Answer:

C = 1

Explanation:

For a strong acid, equation of dissociation reaction;

HX(aq) + H2O(l) —> X- + H3O+

For a strong acid, the equilibrium reaction lies strongly to the right.

pH = -log10[H3O+] = -log10[0.1] = -(-1) = 1.

Answer : Option C) 1

Explanation : Using the formula for finding pH of strong acid,

pH = - $log_{10}$ [ $H^{+}$ ] = - $log_{10}$ [0.1]
= - $log_{10}$ $10^{-1}$ = - (-1) = 1.

This calculation shows how to find the pH of any acid if the concentration is given.

What is the percent yield of either if 1.11L(d=0.7134 g/mL) is isolated from the reaction of 1.500L of C2H5OH

serg [7]

Answer:

Percent yield of ether = 83.18%

Explanation:

Equation of the synthesis reaction of ether from ethanol is given as follows :

2 C₂H₅OH -----> C₂H₅OC₂H₅ + H₂0

Density = mass / volume

Therefore mass = density × volume

Density of ether = 0.7134 g/mL; volume of ether produced = 1.11 L = 1110 mL; Molar mass of ether = 74 g/mol

Mass of ether produced = 0.7134 g/mL × 1110 mL = 791.874 g

Density of ethanol = 0.789 g/mL; volume of ethanol = 1.50 L = 1500 mL; molar mass of ethanol = 46 g/mol

Mass of ethanol reacted = 0.789 g/mL × 1500 mL = 1183.5 g

From the equation of reaction, 2 mole of ethanol produces 1 mole of ether

Mass of 2 moles of ethanol = 2 × 46 = 92 g

Therefore, 92 g of ethanol produces 74 g of ether

1183.5 g of ethanol will produce 1183.5 × 74/92 grams of ether = 951.945 g of ether

Percent yield of ether = actual yield/theoretical yield × 100%

Actual yield of ether = 791.874 g; theoretical yield of ether = 951.945 g

Percent yield of ether = (791.874 g × 951.945 g) × 100 %

Percent yield of ether = 83.18%

Most foods that are high in calcium are poor sources of iron. this statement illustrates the characteristic of a nutritious diet

natka813 [3]

Most foods that are high in calcium are poor sources of iron. this statement illustrates the characteristic of a nutritious diet known as balance.

Nutrition is the biochemical and physiological processes by which organisms use food to sustain life. It provides organisms with nutrients that can be metabolized to produce energy and chemical structures. An inadequate supply of nutrients leads to malnutrition.

Although these two definitions may seem similar, there are differences. Health simply means food that protects you from disease and keeps you alive. Nutrient-rich foods mean foods that provide sufficient nutrients (vitamins, carbohydrates, proteins) that the body needs to survive the kind that is either low in fiber or high in fat, salt, and/or sugar. Eating too much food or drink.

What gives bases their properties?

svp [43]

Bases are iconic compounds that produce negative hydroxide ions (OH-) when dissolved in water. Bases taste bitter, feel slippery, and conduct electricity when dissolved in water.... Bases turn red litmus paper blue. The strength of bases is measured on the pH scale.
