A. sedimentary
because the current will mold the mud and sand into rocks and currents forming rocks is a sedimentary rock formation
Sorry am not sure I only remember solid and gas that’s all
Answer:
In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time. Exact conservation laws include conservation of energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge.

Answer:
Molarity = 8.89 mol/L
Explanation:
Given data:
Mass of hydrogen peroxide = 3%
Density = 1.01 g/mol
Molarity = ?
Solution:
3% hydrogen peroxide means 3 g of H₂O₂ are present in 100 g of solution.
Now we will calculate the moles of H₂O₂.
Number of moles = mass / molar mass
Number of moles = 3g/ 34 g/mol
Number of moles = 0.88 mol
Now we calculate the volume of solution.
d = m/v
v = m/ d
v= 100 g/ 1.01 g/ mL
v = 99 mL
In Litter
v = 99 / 1000 = 0.099 L
Molarity:
Molarity = number of moles / volume in L
Molarity = 0.88 mol/ 0.099 L
Molarity = 8.89 mol/L

What is equilibrium reaction ?
In a chemical reaction, chemical equilibrium is the state in which both the reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.
PbI2 + 2OH- (aq) ----> Pb(OH)2(s) + 2I- (aq)
Pb(OH)2 is insoluble therefore increasing pH will lead to the formation of the more solid lead (ll)hydroxide which will help to solubulate more PbI2
therefore equilibrium will shift to right side means increasing pH will increase solubility of the PbI2.
