Answer:

7.3*10^2 K = 457 C = 854.33 F

Explanation:

<u>Given:</u>

Surface temperature on sun = 7.3*10^2 K

<u>To determine:</u>

The temperature in degrees C and Kelvin

<u>Calculation:</u>

To convert Kelvin(K) to degrees Celsius (°C)

C = K -273----(1)

To convert Kelvin(K) to degrees Fahrenheit (F)

F = K*\frac{9}{5}-459.67----(2)

Based on equation (1):

C = 730 -273 = 457 C

Based on equation (2)

F = 730*\frac{9}{5}-459.67=854.33 F

Wetlands are able to remove nutrients and chemicals from water as the water flows through the area. A developer is planning to d
MakcuM [25]

Destroying the wetlands will reduce the bay's water quality and vegetation will not grow effectively near bay as a result of which ecosystem will also destroy.

<h3>What is ecosystem?</h3>

All species and the physical environment with which they interact make up an ecosystem.

  • Nutrient cycles and energy flows bind these biotic and abiotic components together.
  • Photosynthesis brings energy into the system, which is absorbed into plant tissue.

As it is already mentioned that, water of the wetlands was carry nutrients which in turn was taken up by plants and vegetation, and if it will destroyed near a bay then the vegetation of that place will destroy as they will not get proper nutrients, which in turn also affects the ecosystem.

Hence destroying the wetlands will reduce the bay's water quality and vegetation will not grow effectively near bay as a result of which ecosystem will also destroy.

isolated system (plural isolated systems) (physics) A system that does not interact with its surroundings. Depending on context this may mean that its total energy and/or momentum stay constant.

Explanation:

An isolated system is a thermodynamic system that cannot exchange either energy or matter outside the boundaries of the system. ... The system may be enclosed such that neither energy nor mass may enter or exit.

Gaseous hydrogen iodide is placed in a closed container at 425∘C, where it partially decomposes to hydrogen and iodine: 2HI(g)⇌H
murzikaleks [220]

Answer:

0.0184

Explanation:

Let's consider the following reaction at equilibrium.

2 HI(g) ⇌ H₂(g) + I₂(g)

The concentration equilibrium constant (Kc) is equal to the product of the concentration of the products raised to their  stoichiometric coefficients divided by the product of the concentration of the reactants raised to their  stoichiometric coefficients.

Kc = [H₂] × [I₂] / [HI]²

Kc = (4.78 × 10⁻⁴) × (4.78 × 10⁻⁴) / (3.52 × 10⁻³)²

Kc = 0.0184

Find the volume of 56.0 grams of O2
N76 [4]

Answer:

39.2 L at STP

Explanation:

Convert the grams to moles first by dividing 56.0 by the molar mass of O2 (32.0) then convert to volume by multiplying by 22.4.

= 39.2 L

The majority of the elements essential to life are found in what part of the periodic table?
IRINA_888 [86]
The rows in the top third - This group consists of elements like Sodium, Magnesium, Potassium and Calcium on the right and Chlorine, Carbon, Nitrogen and Oxygen on the left.
Sodium and Chlorine are components of salt, a very important compound of our blood, essential for transferring electrical signals from the brain to the rest of the body and vice versa. Calcium is the building block of our bones, while Magnesium and potassium ensure proper functioning of our organs.
