Answer:

The volume of ammonia produced by 4.2 L of hydrogen and excess nitrogen is 2.8 L.

Explanation:

Given data:

Volume of H₂ = 4.2 L

Volume of NH₃ produced = ?

Solution:

First of all we will write the balance chemical equation:

N₂ + 3H₂    →   2NH₃

Hydrogen is limiting reactant and volume ratio is,

                         H₂           :       NH₃

                         3             :         2

                         4.2         :           2/3 × 4.2 =  2.8 L

The volume of ammonia produced by 4.2 L of hydrogen and excess nitrogen is 2.8 L.

Answer:

30 hot dogs

Explanation:

It is given that :

There are 4 packets of eight wieners, i.e. 4 x 8 = 32 wieners

There are 3 bags of ten buns, i.e. 3 x 10 = 30 buns

One hot dogs need 1 bun and 1 wiener to make a hot dog.

There are 30 buns, so 30 hot dogs can be made out by using all the 30 buns and the 30 wieners out of the 32 wieners.

Therefore, 30 hot dogs.

And the number of extra wieners left = 32 - 30 = 2 wieners.

BRAINLIESTTT ASAP!! PLEASE HELP ME :)

Answer : False, there will be two lithium and one oxygen atoms in a unit molecular structure of lithium oxide.

Explanation:

Electronic configuration of lithium is :

Li=1s^2s^1

In order to attain stable electronic configuration it will loose an electron and form positively charge cation.

Li^+=1s^22s^0

The electronic configuration of oxygen is:

O=1s^22s^22p^4

Oxygen being second most electronegative atom requires two electrons to attain noble gas configuration stability and form negatively charge ion with 2- charge.:

O^{2-}=1s^22s^22p^6

When two atom of lithium and oxygen comes together , one electron from each lithium atom get transferred to an oxygen atom which results in formation of lithium oxide.

2Li^++O^{2-}\rightarrow Li_2O

3. How many atoms are found in 5.20 g of magnesium (Mg)?
Ganezh [65]

Explanation:

In order to go from mass of magnesium to atoms of magnesium, we have to do two things:

   Convert mass of Mg to moles of Mg using the molar mass of Mg as a conversion factor

   Convert moles of Mg to atoms of Mg using Avogadro's number (6.02×1023) as a conversion factor

Step 1:

Before we start, I should note that the molar mass of Mg is 24.31gmol. We can go from mass to moles using dimensional analysis. The key to dimensional analysis is understanding that the units that you don't need any more cancel out, leaving the units that are desired:

48.60g

×1mol24.31g

=2.00mol

Step 2:

We'll use this relationship:

www.sprinklernewz.uswww.sprinklernewz.us

Using the moles of Mg that we just obtained, we can use Avogrado's number to perform dimensional analysis in order to cancel out units of mol to end up with atoms of Mg:

2.00mol

×6.02×1023atoms1mol

=1.204×1024atoms

Thus, 48.60g of Mg is equivalent to 1.204×1024atoms

Hope this helped :)
