Explanation:
The density of sucrose is 1.58 g/ cm³
<em><u>Calculation</u></em>
Step 1 : calculate the volume of benzene
volume = mass/density
mass of benzene = total mass - mass of sucrose
=17.33 g - 9.35 g =7.98 g
volume = 7.98 / 0.879 =9.08 cm³
Step 2: calculate the volume of sucrose
volume of sucrose= Total volume - volume of benzene
Total volume = 15 ml =15 cm³
volume of sucrose is therefore = 15 cm³ - 9.08 cm³=5.92 cm³
Step 4: calculate the density of sucrose
density = mass/volume
= 9.35 g / 5.92 cm³ = 1.58 g/cm³
Answer:
Synthesis reaction:
Explanation:
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
A + B → AB
All other options are incorrect because,
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Combustion reaction:
In combustion reaction substances are react with oxygen and produces carbon dioxide and water.
Answer:
Depending on the anions and cations present within a hydrolysis reaction, the solution can be more... ... This lesson will explain how this occurs. ... that could react with water and create products that affect the characteristics of the solution.
Answer:
if you change the shape wouldn't it still have the same mass and volume because the density remains the same? so I think it is false
