Answer:
The final temperature of the mixture is closest to 30ºC
Explanation:
<u>Step 1:</u> Data given
Volume of sample 1 = 30 mL ≈ 30 grams
Temperature of sample 1 = 10 °C
Volume of sample 2 = 50 mL ≈ 50 grams
Temperature of sample 2 = 50 °C
Step 2: Calculate the final temperature
T(final) = (30 g * 10 °C + 50 g * 50 °C) / (50 g + 30 g)
T(final) = (300 + 2500)/80
T(final) = 35 °C
The final temperature of the mixture is closest to30ºC
The atoms that are the same element are atoms 1 and 2, because they have the same number of protons (option D).
<h3>What is an element?</h3>
Element is one of the simplest chemical substances that cannot be decomposed in a chemical reaction or by any chemical means and made up of atoms all having the same number of protons.
The atoms of an element have the same number of protons, which is the atomic number.
According to the table given above, three atoms and their respective proton, electron and neutron number are given.
It can be said that atoms 1 and 2 are of the same element, because they have the same number of protons.
