Based on the trend from the graph, the reaction time would have been 32.5 seconds.
<h3>What is the trend in the graph?</h3>
A trend is a general pattern which an observation follows based on previous observations and occurrences.
The reaction time is the time it take for a chemical reaction to occur.
Reaction time is also a measure of reaction rate. The shorter the reaction time, the faster the reaction rate and vice versa.
Based on the trend from the graph, the reaction time would have been 32.5 seconds.
In conclusion, reaction time is a measure of reaction rate.

Answer:
B
Explanation:
As you move from left to right, the number of protons increases. More protons means a bigger positive charge to pull in the electrons from the shells. This would then decrease the size of the atom.
Thus, the answer is B, the size decreases.
Hope this helps!
Fajans' Rules are used to predict whether a chemical bond will be covalent or ionic.
<span>This depends on: </span>
<span>- the charge on the cation </span>
<span>- the size of the cation </span>
<span>- the size of the anion </span>
The answer is <span>B) compound. hope it helps~!!!!!!!!!!!!!!!!!!:)</span>
Answer:
68000J/kg
Explanation:
Given parameters:
Mass of the substance = 0.5kg
Quantity of heat transferred to the body = 34000J
Unknown:
Specific latent heat of fusion = ?
Solution:
The specific latent heat is usually involve in phase changes;
H = mL
H is the quantity of heat supplied
m is the mass
L is the specific latent heat
Insert the parameters and solve;
34000 = 0.5 x L
L = 
= 68000J/kg
