Answer:
in monoculture farming , we produce a single species of a livestock or plant in large quantity.
Even though it is very effective, producing a mass number of a single organism in an Area will risk of endangering the existence of a specific nutrient ( because that large number of organism is basically eating the same thing)
which lead to societal decision such as the founding of The Livestock conservancy, or other environmental protection organization
Explanation:
Paleolithic Era
During the Paleolithic Era, early humans used mostly stone tools but at times also used wood or bone tools.
<u>Answer:</u> The moles of chlorine gas produced is 5.5 moles
<u>Explanation:</u>
We are given:
Moles of HCl = 11 moles
For the given chemical reaction:
By Stoichiometry of the reaction:
4 moles of HCl produces 2 moles of chlorine gas
So, 11 moles of HCl will be produced from 
of chlorine gas
Hence, the moles of chlorine gas produced is 5.5 moles
Answer:
0.062J
Explanation:
Given parameters:
Height of raising the spoon = 21cm
Mass of spoon = 30g
Unknown:
Gravitational potential energy = ?
Solution:
The gravitational potential energy of a body is the energy by virtue of the position of a such a body in space.
It is given as:
G. P. E = mgh
where m is the mass
g is the acceleration due to gravity
h is the height
Convert the parameters to appropriate units.
21cm to m gives 0.21m
30g to kg gives 0.03kg
G.P.E = 0.03 x 9.8 x 0.21 = 0.062J
The new volume if the balloon is cooled at constant pressure is 3.98 L.
Charles's law, states that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature if the pressure remains constant.
The new volume is calculated using the Charles law formula
V₁ / T₁ = V₂ / T₂
where,
V₁ = The initial volume of air = 4.24 l
T₁ = 23.00 °C into kelvin = 23 +273 =296 K
T₂ = 5.00 °C into kelvin = 5.00 + 273 = 278 K
V₂ = ?
By making V₂ subject the subject of the formula by multiplying both sides by T₂
V₂ = ( V₁ × T₂ ) / T₁
V₂ = (4.24 L × 278 K) / 296 k
= 3.98 L
Therefore, the new volume, if the balloon is cooled at constant pressure, is 3.98 L.
An air-filled balloon will contract when chilled and expand when heated. This occurs because the gas that makes up the air within the balloon expands when it is warm and contracts when it is cool.
