Explanation:
everthing is made of matter so d is the only answer
Answer:
n ≈ 2.42 moles
General Formulas and Concepts:
<u>Chem</u>
Ideal Gas Law: PV = nRT
- P is pressure in mmHg
- V is volume in liters
- n is number of moles
- R is a constant (62.4 L · mmHg/mol · k)
- T is temperature in Kelvins
K = °C + 273
Explanation:
<u>Step 1: Define</u>
V = 50.2 L
P = 755 mmHg
T = -22.0°C = 251 K
<u>Step 2: Find moles </u><em><u>n</u></em>
(755 mmHg)(50.2 L) = n(62.4 L · mmHg/mol · k)(251 K)
37901 mmHg · L = n(15662.4 L · mmHg/mol)
n = 2.41987 moles
<u>Step 3: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules.</em>
2.41987 moles ≈ 2.42 moles
Alter means change. So when a wave hits a big rock, the rock sheds a tiny bit, creating sand.
hope this helped! Please put this as a brainliest answer
The four metals that will not replace hydrogen in an acid are Cu, Ag, Au, Hg.
Explanation:
- As Copper Cu lies below the hydrogen, this is why it is less reactive and ca not replace Hydrogen from its compound.
- Silver Ag also lies below the hydrogen and therefore it is less reactive to displace Hydrogen.
- Gold Au becomes less reactive than Hydrogen due to its placement below Hydrogen acid.
- Mercury Hg is less reactive than Hydrogen
