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.
Hydrogen peroxide decomposes to yield water and oxygen gas
That is; H2O2 (l) = H2O (l) + O2(g)
The standard heat of formation; H2O2 (l) = -187.6 kJ/mol; H2O(l) = -285.8 kJ/mol
1 mole of hydrogen peroxide contains 34 g
Thus, 5.4 g contains 5.4/34 = 0.1588 moles
The moles of water produced will also be equivalent to 0.1588 moles
Heat = heat of formation of product - reactant
Therefore; Heat = (0.1588 moles × -285,8 )- (0.1588× -187.6)
= -15.594 kJ
I believe it is "The temperature of the ice sheet will be lowered" because it will most likely lower just a bit due to the heat. It's not going to fully melt but it will lower just a bit.
Plus I like your profile pic.
An atom always has the same number of protons and electrons, so it has 14 electrons.
Remembe! Dont get confused between at atom and an ion. Atoms have same number of protons and electrons but in an ion it differs,
