It's been a while... but I'm <em>pretty</em> sure it's
H₂O₄
Answer 15m
Explanation: Distance = Speed x Time
3 x 5 =15
Answer: 9.18 Litres
Standard Temperature and Pressure (STP). Think of this as the perfect environment where the Temp. is 0°C or 273 Kelvin and Pressure is always 1 atm. This is only true in STP.
This question uses the Ideal Gas Equation:
PV=nRT
P= 1 atm
V = ??
T = 273 K (always convert to Kelvin unless told otherwise)
n = 0.410 mol
R = 0.0821 L.atm/mol.K
What R constant to use depends on the units of the other values. (look at the attachments) The units cancel out and only Litres is left. You simply multiply the values.
Answer:
A. the jar covers
Explanation:
An independent variable is what you, as the scientist, changes.
Density = Mass ÷ Volume. You get 2.466
