One problem caused by technology is pollution
balandron [24]
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!☺

Name the types of polymerization and the differences​
Talja [164]
Condensation polymerization : releasing water as by product, occurs in monomer that has functional group that can react with each other e.g alcohol&carboxlic acid to form polyesters, carboxylic acid and amines to form polyamides,etc.

Radical Polymerization: occurs by propagating radical monomers or monomer that has unsaturated bonds, such as ethene, initiated by formation of radical from the monomer by using uv lights/other initiator, does not produce any by products

A 50°C solution has a pH of 3.30. At this temperature, Kw = 5.48 x 10 9. What is the pOH of the solution?
sammy [17]

Answer:

9.93

Explanation:

Your value for Kw is incorrect. The correct value is 5.48 × 10^-14.

  pH + pOH = pKw

3.30 + pOH = -log(5.84 × 10^-14) = 13.23

          pOH = 13.23 - 3.30 = 9.93

The pOH of the solution is 9.93.

What is the chemical potential of an element in its standard state? Select the correct answer below: −1.00kJ/mol 0kJ/mol 1.00kJ/
Elenna [48]

Answer:

0 kJ/mol.

Explanation:

Hello,

In this case, since the chemical potential can be represented in terms of the Gibbs free energy of formation:

\mu = \frac{\Delta _fG}{n}

Thus, since the Gibbs free energy of formation of an element is zero, the chemical potential is also zero, or just 0 kJ/mol.

Best regards.
