Answer:
1.4200 g
Explanation:
The chlorine gas has a molecular formula Cl2. In table periodic, the molar mass of one atom of chlorine is 35.5 g/mol, so the molar mass of Cl2 is 71 g/mol.
Molar mass, mass and number of moles are related by the equation below:
Where n is the number of moles, m is the mass, and MM is the molar mass of the compound.
So, for 0.0200 moles of Cl2 produced:
m = 71x0.0200
m = 1.4200
The answer to this question is Contact
depending on the geological event that put into place, this will have a specific semantic value.
A contact usually represented by different kind of lines on the geological map and usually use to determine <span>where rocks come into contact across fault zones</span>
Q=44.0 ct
p=3.51 g/cm³
Δq=0.200 g/ct
m=q×Δq
v=m/p=q×Δq/p
v=44.0×0.200/3.51≈2.5 cm³
C. 2.5 cm³
Answer:Chemical properties such as its ability to form chemical bonds
Explanation:
The group to which an element belong is known by the number of electrons on its outermost shell. Since chemical reactions often involve valence electrons of an atom, the number of outermost shell electrons give us an idea of the chemical properties, reactivity and readiness of the element to form chemical bonds. The number of electrons in the outermost shell is the most succinct description of the chemical disposition of any atom.
