Both the atomic mass and the atomic number increase from left to right
Sand doesn't directly cause weathering because sand is made via weathering. When rocks get weathered they become sand. But maybe when the sand and wind work together they might be able to weather some rocks
Answer:
4.921.
Explanation:
- It is an acidic buffer solution;
∵ pH = pKa + log[salt]/[acid].
<em>∴ pH </em>= - log(1,8 x 10⁻⁵) + log[0.75/0.50] = 4.745 + 0.1761 = <em>4.921.</em>
The "Ideal Gas Law Equations" is

P= Pressure (in Pascals)
V=Volume (in Liters)
n=amount, or <u>
n</u>umber (in moles)
R= 8.3145

or

T= Temperature (In Kelvin)

Plug into the equation and you're good!



If your teacher cares about sig figs,
2 sig figs (significant figures)

For other units of pressure,
1 atm = 760 mmHG = 760 Torr = 101326 Pa = 1.01325 bar<u />
Because it is toxic to humans if absorbed or consumed.
