Crank

Answer:

A catalytic converter is a device used to reduce the emissions from an internal combustion engine (used in most modern day automobiles and vehicles). Not enough oxygen is available to oxidize the carbon fuel in these engines completely into carbon dioxide and water; thus toxic by-products are produced. Catalytic converters are used in exhaust systems to provide a site for the oxidation and reduction of toxic by-products (like nitrogen oxides, carbon monoxide, and hydrocarbons) of fuel into less hazardous substances such as carbon dioxide, water vapor, and nitrogen gas.

A combustion reaction occurs between one molecule of methane (CHa) and two molecules of oxygen (O2).

SCORPION-xisa [38]

The total number of atoms make up the products :

D) 1 carbon, 4 hydrogen, and 4 oxygen

<h3>Further explanation </h3>

Complete combustion of Hydrocarbons with Oxygen will produce CO₂ and H₂O compounds.

If O₂ is insufficient there will be incomplete combustion produced by CO and H and O

Hydrocarbon combustion reactions (especially alkanes)

For combustion of methane (CH₄) and two molecules of oxygen (O₂).

$\tt CH_4+2O_2\rightarrow CO_2+2H_2O$

The number of atoms make up the products

CO₂ : 1 carbon, 2 oxygen

2H₂O : 4 hydrogen , 2 oxygen

Corn plants and milkweed plants grow in the same area. Over several years, the milkweed plants have taken over the field and the

Katyanochek1 [597]

Answer:

This question is incomplete, the complete part of the question is as follows:

This best demonstrates which type of an interaction between the plants?

A. cooperation

B. parasitism

C. commensalism

D. competition

The answer is D

Explanation:

Organisms in their natural environment interact with one another in so many ways. The ways by which this interaction occurs are; competition, predation, commensalism etc.

Competition is the interaction between two organisms in which one or both organisms are harmed due to limited resources. Competition occurs when the organisms involved occupy the same niche or utilize the same limited resources.

In this question involving corn plants and milkweed plants. They are said to grow in the same area. Over several years, the milkweed plants have taken over the field and the corn plants no longer have space to grow. In this case, there is a limited space for growth, hence, the corn plant and milkweed COMPETE.

Which could describe the motion of an object? Select 3 correct answers. distance = 10 meters and displacement = 1 meter distance

Anit [1.1K]

Answer:

The three correct statements which could describe the motion of an object are:

distance = 10 meters and displacement = 1 meter

distance = 10 meters and displacement = 0

distance = 10 meters and displacement = 10 meters

Explanation:

Motion is the change of position of an object along any path. As such, the path can be rectilinear or along a curve whose direction is variable.

Two important characteristics used to describe a motion are the length of the path traveled and the final distance from the starting point.

The length of the path traveled is what distance describes. The final distance from the starting point to the final point is what displacement describes.

The maginitude of the displacement is the difference between the final position and the starting position.

When the path traveled is rectilinear, the distance and the magnitude of the displacement are the same.

When the path is not rectilinear, the distance (the length of the path) is always greater than the magnitude of the displacement.

Thus, as for the correct statements, you have:

distance = 10 meters and displacement = 1 meter

This means that the object traveled along a 10 meters path, but since it was not rectilinear, the difference between the final position and the starting position is just 1 meter.

distance = 10 meters and displacement = 0

This means that the object traveled 10 meters but it ended back in the very same place from which it departed (a complete turn around a table, for example).

distance = 10 meters and displacement = 10 meters

This means that the travel was in the trip was alogn a straight line, and the object traveled 10 meters and ended 10 meters away from the starting place.

As for the two incorrect statements:

distance = 0 and displacement = 10 meters

distance = 1 meter and displacement = 10 meters

It is not possible that the object ended up 10 meters away from where it was (the displacement), by traveling just 1 meter less than that.
