Answer:
the proton and the neutron
Explanation:
mass of The proton is approximately 1.6726 × 10^-27 Kg
mass of the electron is approximately 9.109 × 10^-31 Kg
mass of the neutron is approximately 1.6749 × 10^-27 Kg
Here we see that mass of proton and neutron is approximately similar.
_____________________________________________
Lets see what is the mass of these particle IN atm unit
mass of these particles can also be described in form of amu(atomic mass unit)
1 atm is the mass defined as 1/12 th of mass of the carbon-12(c-12) atom.
In terms of unit atm
mass of proton = 1 amu
mass of electron = 5.45 × 10−4 amu
mass of neutron = 1 amu
hence we can say that mass of proton = mass of neutron.
mass of atom is sum of mass of all the neutron and proton in the atom.
Hence, mass of neturon and atom cannot be equal.
This makes option four the neutron and the atom , the wrong choice.
correct answer is the proton and the neutron
therefore, An atom contains one proton , one electron and one neutron then, mass of proton is similar in mass of neutron.
A. The balanced chemical reaction of Sodium metal and Water is 2Na + 2H₂O → 2NaOH + H₂.
<h3>What is a balanced chemical equation? </h3>
A balanced equation contains the same number of each type of atoms on both the left and right sides of the reaction arrow.
<h3>Reaction of Sodium metal and Water</h3>
Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2).
The balanced chemical reaction is written below;
2Na + 2H₂O → 2NaOH + H₂
Thus, the balanced chemical reaction of Sodium metal and Water is 2Na + 2H₂O → 2NaOH + H₂.

<u>Analysing the Question:</u>
We are given the balanced equation:
C₆H₁₂O₆ + 6O₂→ 6CO₂ + 6H₂O
from this equation, we can say that: <em>for every 1 mole of Glucose, we need 6 moles of Oxygen</em>
<u>Moles of Glucose used in the reaction:</u>
Molar mass of Glucose = 180 grams / mol
Given mass of Glucose = 1 gram
Mole of Glucose = Given mass / Molar mass
Moles of Glucose = 1 / 180 moles
<u>Mass of Oxygen required:</u>
We know that for every mole of Glucose, we need 6 moles of Oxygen
So, for 1/180 moles of Glucose, we need 6 / 180 = 1 / 30 moles of Oxygen
Mass of 1 / 30 moles of Oxygen:
Mass = Molar mass * number of moles
Mass of Oxygen = 32 * 1/30
Mass of Oxygen = 32 / 30
Mass of Oxygen = 1.06 grams
Answer:
b. mercury
Explanation:
Fishes and some other sea foods are are known to concentrate mercury in their bodies. Consumption of these products gradually accumulate mercury in the body over time.
More specifically, fishes like swordfish, king mackerel and shark are known to concentrate higher amount of mercury than other species of fishes. Hence, limiting their consumption will protect humans from mercury poisoning.
The correct option is b.
