What volume is indicated on the graduated cylinder?

Chemistry
1 answer:
nlexa [21]3 years ago
3 0
To find the volume of an object with a graduated cylinder:
Take the graduated cylinder and fill it with water to a certain level.

Place the object you are trying to measure in the cylinder.

The level of water will rise to a certain point.

The level of water with the object in it minus the original level will give you the volume.

To just measure the volume of a liquid in the cylinder:
Pour the amount of liquid into the cylinder

Have the cylinder on a flat surface and look at the level of liquid at eye level

The volume of liquid will be where the bottom of the curve of the liquid level is. Look at the unit measurement and that will give you the unit of volume.

If this is what what it was asking I’m sorry

Compare the solubility of silver iodide in each of the following aqueous solutions:
Semenov [28]

Answer:

Compare the solubility of silver iodide in each of the following aqueous solutions:

a. 0.10 M AgCH3COO

b. 0.10 M NaI

c. 0.10 M KCH3COO

d. 0.10 M NH4NO3

1. More soluble than in pure water.

2. Similar solubility as in pure water.

3. Less soluble than in pure water.

Explanation:

This can be explained based on common ion effect.

According to common ion effect the solubility of a sparingly soluble salt decreases further in a solution which has a common ion to it.

The solubility of AgI(s) silver iodide in water is shown below:

AgI(s)  Ag^{+}(aq)+I^{-}(aq)\\

a. a. 0.10 M AgCH3COO has a common ion Ag+ with AgI.

So, AgI is less soluble than in pure water in this solution.

b. 0.10 M NaI has a common ion I- with AgI.

So, AgI is less soluble than in pure water in this solution.

c. 0.10 M KCH3COO:

This solution has no common ion with AgI.

So, AgI has similar solubility as in pure water.

d. 0.10 M NH4NO3:

In this solution, AgI can be more soluble than in pure water.

What is the percent yield for the reaction below when
kumpel [21]

Answer:

Percent yield of reaction is<em> 150%.</em>

Explanation:

Given data:

Percent yield = ?

Actual yield of SO₃ = 586.0 g

Mass of SO₂ = 705.0 g

Mass of O₂ = 80.0 g

Solution:

Chemical equation:

2SO₂ + O₂      →     2SO₃

Number of moles of SO₂:

Number of moles = mass/ molar mass

Number of moles = 586.0 g/ 64.1 g/mol

Number of moles = 9.1 mol

Number of moles of O₂:

Number of moles = mass/ molar mass

Number of moles = 80.0 g/ 32g/mol

Number of moles = 2.5 mol

Now we will compare the mole of SO₃ with O₂ and SO₂.

                      SO₂          :          SO₃

                        2             :            2

                     9.1              :           9.1

                       O₂            :          SO₃

                        1              :            2

                     2.5             :           2×2.5 = 5

The number of moles of SO₃ produced by oxygen are less it will limiting reactant.

Theoretical yield of SO₃:

Mass = number of moles × molar mass

Mass = 5 mol × 80.1 g/mol

Mass = 400.5 g

Percent yield of reaction:

Percent yield = actual yield / theoretical yield  × 100

Percent yield = 586.0 g/ 400.5 g× 100

Percent yield = 1.5× 100

Percent yield = 150%

A solution with a ph of 2 has a h+ ion concentration that is _____ than a solution with a ph of 4
RoseWind [281]
A  solution with  a Ph  of   2  has  a  H+  ion  concentration  that  is two  times  greater  than  a  solution  with  a  ph  of  4.      The  Ph  of  2  and 4 indicate  that  the  solution  is   acidic since  they  are  less  than  PH  of  7. The  H+   ions  are more present   when  the  solution is  acidic  but   the  Ph  differ  with  concentration  H+  ions. The  solution  with  a  Ph  of  2  has  more  H+    than  the  solution  with  Ph  of  4  thus  the  solution with Ph  of  2  has  more  hydrogen  ions  than  that  of  4
