Answer:
2.68 Liters
Explanation:
ideal gas law
PV=NRT
to get the volume
rearrange the formula
V=nRT/P
R molar gas constant is in units joules per mole kelvin :
8.314 J/(mol K) (joules per mole kelvin)
T temperature part of this is in kelvin so you have to convert the Celsius temperature to kelvin
1 Celsius is 274.15 kelvin so
83.4 Celsius is 356.55 kelvin
P pressure is in Pascal or Pa units
so you have to convert atm into Pa
1 atm is 201636.8 Pa or Pascals so
1.99 atm is 201636.8 Pa
V volume will be in cubic meters or m^3
m^3 will need to changed to liters
1 cubic meter or m^3 is 1000 liters
n amount of substance is in moles
again the rearranged formula is
V=nRT/P
(0.182*8.314*356.55)/201636.8 =
0.00267566693 cubic meters or m^3
1 cubic meter or m^3 is 1000 liters so
0.00267566693 cubic meters or m^3 times 1000 =
2.67566693 liters
In terms of the most common type of salt, sodium chloride, NaCl is the chemical formula of this salt,
Answer:
oof idk I would suggest looking at an example and try going off that

<h3><u>Explanation</u>:</h3>
The reaction rate of the metals with water, steam, acid, or hydroxides or their inert behavior towards them are noted in the metal activity series.
It contains all the metals one after the other which and the upper metal can replace the lower metal from its salt.
Calcium can replace hydrogen from acid, so the reaction will occur in 18. The products formed are calcium phosphate and hydrogen gas.
Chlorine is more reactive than bromine. So it can replace bromine from its salt to from bromine gas and magnesium chloride.
Aluminium can replace iron from its salt. So it will form aluminium oxide and iron metal. This reaction is used to obtain iron from ores.
Zinc can replace hydrogen from acid. So the products will be zinc chloride and hydrogen gas.
Chromium cannot displace hydrogen form water. So the reaction won't occur.
Tin can replace hydrogen form acid. So the reaction will proceed.
Magnesium will replace platinum from its salt. So magnesium oxide and platinum will form.
Bismuth cannot replace hydrogen from acid. So the reaction won't proceed.
