Do metals donate or accept electrons? what do they become after they donate/accept electrons?

1 answer:

8 0

Metal usually donates electrons. The concept behind this phenomenon is stability. The elements with the most stable electronic configuration are the noble gases in Group 5A. As a result, the other elements donate or accept electrons so that they would be like the noble gases. Since metals are past their nearest noble gas element, they have to shed their electrons. When they do, they become cations which are positively charged ions.

2 C₁₇H₁₉NO₃ + H₂SO₄ → Product
Moles of H₂SO₄ = M x V(liters) = 0.0116 x 8.91/1000 = 1.033 x 10⁻⁴ mole
moles of morphine = 2 x moles of H₂SO₄ = 2.066 x 10⁻⁴
Mass of morphine = moles x molar mass of morphine = 2.066 x 10⁻⁴ x 285.34
= 0.059 g
percent morphine = $\frac{mass of morphine}{mass of opium} x 100$
= $\frac{0.059}{0.685} x 100$ = 8.6 %

Write sulfur dioxide reactions

scZoUnD [109]

Answer:

Sulfur dioxide is a covalent bond because we have two non-metals (Sulfur and Oxygen).

$S + O_{2} \to SO_{2}$ (<em>Sulfur dioxide formula)</em>

It's called Sulfur dioxide but it can be called Sulfurous anhydride and Sulfur (lV) oxide.

Sulfur dioxide can have different reactions:

In the presence of oxygen oxidation of sulfur dioxide to sulfur trioxide occurs and the formula is:

$SO_{2}+\frac{1}{2} O_{2}= SO3$

The equal is because it's a reversible equation. This reaction is spontaneous.

The sulfur trioxide reacting with water produces sulfuric acid. The formula is:

$3 SO_{2} + O_{3} \to 3 SO_{3}\\SO_{3} + H_{2}O \to H_{2}SO_{4}$

Also the sulfur dioxide reacting with sodium hydroxide produces sodium sulfite and the formula is:

$SO_{2} + 2 NaOH \to Na_{2}SO_{3} + H_{2}O$

And finally we have the reduction of sulfur dioxide (it can be in presence of hydrogen sulfide) getting elemental sulfur and water. The formula is:

$SO_{2} + 2 H_{2}S \to 3 S + 2 H_{2}O$

heated blocks of iron used to be warm bed. A 1600g brick of iron heated to 155c would release how many joules of heat energy as

omeli [17]

We are going to use this formula :

Q = M*C*ΔT

when Q is the heat released by the material in J

and M is the mass in gram = 1600 g

C is the specific heat capacity of iron = 0.4494 J/g

and ΔT is the changing in temperature = 155 - 25 = 130 °C

So by substitution:

∴ Q = 1600 g * 0.4494 J/g * 130 °C

= 93475 J

∴ The amount of heat released in Joule = 93475 J
