Chem with reference to the "chemistry at work" box on explosives, use bond enthalpies to estimate the enthalpy change for the explosion of 1.00 g of nitroglycerin. i found that the answer is 7.85 kj, but how?

The mass of nitroglycerin is 1 g,

Molar mass of nitroglycerin is 227 g/mol

The number of moles = moles/molar mass

= 1 g / 227 g/mol

= 0.004405 mol

The equation for the bond enthalpy of the reaction is shown below, thus, the total enthalpy change in the reaction is as follows:

ΔHreaction = Number of moles (∑ΔHbond break - ∑ΔH bond forms)

= 0.004405 mol × -3564.5 kJ/mol

= -7.85 kJ

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

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).
