Answer:
A. Antoine Lavoisier
Explanation:
He is know for creating the first chemical textbook. This textbook included rules for naming different chemical compounds, which is the still the same method we use to this day.
Hoped this can help! :D
Answer: Temperature of one liter of phosphine gas with a mass of 1.725 g and gas pressure of 0.9910 atm is 
Explanation:
According to the ideal gas equation:
PV=nRT
P = Pressure of the gas = 0.9910 atm
V= Volume of the gas= 1.0 L
T= Temperature of the gas in kelvin = ?
R= Gas constant =
n= moles of gas= 


Thus the temperature (in °C) of one liter of phosphine gas with a mass of 1.725 g and gas pressure of 0.9910 atm is 
the fact that u would post ur whole test on here i see if u posting 3 but the whole test Girllllllllll
78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide and small concentrations of other elements. <span />
Answer:
45K
Explanation:
Rise in temperature = Final - initial temperature.
temperature in K = Temperature in Celsius + 273
for Celsius; T2 -T1 =45°C
for kelvin; T2+273 -(T1+273) = ?
T2+273 -T1-273 =?
T2-T1 = ?
T2-T1 =45k
hence ΔT(K) = ΔT(°C) (temperature difference in Celsius is equal to temperature difference in kelvin)
