Answer:
1& 4
Explanation:
1. The average kinetic energy of the particles in a substance determines the substance's temperature.
4. How fast a substance's particles are moving determines how hot or cold the substance is.
Answer:DNA
Explanation:I already do the test
The net cell reaction for the iron-silver voltaic cell would be:
<span>3Ag+ + Fe --------> 3Ag + Fe3+
</span>
wherein it comes from the reaction of the cathode and the anode:
<span>Ag+ + e- -------> Ag, for the cathode and;
</span>
<span>Fe -------> Fe3+ + 3e-, for the anode
</span>
When both equations would be multiplied, the it would now yield the balanced net reaction as stated above.
Answer:
47.5 mL
Solving:
M1 = 4.00 M
V1 = ?
M2 = 0.760 M
V2 = 0.250 L
---
M1 * V1 = M2 * V2
V1 = ( M2 * V2 ) / M1
V1 = ( 0.760 * 0.250 ) / 4.00
V1 = ( 0.190 ) / 4.00
V1 = 0.0475 L
<u>Answer:</u> The volume of solution is 195.8 mL
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:
We are given:
Molarity of solution = 0.575 M
Given mass of nickel (II) acetate = 19.9 g
Molar mass of nickel (II) acetate = 176.8 g/mol
Putting values in above equation, we get:
To prepare 0.575 molar nickel (II) acetate solution, we need to add 19.9 grams of nickel (II) acetate to 195.8 mL of solution.
Hence, the volume of solution is 195.8 mL
