am not sure i understand but i think it got more chlorophyll
Answer:
297.23 K
Explanation:
Given that:
the mass of the gold nugget (m) = 376 g
the initial temperature
= 398 K
amount of heat lost Q = -4.85 kJ = -4.85 × 10³
specific heat capacity (c) = 0.128 J/g° C
Using the formula for calculating the Heat energy


Answer: C - B - A - D
Explanation:
-Obtain a flask that is thoroughly cleaned
-Add the desired amount of stock solution
-Add deionized water until the volume reaches the mark on the flask.
- Cap the flask and invert several times to thoroughly mix the solution.
B. 11,540
<h3>Further explanation
</h3>
The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually radioactive elements have an unstable atomic nucleus.
General formulas used in decay:

T = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
Nt=25 g
No=100 g
t1/2=5770 years
