If 37.5 ml of .100m calcium chloride reacts completely with aqueous silver nitrate, what is the mass of agcl precipitate

Chemistry

Lelu [443]3 years ago

The equation is given as follows  
2AgNO3 + CaCl2 yields 2AgCl + Ca(NO3)2 
Since the molarity, M, is equal to the number of moles of solute, n, divided by the volume of the solution, V. It follows from the equation that the number of moles of Cacl2 = 37.5 * .100 * 10^(-3) = 0.00375 moles.  
1 mole of Cacl2 yields 2 moles of Agcl2 
0.00375 moles of Cacl2 will yield X.  
So X = 0.00375 * 2/1 = 0.0075 moles.  
No of moles of Agcl2 = mass /molar mass.  
Molar mass of Agcl = 178.772 
So mass = 178.772 * 0.0075 = 1.34079

What is the movement of water up a narrow tube due to attractions with the surface of the tube called? capillary action meniscus
Shtirlitz [24]

The attraction mediated flow of water in the narrow tube has been termed as Capillary action. Thus, option A is correct.

The process of flowing up of liquid with the attraction force between the molecules and the surface has been achieved with the surface characteristics.

<h3>Movement of water in a narrow tube</h3>

The surface has the force of attraction with the flowing liquids in the sample. It results in the increased surface interaction, and the liquid flows up in the tube against gravity.

The movement of the liquid in the water through a narrow tube has been termed as capillary action. Thus, option A is correct.

Carbon dioxide (CO2) is a gas at room temperature and pressure. However, carbon dioxide can be put under pressure to become a "s
Lunna [17]

Answer:

The mass of this 25 mL supercritical CO2 sample has a mass of 11.7g

Explanation:

Step 1: Given data

The supercritical CO2 has a density of 0.469 g/cm³ (or 0.469 g/mL)

The sample hasa volume of 25.0 mL

Step 2: Calculating mass of the sample

The density is the mass per amount of volume

0.469g/cm³ = 0.469g/ml

The mass for a sample of 25.0 mL = 0.469g/mL * 25.0 mL = 11.725g ≈ 11.7g

The mass of this 25 mL supercritical CO2 sample has a mass of 11.7g

An organic compound, which has the empirical formula C12H25 has an approximate molar mass of 338 g/mol. What is its probable mol
Marta_Voda [28]

Answer:

C24H50

Explanation:

The empirical fomula's molar mass is 169.25 g/mol.

We know the molecular formula's molar mass is 338 g/mol.

338/169.25= 1.99 or approximately 2
