Answer:
Water
Explanation
there is a hard way and an easy way to do this either you fill it up with cold water and it takes longer to disolve or you use hot/room temp water and it disolves faster because the sault particles slowly break of from one another and then disolve with in the water
Multiply then divide 12g by 4cm3 because 4cm3 equals 64cm divide by 12g or multiply which ever is in the options
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!☺
