given this information, what structure is most likely part of a larger molecule responsible for increasing the rate of the glycolytic pathway in eukaryotes?

The specific heat of the metal can be calculated using calorimetric equation. The specific heat of the metal here is 0.61 J/g °C.

The specific heat capacity of  substance is the heat energy required to raise its temperature by one degree Celsius per one gram  of the substance.

The calorimetric equation connecting the heat energy q, mass m, specific heat c and temperature difference ΔT is:

q = m c  ΔT

Here, the heat released from the metal is equal to the heat absorbed by water.

Therefore,

q metal = q water. Let c  be the specific heat of the metal.

25 g  × ( 99 - 20.15°C) ×c = 50 g  × ( 20.15°C- 14.33) × 4.18 J/g °C

                                         = 1217.5 J

Then c = 1217.5 J/25 g  × ( 99 - 20.15°C)  = 0.61 J/g °C.

Therefore, the specific heat of the metal is 0.61 J/g °C.

Answer:

28.9 moles of KClO3 x (3 moles O2 / 2 moles KClO3) = 43.35 moles of O2

To convert moles to grams, you'll need to use the molar mass of O2, which is 32 g/mol.

43.35 moles x 32 g/mol = 1387.2 g of O2

So from 28.9 moles of KCiO3 , 1387.2 grams of O2 will be formed.

The mass of air with the given specification in kilograms of the air in a room is 286.0165 kg/m³.

A huge volume of atmospheric air that is largely uniform in temperature and moisture is known as an air mass. Air masses can travel tens of thousands of kilometers in any direction and go as high as the stratosphere. The unit of dynamic mass per time known as mass flow is grams per minute (g/min). It is possible to calculate an exact mass flow by comparing a volumetric flow (cm3/min) to its known temperature and pressure.

Given:

Convert the units of feet into meters:

1 foot=12 inches, 1inch-2.54 cm, 100 cm=1m

28.0 feet = 8.5344 m

32.0 feet = 9.753 m

9.5 feet = 2.895 m

Volume= 8.53 × 9.75 × 2.89 or 240.35 m³

mass of air= 1.19g/0.001 m³ × 240.35 or 286.0165 kg/m³

Answer:

The mass of the solid sample is 4.442 g (5.853 g - 1.411 g).

Explanation:

The mass of the solid sample can be determined by subtracting the mass of the weigh boat from the mass of the weigh boat and sample. This is because the weigh boat is a constant and known value, and it is used as a reference to measure the mass of the sample. To find the mass of the sample, we use the formula:

Mass of sample = Mass of weigh boat and sample - Mass of weigh boat

In this scenario:

Mass of sample = 5.853 g - 1.411 g = 4.442 g

Therefore, the mass of the solid sample is 4.442 g.

Assuming that the ideal Brayton cycle begins with isentropic compression, the remaining processes in order to complete the closed-loop Brayton cycle are:

The Brayton cycle is a thermodynamic cycle used to model the operation of a gas turbine engine. In the Brayton cycle, a working fluid is compressed, heated, expanded and cooled in a closed loop. The Brayton cycle is an idealized cycle, and in reality the processes are not completely isentropic, isothermal or adiabatic.

The cycle begins with isentropic compression of the working fluid, where the pressure and temperature of the fluid increase. The working fluid is then heated at constant pressure, and the temperature increases further. The working fluid is then expanded isentropically, converting the heat energy into work. The working fluid is then cooled at constant pressure, and the temperature and pressure decrease. Finally, the working fluid is recompressed isentropically, returning it to the original state.

The equilibrium concentration of H₃O⁺ in a 0.20 M solution of oxalic acid is equal to 0.11 moldm⁻³.

Let [[tex]HA_{c}[/tex] ] represent oxalic acid and [[tex]A_{c} ^{-}[/tex] ] represent oxalate ion,

Then,

[tex]K_{a}[/tex] = [H₃O⁺] × [[tex]A_{c} ^{-}[/tex]] /  [[tex]HA_{c}[/tex]]  

So during the first dissociation,

5.9 × 10⁻² =  [H₃O⁺] × [[tex]A_{c} ^{-}[/tex]] / 0.2

So,

0.118 = [H₃O⁺]²

As,  [H₃O⁺] ion as well as the respective anion must be existing in a 1:1 ratio in solution, therefore,

0.1086 = [H₃O⁺]  = [[tex]A_{c} ^{-}[/tex]]

In the second dissociation,

6.4 × 10⁻⁵ = [H₃O⁺] × [[tex]B_{c} ^{-}[/tex]] / 0.1086

[H₃O⁺] = 0.002637
