Answer:

Occurs in substances that have at least one non-metal

Explanation:

The overlapping sets which is denoted by the region B is best attributed to connote with the choice "occurs in substance that have at least one non-metal".

To form an ionic bond, a metal and a non-metal must exchange electrons in order to an electrostatic attraction to occur.

In the case of covalent bonds, non-metals shares their valence electrons to form a bond by attaining an octet configuration.

So, we see that a pre-requisite for both bonds to form is a minimum of the presence of a non-metal.

Ethyl butyrate, ch3ch2ch2co2ch2ch3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange

kakasveta [241]

Answer:

14.15 g of Ethyl Butyrate

Solution:

The Balance Chemical Equation is as follow;

Butanoic Acid + Ethanol → Ethyl Butyrate + Water

Molar Mass of Butanoic Acid = 88.11 g.mol⁻¹

Molar Mass of Ethanol = 46.07 g.mol⁻¹

Molar Mass of Ethyl Butyrate = 116.16 g.mol⁻¹

Molar Mass of Water = 18.01 g.mol⁻¹

Step 1: Calculating Theoretical Yield:

According to Equation,

88.11 g (1 mol) Butanoic Acid forms = 116.16 g (1 mol) Ethyl Butyrate

So,

13.58 g Butanoic Acid will form = X g of Ethyl Butyrate

Solving for X,

X = (13.58 g × 116.16 g) ÷ 88.11 g

X = 17.90 g

Theoretical Yield = 17.90 g

Step 2: Calculating Actual Yield:

As,

%age Yield = Actual Yield ÷ Theoretical Yield × 100

Solving for Actual Yield,

Actual Yield = %age Yield × Theoretical Yield ÷ 100

Putting Values,

Actual Yield = 79.1 × 17.90 ÷ 100

Actual Yield = 14.15 g of Ethyl Butyrate
