What is being oxidized?

1 answer:

6 0

An example of something oxidizing is iron turning into iron oxide, or rust. This reaction is very slow, but you know something has iron in it if it rusts. Also, bonus fact, you won't get tetanus if you touch a rusty nail. The rust has to enter the bloodstream for that to happen.

I am a metal which can be drawn into thin wires

Gwar [14]

Answer:

Silver and copper

Explanation:

Siliver

Electrical conductivity=62000000(s/m)

Boiling point=2162

Melting point=961.78

Phase=solid

Copper

Electrical conductivity=59000000(s/m)

Boiling point =2927

Melting point=1084.62

Phase=soild

Metals like gold, silver and copper are drawn into thin wire and are used in an electric circuit because of their high electrical conductivity

Mostly Siliver and copper are used since using gold is much expensive.

what is the relationship between the scale divisions marked on the graduated cylinders and the estimated uncertainty in the volu

AURORKA [14]

Answer:

The relationship between the scale divisions marked on the graduated cylinders and the estimated uncertainty in the volume measurements is that the larger the divisions the larger the uncertainty, and the smaller the divisions the smaller the uncertaintity.

Explanation:

In general, graduated cylinders are marked with divisions (lines) at equal spaces or intervals. There are divisions that show the measure with a number and a series of intermediate not numbered divisions in between two numbered lines.

The uncertainty of the instrument is determined as half the difference between two consecutive marks.

So, the larger the interval of two consecutive marks the larger the uncertainty.

The attached image, taken from brainly.com/question/13102373, shows you some marks in a graduated cylinder.

0.513 mol Al2O3 = g Al2O3

Dovator [93]

Answer:

Molar mass (M) = mass(m) / number of moles (n)

To find the mass of Al2O3 first calculate it's molar mass

thus

M(Al2O3) = (27×2) + (16 × 3)

= 54 + 48

= 102g/mol

Mass of Al2O3 = molar mass × number of moles

= 102 × 0.513

= 52.326g of Al2O3

Hope this helps
