How many coulombs of positive charge are there in 1.2 kg of carbon? twelve grams of carbon contain avogadro's number of atoms, with each atom having six protons and six electrons.

5.78 × 10⁷ C

Explanation:

Given that:

The mass of the carbon = 1.2 kg

Also,

1 kg = 1000 g

So, mass = 1200 g

Molar mass of carbon = 12.0107 g/mol

Moles = Mass taken / Molar mass

So,

Moles = 1200 / 12.0107 moles = 99.91 moles

1 mole of carbon contains = 6.022 × 10²³ atoms

Also, 1 atom of carbon contains 6 positive charge (protons)

So,

99.91 moles of carbon contains = 6.022 × 10²³ × 99.91 × 6  protons

Charge on 1 proton = 1.6 × 10⁻¹⁹ C

So,

Charge of 1.2 kg carbon = 6.022 × 10²³ × 99.91 × 6 × 1.6 × 10⁻¹⁹ C = 5.78 × 10⁷ C

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
