The sample is likely to be from a meteorite.

The reason for this is the fact that the isotope Copper-63 is more abundant on planet Earth than the isotope Copper-65 is. Therefore, if a sample of rock has Cu-65 in a greater quantity, it is likely to be from outer space. Many other elements entered the Earth's crust as a result of meteorite impacts, such as Iron (Fe).

What evidence indicates that nitric acid (HNO3) is a strong acid?​
GREYUIT [131]

Answer:

The presence of hydrogen ions

Explanation:

Nitric acid is formed when hydrogen ions combine with nitrogen oxide ions leading to formation of a strong acid. Wheareas for strong bases the hydroxyl iins must be present, for strong acid, the hydrogen ions contribute to the acidity. Therefore, from the formula of nitric acid, it has hydrogen ions, an indicator of a strong acid.

If you start with 512 grams of aluminum and 1147 grams of copper chloride to make aluminum chloride and copper, what is the limi
Archy [21]

First you need to calculate the number of moles of aluminium and copper chloride.

number of moles = mass / molecular weight

moles of Al = 512 / 27 = 19 moles

moles of CuCl = 1147 / 99 = 11.6 moles

From the reaction you see that:

if        2 moles of Al will react with 3 moles of CuCl

then  19 moles of Al will react with X moles of CuCl

X = (19 × 3) / 2 = 28.5 moles of CuCl, way more that 11.6 moles of CuCl wich is the quantity you have. So the copper chloride is the limiting reagent.
