metal- a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity
non-metals- an element or substance that is not a metal.
metaloids- an element properties are intermediate between those of metals and solid nonmetals or semiconductors.
substance- a particular kind of matter with uniform properties.
physical properties- any property that is measurable, whose value describes a state of a physical system
luster- a gentle sheen or soft glow, especially that of a partly reflective surface.
conductivity- the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field that causes the flow of current. It is the reciprocal of the resistivity.
Answer:
Explanation:
So 1 mole of NaCl weighs 58.5g. So now we need to convert grams into moles by dividing mass in grams by the mass of 1 mole. This means that in 1dm3 of solution there must be 1 mole of sodium ions. The number of particles in 1 mole is given by the Avogadro Constant which is equal to 6.02x1023mol−1
Answer: 0.923 L
Explanation: The reaction between naoh and h3po4 is:
3naoh + h3po4 —> na3po4 + 3h20
this means it requires 3 mols of naoh to make na3po4
given the concentration, 3.25 M, the equation looks like this:
3.0 mol x (1.0L/ 3.25mol) = 0.923 L
