Is a minors surface transparent, translucent, or opaque and how do you know

One way to refine iron from iron ore is to heat the ore with hydrogen gas at high temperatures. which change increases the amount of iron produced in the equation fe 3 o 4, solid, plus 4 h 2, gas, plus energy in equilibrium with 3 fe, solid, plus 4

Explain in your own words how volume is measured?

Which balanced equation represents an oxidation-reduction reaction? (1) BaCl2 + Na2SO4==>BaSO4 + 2NaCl (2) C+H2O = = >CO + H2 (3) CaCO3==>CaO + CO2 (4) Mg (OH) 2 + 2HNO3==>Mg (NO3) 2 + 2H2O

Which family correctly represent the elements in group 1 on the periodic table

How many protons electrons and neutrons does the isotope nitrogen 15 have

A covalent chemical bond is one in which outer-shell electrons of two atoms are shared so as to satisfactorily fill the outer electron shells of both atoms. protons and neutrons are shared by two atoms so as to satisfy the requirements of both atoms.

To break a chemical bond, energy must be (1) absorbed (2) destroyed (3) produced (4) released

In an experiment, 132 grams of potassium bromide (KNO3) was dissolved in 100 grams of water at 70 °C in 1 minute.
