The appropriate answer is a. HUNTER-GATHERER. Hunter-gatherer societies are nomadic and they forage for edible plants, bean, fruits and nuts. They also hunt wild game for food. Early humans in the Neolithic period practiced this way of life. 
Agrarian societies thrive on agriculture which they depend on for sustainable and for trade. Animals and plants are domesticated and so people can settle and build a society. Pastoral agriculture is a semi-nomadic lifestyle where the society is centered around keeping herds of grazing animals. Industrial societies focus on manufacturing and this is the backbone of the society.

You will analyze four substances in this lab. Based on their chemical formulas and what you already know about covalent and ioni
Phoenix [80]

Answer: Oil: covalent

Cornstarch: Covalent

Sodium chloride: Ionic

Sodium bicarbonate: Ionic

Explanation: Covalent compounds are formed by sharing of electrons between non metals whereas ionic compounds are formed by transfer of electrons from metals to non metals.

1. Oil, which is built from the nonmetals hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.

2. Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.

3. Sodium chloride (table salt), whose formula is NaCl is formed by transfer of electrons from sodium to chlorine.Ionic compounds are soluble in water.

4. Sodium bicarbonate, whose formula is NaHCO_3 is formed by transfer of electrons from sodium to HCO_3.Ionic compounds are soluble in water.

1. Calculate the number of moles of carbon dioxide formed when 40.0 moles of oxygen is consumed in the burning of propane. Note
Andrews [41]

Answer:

1. D (24.0 moles CO2)

2. A (.239 moles H2)

Explanation:

1. First Balance the equation

1 C3H8 + 5 O2 ---> 3 CO2 + 4 H2O

Then set up a stoiciometric equation so that the moles of O2 cancel out

40mol O2 x \frac{3 mole CO2}{5 mole O2} = 24.0 moles CO2

2. Set up a stoichiometric equation

10 grams Fe x \frac{1 mole Fe}{55.85 grams Fe} x \frac{4 mole H2}{3 mole Fe} = 0.239 moles H2
