Butane: It is an organic compound belongs to class of alkane having molecular formula .
Butane consist of four carbon and ten hydrogen atoms attached by single covalent bond. Carbon and hydrogen atoms are attached in such a way that the valency of carbon that is four and valency of hydrogen that is one is completely satisfied and thus, results in the formation of stable compound.
The structure of butane with hydrogen atoms is shown in the image.
Answer:
A
Explanation:
Cuz the when you pair Li and Cl, it becomes LiCl (it has 1:1 ratio)
The answer to this question would be <span>na2so4.
Most of the metal on the first and second columns of the chemical table would have high water solubility. Silver(Ag) and iron(Fe) is a molecule that belongs to transition metal group, which did not have high solubility in the water. Na2SO4 would be the one with highest water solubility</span>
Sugar dissolving in warm water is an example of physical change.
physical change is doesn't alter the composition or the identity of the substance .
That's mean when you dissolves sugar in water, after a while the object will be the same which mean that the component doesn't change
Answer:
15.0 µm
Step-by-step explanation:
Density = mass/volume
D = m/V Multiply each side by V
DV = m Divide each side by D
V = m/D
Data:
m = 1.091 g
D = 7.28 g/cm³
l = 10.0 cm
w = 10.0 cm
Calculation:
<em>(a) Volume of foil
</em>
V = 1.091 g × (1 cm³/7.28 g)
= 0.1499 cm³
(b) <em>Thickness of foil
</em>
The foil is a rectangular solid.
V = lwh Divide each side by lw
h = V/(lw)
= 0.1499/(10 × 10)
= 1.50 × 10⁻³ cm Convert to millimetres
= 0.015 mm Convert to micrometres
= 15.0 µm
The foil is 15.0 µm thick.
