The molar mass of the weak acid is calculated as follows
by use of an example of monoprotic weak such as CH3COOH reacting with NaOH
that is NaOH + CH3COOH = CH3COONa + H2O
calculate the moles of NaOH used
= molarity x volume/1000
= 44.6 ml x 0.100/ 1000 = 4.46 x10^-3 moles
by use of mole ratio between NaOH to monoprotic acid which is1:1 the moles of monoprotic acid is also 4.46 x10^-3 moles
molar mass is therefore = mass/ moles = 0.139 g/ (4.46 x10^-3) = 31.17 g/mol
Osmosis deals only with D. Water. Diffusion and Osmosis are relatively the same thing besides the fact that water is largely incorporated with the osmosis.

➷ Iron would be attracted to a magnet therefore, you can hover a magnet over the mixture. Doing this would lift out the iron fillings, leaving the sand behind.

Answer: The mole ratio of sodium to sodium chloride 2:2.
Explanation:
As the given reaction equation is as follows.
Here, 2 moles of sodium reacts with 1 mole of 
and leads to the formation of 2 moles of NaCl.
This means that 2 moles of sodium gives 2 moles of NaCl on reaction with chlorine.
Hence, the ratio of moles of sodium to sodium chloride is 2:2.
Thus, we can conclude that the mole ratio of sodium to sodium chloride 2:2.
I think this is true because..
technology negatively affects the environment by compromising human health and safety... endangering natural ecosystem and biodiversity... having a cumulative impact on global systems... and depleting natural resources. Technology positively affects the environment through the application of environmental science to solve problems caused by human environmental impact.
Risks to humans from environmental damage through technology include inhalation of dangerous chemicals in air pollution, contamination of water and food sources, and risk of infections and diseases through exposure to toxic wastes. Flora and fauna risk habitat loss or disruption and extinction of species through exposure to dangerous byproducts of technology. Greenhouse gases affect atmosphere and weather systems, causing global warming and chlorofluorocarbons that deplete the Earth's ozone layer. Technology consumes resources which are not necessarily renewable, including living resources, such as forests and populations of fish, and inanimate resources, such as natural chemicals and minerals.
Although technology damages the environment in many ways..it can also have the capability to limit or prevent damage using such environmental technologies such as recycling...the exploitation of renewable energy sources such as solar power and wind power... the purification of polluted air and water,and the treatment of sewage and factory wastes.. and the development and production of devices that promote energy conservation.....so this is why i think this is the answer! ☺
Hopefully this helped you!☺
