Answer:
No
Explanation:
The Earth would not have seasons if there is no revolution because the temperatures would not change.
Answer:
pH = 13.1
Explanation:
Hello there!
In this case, according to the given information, we can set up the following equation:
Thus, since there is 1:1 mole ratio of HCl to KOH, we can find the reacting moles as follows:
Thus, since there are less moles of HCl, we calculate the remaining moles of KOH as follows:
And the resulting concentration of KOH and OH ions as this is a strong base:
![[KOH]=[OH^-]=\frac{0.00576mol}{0.012L+0.032L}=0.131M](https://tex.z-dn.net/?f=%5BKOH%5D%3D%5BOH%5E-%5D%3D%5Cfrac%7B0.00576mol%7D%7B0.012L%2B0.032L%7D%3D0.131M)
And the resulting pH is:

Answer:
Explanation:
2 mole x 6.023x 10^23atoms/mole =12.04 atoms
By multiplying the total amount in grams of a given food sample by energy values established by nutritionists for the particular food type i believe
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. Calculations are as follows:
</span>2.50 mol FeWO4 ( 1 mol Fe / 1 mol FeWO4 ) ( <span>6.022 x 10^23 atoms Fe / 1 mol Fe )</span>= 1.51 x 10^24 atoms Fe
