A beam of electrons is fired at a crystal of magnesium oxide, and photographic film is used to record the places where the elect

rons come through the crystal. Which of the following changes to the experiment is not likely to change the interference pattern that results on the film?

Answer:

increasing the length of time the beam is fired at the crystal

Explanation:

Interference pattern does not depend on duration of the recording, though this might affect clarity of the image on the photographic film. Other things will change where the electrons end up. Speed of electrons affects its momentum, and thus its position. Proton has different mass, so different interference pattern. A different crystal will create a different interference pattern depending on the molecular formula.

Which statement best describes a chemical reaction?
ziro4ka [17]

Answer:

In a chemical reaction, one or more substances called reactants are combined or  broken down to form products.

Explanation:

Chemical reaction:

In a chemical reaction one or more substance converted into the another substance.

The substances that reacts or combine during the chemical reaction are called reactants while the new species formed as a result of chemical reaction are products.

There are different types of reaction given below:

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

AB → A + B

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

Activation energy Group of answer choices is only required in catabolic reactions that release energy. is not required at all wh
daser333 [38]

Answer:

is used to break reactant bonds and/or make new product bonds.

Explanation:

<em>The correct answer would be that </em><em>activation energy is used to break reactant bonds and/or make new product bonds</em><em>.</em>

The <u>activation energy is the minimum energy that must be overcome by the reactants in a reaction in other to become products</u>. In order for products to be formed, the bonds between reactants must be broken and new ones must be formed to arrive at the products. In other words, the activation energy can be seen as the energy required to break the bonds between reactants and form the bonds between products during the course of a reaction.

<em>Activation energy is required even in the presence of enzymes. The latter only catalyzes reactions by lowering the minimum energy required to break the bonds between reactants and form new ones between products</em>.
