Homo neanderthalensis, Homo Denisovanus.
The answer is habitat because the organisms go to there habitat
Element in the halogen family react easily with other elements whose atom can give up electrons. akali metals loses one electrons they are left with zero valence electrons and they become more chemically stable. hope that helps

Answer:</h3>
The total mass of sodium chloride and water formed is greater than 35 grams.
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of HCl as 18 g
- Mass of NaOH as 20 g
In this case, HCl will react with NaOH to form salt and water.
- The equation for the reaction is;
HCl(aq) + NaOH(aq) → H₂O(l) + NaCl(aq)
- We are going to first determine the rate limiting reactant
Moles of HCl = 18 g ÷ 26.46 g/mol
= 0.68 moles
Moles of NaOH = 20 g ÷ 40.0 g/mol
= 0.5 moles
- From the equation 1 mole of HCl reacts with 1 mole of NaOH
Therefore;
- NaOH is the rate limiting reactant and HCl is in excess
Now, we can determine the amount of H₂O and NaCl
- 1 mole of NaOH reacts to produce 1 mole of H₂O and 1 mole of NaCl
Therefore;
- Moles of NaOH = moles of water = moles of NaCl
Thus;
Moles of NaCl = 0.5 moles
Moles of H₂O = 0.5 moles
But, mass = moles × molar mass
Mass of water = 0.5 moles × 18.02 g/mol
= 9.01 g
Mass of NaCl = 0.5 moles × 58.44 g/mol
= 29.22 g
Thus, the total mass of water and NaCl is 38.23 g
Therefore, the correct answer is, the total mass of sodium chloride and water formed is greater than 35 grams.
