The origin is greek and English
With a mole of skittles placed side by side, you can go around the earth <span>191.17 trillion times.
I hope this helps! If it didn't please reply. Please mark it the brainliest if it did!
</span>(6.022x10^23) x .5" = 3.011x10^23 inches.
<span>3.011x10^23 / 12 in per ft(=.251)
</span><span>.251 /5280 ft per mile = 4.75x10^18 miles
</span><span>4.75x10^18 miles / 24850 mile around the earth = 1.9117x10^14 time around the earth.
</span><span>191.17 trillion times around the earth</span>
Answer:
The only thing that will not affect the potential is the adition of solid Sn.
Explanation:
The potencial of a cell is linked to the concentration of the substances involved in the reactions by the equation of Nernst. So a change of one of them would change the cell potential.
The Keq for this reaction is:
<em>Sn is not included because it's in solid state. </em>
As can be seen, changing the concentrations of H2 (increasing the pressure), H+ (lowering the pH) or Sn2+ will affect the potential.
The only thing that will not affect it is the adition of solid Sn.
Answer:
Barium and Calcium
Explanation:
When heated with chlorine,
Both calcium and barium are able to form ionic bonds.
Hydrogen can only form bonds that are partial positive. It is not strong enough to be considered an ionic bond.
Silicon forms strong covalent with chlorine, called silicon tetrachloride. The structure is in diamond form which requires a lot of heat energy to break the bonds are way more than energy needed to break the bonds between calcium chloride.
Krypton is an inert element which does not form bonds with any elements under standard conditions
