When the volume of a gas is

Chemistry
1 answer:
Len [333]3 years ago
5 0

Initial temperature = -189.4  °C

<h3>Further explanation</h3>

Given

the volume of a gas is  changed from 3.6 L to 15.5 L

final temperature = 87 °C = 87+ 273 = 360 K

Required

initial temperature

Solution

Charles's Law

<em>When the gas pressure is kept constant, the gas volume is proportional to the temperature  </em>

\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

\tt T_1=\dfrac{V_1.T_2}{V_2}\\\\T_1=\dfrac{3.6\times 360}{15.5}\\\\T_1=83.6~K=-189.4^oC

What does the number of valence electrons determine?
N76 [4]

Valence electrons are the electrons in the outermost shell of an element on the periodic table. Atoms want to be able to have a full outer shell and they can share or trade electrons in order to achieve this. Valence electrons are also super super important in chemical reactions. The number of valence electrons determines what group that specific atom or element is in on the periodic table. This affects the reactivity of the element.

What mass of oxygen contains the same number of molecules as 42g of nitrogen?
lakkis [162]

Answer:

Given: 42 g of N2

Solve for O2 mass that contains the same number of molecules to 42 g of N2.

Solve for the number of moles in 42 g of N2

1 mole of N2 = (14 * 2) g = 28 g so the number of moles in 42 g of N2 is equal to 42 g / 28 g per mole = 1.5 moles

Solve for mass of 1 mole of oxygen

1 mole of O2 = 16 g * 2 = 32 g per mole

Solve for the mass of 1.5 moles of oxygen

mass of 1.5 moles of O2 = 32 g per mole * 1.5 moles

mass of 1.5 moles of O2 = 48 g

So 48 g of O2 contains the same number of molecules as 42 g of N2

Which of the following best defines insulator?
valkas [14]

C.) a substance with a low ability to conduct energy

Explanation:

The statement that best defines insulators is that it is a substance that has low ability to conduct energy.

Insulators resist the movement of mostly electrical and thermal energy.

They have unique properties that makes them so.

  • Insulators are substances that do not conduct heat and electricity.
  • Both their solid and molten form lacks the capability of electrical and thermal conduction.
  • Some substances can only conduct when molten or liquid.
  • Conductors are materials that allows for the passage of electrical and heat energy.
  • Most conductors are usually salts, ionic compounds and metals.
  • Non-conductors like insulators are usually plastics and woods.
