2.5 km is the distance you can travel if a car gets 14 kilometers per liter and have 35 liters of gas.

Total distance traveled in 1 liter = 14 km

Total gas in the car = 35 liters

We have to find how much distance can be covered in in35 liters of gas.

Distance is the length of the path traveled between two points. It is the total movement of an object in a direction. It measures length.

Distance = 35/14

Or, distance = 2.5 km

Therefore, the total distance that can be covered by a car in 35 liters of gas is 2.5 km.

How many liters of 4.0 NaOH solution will react with 1.8 mol H2SO4

wlad13 [49]

Answer:

0.9 liters of 4.0 M NaOH solution will react with 1.8 moles of sulfuric acid.

Explanation:

$2NaOH(aq)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+2H_2O(l)$

According to reaction, 1 mole of sulfuric acid reacts with 2 moles of sodium hydroxide.

Then 1.8 moles of sulfuric acid will react with:

$\frac{2}{1}\times 1.8 mol=3.6 mol$ moles of NaOH.

Molarity of NaOH = 4.0 M

Moles of NaOH= n = 3.6 mol

Volume of NaOH = V

$M=\frac{n}{V(L)}$

$V=\frac{n}{M}=\frac{3.6 mol}{4.0 M}=0.9 L$

0.9 liters of 4.0 M NaOH solution will react with 1.8 moles of sulfuric acid.

1. The volume of a gas is 10.0 liters and its temperature is 1500 K. If the temperature is

cupoosta [38]

Answer:

5 L

Explanation:

So this problem refers to Charles's law. You would use this formula..

$\frac{V_{I} }{T_{I} } = \frac{V_{F} }{T_{F} }$ (Initial volume / Initial Temperature) = (Final volume / Final Temperature)

For your problem, it would look like this...

$\frac{10L}{1500k} = \frac{V_{F} }{750k}$

You would cross multiply and your answer would be 5L.

To reassure yourself that the answer is correct, Charles law states that the Volume and the Temperature are directly proportional. Meaning if your temperature is decreasing, your volume <u>has</u> to decrease.

You can obtain a rough estimate of the size of a molecule with the following simple experiment: Let a droplet of oil spread out

mina [271]

Answer:

The diameter of the oil molecule is $4.4674\times 10^{-8} cm$ .

Explanation:

Mass of the oil drop = $m=9.00\times 10^{-7} kg$

Density of the oil drop = $d=918 kg/m^3$

Volume of the oil drop: v

$d=\frac{m}{v}$

$v=\frac{m}{d}=\frac{9.00\times 10^{-7} kg}{918 kg/m^3}$

Thickness of the oil drop is 1 molecule thick.So, let the thickness of the drop or diameter of the molecule be x.

Radius of the oil drop on the water surface,r = 41.8 cm = 0.418 m

1 cm = 0.01 m

Surface of the sphere is given as: a = $4\pi r^2$

$a=4\times 3.14\times (0.418 m)^2=2.1945 m^2$

Volume of the oil drop = v = Area × thickness

$\frac{9.00\times 10^{-7} kg}{918 kg/m^3}=2.1945 m^2\times x$

$x= 4.4674\times 10^{-10} m= 4.4674\times 10^{-8} cm$

The thickness of the oil drop is $4.4674\times 10^{-8} cm$ and so is the diameter of the molecule.

What is the difference between an atom and an element?

Travka [436]

Answer:

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom

Explanation:

so In simple terms an atom contains Protons and Electrons and can be found in an Element, but an element comprises of atoms which come together to form up that particular Element
