Answer:
1258 grams of AgN03
Explanation:
We calculate the weight of 1 mol of AgN03:
Weight 1 mol AgN03= Weight Ag + Weight N +( Weight 0)x3=108g+ 14g+16gx3=170 g/mol
1 mol----170 g AgN03
7,4mol---x= (7,4 mol x170 g AgN03)/1 mol=1258 g AgN03
Answer:Fe2O3
Explanation:
the roman numeral tells you the charge of the metal, and you know oxygen is -2 charge so you need the least common multiple of +3 and -2 so that they cancel out, which is 6 so you need 2 of the +3 and 3 of the -2
Answer:
Fe 3+
Explanation:
iron is Fe and it's 3 and has positive
All substances are matter but all matters are not substance. Matter is generally a loose term used in respect to a substance. Matter and substance are sometimes used for the same context, this is certainly not correct. Various examples have already proved that a matter will not always be a substance depending on its physical nature, but a substance is always a matter.
(cc/ to Taskmasters , I just switched it up a little bit.)
O ice at 0°C
O liquid water at 90°C
O steam at 100°C
The average kinetic energy of water molecules is greatest in steam at 100°C.
Water is a polar solvent that has potential energy on its own which can be converted to kinetic energy once the water is in motion.
The kinetic energy is that energy that a moving body possesses.The faster a molecule moves, the more kinetic energy it has, and the higher the measured temperature.
That being said, when the temperature of water is increased, there would be increased molecular motion leading to a higher kinetic energy.
Therefore, the average kinetic energy of water molecules is greatest in steam at 100°C.
