Answer:

Explanation:

Protons have a positive net charge,

Neutrons being neutral don't have a net charge.

Each proton is one extra net charge if you have 16 of them and the neutrons don't affect your net charge you will have 16.

Answer:

2H₂ + O₂ → 2H₂O

Explanation:

Chemical equation:

H₂ + O₂ → H₂O

Balance chemical equation:

2H₂ + O₂ → 2H₂O

Step 1:

H₂ + O₂ → H₂O

Left hand side Right hand side

H = 2 H = 2

O = 2 O = 1

Step 2:

H₂ + O₂ → 2H₂O

Left hand side Right hand side

H = 2 H = 4

O = 2 O = 2

Step 3:

2H₂ + O₂ → 2H₂O

Left hand side Right hand side

H = 4 H = 4

O = 2 O = 2

Determine how many grams of N2 are produced from the reaction of 8.37 g of H2O2 and 5.29 g of N2H4.

Dmitriy789 [7]

N₂H₄ + 2H₂O₂    → N₂ + 4H₂O

mol = mass ÷ molar mass

If mass of hydrazine (N₂H₄) = 5.29 g
then mol of hydrazine = 5.29 g ÷ ((14 ×2) + (1 × 4))
  = 0.165 mol

mole ratio of hydrazine to Nitogen is 1 : 1
  ∴ if moles of hydrazine = 0.165 mol
then moles of nitrogen = 0.165 mol

Mass = mol × molar mass

Since mol of nitrogen (N₂) = 0.165
then mass of hydrazine    = 0.165 × (14 × 2)
   = 4.62 g

Using the following equation 5KNO2+2KMnO4+3H2SO4=5KNO3+2MnSO4+K2SO4+3H20. Starting with 2.47 grams of KNO2 and excess KMnO4 how

Aleonysh [2.5K]

Given equation : $5KNO_{2} + 2KMnO_{4} + 3H_{2}SO_{4}\rightarrow 5KNO_{3} + 2MnSO_{4} + K_{2}SO_{4} + 3H_{2}O$

Given information = 2.47 grams KNO2 and excess KMnO4 and we need to find grams of water (H2O).

Since KMnO4 is in excess, so grams of water(H2O) can be calculated using grams of KNO2 with the help of stoichiometry.

To find grams of water(H2O) from grams of KNO2 , we need to follow three steps.

Step 1. Convert 2.47 grams of KNO2 to moles of KNO2.

$Moles = \frac{grams}{molar mass}$

Molar mass of KNO2 = 85.10 g/mol

$Moles = 2.47 gram KNO2\times \frac{1 mol KNO2}{85.10 gram KNO2}$

Moles = 0.0290 mol KNO2

Step 2. Convert moles of KNO2 to moles of H2O using mole ratio.

Mole ratio are the coefficient present in front of the compound in the balanced equation.

Mole ratio of KNO2 : H2O is 5 : 3 (5 coefficient of KNO2 and 3 coefficient of H2O)

$0.0290 mol KNO2\times \frac{3 mol H2O}{5 mol KNO2}$

Mole = 0.0174 mol H2O

Step 3. Convert mole of H2O to grams of H2O

Grams = Moles X molar mass

Molar mass of H2O = 18.00 g/mol

$Grams = 0.0174 mol H2O\times \frac{18 g H2O}{1 mol H2O}$

Grams of water = 0.313 grams H2O

Summary : The above three steps can also be done in a singe setup as shown below.

$2.47 gram KNO2\times \frac{(1 mol KNO2)}{(85.10 gram KNO2)}\times \frac{(3 mol H2O)}{(5 mol KNO2)}\times \frac{(18.00 gram H2O)}{(1mol H2O)}$

In the above setup similar units get cancelled out and we will get grams of H2O as 0.313 grams water (H2O)
