Marysya12 [62]3 years ago

Answer:

11.0 L

Explanation:

The equation for this reaction is given as;

2H2  +  O2  -->  2H2O

2 mol of H2 reacts with 1 mol of O2 to form 2 mol of H2O

At STP;

1 mol = 22.4 L

This means;

44.8 L of H2 reacts with 22.4 L of O2 to form 44.8 L of H2O

In this reaction, the limiting reactant is H2 as O2 is in excess.

The relationship between H2 and H2O;

44.8 L = 44.8 L

11.0 L would produce x

Solving for x;

x = 11 * 44.8 / 44.8

x = 11.0 L

12. Complete each of the following word equations for synthesis reactions.
Vlada [557]

Explanation:

12)

a) Sodium + oxygen = ?

When sodium reacts oxygen its forms sodium oxide as a product.

4Na(s)+O_2(g)\rightarrow 2Na_2O(s)

b) magnesium + fluorine = ?

When magnesium reacts with fluorine its forms magnesium fluoride as a product.

Mg(s)+F_2(g)\rightarrow MgF_2(s)

13)

a) 2HgO(s)\overset{\Delta }\rightarrow 2Hg(l)+O_2(g)

Decomposition of mercury(II) oxide on heating gives out mercury and oxygen gas.

b)2H_2O(l)\overset{Electricity}\rightarrow 2H_2(g)+O_2(g)

The electrolytic decomposition of water gives out hydrogen gas amd oxygen gas.

ITS FOR AN EXAM GUYS PLEASE
Anastaziya [24]

Answer: A. Al(s)\rightarrow Al^{3+}(aq)+3e^- and Au^+(aq)+e^-\rightarrow Au(s)

Explanation:

Galvanic cell is a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.

The standard reduction potential for aluminium and gold are as follows:

E^0_{Al^{3+}/Al}=-1.662V

E^0_{Au^{+}/Au}=1.83V

Reduction takes place easily if the standard reduction potential is higher (positive) and oxidation takes place easily if the standard reduction potential is less (more negative).

Here Al undergoes oxidation by loss of electrons, thus act as anode. Gold undergoes reduction by gain of electrons and thus act as cathode.

Anode : Al(s)\rightarrow Al^{3+}(aq)+3e^-

Cathode : Au^+(aq)+e^-\rightarrow Au(s)

Thus magnesium gets oxidized.

These reactions can also be reversed, breaking the large molecules into its individual molecules. what substance would need to b
lesantik [10]
The appropriate response is water. This reversible reaction can be broken into two responses. These two responses are happening all the while, which implies that the reactants are responding to yield the items, as the items are responding to deliver the reactants. Crashes of the responding atoms cause substance responses in a shut framework.

Which of these could be caused by an increase in sunspots activity?
Burka [1]

Answer:

Sun spots are cooler spots on the sun so anything to cool off part of the sun would create a sunspot

What is the percent yield for carbon dioxide if 10.0 grams of carbon
ivolga24 [154]

The percent yield : 81.5%

<h3>Further explanation</h3>

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

2CO+O₂⇒2CO₂

mol CO(MW=28,01 g/mol)

\tt \dfrac{10}{28.01}=0.357

mass CO₂ (theoretical)(MW=44,01 g/mol)

\tt 0.357\times 44.01=15.712~g

the percent yield :

\tt \dfrac{12.81}{15.712}\times 100\%=81.5\%
