Answer:

34.8 moles of CO₂ are produced

Explanation:

This is the reaction:

1C₅H₁₂ + 8O₂  →  6H₂O  +  5CO₂

Ratio is 1:5. We make a rule of three

1 mol of pentane can produce 5 moles of CO₂

Then, 6.96 moles of pentane may produce (6.96 .5) / 1 = 34.8 moles

A sheet of gold weighing 8.8 g and at a temperature of 10.5°C is placed flat on a sheet of iron weighing 19.5 g and at a tempera
timofeeve [1]

Answer:

T = 36.393\,^{\textdegree}C

Explanation:

The contact between the sheet of gold and the sheet of iron allows a heat transfer until thermal equilibrium is done, which means that both sheets have the same temperature:

-Q_{iron} = Q_{gold}

-(0.008\,kg)\cdot (452\,\frac{J}{kg\cdot ^{\textdegree}C} )\cdot (T-54.4\,^{\textdegree}C) = (0.0195\,kg)\cdot (129\,\frac{J}{kg\cdot ^{\textdegree}C} )\cdot (T-10.5\,^{\textdegree}C)

-(3.616\,\frac{J}{^{\textdegree}C})\cdot (T-54.4\,^{\textdegree}C) = (2.515\,\frac{J}{^{\textdegree}C})\cdot (T-10.5^{\textdegree}C)

-1.438\cdot (T - 54.4^{\textdegree}C) = T-10.5^{\textdegree}C

-1.438\cdot T +78.227^{\textdegree}C = T - 10.5^{\textdegree}C

2.438\cdot T = 88.727\,^{\textdegree}C

The final temperature is:

T = 36.393\,^{\textdegree}C

Which chemical equation represents a decomposition reaction?
MrMuchimi

Decomposition reaction D. 2H20⇒ 2H2 + O2

<h3>Further explanation </h3>

Every chemical reaction involves a compound consisting of reactants and products  

Reactants are compounds that react and form new compounds called products

There are several forms of reactions that can occur, including single replacement, double replacement, synthesis, decomposition, etc.

A. 2C2H6 + 702 ⇒ 4CO2 + 6H20

Combustion : reaction of Hydrocarbon and Oxygen

B. AgNO3 + LiCl → AgCl + LINO3

Double replacement : there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

C. Ca + MgS → CaS + Mg

Single replacement :one element replaces the other elements of a compound to produce new elements and compounds

D. 2H20⇒ 2H2 + O2

Decomposition : One compound breaks down into 2 components

A major textile dye manufacturer developed new yellow dye. The dye has a percent composition of 75.9 5% C, 17.72% N
AnnZ [28]

Answer:

Such molecule must have molecular formula of C15N3H15

Explanation:

Mass of carbon in such molecule

0.7595*240_{g/mol} =182.28_{g C/mol}

The atomic mass of carbon is 12.01 g/mol, so in 182.28 g of carbon there is 15.18 mols of carbon.

Mass of Nitrogen in such molecule

0.1772*240_{g/mol} =37.73_{g C/mol}

The atomic mass of nitrogen is 14.01 g/mol, so in 42.53g of nitrogen there is 3.04 mols of nitrogen.

Mass of Hydrogen in such molecule

0.0633*240_{g/mol} =15.19 {g C/mol}

The atomic mass of Hydrogen is 1.00 g/mol, so in 15.19 g of Hydrogen there is 15.19 mols of Hydrogen.

Such molecule must have molecular formula of C15N3H15

The mechanism for producing a concentrated urine involves all of the following except
avanturin [10]

Answer:

The correct answer is "obligatory water reabsorption in the proximal convoluted tubule".

Explanation:

The mechanism for producing concentrated urine cannot include the obligatory reabsorption of water in the proximal convoluted tubule since this process is part of the nephron, the system that filters the blood. Glucose and amino acids are reabsorbed almost entirely, as are approximately 70% of filtered potassium and 80% of bicarbonate.

Have a nice day!
