Answer:
There is one nitrate ion in the products, and two in the reactants of this equation.
Explanation:
1: We know a nitrate ion has the formula
, so we just need to count how many of them are on each side of the equation.
2: To find how many are in the reactants of the equation, you look at the left hand side (before the arrow). You can see the section
, which shows that there are two nitrate ions in the reactant side (as seen by the little 2).
3: To find how many are on the products side, you do the same thing - this time there is only one
in the lithium nitrate.
So, there is one nitrate ion in the products, and two in the reactants of this equation.
Answer: None of the above statements is false.
Explanation:
In a solid substance, particles are closely held together due to which a solid substance has definite shape and volume. Therefore, solids are also incompressible in nature.
In liquids, the molecules are slightly away from each other due to which they can slide past each other. Hence, liquids do not have a fixed shape but they have a definite volume. Liquids are also incompressible in nature.
In gases, the particles are held by Vander waal forces due to which they move rapidly from one place to another. Hence, gases are highly compressible in nature.
Thus, we can conclude that none of the given statements are false.
Answer:
Equal parts are needed to make glucose and oxygen. The excess oxygen is released into the air
Explanation:
This equation explains why having plants in your house is good.
<h3><u>Answer</u>;</h3>
= 226 Liters of oxygen
<h3><u>Explanation</u>;</h3>
We use the equation;
LiClO4 (s) → 2O2 (g) + LiCl, to get the moles of oxygen;
Moles of LiClO4;
(500 g LiClO4) / (106.3916 g LiClO4/mol)
= 4.6996 moles
Moles of oxygen;
But, for every 1 mol LiClO4, two moles of O2 are produced;
= 9.3992 moles of Oxygen
V = nRT / P
= (9.3992 mol) x (8.3144621 L kPa/K mol) x (21 + 273) K / (101.5 kPa)
= 226 L of oxygen
