Read the following chemical equation. Mg(s) + H+ Cl− → Mg2+ Cl− + H2 What most likely happens during this reaction?

spin [16.1K]

Answer:

Magnesium loses two electrons.

Explanation:

As clear from the reaction Mg converted from Mg(s) to Mg²⁺, so Mg converted from the oxidation state (0) to (2+).

∴ Mg losses two electrons.

Cl⁻ remains as it is, so it is considered as a catalyst and neither loss nor gain any electrons.

So, the correct choice is Magnesium loses two electrons.

Nitrogen and hydrogen combine at a high temperature, in the presence of a catalyst, to produce ammonia. N 2 ( g ) + 3 H 2 ( g )

Kisachek [45]

Answer:

After complete reaction, 0.280 moles of ammonia are produced

Explanation:

Step 1: Data given

Number of moles N2 = 0.140 moles

Number of moles H2 = 0.434 moles

Step 2: The balanced equation

N2(g) + 3H2 (g) ⟶ 2NH3 (g)

Step 3: Calculate the limiting reactant

For 1 mol N2 we need 3 moles H2 to produce 2 moles NH3

N2 is the limiting reactant. It will completely be consumed (0.140 moles).

H2 is in excess. There will react 3*0.140 = 0.420 moles

There will remain 0.434 - 0.420 = 0.014 moles

Step 4: Calculate moles NH3

For 0.140 moles N2 we'll have 2*0.140 = 0.280 moles NH3

After complete reaction, 0.280 moles of ammonia are produced

Which of the two forces is greater the force on the firefly or the force on the bus explain your answer please I really need hel

maksim [4K]

Answer: The force on the firefly

The unfortunate firefly hitting the bus does not change the velocity of the bus very much. Technically there is a change, but it's so very small and miniscule that it barely registers. To any casual observer not paying very close attention, they don't notice anything at all. So effectively the force on the firefly is a lot greater since the firefly got the worst end of the deal.

So in short, we look at the velocity of each object and see which velocity changed the most. In this case, the firefly's velocity changed from whatever speed it was flying to 0 when it stops flying all together. That's why the force is greater on the bug.

How many grams of KCN are in 10.0 ml of a 0.10 M solution?

attashe74 [19]

Explanation:

As it is known that molarity is the number of moles present in a liter of solution.

Mathematically, Molarity = $\frac{no. of moles}{Volume in liter}$
