A. In the complete reaction of 22.99 g of sodium
fenix001 [56]

Answer : 58.44 g

<h3>Further explanation</h3>

The reaction

\tt Na+Cl\Rightarrow NaCl

mole ratio :

Na : Cl : NaCl = 1 : 1 : 1

Molar mass of Na : 22,989769 g/mol = 22.99 g/mol

Molar mass of Cl : 35,453 g/mol= 35.45 g/mol

Molar mass of NaCl : 58,44 g/mol

Let's check the mol for reactant (Na and Cl) and product(NaCl)

  • mol of Na :

\tt mol=\dfrac{22.99}{22.99}=1

  • mol of Cl :

\tt mol=\dfrac{35.45}{35.45}=1

Then the reactants are completed reacting because it matches the mole ratio, which is 1: 1

so that the mole of the product can be determined from the mol Na or Cl, which is 1

  • mass of NaCl :

\tt =\dfrac{mol~NaCl}{mol~Na}\times MW~NaCl\\\\=\dfrac{1}{1}\times 58.44\\\\=\boxed{\bold{58.44~g}}

GeF 3H is formed from GeH 4 and GeF 4 in the combination reaction: GeH 4 3GeF 4 4GeF 3H If the reaction yield is 92.6%, how many
Olin [163]

Answer:

6.48

Explanation:

GeH4 + 3 GeF4 > 4 GeF3H

3 moles of GeF4 react to form 4 moles of GeF4

Therefore, (8 x 3/4)/0.926

= 6.48 moles

If energy cannot be created or destroyed, what happens to the kinetic and potential energy?​
Julli [10]

Answer:

According to the law of conservation of energy, energy cannot be created or destroyed, although it can be changed from one form to another. KE + PE = constant. ... As the car coasts down the hill, it moves faster and so it's kinetic energy increases and it's potential energy decreases. hope this helps
