A chemist has two large containers of sulfuric acid solution, with different concentrations of acid in each container. Blending

310 mL of the first solution and 590 mL of the second gives a mixture that is 11.58% acid, whereas blending 85 mL of the first mixed with 490 mL of the second gives a 7.25% acid mixture. What are the concentrations of sulfuric acid in the original containers?

6.<br> What is the acceleration of a 24 kg mass pushed by a 6 N force?<br> I jus need number 6
Setler79 [48]

The acceleration : 0.25 m/s²

<h3>Further explanation</h3>

Given

mass = m = 24 kg

Force = F = 6 N

Required

The acceleration

Solution

Newtons' second law :

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object

ΣF =  m x a

\large {\boxed {\bold {a = \frac {\sum F} {m}}}

Input the value :

6 N = 24 kg x a

a = 6 : 24

a = 0.25 m/s²

How much energy is released when 0.40 mol C6H6(g) completely reacts with oxygen?
Vsevolod [243]
 <span>This question asksyou to apply Hess's law. 
You have to look for how to add up all the reaction so that you get the net equation as the combustion for benzene. The net reaction should look something like C6H6(l)+ O2 (g)-->CO2(g) +H2O(l). So, you need to add up the reaction in a way so that you can cancel H2 and C. 
multiply 2 H2(g) + O2 (g) --> 2H2O(l) delta H= -572 kJ by 3 
multiply C(s) + O2(g) --> CO2(g) delta H= -394 kJ by 12 
multiply 6C(s) + 3 H2(g) --> C6H6(l) delta H= +49 kJ by 2 after reversing the equation. 
Then, 
6 H2(g) + 3O2 (g) --> 6H2O(l) delta H= -1716 kJ 
12C(s) + 12O2(g) --> 12CO2(g) delta H= -4728 kJ 
2C6H6(l) --> 12 C(s) + 6 H2(g) delta H= - 98 kJ 
______________________________________... 
2C6H6(l) + 16O2 (g)-->12CO2(g) + 6H2O(l) delta H= - 6542 kJ 
I hope this helps and my answer is right.</span>

The density of a certain type of plastic is 0.81 g/cm3. If a sheet of this plastic is 10.0 m long, 1.0 m wide, and 1 cm thick, w
crimeas [40]

<u>Answer:</u> The mass of plastic sheet is 8.1\times 10^4g

<u>Explanation:</u>

The plastic sheet is in the form of cuboid. To calculate the volume of cuboid, we use the equation:

V=lbh

where,

V = volume of cuboid

l = length of cuboid = 10.0 m = 1000 cm     (Conversion factor: 1 m = 100 cm)

b = breadth of cuboid = 1.0 m = 100 cm

h = height of cuboid = 1 cm

Putting values in above equation, we get:

V=1000\times 100\times 1=10^5cm^3

To calculate mass of a substance, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

We are given:

Density of plastic sheet = 0.81g/cm^3

Volume of plastic sheet = 10^5cm^3

Putting values in equation 1, we get:

0.81g/cm^3=\frac{\text{Mass of plastic sheet}}{10^5cm^3}\\\\\text{Mass of plastic sheet}=8.1\times 10^4g

Hence, the mass of plastic sheet is 8.1\times 10^4g
