Ok so N2+O2=2NO and my delta h is 180.5 kJ I need to know. If I react 10 g of nitrous gas with excess oxygen how many grams of N

Westkost [7]

Answer:

21.6 grams

Explanation:

N₂ + O₂ → 2NO

First we convert 10 g of N₂ into moles, using its molar mass:

10 g ÷ 28 g/mol = 0.36 mol N₂

Then we convert 0.36 moles of N₂ into moles of NO, using the stoichiometric coefficients of the balanced reaction:

0.36 mol N₂ * $\frac{2molNO}{1molN_2}$ = 0.72 mol NO

Finally we convert 0.72 NO moles into grams, using its molar mass:

0.72 mol NO * 30 g/mol = 21.6 g

What is the value of all conversion factors that are used in dimensional analysis?

Fittoniya [83]

Explanation:

The value of all conversion factors that are used in dimensional analysis must be 1.

Dimensional analysis is a beautiful and systematic way of converting one unit to another using a simple scientific method in which a conversion factor of 1 is used to multiply the number to be converted.

For example, let us convert 1200kg to g:

We know that;

1000g = 1kg

The conversion factor is;

$\frac{1000g}{1kg}$

The above value is the same as 1 since 1kg and 1000g are the same.

Now multiply with 1200kg;

1200kg x $\frac{1000g}{1kg}$ = 1200000g

Which of the following elements has the lowest ionization energy?

larisa86 [58]

Answer:

Explanation:

Ionization energy is defined required energy to eliminate or remove an electron from an ion or atom.

From the given elements Rb or Rubidium has the lowest ionization energy as it has lowest shielding effect, so it easy to remove electron from it's shell.

The ionization energy generally decreases from top to bottom in groups due to lower shielding effect and outer electrons are loosely packed so easy to remove and increases from left to right across a period because of valence shell stability.

Rubidium has atomic number 37 and lies below than other given elements and also placed in the left side in the periodic table.

Hence, the correct option is Rb

What is in the center of an atom? what is this portion of the atom called?

Ludmilka [50]

The Nucleus: The Center of an Atom. The nucleus, that dense central core of the atom, contains both protons and neutrons. Electrons are outside the nucleus in energy levels.
