<u>Answer:</u> The volume of stock NaCl solution needed is 23 mL
<u>Explanation:</u>
To calculate the molarity of the diluted solution, we use the equation:
where,
are the molarity and volume of the stock NaCl solution
are the molarity and volume of diluted NaCl solution
We are given:
Putting values in above equation, we get:
Hence, the volume of stock NaCl solution needed is 23 mL
Answer:
Temperature
Explanation:
temperatures below 0 degrees celsius will turn water into ice
Temperatures 1 to 99 degrees celsius is water in liquid form
Temperatures of over 100 degrees celsius liquid turns into gas
Ra, would have the lowest ionization energy. Remember ionization energy increases going up and to the right.
Answer:
The steps are arranged in the following order, describing how carbon dioxide and photons impact the earth's warming.
Explanation:
The sequence is in the following order;
- The sun radiated sunlight (visible) photons
- Photons from the sun strike the earth and become infrared photons
- Earth radiates infrared photons into the atmosphere
- CO2 in the atmosphere absorb infrared photons
- CO2 in the atmosphere emit infrared photons back towards earth
Carbon dioxide (CO2) molecules can absorb energy from infrared (IR) radiation. Due to vibrations caused by this absorption, the CO2 molecules later release extra energy by emitting another infrared photon.
This ability of CO2 molecules to absorb and re-emit infrared energy is what makes it an effective heat-trapping greenhouse gas.
