4 0
  • It is because we are, this is the first time in human history, where we have technology and science is widely accepted, without being ridiculed by religious figures.
  • Science can provide us with enough detailed knowledge about nature to solve and prevent environmental problems. ... It is possible to prevent pollution in the future and develop 'clean' industrial processes that have no environmental impacts.
  • Develop a product by using principles of science to encounter environment related problems
  • It is currently believed that science and technology can provide effective solutions to most, if not all, environmental problems facing western industrial societies. ... It can therefore be concluded that science and technology have only very limited potential in solving current and future environmental problems.
  • Ways Technology is Helping the Environment
  • We use Less Energy to do Things.
  • Energy Production is Becoming Cleaner.
  • Clean Energy Systems are More Effective.
  • Food Production is Becoming More Eco-friendly
  • Recycling is Reducing Waste and Pollution.
  • Cities are Becoming Less Polluted
  • We Are Becoming More Aware Of Our Effect On The Planet
  • We Can Share More Knowledge And Understanding

A student was asked to prepare 500.0 mL of 6.0 M NaOH. The student measured 120.0 g of NaOH and placed it in a 1000 mL beaker. T
Morgarella [4.7K]

Answer:

The concentration of the solution will be much lower than 6M

Explanation:

To prepare a solution of a solid, the appropriate mass is taken and accurately weighed in a weighing balance and then made up to mark with distilled water.

From

n= CV

n = number of moles m/M( m= mass of solid, M= molar mass of compound)

C= concentration of substance

V= volume of solution

m=120g

M= 40gmol-1

V=500ml

120/40= C×500/1000

C= 120/40× 1000/500

C=6M

This solution will not be exactly 6M if the student follows the procedure outlined in the question. The actual concentration will be much less than 6M.

This is because, solutions are prepared in a standard volumetric flask. Using a 1000ml beaker, the student must have added more water than the required 500ml thereby making the actual concentration of the solution less than the expected 6M.

How many molecules of carbon dioxide are in 9.080 x 10 ^-1 mol?
kakasveta [241]

Answer:

5.46 8 x 10²³ molecules.

Explanation:

  • <em>Knowing that every one mole of a substance contains Avogadro's no. of molecules (NA = 6.022 x 10²³).</em>

<em><u>Using cross multiplication:</u></em>

1.0 mole → 6.022 x 10²³ molecules.

9.08 x 10⁻¹ mole → ??? molecules.

∴ The no. of molecules of CO₂ are in 9.08 x 10⁻¹ mol = (6.022 x 10²³ molecules) ( 9.08 x 10⁻¹ mole) / (1.0 mol) = 5.46 8 x 10²³ molecules.
