Answer:
Explanation:
First we look generally at what makes K2SO4.
In one mole of K2SO4, there are 2 moles of the potassium ion (K+) and 1 mole of sulfate ion (SO4 2-).
Knowing that; in 1.75 moles of K2SO4, there must be 2 x 1.75moles of potassium ion (K+) and 1 x 1.75moles of Sulfate ion (SO4 2-)
This gives us 3.5moles of K+ and 1.75moles of SO4 2-
Answer:
Not very, because gold is too heavy to carry many bars at once.
Explanation:
Such movies are far from being accurate.
<em>A standard gold bar weighs about 12.4 kilograms, an equivalence of approximately 27 pounds or 437 ounces, in real life. Hence, a bunch of gold bars would weigh far more than what one person can just lift up, throw, or carry as if it is a bunch of cotton wool. </em>
The correct answer is, therefore, that <u>such movies are far from reality because gold is too heavy to carry many bars at once</u>.
Answer:
1. 6.116x1024 Molecules of H2O
2. 13400 L
3. 8.001x1024 Molecules of Mg3(PO4)2
4. 572 g.
5. 1.017x1025 Molecules of N2
6. 7.24 g
.7. 6980 g. of Al(OH)3
8. 3H2 + N2 => 2NH3
9. S8 + 8O2 => 8SO2
10. Ni(ClO3)2→ NiCl2 + 3O2
11. C2H4 + 3O2→ 2CO2 + 2H2O
12. 2KClO3→ 2KCl + 3O2
13. Cu(OH)2 + 2HC2H3O2→ Cu(C2H3O2)2 + 2H2O
14. C3H8 + 5O2→ 3CO2 + 4H2O
15. 191 g of CO
