Answer:
C: liquid
Explanation:
Liquid has the set volume as it cannot be compressed or 'expanded' like a gas. However, liquids will take the shape of the container you put them in so their shape can change.
Answer:
Volume = 44.96L
Explanation:
p = 427mmHg = 0.56atm
R = 0.08206
T 6°C = 279k
V = ?
n = 1.10 mol
using ideal gas equation
pv=nRT
0.56 x V = 1.10 x 0.08206 x 279
0.56 x V = 25.18
V = 25.18/0.56
V = 44.96L
The balanced chemical reaction is:
<span>K2CrO4(aq) + PbCl2(aq) → 2KCl(aq) + PbCrO4(s)
We are given the amount of the reactants to be used for the reaction. These amounts will be the starting point of our calculations. </span>
<span>
3.0 M K2CrO4 (.500 L) = 1.5 mol K2CrO4
</span>1.5 mol K2CrO4 (1 mol PbCrO4 / 1 <span>mol K2CrO4</span>) ( 323.2 g/mol)=484.8 grams PbCrO4
Therefore, the best answer from the choices is 480 grams.
The third one is the answer
