Which type of society survives mainly by foraging for food?
Dennis_Churaev [7]
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.

JulsSmile [24]

Answer:

2.1

Explanation:

Calculation of moles of Ba(OH)_2.8H_2O

Mass of copper = 5.3 g

Molar mass of copper = 315.46 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{5.3\ g}{315.46\ g/mol}

Moles of Ba(OH)_2.8H_2O = 0.0168 moles

According to the reaction,

Ba(OH)_2.8H_2O + H_2C_2O_4.2H_2O\rightarrow BaC_2O_4 + 12 H_2O

1 mole of Ba(OH)_2.8H_2O react with 1 mole of  H_2C_2O_4.2H_2O

0.0168 moles of Ba(OH)_2.8H_2O react with 0.0168 moles of  H_2C_2O_4.2H_2O

Moles of H_2C_2O_4.2H_2O = 0.0168 moles

Molar mass of H_2C_2O_4.2H_2O = 126.07 g/mol

Thus,

<u>Mass = Moles * Molar mass = 0.0168 moles * 126.07 g/mol = 2.1 g</u>

<u>Answer - 2.1</u>
