What is the empirical formula for Hg2(NO3)2

den301095 [7]

Answer: HgNO₃


Explanation:


The empirical formula is the formula that shows the ratio of the atoms in its simplest form, this is using the smallest whole numbers.


The empirical formula may or may not be the same molecular formula.


In this case you are given the molecular formula Hg₂(NO₃)₂. Since, the ratio of the atoms of Hg, N, and O is 2: 2: 6, respectively, the same ratio is expressed if you divide by the greatest common factor (GCF).


The GCF of 2, 2, and 6 is 2. So, the ratios can be simplified to 1:1:3, meaning 1 mol of Hg, 1 mol of N, and 3 mol of O or HgNO₃.

¿Qué volumen ocuparán 12 g de hierro?

sasho [114]

Answer:

$\large\boxed{\large\boxed{volume=1.5cm^3}}$

Explanation:

Translation:

What volume will 12g of iron occupy?

<h2>Solution</h2>

Iron is a solid substance at room temperature. You can find the volume of solids (and of not solids) using the density.

$Density=\dfrac{mass}{volume}$

You can obtaindthe density of most pure substances in the internet. The density of iron at room temperature is 7.874 g/cm³.

Thus, substituting in the formula, you get:

$7.874g/cm^3=\dfrac{12g}{volume}\\ \\ \\ volume=\dfrac{12g}{7.874g/cm^3}\\ \\ \\ volume=1.5cm^3$

The answer is rounded to two significant figures because the input, 12g, has two significant figures.

Using standard heats of formation, calculate the standard enthalpy change for the following reaction. 2NH3(g) 3N2O(g)4N2(g) 3H2O

trasher [3.6K]

Answer: $\Delta H^{0} = -879.15 kJ/mol$

Explanation: Heats of formation is the amount of heat necessary to create 1 mol of a compound from its molecular constituents. The basic conditions the substance is formed is at standard conditions: 1 atm and 25°C. Each compound has its own heat of formation per mol of compound (kJ/mol), but to an element is assigned a value of zero.

Standard Enthalpy Change is defined as the heat absorbed or released when a reaction takes place. It can be positive or negative, which means reaction is endothermic or exothermic, respectively.

Enthalpy change is calculated as the difference between the sum of heat formation of products and the sum of heat formation of the reactants:

$\Delta H^{0}=\Sigma H^{0}_{f}_{(products)}-\Sigma H^{0}_{f}_{(reactants)}$
