Answer:

The part of Arden's list that seems to be wrong is that genetic engineering can create organisms that survive in different environments (Pro 2).

Explanation:

Genetic engineering is a branch of genetics that introduces the use of technology to modify a living organism by introducing modified DNA into its original genome in order to improve its characteristics

The organisms subjected to changes by genetic engineering are called genetically modified organisms or GMOs, and can be stronger, longer-lived, more productive, or resistant to disease.

<em>Making a species resistant to any environment could cause it to develop in places where it could not live before, affecting the natural balance of an ecosystem to which it previously did not belong, so Pro 2 on Arden's list does not seem to be entirely beneficia</em>l.

Nickel + oxygen = nickel oxide. What is the balanced redox reaction?
uranmaximum [27]

Answer:

This is an oxidation-reduction (redox) reaction:

2 Ni0 - 4 e- → 2 NiII

(oxidation)

2 O0 + 4 e- → 2 O-II

(reduction)

Ni is a reducing agent, O2 is an oxidizing agent.

1) We apply the ideal gas equation:
PV = nRT
n = (21300 x 3/1000) / (8.314 x 323)
n = 0.024
Your answer is correct.

2) Total pressure = Partial pressure of Hydrogen + Partial pressure of water
134.7  = 122.4 + Pw
Pw = 12.3 kPa
Your answer is correct

3) The molar fraction, volume fraction and pressure fraction of gasses are the same thing.
Thus, percentage pressure of Oxygen = 10%
Pressure of Oxygen = 2.04 x 10⁴ x 0.1
= 2.04 x 10³ kPa
Your answer is correct

Well done!

A photon of light has an energy of 1.83 x 10-18). What is the wavelength of this light? Does this light fall in the IR, visible,
Scrat [10]

Answer:

1.09 × 10⁻⁷ m

UV region

Explanation:

Step 1: Given and required data

Energy of the photon of light (E): 1.83 × 10⁻¹⁸ J

Planck's constant (h): 6.63 × 10⁻³⁴ J.s

Speed of light (c): 3.00 × 10⁸ m/s

Step 2: Calculate the wavelength (λ) of this photon of light

We will use the Planck-Einstein's relation.

E = h × c/λ

λ = h × c/E

λ = 6.63 × 10⁻³⁴ J.s × (3.00 × 10⁸ m/s)/1.83 × 10⁻¹⁸ J = 1.09 × 10⁻⁷ m

This wavelenght falls in the UV region of the electromagnetic spectrum.
