Answer:

Ethical concerns affect scientific research by adding boundaries to what can and cant be experimented on. An example is that its socially unacceptable to experiment on humans because its considered wrong and horrific, even at the expense of learning more about human nature and/or the human body.

Write a balanced equation for the double-replacement neutralization reaction described, using the smallest possible integer coef

g100num [7]

Answer: The balanced chemical equation is given below.

Explanation:

Double-displacement reaction is defined as the reaction in which exchange of ions takes place. The general equation representing this reaction follows:

$AB+CD\rightarrow CB+AD$

The balanced chemical equation for the reaction of barium hydroxide and perchloric acid follows:

$Ba(OH)_2(aq.)+2HClO_4(aq.)\rightarrow Ba(ClO_4)_2(aq.)+2H_2O(l)$

By Stoichiometry of the reaction:

1 mole of barium hydroxide reacts with 2 moles of perchloric acid to produce 1 mole of barium chlorate and 2 moles of water molecule.

Hence, the balanced chemical equation is given above.

PLEASE HELP WILL MARK BRAINLIEST

Zielflug [23.3K]

Answer:

1. There are 7 categories:

Radio waves, microwaves, infrared heat waves, visible light spectrum, ultraviolet waves, x-rays, gamma rays

2. They are all electromagnetic radiation.

3. The amount of energy the photons within them have.

4. The longer the wavelength, the less energy. The shorter the wavelength, the more energy. They are inversely proportional.

5. As the wavelength increases, the smaller the frequency. The shorter the wavelength, the larger the frequency. They are inversely proportional. Also, wavelength is measured in meters and frequency is measured in hertz (cycles per second). They are two of the 3 ways EM radiation is expressed.

6/7 Reds have the least. Violets have the most.

8. Violet has the shortest. Red has the longest.

9. Ultra Violet B-Rays (UV-B) are the harmful rays that cause sunburn.

10. Microwaves are generally used for radar technology.

11/12 You are exposed to all of the categories of the electromagnetic spectrum everyday of every year. You just can't see/feel them all.

hope this helps! stay happy and healthy, friend! :))

WHAT IS THE UNBALCNED EQUATION OF Methane burns in oxygen to produce carbon dioxide and water

deff fn [24]

Answer:

$\boxed{CH_{4}+O_2 --> CO_2 + H_2O}$

Explanation:

<h2>Part 1: Naming compound formulas given the names</h2>

Step 1. Methane's formula is $CH_4$ .

Step 2: Oxygen is a diatomic molecule (it exists bonded to itself for stability purposes), so by itself in chemical equations, it is written as $O_2$ .

Step 3: Carbon dioxide is the molecular compound of one atom of carbon and two atoms of oxygen → $CO_2$ .

Step 4: Water is the common name of the compound of two hydrogen atoms and one oxygen atom → $H_2O$ .

<h2>Part 2: Writing the skeleton equation</h2>

Step 1: Use the determined formulas for the reactants and plug them into the equation. We are told that methane burns in oxygen -- hinting at a combustion reaction. Therefore, we may infer that these are the reactants that yield the products.

Skeleton equations are written with the reactant(s) on the left -- if there are several, they are separated by an addition symbol (+).

With this information, we may begin our equation: $CH_4 + O_2$ , where $CH_4$ is methane and $O_2$ is the diatomic molecule of oxygen.

Step 2: Use the determined formulas for the products and plug them into the equation. We are told that the methane burns in oxygen to produce carbon dioxide and water. Hence, we can separate these two as we did with the reactants.

Now, our products side of the reaction will look like this: $--> CO_2 + H_2O$ , where $CO_2$ is carbon dioxide and $H_2O$ is water.

Step 3: Write the final equation. All you must do after determining both sides of the equation is simply push them together. Place the reactant side of the equation on the left and the product side of the equation on the right.

This gives us our final equation, $\boxed{CH_4 + O_2 --> CO_2 + H_2O}$ .

Because the problem asks for the unbalanced equation, we do not need to take any further steps of balancing the equation.
