Answer:
1.08 grams of nitrogen
Explanation:
Thermally ammonium perchlorate dissociate as shown in figure.
Thus as per equation two moles of ammonium perchlorate will give four moles of water, two moles of oxygen, one mole of chlorine and one mole of nitrogen,
The molar mass of ammonium perchlorate = 117.5g/mol
Two moles of ammonium perchlorate = 2X 117.5 = 234 g
The molar mass of nitrogen = 28g
thus 234 grams of ammonium perchlorate will give 28 grams of nitrogen
Hence 9 grams of ammonium perchlorate will give 1.08 grams of nitrogen
Answer:
[H₃O⁺] = 6.31 x 10⁻³ M.
Explanation:
- To find the hydronium ion concentration [H₃O⁺], we can use the relation:
<em>pH = - log[H₃O⁺].</em>
<em></em>
∴ 2.2 = - log[H₃O⁺].
∴ log[H₃O⁺] = - 2.2
<em>∴ [H₃O⁺] = 6.31 x 10⁻³ M.</em>
Answer:
The measurements of the body resistance to acceleration by some external force is its ,B. inertial mass
Answer:
We know that there are two types of forces ,one is cohesive force between same molecule and other one is adhesive force between two different type of molecule.
In the water cohesive is more dominate than the adhesive force that is why it is for water molecule bond together.Another reason is that the hydrogen molecule have low electro negativity than the oxygen molecule that is oxygen molecule try to pull hydrogen and form the hydrogen bond.
