Answer:
A. increasing the ability of technology, like microscopes, to see even smaller particles
Answer:
0° Celsius
Explanation:
The thermometer shows 0° Celsius which corresponds to 32° F.
Within the categories of homogeneous and heterogeneous mixtures there are more specific types of mixturesincluding solutions, alloys, suspensions, and colloids. A solutionis a mixture where one of the substances dissolves in the other. The substance that dissolves is called the solute.
Answer:
See explanation.
Explanation:
Hello!
In this case, since the main molecular reaction that is taken place in the beaker is:
In such a way, we understand that one breaker contained silver nitrate and the other one barium iodide. Thus, the complete molecular equations turns out:
Now, for the complete ionic equation, we just ionize the aqueous species:
Finally, for the net ionic equation we cancel out barium and nitrate ions as the spectator one because they are both sides on the equation:
Best regards!

ft= (m1 cp1 t1 + m2 cp2 t2 + .... + mn cpn tn) / (m1 cp1 + m2 cp2 + .... + mn cpn) (1)
where,
1000g = 1kg
ft(t eg)= final mixed temperature (°C)
m = mass of substance (kg)
cp = specific heat of substance (J/kg°C)
t = temperature of substance (°C)
