Does the following equation follow the law of conservation of mass? Show your work

Soloha48 [4]

Answer:

No.

Explanation:

If the equation follows the law of conservation of mass, then the amount of reactants must be equal to the amount of products. That is not the case for the provided equation due to 1 Ag on the reactants side versus 2 Ag on the products side.

2H2 + O2 → 2H2O<br><br> Given 1.0 moles of O2, how many grams of H2O can be produced ?

Ivenika [448]

Answer:

2H2O2 --> O2 + 2H2O

It is decomposition of hydrogen peroxide into oxygen.

It can also be described a reaction showing how H2O2 acts as a reducing agent

H2O2(aq) ---------> O2(g) + 2H^+ (aq) + 2e E = + 1.77 V

2h2 O2 2h2o

Ammonia, nh3, for fertilizer is made by causing hydrogen and nitrogen to react at high temperature and pressure. How many moles

charle [14.2K]

Answer:

$0.30molNH_3$

Explanation:

Hello there!

In this case, since the reaction for the formation of ammonia is:

$3H_2+N_2\rightarrow 2NH_3$

We can evidence the 1:2 mole ratio of nitrogen gas to ammonia; therefore, the appropriate stoichiometric setup for the calculation of the moles of the latter turns out to be:

$0.15molN_2*\frac{2molNH_3}{1molN_2}$
