A gas occupies 12.5 ft at - 173 °C. At what Celsius temperature will its volume be 16.0

Chemistry

Elza [17]3 years ago

Answer:

T₂ = 128.19 K

Explanation:

Given that,

The initial volume, V₁ = 12.5 ft³

Initial temperature, T₁ = -173 °C = 100.15 K

Final volume, V₂ = 16 ft³

We need to find the new temperature. The relation between temperature and volume is given by :

V\propto T\\\\\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}

Put all the values,

T_2=\dfrac{T_1V_2}{V_1}\\\\T_2=\dfrac{100.15\times 16}{12.5}\\\\T_2=128.19\ K

So, the new temperature is 128.19 K.

How many moles of copper (Cu) are in 65.8 g Cu?
Veseljchak [2.6K]
<h2><u>Answer:</u></h2>

The correct answer is A) 1.04 mol Cu

{65.8 g     /   63.55 g/mol}

= 1.04 mol Cu

Explanation:

In  63.55  g  of copper metal there are  1 m o l  of  C u  atoms. By dividing the mass of Cu and molar mass, we can easily get the number of moles.

A titration of 0.1 M NaOH into 1.2 L of HCl was stopped once the pH reached 7 (at 25C). If 0.4 L of NaOH needed to be added to a
MArishka [77]

Answer:

0.033 M

Explanation:

Let's consider the neutralization reaction between NaOH and HCl.

NaOH + HCl → NaCl + H₂O

0.4 L of 0.1 M NaOH were used. The reacting moles of NaOH are:

0.4 L × 0.1 mol/L = 0.04 mol

The molar ratio of NaOH to HCl is 1:1. The reacting moles of HCl are 0.04 moles.

0.04 moles of HCl are in 1.2 L. The molarity of HCl is:

M = 0.04 mol / 1.2 L = 0.033 M

What force types change the direction of motion
lora16 [44]

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity. Let’s say an object is moving along a table on earth, suddenly the finite table ends, resulting in the object being present in the air, which means there is no normal contact force N to combat the force by gravity mg, which is why there is an acceleration downwards. This proves as a projectile motion since the direction of motion start changing from horizontal to vertical. Another example is one throwing an object up. It moves up and slows down, reaching its maximum point, leading to it starting to move downwards. This too is a change in motion.
