Zolol [24]3 years ago
4 0
For the given question above, <span>Polyethylene Terephthalate (PET) is a resin of a polyester family making it an organic molecule. Its density is 1.40 g/cm³. The other choices are water (density of 1.00 g/cm³), seawater (1.025 g/cm³), and hot water (less than 1.00 g/cm³). Being that PET is the most dense in relation to the three aforementioned liquids, it would not float atop any. I hope this helps.</span>

If 25 mL of a HCl solution of unknown concentration was neutralized with 10 mL of a 0.30 M NaOH solution, what was the original
QveST [7]

Answer:

0.12 M

Explanation:

Step 1: Write the balanced equation

NaOH + HCl ⇒ NaCl + H₂O

Step 2: Calculate the reacting moles of NaOH

10 mL of a 0.30 M NaOH solution react.

0.010L \times \frac{0.30mol}{L} = 3.0 \times 10^{-3} mol

Step 3: Calculate the reacting moles of HCl

The molar ratio of NaOH to HCl is 1:1. The reacting moles of HCl are 1/1 × 3.0 × 10⁻³ mol = 3.0 × 10⁻³ mol.

Step 4: Calculate the concentration of HCl

3.0 × 10⁻³ mol of HCl are in 25 mL of solution.

M = \frac{3.0 \times 10^{-3} mol}{0.025L} = 0.12 M

What does h20 mean on the periodic elements chart
Paladinen [302]

Answer:

The compound, H₂O, will not be found on the periodic table. This is because the periodic table only consists of individual elements. That being said, the elements found within H₂O are located on the periodic table. H₂O consists of hydrogen, denoted by the symbol "H", and oxygen, denoted by the symbol "O". The subscript (the 2) tells us that there are 2 hydrogen atoms located in the H₂O molecule.

Hydrogen is the first element listed on the periodic table and can be found in the top leftmost position. Oxygen is the eighth element on the periodic able and is located in the second row at the top right.
