nalin [4]3 years ago
7 0

Answer:

Explanation:

The molecular mass of C2H6 is approximately 30 or [(2 x 12) + (6 x 1)]. Therefore the molecule is about 2.5 times as heavy as the 12C atom or about the same mass as the NO atom with a molecular mass of 30 or (14+16).

Why is the law of conservation of mass law and not a theory?
Elodia [21]

Answer:

In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Explanation:

That is what I think on the subject

Photo 1: Chemical Equation for Redox of Copper and Silver Nitrate. Note: Copper has a 2 oxidation number in the products.Silver
Mekhanik [1.2K]

The copper atom is oxidized while the silver is reduced.

<h3>What is a redox reaction?</h3>

A redox reaction is one that occurs between an oxidizing agent and a reducing agent. One specie is oxidized while the other specie is reduced in the reaction.

In this case, the oxidizing agent is the silver and the reducing agent is the copper atom. The copper atom is oxidized while the silver is reduced.

The complete equation is;

Cu(s) + 2AgNO3(aq) -----> Cu(NO3)2(aq) + Ag(s)

Ionically;

Cu(s) + 2Ag^+ -----> Cu^2+(aq) + Ag(s)

Draw the Lewis structure for sulfur tetrafluoride, SF4
Vlad [161]

Notes:-

  • S has Z=16

Electronic configuration

  • 1s²2s²2p⁶3s²3p⁴

So

  • Valency is 4 and 6

  • Three fluorine atoms take 3 electrons and one lone pair present over S
  • As one electron remains unshared so we use + sign .

Boyle's Law represents the relationship of volume as pressure is changed. The constants of Boyle's Law are
Katena32 [7]

Answer:

temperature and number of molecules of gas

Explanation:

Boyle's law is one of the gas laws, which states that the volume of a gas is inversely proportional to the pressure at a constant temperature. The Boyle's law equation is given as follows:

P ∝ (1/V)

P = K/V

PV = K

Based on these, the temperature of an ideal gas and the number of molecules in the gas are kept constant in Boyle's law.
