D is the answer hope i can help u
Hello.
<span>HI + NaOH --> NaI + H2O
2HClO4 + Sr(OH)2 --> Sr(ClO4)2 + 2H2O
</span>
Have a nice day
Equation#1 - Ca(s)+Cl2(g) ——> CaCl2(s)
Word equation #1- Calcium and Chlorine react to form Calcium Chloride.
Equation #2- N + I3 —-> I3N
Word Equation #2- Nitrogen and Iodine react to form nitrogen triiodine.
Answer:
5.79 × 10^23 Oxygen atoms
Explanation:
Number of Oxygen atom in the compound = 4×3 = 12
Molar mass of Al2(SO4)3 = 342 g/mol.
No of mole = mass/molar mass = 2.74/342 = 8.01×10^-03 mole
2.74g of Al2(SO4)3 × 1 mole of Al2 (SO4)3 / 342g of Al2 (SO4)3 * 12 mole of Oxygen/ 1mole of Al(SO4)3 * 6.02×10^23 Oxygen atom/ 1 mole of Oxygen
= 5.79×10^23 Oxygen atoms
The answer is actually Water Splitting! Hope this works:D
