Answer:

The answer is: Carbon fixation

Explanation:

Carbon fixation is a natural process by which <u>carbon atom of the carbon dioxide molecule is included in an organic molecule</u> such as carbohydrate.

<u>Example of carbon fixation</u>: Photosynthesis

Photosynthesis is a natural process in which carbohydrates and oxygen are produced from carbon dioxide and water in the presence of sunlight.

In this process, <u>light energy from the sun is utilized to convert carbon dioxide (CO₂) to sugar such as glucose</u> (C₆H₁₂O₆). Therefore, it is an example of carbon fixation.

<em>The reaction involved is:</em>

$6 CO_{2} + 6H_{2}O \overset{light}{\rightarrow} C_{6}H_{12}O_{6} + 6O_{2}$

(a) The temperature goes up by 3⁰C.

(b) There is increase in temperature, so the reaction is exothermic.

(d) Examples of endothermic reaction include, melting solid salts and evaporating liquid water.

<h3>What is exothermic reaction?</h3>

Exothermic reaction is a type of chemical reaction in which energy is transferred to or from the surroundings.

Examples of exothermic reactions include the following;

Rusting of Iron
Burning of Coal
Reaction of Strong Acid and Water
Water and Calcium Chloride

<h3>What is endothermic reaction?</h3>

Endothermic reaction is a type of chemical reaction in which energy is absorbed from the surroundings.

Examples of endothermic reactions include the following;

Melting solid salts.
Evaporating liquid water, etc

<h3>Change in temperature</h3>

From the increase in temperature from 15⁰C to 23⁰C, we can conclude that the temperature goes up by 3⁰C.

20⁰C - 17⁰C = 23⁰ - 20⁰C = 3⁰C.

Since there is increase in temperature, the reaction is exothermic.

Earth's atmosphere blocks short wavelengths of the electromagnetic spectrum. Which telescopes must be places in orbit around Ear

Ostrovityanka [42]

Answer: gamma-ray telescopes

Explanation:

this is the answer because the question is asking what telescope must be

placed to observe SHORT-WAVELENGTH radiation. Gamma-rays have very short wave-lengths so therefore it would be gamma-ray telescopes. visible, infrared, and radio all have long wave-lengths, so we can instantly eliminate them.

Suppose a current of flows through a copper wire for seconds. Calculate how many moles of electrons travel through the wire. Be

vagabundo [1.1K]

Answer:

1.20 × 10⁻³ mol e⁻

Explanation:

There is some info missing. I think this is the original question.

<em>Suppose a current of 0.880 A flows through a copper wire for 132 seconds. Calculate how many moles of electrons travel through the wire. Be sure your answer has the correct unit symbol and round your answer to significant digits.</em>

<em />

Step 1: Given data

Intensity of the current (I): 0.880 A (= 0.880 C/s)

Time elapsed (t): 132 s

Step 2: Calculate the charge, in Coulomb, that travel through the wire

We will find the circulating charge (q) using the following expression.

$q = I \times t = \frac{0.880C}{s} \times 132s = 116C$

Step 3: Calculate the moles of electrons with a charge of 116 C

We will use the relationship 1 mole of electrons = 96,486 C (<em>Faraday's constant</em>)

$116C \times \frac{1mol\ e^{-} }{96,486 C} =1.20 \times 10^{-3} mol\ e^{-}$
