If it is a big open wound you apply pressure
The ones that are known to be corrosive are PETE and PVC. These plastics you need to avoid because these are <span>plastics that can be hydrolyzed by alkaline solutions. Hope this helps on your task</span>
Answer:
Chemical weathering
Explanation:
This is a chemical weathering since chemical change is involved. water flows through the rock, it dissolve the rock particles, reacting with the minerals salts in the rock there by producing new substances, ultimately leading to wearing off of the rock particles
Explanation:
Sol. 450 ml there is LiCl 200 g
Sol. 1000 ml there is LiCl 200/450×1000
= 444.44 g
Molar = g/molar mass = 444.44/42.394 = 10.48 M
Answer: 4.86 x 10⁻³ mole.
Explanation:
- The number of moles can be calculated using the relation; n = mass / molar mass.
- n is the number of moles, mass is the mass of the substance in g (m = 0.5 g), and molar mass of NaBr = 102.894 g/mole.
- n = mass / molar mass = (0.5 g) / (102.894 g/mole) = 4.86 x 10⁻³ mole.
