Answer:
The answer is Erosion, Weathering,
Explanation:
<u>These all seem to be correct but i know for a fact those two are correct.</u>
Answer:
equal and opposite
Explanation:
The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object
The dissociation of a weak acid/base in solution is not complete.
<h3>Strong acid and strong base</h3>
A strong acid is an acid that dissociates completely in solution. A strong base is a base that dissociates completely in solution.
A weak acid do not dissociate completely in solution and a weak base do not dissociate completely in solution.
The equation of the dissociation of a strong acid/base goes to completion while that of a weak acid or base is reversible with the equilibrium position lying closer to the left hand side.

Answer:
ΔH° = -1815 kJ
Explanation:
The balanced chemical equation
C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(l)
tells us that 2220 kJ joules are released in the combustion of one mol propane,C3H8 . So what we need to solve this problem is to find how many moles of propane 20.0 L represent and do the calculation.
To do that, we will be using the Ideal Gas Law since we are told the volume, temperature, and pressure.
PV = nRT ∴ n = PV/RT
P: 1 atm
V: 20.0 L
R= 0.08206 Latm/kmol ( R constant for ideal gases)
T= 25 ºC + 273 = 298 k (Need to convert T to degree Kelvin)
Plugging the values
n = 1 atm x 20.0 L/ (0.08206 Latm/ k mol)
n = 0.82 mol
ΔH° =(-2220 kJ / 1 mol C3H8 ) 0.82 mol C3H8 = -1815 kJ
Vitamin K and potassium are essential micronutrients the body needs to develop and function properly. The two share some things in common, but they’re not the same.
Each has a unique set of properties and purposes. Unlike vitamin K, potassium is not a vitamin. Rather, it’s a mineral.
On the periodic table, the chemical symbol for potassium is the letter K. Thus, people sometimes confuse potassium with vitamin K.
This article highlights some of the main similarities and differences between vitamin K and potassium.
