Answer:
a > c > b
Explanation:
As higher is the strength and stiffness of the bond between two atoms, more stable it is, and more difficult is to these bonds vibrate. So, the stretching vibration decreases when the strength and stiffness increases.
As more bonds are done between the atoms, more strength, and stiffness they have. So, the order of increase is:
simple bond > double bond > triple bond
And the increased frequency of vibration is:
triple bond > double bond > simple bond
An alkane is a hydrocarbon that has only simple bonds between carbons, an alkene is a hydrocarbon with one double bond between carbon, and an alkyne is a hydrocarbon with one triple bond. So, the increase in vibration of them is:
alkyne (a) > alkene (c) > alkane (b)
Answer and Explanation:
It is not necessary to know the amount of salt in the aqua, because we know that the presence of salt in the water will increase its density.
In this case, salt increases the mass of the water, without increasing the volume of water. as the egg will not change in volume or water, we know that the density of the egg will be constant, while the change in the mass of the water with the addition of salt, will change the density of the water which will increase progressively until it becomes denser than the egg and, consequently, it will not let the egg sink.
Answer:
Number 6 is correct all substances are made of molecules.
Explanation:
A molecule is a formation of atoms or a chemical and all substances are made of chemicals.
Se would be the answer I think. Hop this helped!
Answer:
CaCO3 + 2HCl = CaCl2 + CO2 + H2O
Explanation:
CaCO3 + HCl = CaCl2 + CO2 + H2O
Error in equation should be HCl on left hand side not HC
Left Side
Ca = 1
C = 1
O = 3
H = 1
Cl = 1
Right Side
Ca = 1
C = 1
O = 3
H = 2
Cl = 2
So we'll try and balance the Chlorine
CaCO3 + 2HCl = CaCl2 + CO2 + H2O
Left Side
Ca = 1
C = 1
O = 3
H = 2
Cl = 2
Right Side
Ca = 1
C = 1
O = 3
H = 2
Cl = 2
Yay it worked
