Hydrogen is a possible future fuel. However, elemental hydrogen is rare, so it must be obtained from a hydrogen- containing comp
dimulka [17.4K]

Answer:

1.1 × 10² g

Explanation:

First, we will convert 1.0 L to cubic centimeters.

1.0 L × (10³ mL/1 L) × (1 cm³/ 1 mL) = 1.0 × 10³ cm³

The density of water is 1.0 g/cm³. The mass corresponding to 1.0 × 10³ cm³ is:

1.0 × 10³ cm³ × (1.0 g/cm³) = 1.0 × 10³ g

1 mole of water (H₂O) has a mass of 18 g, consisting of 2 g of H and 16 g of O. The mass of Hydrogen in 1.0 × 10³ g of water is:

1.0 × 10³ g H₂O × (2 g H/18 g H₂O) = 1.1 × 10² g

Write a net ionic equation for the reaction that occurs when aqueous solutions of nitric acid and sodium hydroxide are combined.
Veronika [31]

Answer:

H^+(aq) +  OH^-(aq) -------> H2O(l)

Explanation:

We must first write the molecular reaction equation as follows;

HNO3(aq) + NaOH(aq) ------>NaNO3(aq) + H2O(l)

The complete ionic equation is;

H^+(aq) + NO3^-(aq) + Na^+(aq) + OH^-(aq) -------> Na^+(aq) + NO3^-(aq) + H2O(l)

The net ionic equation therefore is;

H^+(aq) +  OH^-(aq) -------> H2O(l)
