igomit [66]

Answer:

6118.11\frac{in}{min}

Explanation:

Hello,

In this case, by knowing that 1 inch equals 2.54 cm and 60 seconds equals 1 min, the resulting value results:

=259\frac{cm}{s}*\frac{1in}{2.54cm}*\frac{60s}{1min}\\   \\=6118.11\frac{in}{min}

Best regards.

How many moles of ammonia (nh3 will be produced from 4.0 moles of nitrogen (n2?
Lana71 [14]
Standard equation would be N2(g)+3H2(g)==>2NH3(g), so through stoichiometry, (4 mol N2)(2mol NH3/1 mol N2), assuming excess H2, would yield 8 moles of NH3.

What mass of potassium chloride, KCl, is produced when 12.6 g of oxygen, 02, is produced?
blagie [28]

Mass of KCl= 19.57 g

<h3>Further explanation</h3>

Given

12.6 g of Oxygen

Required

mass of KCl

Solution

Reaction

2KClO3 ⇒ 2KCl + 3O2

mol O2 :

= mass : MW

= 12.6 : 32 g/mol

= 0.39375

From the equation, mol KCl :

= 2/3 x mol O2

= 2/3 x 0.39375

=0.2625

Mass KCl :

= mol x MW

= 0.2625 x 74,5513 g/mol

= 19.57 g
