I wrote the answer on this paper and here is the calculations step by step
very sry the "V" must be replaced with 285 and the 285 must be replaced with "V" and the answer is 231.09 cm3. sorry for the inconvenience.
A sedimentary rock is a rock formed from water. An igneous rock is a rock that is formed by magma ( lava from a volcano ). A metamorphic rock is a rock formed by heat or pressure.
<span> a) AgNO3 (aq) + KCl (aq) --> AgCl (s) + KNO3 (aq) this is balanced chemical equation
</span><span>AgCl is the precipitate so we shall not split it
</span><span>Ag+(aq) + NO3 -(aq) + K+ (aq) + Cl-(aq) --> AgCl (s) + K+(aq) + NO3-(aq)
</span><span>Ag+ (aq) + Cl- (aq) ---> AgCl (s) after removing ions</span>
They differ in their molecular structures and properties.
Benefits of friction.
1. Walking. Friction between the soles of our shoes and the ground enables us to walk. The sole of the shoe is held to the ground through friction. This is what is termed as "grip" of the shoe. The more grip a shoes offers, the better and faster we can walk.
2. Writing. Writing using a pen requires friction. It is impossible to hold a pen in the hand without friction because it would slip out. Also the graphite point of the pencil would not make a mark on the paper without friction.
Drawbacks of friction
1. Drag. An aircraft taking off experiences significant friction between it and the air resulting in drag, so much fuel has to be used to create energy to overcome the wind resistance.
2. Surface hindrance. Friction makes moving something heavy from one part of a room to another very difficult. Sliding a large box across the flour takes a lot of energy due to friction between the box and the floor.
