Answer:
Explanation:
We can use Avogadro's Law: Equal volumes of gases under the same conditions of temperature and pressure contain the same number of molecules.
To say it another say, gases react in the same volume ratios as their coefficients in the balanced equation.
H₂ + Cl₂ ⟶ 2HCl
1 mol + 1 mol ⟶ 2 mol
1 L + 1 L ⟶ 2 L
Thus,
I’m stuck on the same thing
Answer:
Halogens
Explanation:
From the given choices, the halogens will have the smallest radius within the same period.
The size of an atom is estimated by the atomic radius. This is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state.
- Across a period in the periodic table, atomic radii decrease progressively from left to right.
- Down a group from top to bottom, atomic radii increase progressively due to the addition of successive shells.
Since halogen is the right most group from the choices given, it will have the smallest radius.
Moles of solute does not change.
Answer:
The correct answer is skeleton equation.
Explanation:
In chemistry, the skeletal formula of a compound is an abbreviated representation of its molecular structure. Skeleton formulas are used because they clearly show complicated structures, they are fast and simple to draw.
All atoms that are not carbon or hydrogen are represented by their chemical symbol. The relative amounts of reagents and products are not indicated.
Have a nice day!
