The volume of water that will be produced from the reaction will be 6.3 mL
<h3>Stoichiometric calculation</h3>
From the equation of the reaction:
The mole ratio of hydrogen sulfate to sodium hydroxide is 1:2.
Mole of hydrogen sulfate = 0.50 x 350/1000 = 0.175 moles
Mole of 15 grams sodium hydroxide = 15/40 = 0.375 moles
Thus, hydrogen sulfide is the limiting reagent.
Mole ratio of hydrogen sulfide to water = 1:2.
Equivalent mole of water = 0.175 x 2 = 0.35 moles
Mass of 0.35 moles of water = 0.35 x 18 = 6.3 grams.
1 gram of water = 1 ml.
Thus, 6.3 grams of water will be equivalent to 6.3 mL

Scientists use radioactive decay to date fossils and artifacts through a process called "carbon dating," which measures the amount of carbon still left in a dead object. The less carbon that exists, the longer that animal or plant as been dead.
Answer: -
280mg
Explanation: -
The chemical formula is C14H18N2O5
Molar mass of the compound = 12 x 14 + 1 x 18 + 14 x 2 + 16 x 5 = 294 gram
Number of nitrogen atoms present in the formula = 2
Mass of nitrogen present= 14 x 2 = 28 gram
Thus 294 gram of the compound has 28 gram.
Hence 2.95grams of the compound has (28 gram x 2.95 gram / 294 gram)
= 0.28 gram
= 280 mg
Thus 280 mg of nitrogen is present in 2.95 grams of C14H18N2O5
Both of the choices are nonpolar.
In the modern periodic table, elements are arranged by increasing atomic number.
