5.30 L, what is the pressure? (Assume constant temperature.)
Combusting an unknown hydrocarbon produces 5 mol co₂ and 6 mol h₂o. What is the empirical formula of the hydrocarbon?.
The empirical formula of the given hydrocarbon is CH2 .
What is a combustion reaction?
A fuel (the reductant) and an oxidant, typically atmospheric oxygen, undergo a high-temperature exothermic redox chemical reaction that results in oxidized, frequently gaseous products and a mixture known as smoke. Since a flame only appears when substances undergoing combustion evaporate, combustion does not always result in fire, but when it does, a flame is a distinctive sign of the event. The heat from a flame may be enough energy to make the reaction self-sustaining, even though the activation energy must be overcome to initiate combustion (such as when using a lit match to start a fire).
A convoluted series of simple radical reactions frequently occurs during combustion.
The given reaction is ,
CH2(g)+3O2(g)→2CO2(g)+2H2O(I)
Hence, the empirical formula of the given hydrocarbon is CH2 .
