Question

Расчитайти объём (при нармальных условиях ) 12 грамм углекислого газа Определите степень окисления каждого элемента : O2 , MgO , ZnS , BaCL2 , Mg(NO3)2

Answer 1

Дано
m(CO₂)=12г
найти
V
n=m/M
M(CO₂)=12+2*16=44г/моль
n=12/44=0,27моль
V=Vm*n=22,4*0,27=6,048л

Answer 2

Calculation of the Volume of 12 grams of Carbon Dioxide at Standard Conditions

To calculate the volume of 12 grams of carbon dioxide (CO2) at standard conditions, we need to use the ideal gas law equation. The ideal gas law equation is given by:

PV = nRT

Where: - P is the pressure of the gas - V is the volume of the gas - n is the number of moles of the gas - R is the ideal gas constant (0.0821 L·atm/(mol·K)) - T is the temperature of the gas in Kelvin

At standard conditions, the pressure is 1 atmosphere (atm) and the temperature is 273.15 Kelvin
