Answer:
mainly metal oxide use to react with both acid and bases to form salts such as zinc, aluminum etc.
Explanation:
1mM of solution means millimolar, that is 1 millimole of solute is contained in 1 liter of solvent.
Converting mM to M,
150mM to M = 150*1 x 10^-3
= 0.15M
Number of moles = molar concentration * volume
= 0.15*0.5
= 0.075 moles.
Molar mass of NaCl = 23 + 35.5
= 58.5 g/mol
Mass of NaCl = molar mass * number of moles
= 58.5*0.075
= 4.3875g
Description:
• 4.3875 g of NaCl is measured on a measuring scale and poured in a conical flask.
• 1 liter of solvent is measured with a measuring cylinder and poured into the conical flask and mixed.
Im in the 10th grade and i got not a clue how to do this dawg
Hard materials such as brick walls tend to (block sound waves, they bounce off of the brick creating an echo) sound waves while soft materials such as thick carpet tend to (absorb sound waves).
Hope this helps!
