Nuclear energy is the most important energetic source against the shortage of fossil fuels as oil and methane. Nuclear power are a significant contribution to total electricity production; about 20% in the United states.  It involves the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity within a nuclear power plant

Define molecular formula and empirical formula. What are the similarities and differences between the empirical formula and mole
irga5000 [103]

<u>Explanation:</u>

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.  

In both the formulas, the nature of atoms remains the same but the number differs.

For Example: The molecular formula of oxalic acid is C_2H_2H_4 but the empirical formula of oxalic acid is CHO_2

To calculate the molecular formula, we need to find the valency which is multiplied by each element to get the molecular formula.

The equation used to calculate the valency is:

n=\frac{\text{Molecular mass}}{\text{Empirical mass}}

The empirical mass can be calculated from empirical formula and molar mass must be known.

wlad13 [49]

Answer:

Complex  System

Explanation:

Given that, a descriptive scientific investigation is one of the three main types of investigation which formulates and quantify the natural phenomenon.  This natural phenomenon oftentimes involves Complex System, such as microscopic organisms, thereby, scientists often make observations to understand the interacting parts of this COMPLEX SYSTEM

Hence, the right answer is a COMPLEX SYSTEM

You are given two unknown acids, HX and H2Y, and two values for Ka, 1x10^-7 and 1x10^9. You know that X is a much more electrone
Elena L [17]

Answer:

.

Explanation

In HX , X is more electronegative than Y so HX will ionise more because of  ionic bond between H and X . On the other hand H₂Y will be less polar as compared to HX so it will ionise to a lesser extent . Hence Ka will be more for HX . Ka represents the degree of ionisation of acid . Higher the ionisation , higher is the value of Ka . H₂Y which is less polar will ionise less and hence it will have lesser value of Ka .

Hence H₂Y will have value of 10⁻⁷ and HX will have value of ka equal to 10⁹ .
