A scientist is conducting an investigation that involves water, silver, carbon dioxide, and oxygen gas. Which group of statement

ivanzaharov [21]

Correct answer choice is:

<h2>D. They are each made of matter. Some are compounds made of one type of element. Some are pure atoms.</h2><h3>Explanation:</h3>

The matter is a substance that has inertia and holds bodily area. According to advanced physics, matter consists of several kinds of particles, each with volume and area.

A pure element indicates a substance whose atoms possess the equivalent atomic number or number of protons.

Silver is extensively utilized as a manufacturing catalyst for the composition of ethylene epoxide via ethylene oxidation and for formaldehyde via methanol oxidation. Oxygen classes on silver are determined to perform a pivotal use in ethylene epoxidation and particular methanol oxidation.

The outcome of the reaction between hydrogen gas and oxygen gas is water vapor (gas).

Water and carbon dioxide are compounds composed of various elements, whereas, silver and oxygen remain pure elements.

Ierofanga [76]

Answer:

A secondary pollutant

Explanation:

Pollutants can broadly be classified into two main categories based on their formation or synthesis. 1: Primary pollutants, 2: Secondary pollutants.

1: Primary pollutants

Primary pollutant can be considered as any environmental pollutant that is being directly emitted from a certain source like when we burn coal carbon di oxide is directly emitted into the atmosphere so CO2 is a primary pollutant.

Similarly sulfur di oxide or SO2 is also a primary pollutant that is emitted by the gas emissions of motor vehicles.

2: Secondary pollutants:

On the other hand, secondary pollutant is something that is not directly emitted on earth as an environmental pollutant but some how it is formed due to a reaction of primary pollutant.

Such as mentioned in the question that SO2 when oxidized in air in the presence of enzymes and water, it form H2SO4 or acid rain which directly falls on earth and incurs great amount of damage to not only living organisms but also non-living organisms such as marble buildings.

Therefore, acid rain is secondary pollutant. Please see picture for better understanding.

Hope it help!

Nuclear power plants create _____ pollution.

EleoNora [17]

The correct answer is option C

The demand for a better life increased the pollution in the society. The increased pollution in the environment led to many health problems.

The Nuclear power plant creates radioactivity and thermal pollution.

The water used in the nuclear power plants is very warm and causes thermal pollution as it is released into water bodies.

The nuclear power plant uses radioactive substances like uranium and the waste that is left is radioactive waste.

Why is it important to know the division or phylum of the various plant species growing in your backyard?

Alex17521 [72]

It is important to know the division or phylum of the various plant species growing in your backyard so as to determine whether they will spread and ruin other crops and plants of yours. Not every plant is beneficial, so you need to know which ones to keep, and which to deplant.
