Answer:
A. Molecules have finite volume.
Explanation:
Gases deviate from the ideal gas law at high pressures because its molecules have a finite volume.
Real gases have a finite volume which enables more interaction between the molecules while ideal gases are assumed not to have a finite volume or occupy space which is why it lacks any form of interaction between its molecules.
This difference is the deviation between the real and ideal gases.
Answer:
K = 0,00000135 = 1.35 * 10^-6
Explanation:
Step 1: Data given
The equilibrium constant, K, for any reaction is defined as the concentrations of the products raised by their coefficients divided by the concentrations of the reactants raised by their coefficients. In this case, the concentrations are given as partial pressures.
The partial pressures of H2O = 0.0500 atm
The partial pressures of H2 = 0.00150 atm
The partial pressures of O2 = 0.00150 atm
Step 2: The balanced equation
2H2O(g) ⇆ 2H2(g) + O2(g)
Step 3: Calculate K
K = [O2][H2]² / [H2O]²
K = 0.00150 * 0.00150² / 0.0500²
K = 0,00000135 = 1.35 * 10^-6
Energy from a light source is known as radiation.
Answer:
Mass = 15600 g
Explanation:
Given data:
Number of atoms of oxygen = 5.87 × 10²⁶
Mass of oxygen = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
5.87 × 10²⁶ atom × 1 mole / 6.022 × 10²³ atom
0.975 × 10³ mole
975 mole
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 975 × 16 g/mol
Mass = 15600 g
Dimensional analysis:
5.87 × 10²⁶ atom × 1 mol/6.022 × 10²³ atom × 16 g/ 1 mol = 15600 g
I don't agree because ocean temperatures can get warm thanks to high sun temperature and warm fronts.
