Answer:

mass(m)=26.4g

volume (v)=3.0cm²

we have

density =m/v=26.4/3=8.8g/cm³

since it is equal to density of nickel.

<u>Option C nickel</u> is a required answer.

_____ is a gel-like substance enclosed by the cell membrane that contains the cell's organelles. A) chloroplast B) cytoplasm C)
stepan [7]

Answer: The correct answer for the blank is-

B) cytoplasm.

Cytoplasm is the fluid filled compartment ( a thick, gel like substance) within the cell of a living organism that is mainly composed of water, salts, and proteins. It is surrounded by the cell membrane ( plasma membrane) and contains all the parts of cell ( such as in eukaryotic cell, it contains all the cell organelles except nucleus). It is the site for all the essential cellular processes.

Thus, option B) is the right answer.

How many grams of calcium chloride will be produced when 29.0 g of calcium carbonate is combined with 15.0 g of hydrochloric aci
horsena [70]

Answer:

22.7 g of CaCl₂ are produced in the reaction

Explanation:

This is the reaction:

CaCO₃ +  2HCl  →  CaCl₂  + CO₂  +  H₂O

Now, let's determine the limiting reactant.

Let's divide the mass between the molar mass, to find out moles of each reactant.

29 g / 100.08 g/m = 0.289 of carbonate

15 g / 36.45 g/m = 0.411 of acid

1 mol of carbonate must react with 2 moles of acid

0.289 moles of carbonate will react with the double of moles (0.578)

I only have 0.411 of HCl, so the acid is the limiting reactant.

Ratio is 2:1, so I will produce the half of moles, of salt.

0.411 / 2 = 0.205 moles of CaCl₂

Mol . molar mass = mass → 0.205 m . 110.98 g/m = 22.7 g

Why is it permissible to use a wet bottle when first obtaining your kmno4 solution?
Murrr4er [49]
For the answer to the question above, well presumably because the exact concentration of the composition KMnO4 solution doesn't matter. <span>If the concentration of the KMnO4 solution is important (usually in titrations etc.) then it is not allowed to use a wet bottle. The water in the bottle will dilute the KMnO4 solution and change the concentration of the said compound.</span>
