24g of methane were burned in an excess of air. What mass of water would be produced in the reaction assuming complete combustion?Use the information below to answer the question.

Answer:

hey!

Explanation:

Hydrogen is the abundant in the Sun and in the large outer planets and hydrogen is the most abundant element in the universe as a whole, so at first sight it may seem strange that there is no significant gaseous hydrogen in earth’s atmosphere.

Hydrogen molecules can form on earth but do not exist as a star explode because because it's a very low density gas.

Answer:

The nucleus splits into two or more lighter nuclei, releasing kinetic energy, gamma radiation, and free neutrons. A portion of these neutrons may later be absorbed by other fissile atoms and trigger further fission events, which release more neutrons, and so on. This is known as a nuclear chain reaction.

Answer:

27.99 dm³

Explanation:

Applying

PV = nRT................ Equation 1

Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.

From the question, we were aksed to find V.

Therefore we make V the subject of the equation

V = nRT/P................ Equation 2

Given: n = 1.31 moles, T = 37°C = 310K, P = 904 mmHg = (904×0.001316) = 1.1897 atm

Constant: R = 0.082 atm.dm³/K.mol

Substitute these values into equation 2

V = (1.31×310×0.082)/(1.1897)

V = 27.99 dm³

Answer:

16.9g

Explanation:Cu+2AgNO3→2Ag+Cu(NO3)2  

Cu will likely have a +2 oxidation state. It is higher in the activity series than Ag, so it is a stronger reducing agent and will reduce Ag in a displacement reaction. Then you need to balance the coefficients knowing than NO3 is -1 and Ag is +1.

Then to calculate the theoretical yield you need to compare moles of the reactants:

m(Cu)=5g

M(Cu)=63.55

n(Cu)=5/63.55=0.0787

By comparing coefficients you require twice as much silver: 0.157mol

n(Ag)=0.157

M(Ag)=107.86

m(Ag)=0.157x107.86=16.9g

Hence, the theoretical yield of this reaction would be 16.9g

Answer:

A 15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°C to 175°C. What is the specific heat capacity of iron?

Explanation:

The amount of heat absorbed by the gold is 339.1 joules, which was calculated by the formula of specific heat capacity.

Specific heat capacity, often just called “specific heat”, is the amount of heat energy required to raise the temperature of one unit of mass of a substance by one degree Celsius (or one Kelvin).

To calculate the amount of heat absorbed by the gold, we can use the formula:

Q = m × c × ΔT

where:

Q = heat absorbed (in joules)

m = mass of the gold (in grams)

c = specific heat capacity of gold (in joules per gram per degree Celsius)

ΔT = change in temperature of the gold (in degrees Celsius)

The specific heat capacity of gold is 0.129 J/g°C.

Substituting the given values into the formula, we get:

Q = 15.5 g × 0.129 J/g°C × (177.4°C - 4.5°C)

Q = 15.5 g × 0.129 J/g°C × 172.9°C

Q = 339.1 J

Therefore, the amount of heat absorbed by the gold is 339.1 joules.

Explanation:

Because isotopes are each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei.

Answer:

Carbon is a versatile element and is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.

Explanation:

meaning of versatile: capable of or adapted for many different uses, skills, etc. 2 variable or changeable.

The versatile nature of carbon can be best understood with its features such as, tetravalency and catenation. In this section let us learn more about versatility of carbon.

Carbon is a versatile element and is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.

The two characteristic features seen in carbon, that is, tetravalency and catenation, put together give rise to a large number of compounds. Many have the same non-carbon atom or group of atoms attached to different carbon chains.

Catenation: The property of forming long chains by self-linking with other carbon atoms to form long chains, rings, double or triple bonds is called catenation.

Isomerism: Compounds with same molecular formula but different structural formula are called isomers. An isomerism commonly seen is due to difference in the arrangement of atoms or groups of atoms & is called structural isomerism. The 4 types of structural isomerism are:

 Chain isomerism

 Position

 Functional

Metamerism

Tetravalency: Carbon has 4 electrons in its valence shell. Energy considerations do not allow it to gain or lose 4 electrons; therefore it forms covalent bonds with other elements to complete its octet. This accounts for its tetravalency and explains its ability to form a variety of compounds.

Answer: 15N

Explanation:

The formula to calculate force in this scenario will be:

Force = Mass × Acceleration

where,

Mass = 6kg

Acceleration = 2.5m/s

We then put the values of mass and the acceleration in the formula. This will be:

F = ma

F = 6 × 2.5

F = 15N

Therefore, the force required to move the bowling ball will be 15Newton.

Answer: lucky fluoride

Explanation:

Answer: a) pH = 2.56 , acidic

b) pH = 2.38, acidic

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

[tex]pH=-\log [H^+][/tex]

a) [tex][H^+]=2.7\times 10^{-3}[/tex]

Putting in the values:

[tex]pH=-\log[2.7\times 10^{-3}][/tex]

[tex]pH=2.56[/tex]

Thus as pH is less than 7, the solution is acidic.

b) [tex][H^+]=4.1\times 10^{-3}[/tex]

Putting in the values:

[tex]pH=-\log[4.1\times 10^{-3}][/tex]

[tex]pH=2.38[/tex]

Thus as pH is less than 7, the solution is acidic.

Answer:

I think its A

Explanation:

The reaction is a first-order reaction with respect to "A" and an overall first-order reaction.

The rate law is given as Rate = k(A)ˣ, where k is the rate constant and x is the order of the reaction with respect to A.

Let's first find the initial rate for the first concentration of A, which is 0.35 mol/L.

1.6 mol/(L.s) = k(0.35 mol/L)ˣ   ....(i)

Now let's find the initial rate for the second concentration of A, which is 0.7 mol/L. We have:

3.2 mol/(L.s) = k(0.7 mol/L)ˣ   ....(ii)

Dividing equation (ii) by equation (i),

3.2 / (1.6) = (k(0.7)ˣ) / (k(0.35)ˣ)

2 = (0.7/0.35)ˣ

2 = 2ˣ

x = 1

Thus, the order of the given reaction with respect to A is 1.

Since the overall order of the reaction is added up to the orders of all the reactants.

Here, we only have one reactant, which is A, and its order is 1.

So, the overall order of the reaction is also 1.

Hence, the reaction is a first-order reaction with respect to "A" and an overall first-order reaction.
