Answer:
This metal could be the aluminium with a specific heat of
Explanation:
A pie of unknown metal presents a mass (M) of 348 g. This metal is heated using energy (E) of 6.64 kJ and the temperature increases from T1 =24.4 to T2 =43.6°C. We can calculate the specific heat (H) of this metal as follows
We can replace previously presented data in this equation. After simplifying and converting to adequated units, we found that
Finally, the specific heat of this metal is
The aluminium could be the metal, its specific heat is similar to that found in this problem.
Finally, we can conclude that this metal could be the aluminium with a specific heat of
<u>Answer:</u> The number of moles of strontium bicarbonate is
<u>Explanation:</u>
Formula units are defined as lowest whole number ratio of ions in an ionic compound. It is calculate by multiplying the number of moles by Avogadro's number which is
We are given:
Number of formula units of
As, number of formula units are contained in 1 mole of a substance.
So, number of formula units will be contained in =
of strontium bicarbonate.
Hence, the number of moles of strontium bicarbonate is
