If 3.0 g of NH3 reacts with 5.0 g of HCl, what is the limiting reactant?
ELEN [110]
<h2>Answer:HCl</h2>

Explanation:

\text{number of moles}=\frac{\text{given mass}}{\text{molar mass}}

For NH_{3},

\text{given mass}=3g

\text{molar mass}=14+3=17g

n_{NH_{3}}=\frac{3}{17}=0.176

For HCl,

\text{given mass}=5g

\text{molar mass}=1+35.5=36.5g

n_{HCl}=\frac{5}{36.5}=0.136

The reaction between NH_{3} and HCl is

NH_{3}+HCl→NH_{4}Cl

So,one mole of NH_{3} requires one mole of HCl

0.176 moles of NH_{3} requires 0.176 moles of HCl

But there are only 0.136 moles of HCl available.

HCl will be consumed first.

So,HCl is the limiting reagent.

How many oxygen atoms are there in 582 grams of caffeine (CH10N402, 194 g/mol)? Avogadro's Number: 1 mole = 6.02 x 1023 species
Sergeu [11.5K]

Answer:

3.61 * 10 ²⁴atoms.

Explanation:

Moles is denoted by given mass divided by the molecular mass ,

Hence ,

n = w / m

n = moles ,

w = given mass ,

m = molecular mass .

From the question ,

w = 582 g

m = 194 g/mol

The number of moles can be calculated from the above formula , and substituting the respective values ,

n = w / m  = 582 g / 194 g/mol  =  3 mol

In the molecular formula of caffeine ,

<u>In 1 mole of caffeine their are - 2 moles of Oxygen. </u>

Therefore , in  3 moles of Caffeine there will be 6 moles of oxygen.

As well know ,

one mole of any substance contains 6.023*10²³ atoms,

Therefore , in  6 mol of oxygen =  6 * 6.023*10²³ atoms  = 3.61 * 10 ²⁴atoms.

What principal quantum number refers to:
docker41 [41]
The principle quantum number "n" represents the relative overall energy of each orbital, and the energy of each orbital increases as the distance from the nucleus increases. The sets of orbitals with the same "n" value are often referred to as electron shells or energy levels.

nalin [4]

Answer:

Verdadero (True).

Explanation:

Después de la desintegración del citado virreinato, los nuevos Estados intentaron establecer sus fronteras, a menudo a través de guerras e invasiones. Cabe destacar la invasión brasileña de Uruguay o la Guerra de la Triple Alianza. En menor medida, lo hicieron a través de tratados internacionales. (After the disolution of the viceroyalship described above, the new States attempted to establish their frontier usually by wars and invasions. It is to highlight the Brazilian invasion of Uruguay or the Triple Alliance' War. In a lesser extent, they made it through international treaties.)
