Answer:
Order of the cycle:
Step -1>>>>Step -4 >>>> Step -3 >>>>> step -2.
Explanation:
<u>Step -1:</u>
Carbon dioxide is taken in by plants during photosynthesis.
<u>Step -4;</u>
The animal eats a plant and uses its carbohydrates for energy.
<u>Step - 3</u>
The animal releases the carbon dioxide back into the atmosphere during respiration.
<u>Step -2</u>
The cycle repeats when the carbon stored in the atmosphere as carbon dioxide gas is taken in.
Therefore, order of the cycle is Step -1>>>>Step -4 >>>> Step -3 >>>>> step -2.
Answer:
Social justice aims to give individuals and groups fair treatment and an impartial share of social, environmental and economic benefits. The concept promotes the fair distribution of advantages and disadvantages within a society, regardless of background and status.
Environmental justice deals explicitly with the distribution of environmental benefits and the burdens people experience, at home, at work, or where they learn, play and spend leisure time. Environmental benefits include attractive and extensive greenspace, clean air and water, and investment in pollution abatement and landscape improvements. Environmental burdens include risks and hazards from industrial, transport-generated and municipal pollution.
Plants are chlorophyll-containing photosynthetic organisms. Thus, they convert solar or radiant energy into chemical energy under the process termed as photosynthesis.
<u>Explanation:</u>
- Plants are chlorophyll-containing photosynthetic living beings. Consequently, they convert radiant energy into chemical energy under the procedure named photosynthesis.
- Except for remote ocean hydro-thermal environment, the sun is the only source for all biological systems on earth. Plants catch just 2-10 percent of the solar radiation and transmit it as chemical energy. All creatures are reliant for their nourishment on producers (plants), either directly or indirectly. So there is a stream of energy from the sun (radiant energy) to producers and then to consumers (chemical energy).
Answer : The internal energy change is, -506.3 kJ/mol
Explanation :
Formula used :
or,
where,
= change in enthalpy = 
= change in internal energy = ?
= change in moles
Change in moles = Number of moles of product side - Number of moles of reactant side
According to the reaction:
Change in moles = 0 - 2 = -2 mole
That means, value of 
= 0
R = gas constant = 8.314 J/mol.K
T = temperature = 
Now put all the given values in the above formula, we get
Therefore, the internal energy change is -506.3 kJ/mol
The molarity of the hydrogen peroxide solution from the information supplied in the question is 12.26 M.
Co = 10pd/M
Where;
Co = concentration = ?
p = percent of the hydrogen peroxide = 30%
d = Density of hydrogen peroxide = 1.39 g/ml
M = Molar mass = 34 g/mol
Substituting values;
Co = 10 × 30 × 1.39/34
Co = 12.26 M
The molarity of the hydrogen peroxide solution from the information supplied in the question is 12.26 M.
