If the mass of an object stays the same but its volume decreases, will the density increase or decrease?

Chemistry
1 answer:
fiasKO [112]4 years ago
4 0

Answer:

Increase

Explanation:

Density = Mass ÷ Volume

Let the mass be 100 for instance and the original volume to be 4.

100 ÷ 4 = 25

The new volume let it be 2.

100 ÷ 2 = 50

50 is more than 25 so the density increases

Which of the following concepts is shared by quantum theory and the Bohr model?
klasskru [66]

Electrons move about the nucleus in defined orbits.

Explanation:

The Bohr mode of the atom was established based on the quantum mechanics originally developed by Planck.

  • He suggested that the extranuclear part of the atom consists of electrons in specific spherical orbits around the nucleus. The orbits represents the principal energy levels.

The quantum theory was developed originally by Planck.

  • He suggested energy exists in form of packets and discrete amount and not in form of flow like waves.

The quantum theory and Bohr mode in this regard as they both agree that electrons and energy are both quantized.

Kc is 1.67 x 10^20 at 25 °C for the formation of iron(III) oxalate complex ion:
Liula [17]

Answer:

n_{C_2O_4^{2-}}=1.59mol C_2O_4^{2-}

Explanation:

Hello there!

In this case, according to the given information and chemical equation, it turns out possible for us to calculate the moles of C2O4^2- by firstly setting up the equilibrium expression:

Kc=\frac{[[Fe(C_2O_4)_3]^{3-}]}{[Fe^{3+}][C_2O_4^{2-}]^3}

However, according to the question, we just need to apply the given 1:3 mole ratio in the chemical reaction, of iron (III) ions to oxalate ions to obtain:

n_{C_2O_4^{2-}}=0.53molFe^{3+}*\frac{3molC_2O_4^{2-}}{1molFe^{3+}}=1.59mol C_2O_4^{2-}

Regards!
