allsm [11]

Answer:

This is an example of scientific investigation being led by inductive reasoning.

Explanation:

Inductive reasoning is the type of reasoning used to make broad generalizations from specific observations. We have certain pieces of data and make conclusions based on them. In the given example, astronomers have made a specific observation - that the orbit of Uranus isn't uniform. Based on that fact, they made a broader conclusion - that there is another planet. There are probably more things that could lead to the same conclusion.

The opposite is deductive reasoning, where a person starts off with a broad generalization and tries to make specific, logical conclusions based on it.

For the reaction VCl2 + Cl2 → VCl5, what are the reactants, products, and correct coefficients in the balanced equation?
mafiozo [28]

Answer is: Reactants: 2VCl2 and 3Cl2; product: 2VCl5.

Balanced chemical reaction: 2VCl₂ + 3Cl₂ → 2VCl₅.

According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.

There are ten chlorine atoms and two vanadium atoms on both side of balanced chemical reaction.

Determine the end (final) value of n in a hydrogen atom transition, if the electron starts in and the atom emits a photon of lig
Usimov [2.4K]

Complete Question

Determine the end (final) value of n in a hydrogen atom transition, if the electron starts in n=4 and the atom emits a photon of light with a wavelength of 486 nm. Group of answer choices

Answer:

n=2

Explanation:

From the question we are told that:

Wavelength \lambda=486nm=>486*10^{-9}

Generally the equation for Atom Transition is mathematically given by

\frac{1}{\lambda}=R_{\infty }(\frac{1}{n_1^2}-\frac{1}{n_2^2})

Where

Rydberg constant R_{\infty}=1.097*10^7

Therefore

\frac{1}{486*10^{-9}}=1.097*10^7*(\frac{1}{n_1^2}-\frac{1}{4^2})

(\frac{1}{n_1^2}-\frac{1}{4^2})=\frac{1}{486*10^{-9}*1.097*10^7}

n_1^2=3.98

n=1.99

n=2
