Answer:
Silver and copper
Explanation:
Siliver
Electrical conductivity=62000000(s/m)
Boiling point=2162
Melting point=961.78
Phase=solid
Copper
Electrical conductivity=59000000(s/m)
Boiling point =2927
Melting point=1084.62
Phase=soild
Metals like gold, silver and copper are drawn into thin wire and are used in an electric circuit because of their high electrical conductivity
Mostly Siliver and copper are used since using gold is much expensive.
Answer:
3.213J/mol
Explanation:
first specific heat capacity of water = 4200J/Kg K
Q=mass×temperature difference×specific heat capacity
Q=1.53×(24.3-20)×4200
Q=25.704 J
heat of solution= quantity of heat ÷ amount of substance
heat of solution= 25.704÷8
heat of solution= 3.213J/mol
Answer:
C) Carla participated in an artistic activity, while Maurice participated in a scientific activity.
Explanation:
Scientific activities involve making observations, which ultimately leads to the series of steps that aims at solving the observed problem or answering a question that arises from the problem. This is the case of Maurice who is observing and recording information about ants in order to solve a curiosity (about what they feed on).
However, on the other hand, Carla is given a pictorial representation of the ants and what they carry. It is not based on curiosity or to answer a question about the ants but rather for decoration or aesthetic purposes, which is what makes her activity artistic.
Answer:
hello
Explanation:
second option is correct answer
<span>It was a heterogeneous mixture.
Since you were able to separate the mixture than means they are heterogeneous mixture </span>
