Answer:
A is the right answer
Explanation:
In double replacement reaction two compounds combines to give other two compounds
As example:
CaCl2 + 2AgNO3 = Ca(NO3)2+ 2AgCl
Answer:
nonrenewable
Explanation:
It's just an educated guess but you know plastic bottles and stuff like that contribute to pollution
Answer:
n=17.85 moles
Explanation:
Given mass is, m = 1.5 kg = 1500 g
The molar mass of sodium bicarbonate is, M = 84.007 g/mol
We need to find the no of moles in 1.5 kg of Sodium bicarbonate . We know that, no of moles is equal to given mass divided by molar mass.
<h2>
So, there are 17.85 moles in 1.5 kg of Sodium bicarbonate.</h2>
The gas, 2 mol of H2, occupies the highest volume at STP since at STP the volume of this gas is approximately 44.8 mol as compared to other options this has the greatest amount.
Answer:
Electrostatic Van de Waals forces act between molecules to form weak bonds. The types of Van der Waals forces, strongest to weakest, are dipole-dipole forces, dipole-induced dipole forces and the London dispersion forces. The hydrogen bond is based on a type of dipole-dipole force that is especially powerful. These forces help determine the physical characteristics of materials.
