Answer:
Sounds travels in transverse waves requires a medium to travel through
Answer:
A) SiO2 is the limiting reactant
B) Theoretical yield= 72333.3g
C) % yield =91.5%
Explanation:
SiO2(s) + 2C(s) --------------> Si(s) + 2CO(g)
n(SiO2)= 155000/60 = 2583.33 mols
n(C)= 79000/12= 3291.66 mols
a)SiO2 is the limiting reactant
According to the balanced reaction equation,
60g of SiO2 produced 28g of SiO2
155000g of SiO2 will produce 155000×28/60= 72333.3g
Therefore theoretical yield of Si= 72333.3g
% yield= 66200/72333.3×100/1 =91.5%
Answer:
a. The fish are dying due to factory pollution making the water of the pond uninhabitable.
b. The pond can be neutralized by adding something basic to balance the pH levels of the pond, or by adding significant amounts of water to dillute the acidity of the pond.
Answer:
Option a incompressible
Explanation:
Liquids have definite volume, but indefinite shape.
Liquids take the shape of the container . When a liquid is inside a container, it will take its shape. Unlike gases, a liquid cannot change its volume to spread out and completely fill a container. Hence a liquid cannot be compressed.
Immiscible is not right because this applies only when two liquids are there
Surfectants are compounds that reduce the surface tension between two liquids or a liquid or a gas, etc.
Hence here appropriate choice is
a) incompressible
