All the processes that form mountain ranges are known as orogenesis. It is a process where a section of the Earth's lithosphere folds and deforms by compression forming mountain ranges this is due to movements of the tectonic plates. The forces or events that acts to this process are called oregony.

A 10L gas container is designed to hold gasses with a pressure of up to 5000mmHg. If a gas sample that has a pressure of 600mmHg
Morgarella [4.7K]

Explanation:

First, let's review the ideal gas law, PV = nRT. In this equation, 'P' is the pressure in atmospheres, 'V' is the volume in liters, 'n' is the number of particles in moles, 'T' is the temperature in Kelvin and 'R' is the ideal gas constant (0.0821 liter atmospheres per moles Kelvin).

First ionization energy
Andru [333]

Answer:

The first ionization energy is defined as

  • Energy which is required to pull out one mole of the outermost shell's electrons in a neutral atom from one mole of gaseous atoms to produce 1 mole of gaseous ions each with a charge of 1+.
  • A\to A^++ e^{-} , where A is any neutral atom.
  • In the periodic table, Its value decreases from top to bottom in groups and increases from left to right across a particular period.
  • Helium has the largest first ionization energy.
  • Francium has one of the lowest.

You are given a sample of limestone, which is mostly CaCO3, to determine the mass percentage of Ca in the rock. You dissolve the
irakobra [83]

Answer:

34.15% is the mass percentage of calcium in the limestone.

Explanation:

Mass of precipitate that is calcium oxalate = 140.2 mg = 0.1402 g

1 mg = 0.001 g

Moles of calcium oxalate = \frac{0.1402 g}{128 g/mol}=0.001095 mol

1 mole of calcium oxalate have 1 mole of calcium atom.

Then 0.001095 moles of calcium oxalate will have 0.001095 moles of calcium atom.

Mass of 0.001095 moles of calcium :

0.001095 mol × 40 g/mol = 0.04381 g

Mass of sample of limestone = 128.3 mg = 0.1283 g

Percentage of calcium in limestone:

\frac{0.04381 g}{0.1283 g}\times 100=34.15\%

34.15% is the mass percentage of calcium in the limestone.
