The mass of NaCl in 44mL of a 1.6M solution is 4.1grams.

The mass of NaCl can be calculated by using the following formula;

Molarity = no. of moles ÷ volume

Molarity is the concentration of a substance in solution, expressed as the number moles of solute per litre of solution.

no of moles = 1.6M × 0.044L = 0.07moles

The mass of the sodium chloride solution can be calculated by multiplying the molar mass of the salt by the number of moles present in the solution.

The molar mass of NaCl solution can be calculated as follows;

M.M = 23g/mol + 35.5g/mol = 58.5g/mol

mass of NaCl = 58.5 × 0.07 = 4.1grams.

Therefore, 4.1grams is the mass of NaCl solution.

The thiosulfate reaction is endothermic while the sodium hydroxide reaction is exothermic.

An endothermic reaction is one in which the temperature decreases as time increases while an exothermic reaction is one in which the temperature increases as time increases.

We can see that the reaction involving the thiosulfate is an endothermic reaction because the temperature was decreased as time increased while the reaction involving the sodium hydroxide is an exothermic reaction because the temperature increased as time increased.

The question requires us to identify the type nuclear decay that releases a photon of light energy and does not change the atom's mass or atomic number.

As we are talking about a nuclear decay that doesn't provoke a change in the atom's mass or atomic number, we can rule out both alpha and beta decay. Remember that an alpha particle contains two protons and two neutros, therefore an alpha decay changes both mass and atomic number. Similarly, the emission of an beta particle also changes the atomic number.

Then, we can analyze the remaining options: gamma decay and electron capture decay.

Electron capture decay is i process in which a proton-rich nucleus of an electrically neutral atom absorbs an inner atomic electron, causing the change of a proton to neutron and causes the emission of a neutrino.

Gamma decay, on the other side, an atomic nucleus changes from a higher energy-state to a lower energy-state through the emission of electromagnetic radiation (a photon). Since it doesn't occur the emission of a particle, there is no change to the number of protons or neutrons and the atom's mass and atomic number remains unchanged.

Therefore, the best option would be letter A, "Gamma decay".

According to the figure, in the radioactive decay of Uranium, 8 alpha y 6 beta particles are produced in the process. This is shown as an outgoing arrow between each element transition.

Answer:

11.9g remains after 48.2 days

Explanation:

All isotope decay follows the equation:

ln [A] = -kt + ln [A]₀

Where [A] is actual amount of the isotope after time t, k is decay constant and [A]₀ the initial amount of the isotope

We can find k from half-life as follows:

k = ln 2 / Half-Life

k = ln2 / 27.7 days

k = 0.025 days⁻¹

t = 48.2 days

[A]  = ?

[A]₀ = 39.7mg

ln [A] = -0.025 days⁻¹*48.2 days + ln [39.7mg]

ln[A] = 2.476

The half-life of Po-210 is 140 days. If the initial mass of the sample is 5 kg, 3.5g will remain after 280 days.

Chemical kinetics is a subfield of physical chemistry that studies the speeds of chemical processes. The rate of the reaction may be used to classify it as quick, moderate, or sluggish. Reaction mechanism also enables us to study the effects of temperature and catalyst on reaction rate and rate constant. It informs us about reaction processes and enables us to apply particular rate constants to certain mechanistic stages.

The rate law for first order kinetics is

K=(2.303/T)×log(a/a-x)

half life=0.693/K

Where

k - rate constant

t - time passed by the sample

a - initial amount of the reactant

a-x - amount left after the decay process

K=0.693/half life

K=0.693/140

=0.086

0.086=(2.303/ 280)×log( 5 /a-x)

0.086=0.07×log( 136/a-x)

1.22=log( 136/a-x)

136/a-x=16.5

a-x=3.5g

The metal X has an approximate molar mass of 42.36 g/mol and the metal is most likely calcium.

The molar mass of the metal carbonate XCO₃ and identify the metal X, we need to calculate the number of moles of XCO₃ and CO₂ using the given masses and molar masses.

The molar mass of CO₂ (carbon dioxide) is 12.011 g/mol (for carbon) + 2 * 15.999 g/mol (for oxygen) = 44.01 g/mol.

The number of moles of CO₂ can be calculated using the formula:

moles of CO₂ = mass of CO₂ / molar mass of CO₂

moles of CO₂ = 0.855 g / 44.01 g/mol

moles of CO₂ ≈ 0.01944 mol

Since the reaction stoichiometry is 1:1 between XCO₃ and CO₂, the number of moles of XCO₃ is also approximately 0.01944 mol.

molar mass of XCO₃ = mass of XCO₃ / moles of XCO₃

molar mass of XCO₃ = 2.012 g / 0.01944 mol

molar mass of XCO₃ ≈ 103.38 g/mol

The molar mass of XCO₃ is approximately 103.38 g/mol.

To determine the metal X:

molar mass of X = molar mass of XCO3 - molar mass of CO3

molar mass of X = 103.38 g/mol - (12.011 g/mol + 3 * 15.999 g/mol)

molar mass of X ≈ 42.36 g/mol

The best description of the relationship between population size, carrying capacity, and limiting factors is: "The size of a population usually stays near its carrying capacity due to limiting factors."

Carrying capacity refers to the maximum number of individuals that a particular environment can sustainably support. It represents the limit to which a population can grow given the available resources, such as food, water, and habitat. Limiting factors, on the other hand, are the factors that restrict population growth by reducing birth rates, increasing death rates, or limiting access to resources.As a population approaches its carrying capacity, limiting factors come into play and regulate the population size. These limiting factors can include competition for resources, predation, disease, availability of suitable habitat, and other environmental factors. They act as checks on population growth, preventing it from exceeding the carrying capacity of the ecosystem.

Therefore, the size of a population usually stays near its carrying capacity because the limiting factors ensure that the population does not exceed the available resources and ecological limits of the environment. If the population surpasses the carrying capacity, the limiting factors will intensify, causing a decline in resources and an increase in mortality rates, which ultimately brings the population back towards the carrying capacity.It's important to note that the relationship between population size, carrying capacity, and limiting factors is dynamic and can vary depending on various ecological and environmental factors.

Answer: a)  \(Fe\) is the limiting reagent

b) 3.59 g

c) 11.6g

Explanation:

\(4Al_2O_3+9Fe\rightarrow 3Fe_3O_4+8Al\)  

To calculate the moles :

\(\text{Moles of} Al_2O_3=\frac{27.5g}{102g/mol}=0.27moles\)

\(\text{Moles of} Fe=\frac{8.4g}{56g/mol}=0.15moles\)

According to stoichiometry :

a) 9 moles of \(Fe\)  require= 4 moles of \(Al_2O_3\)

Thus 0.15 moles of \(Fe\) will require=\(\frac{4}{9}\times 0.15=0.067moles\)  of \(Al\)

Thus \(Fe\) is the limiting reagent as it limits the formation of product and \(Al\) is the excess reagent.

b) As 9 moles of \(Fe\) give = 8 moles of \(Al\)

Thus 0.15 moles of \(Fe\) give =\(\frac{8}{9}\times 0.15=0.133moles\)  of \(Al\)

Mass of \(Al=moles\times {\text {Molar mass}}=0.133moles\times 27g/mol=3.59g\)

c) As 9 moles of \(Fe\) give = 3 moles of \(Fe_3O_4\)

Thus 0.15 moles of \(Fe\) give =\(\frac{3}{9}\times 0.15=0.05moles\)  of \(Fe_3O_4\)

Mass of \(Fe_3O_4=moles\times {\text {Molar mass}}=0..05moles\times 231.5g/mol=11.6g\)
