which of the following happen when you heat a solid

Answer:

The rate law is:

[tex]\displaystyle \text{Rate} & = k[A]^2[B][/tex]

Doubling the concentration of C will have no effect on the rate of the reaction.

Explanation:

We want to write the rate law for the reaction:

[tex]\displaystyle A + B + C \longrightarrow D + E[/tex]

Where the order of A, B, and C are 2, 1, and 0, respectively.

The rate law will have the form:
[tex]\displaystyle \text{Rate} = k [A]^m[B]^n[C]^p[/tex]

Where m, n, and p are their respective order of reactions.

Hence, the rate law is:
[tex]\displaystyle \begin{aligned} \text{Rate} & = k[A]^2[B][C]^0\\ \\ & = k[A]^2[B] \end{aligned}[/tex]

Because the order of reaction to C is 0, changing its concentration will have no effect on the rate law.

Explanation:

Nitrates and nitrites are interrelated by oxidation reduction; nitrite is the breakdown product of nitrate. Many experts believe that nitrates are relatively harmless until they break down into nitrites.

Answer:

The proton determines the identity of an element.

Answer:

25 percent solution by mass of ethanol means that 100 gram of solution contains 25 gram of solute i.e-ethanol. Now,as the density of the solution is 1 g/ml so 100 g of the solution has a volume of 100 ml. So,we have 25 gram of ethanol in 100 ml of the solution. So we have 250 g of ethanol in 1 litre of solution.

Explanation:

The major 3 steps in determining the mass of a product from a given mass of a reactant would be to find the balanced equation of the reaction, determine the mole ratio of the reactant to the product, and then use the equivalent mole of the product from the reactant to find the desired variable.

With a given mass of a reactant, the mass of a product from a reaction can be determined in 3 major steps:

From there, the equivalent number of moles of the product can be used to find the mass of the product by multiplying with the molar mass of the product.

Although we do not have the graph needed to answer this question, we can confirm that if the toy were to be accelerating, one should see this on the graph as a curved line.

When graphing motion in terms of distance over time, we can use the shape of the line in the graph to determine if the speed is constant or if there is an acceleration present. If the line is straight, the speed is constant, but if there is a curve, there will be acceleration.

Therefore, we can confirm that if the toy were to be accelerating, one should see this on the graph as a curved line.

Answer:

the scrubby plants in the chaparral biome fix CO2 from the atmosphere through photosynthesis and store carbon as starch. The energy from these carbohydrates is passed on to animals and insects that consume the plants. These primary consumers will pass on the carbon’s energy to other animals that prey on them. When plants or animals die and decompose, the carbon in their bodies returns to the earth. Fossil fuels, which are made from ancient decomposed matter, release carbon back into the atmosphere as CO2 when they are burned

The density of the larger broken piece from the original piece would remain 1.500 g/cm3

Density = mass/volume

The ratio of mass to the volume of a substance is constant.

Thus, for the long glass stirring rod, a reduction in the length means a reduction in its volume. Also, there would be a commensurate reduction in the mass of the glass rod.

At the end of the day, the ratio of mass/volume of the glass rod, be it the larger or the smaller piece, remains the same.

Thus, the density would remain 1.500 g/cm3.

Explanation:

Besides that initial consideration there is solar energy being added to the reaction which might be worth noting.

More important to note is that organic molecules/compounds such as glucose are higher in order compared to inorganic molecules/compounds such as water.

H(g)

Generally the equation for the Change in Heat energy  is mathematically given as

dG=dH-TdS

Where

dH=CpdT

Therefore, With no change in entalpy dH only changes  when there is a change in dT

dS=CpInT

With dS independent of pressure S is constant

Hence, dG=dH-TdS remains the same

Explanation:

Answer:

the answer is themodynamics

Answer:

molar mass of CaCO3=40+12+3(16)

=100 gmol-1

Ca percent composition=40/100*100%

=40%

C percent composition=12/100*100%

=12%

0 percent composition=48/100*100%

=48%

Answer:

Since we're sticking with theoretical values instead of experimental, Percent Composition would be (Molar Mass of the element) / (Molar mass of compound) x 100%

Molar mass of Calcium: 40g/mol

Molar mass of Carbon: 12g/mol

Molar mass of Oxygen: 16g/mol

Molar mass of CaCO3 (Calcium Carbonate) = (40) + (12) + (16)*3 = 100g/mol

Percentage composition of Calcium = [tex]\frac{40}{100} \ * \ 100 =[/tex] 40% of Calcium

Percentage composition of Carbon = [tex]\frac{12}{100} \ * \ 100 =[/tex] 12% of Carbon

(For the next one, there are 3 oxygen, so it'd be 16x3 = 48g/mol)

Percentage composition of Oxygen = [tex]\frac{48}{100} \ * \ 100 =[/tex] 48% of Oxygen
