(there are 2 quetions) how is heat being transfered in:
alekssr [168]

Answer:

  1. Heat energy is transferred from homes by conduction through the walls, floor, roof and windows. It is also transferred from homes by convection. For example, cold air can enter the house through gaps in doors and windows, and convection currents can transfer heat energy in the loft to the roof tiles.
  2. Convection is the heat transfer due to the movement of a fluid, such as a gas or liquid, and carries heat energy away from the source of heat. When a substance is heated, it causes its particles to vibrate more. The more vibration, the more space they will take up and the less dense they will become.

I really hope it helps! ❤

Why do elements such as Neptunium, Plutonium, Californium, Einstenium, Bohrium, Flerovium, Radon, Oganesson, and a few others ha
noname [10]

All the elements you listed share a common trait: they are synthetic, radioactive elements. These elements do not have a stable isotope, so for a radioactive element, its most stable isotope's atomic mass will be listed in parentheses.

One such example would be plutonium. This element has 6 different isotopes with differing half-lives. The most stable isotope for plutonium is plutonium-244, with a half-life of around 80 million years. Therefore, the atomic mass listed for plutonium will be (244).

When a mixture of glucose 6-phosphate and fructose 6-phosphate is incubated with the enzyme phosphohexose isomerase, the final m
Anastasy [175]

Answer:

The correct option is B

Explanation:

The reaction is given as

             Glucose\ 6-phosphate ---->fractose \ 6-phosphate

The equilibrium constant for this reaction is mathematically represented as

               K_c = \frac{[concentration \ of  \ product ]}{concentration \ of  \ reactant } = \frac{[fructose \ 6 -phosphate]}{[Glucose \ 6 - phosphate]}

From the question we are told that

    [Glucose 6-phosphate] = 2 × [fructose 6-phosphate]

So  

      K_c  = \frac{[fructose \ 6 -phosphate]}{[2 (fructose \ 6 -phosphate)]} = 0.5

Generally change in free energy \Delta G is mathematically represented as

          \Delta G = - RTlnK_c

Given that T = 298 K

                 R = 8.315 J/mol·K

        \Delta G = -8.314 * 298 * ln (0.5)

               = -1717.32 J/mol

               = -1.7 \ kJ/mol
