Plant cells are eukaryotic cells. Prokaryotic cells do not contain a membrane bound nucleus, mitochondria or other membrane bound cell structures (organelles), the DNA of prokaryotic cells are located in the cytoplasm of the cell. ... Plant cells are eukaryotic because they have a nuclear membrane.
so therefore, A rose thorn is a eukaryotic plant cell.

How many grams of sodium chloride decompose to yield 15 grams of chlorine gas?

defon

Answer:

24.6g of NaCl

Explanation:

Expression of the reaction:

2NaCl → 2Na + Cl₂

Given parameters:

Mass of Cl₂ = 15g

Unknown:

Mass of NaCl = ?

Solution:

To solve this problem, we have to use mole relationships.

Find the number of moles of the mass of the given specie;

Number of moles = $\frac{mass}{molar mass}$

Molar mass of Cl₂ = 2(35.5) = 71g/mol

Number of moles = $\frac{15}{71}$ = 0.21mole

Now;

From the balanced reaction equation;

1 mole of Cl₂ is produced from 2 moles of NaCl;

0.21 mole of Cl₂ will be produced from 0.21 x 2 = 0.42mole of NaCl

So,

Mass of NaCl = number of moles x molar mass

Molar mass of NaCl = 23 + 35.5 = 58.5g/mol

Mass of NaCl = 0.42 x 58.5 = 24.6g of NaCl
