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

Answer:
The solubility of gases in liquids decreases with increasing temperature. Conversely, adding heat to the solution provides thermal energy that overcomes the attractive forces between the gas and the solvent molecules, thereby decreasing the solubility of the gas; pushes the reaction in Equation 4 to the left
Given that Ka = 4.3 × 10^-4
At the half equivalence (Stoichiometric) point;
pH = pKa = - log (Ka)
Therefore; pKa = - log (4.3 ×10^-4)
= 3.37
Therefore; the pH at the half-stoichiometric point is 3.37
Answer:
5-Carbon sugar
Explanation:
A nucleotide is made up of 3 things: a phosphate group, a 5-carbon sugar, and a nitrogenous base.
