Answer: 0 K
Explanation:
This is a fact - absolute zero is defined as 0 degrees Kelvin.
The size of the crystal can tell you where it formed. Magma cooling temps determine the size
Alkali metals will always contain one valence electron but the electron configuration will depend on the element
The appropriate response is infrared waves. Indeed, even in the darkest of conditions, there are modest bits of light present. Some of this light might be the infrared light that isn't obvious to the stripped eye. Night vision goggles utilizing picture upgrade innovation gather all the accessible light, including infrared light, and open up it with the goal that you can without much of a stretch see what's happening oblivious.
Answer:
2 moles of solute.
Explanation:
Molarity is defined as number of moles of solute present in one litre of solution.
Hence one molar solution of NaCl means 1 mole of NaCl is present in 1 litre of solution.
Molarity = 
For 1 litre of solution 1 mole of solute is required to make a one molar solution.
Hence for 2 litres of solution we require 2 moles of solute to keep it one molar.
