Answer:
1:C as all metal are good conductors of heat & electricity
2:D conductivity as it needs delocalized electrons normaly
3:B good conductors of heat & electricity
Answer:
We write 50,000 in scientific notation,
it is written as 5 x 10⁴.
Hope it helps.
For this, you need to know 1) the mass of the hydrate and 2) the mass of the anhydrous salt. Once you have both of these, you will subtract 1) from 2) to find the mass of the water lost.
From the problem, you know that 1) = 2.000 g.
Now you need to find 2). You know that your crucible+anhydrous salt is 5.022 g. To find just the anhydrous salt, subtract the mass of the crucible (3.715 g).
1) = 5.022 g - 3.715 g = 1.307 g
Now you can complete our original task.
Mass H2O = 2) - 1) = 2.000 g - 1.307 g = 0.693 g.
Where are options? without that, i can’t help you sorry
Answer:
Anything that cannot be separated physically or chemically is an element.
