The complete equation representing the synthesis reaction for the formation of ammonia is: 3 H₂ + N₂ ⇒ 2 NH₃

<h3>What is a synthesis reaction?</h3>

It is a reaction in which 2 or more substances combine to form 1 product.

Let's consider the following incomplete synthesis reaction.

3 H₂ + ____ ⇒ 2 NH₃

According to Lavoisier's law, the mass and the elements must be conserved in a chemical reaction. So, since there is nitrogen to the right, the missing element to the left must be nitrogen. Molecular nitrogen is diatomic.

The complete reaction is:

3 H₂ + N₂ ⇒ 2 NH₃

C(s)+ 1 /2 O 2 (g) CO(g) CO(g)+ 1 /2 O 2 (g) CO 2 (g) How will oxygen appear in the final chemical equation?

Hitman42 [59]

Answer : The oxygen will appears in the final chemical equation as a reactant.

Explanation :

The given chemical reactions are:

(1) $C(s)+\frac{1}{2}O_2(g)\rightarrow CO(g)$

(2) $CO(g)+\frac{1}{2}O_2(g)\rightarrow CO_2(g)$

Now we are adding reaction 1 and reaction 2, we get the final chemical equation.

The final chemical equation is:

$C(s)+O_2(g)\rightarrow CO_2(g)$

Thus, the oxygen will appears in the final chemical equation as a reactant.

An electrolytic cell transferred 0.10 m o l of electrons when a constant current of 2.0 A was applied. How many hours did this t

marusya05 [52]

Answer:

1.34 hr

Explanation:

From the question given above, the following data were obtained:

Number of mole of electron (e) = 0.1 mole

Current (I) = 2 A

Time (t) =?

Next, we shall determine the quantity of electricity transferred. This can be obtained as follow:

1 mole of electron = 96500 C

Therefore,

0.1 mole of electron = 0.1 × 96500

0.1 mole of electron = 9650 C

Thus, 9650 C of electricity was transferred.

Next, we shall determine the time. This can be obtained as follow:

Current (I) = 2 A

Quantity of electricity (Q) = 9650 C

Time (t) =?

Q = It

9650 = 2 × t

Divide both side by 2

t = 9650 / 2

t = 4825 s

Finally, we shall convert 4825 s to hour. This can be obtained as follow:

3600 s = 1 hr

Therefore,

4825 s = 4825 s× 1 hr / 3600 s

4825 s = 1.34 hr

Thus, the time taken is 1.34 hr

A student estimated a mass to be 275 g but upon carefully measuring it found the actual mass to be 260 g. what is the percent er

olga2289 [7]

Answer:

5.77% Error.

Explanation:

Given an experimental value of 275 g , and a theoretical value of 260 g, the percent error can be found using the equation:

$\% \: error \: = \frac{ |theoretical \: value \: - \: experimental \: value | }{theoretical \: value} \times 100$

% Error = ( | 260 - 275 | / 260 ) × 100 = ( | - 15 | / 260 ) × 100 = ( 15 / 260 ) × 100 = 1500/260 = 300 / 52 = 5.769230769230.. ≈ 5.77%

algol13

Answer:

Pentane » Hexane » Hexanol

Explanation:

Pentane and Hexane are simple molecular structured with discrete molecules having weak vanderwaals forces of attraction. But Hexane has high molecular mass than pentane hence pentane has lower boiling point than Hexane.

Hexanol has hydrogen bonds between highly electronegative oxygen atom and the hydrogen atom which break on high heat energy application hence it has high boiling point.
