Which two types of cells are involved in fertilization?
✅
- Gametes are an organism's reproductive cells. The female gametes are called ova or egg cells, and the male gametes are called sperm.
- During fertilisation, the gametes (an egg and sperm) fuse to form a zygote.

Aluminum to hydrogen gas ratio is 2 : 3 by looking at the coefficients of aluminum on the reactant side and hydrogen gas on the product side.
So from 2.0 mol of Al, 3.0 mol of H2 would form.
That would be oxidation.
Oxidation is loss of electrons
Reduction is gain of electrons
To determine the amplitude of a transverse wave, measure the highest amount of disturbance from the equilibrium that the wave experiences.
Answer:
1. NaN₃(s) → Na(s) + 1.5 N₂(g)
2. 79.3g
Explanation:
<em>1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid sodium azide (NaN₃) into solid sodium and gaseous dinitrogen.</em>
NaN₃(s) → Na(s) + 1.5 N₂(g)
<em>2. Suppose 43.0L of dinitrogen gas are produced by this reaction, at a temperature of 13.0°C and pressure of exactly 1atm. Calculate the mass of sodium azide that must have reacted. Round your answer to 3 significant digits.</em>
First, we have to calculate the moles of N₂ from the ideal gas equation.
![P.V=n.R.T\\n=\frac{P.V}{R.T} =\frac{1atm.(43.0L)}{(0.08206atm.L/mol.K).286.2K} =1.83mol](https://tex.z-dn.net/?f=P.V%3Dn.R.T%5C%5Cn%3D%5Cfrac%7BP.V%7D%7BR.T%7D%20%3D%5Cfrac%7B1atm.%2843.0L%29%7D%7B%280.08206atm.L%2Fmol.K%29.286.2K%7D%20%3D1.83mol)
The moles of NaN₃ are:
![1.83molN_{2}.\frac{1molNaN_{3}}{1.5molN_{2}} =1.22molNaN_{3}](https://tex.z-dn.net/?f=1.83molN_%7B2%7D.%5Cfrac%7B1molNaN_%7B3%7D%7D%7B1.5molN_%7B2%7D%7D%20%3D1.22molNaN_%7B3%7D)
The molar mass of NaN₃ is 65.01 g/mol. The mass of NaN₃ is:
![1.22mol.\frac{65.01g}{mol} =79.3g](https://tex.z-dn.net/?f=1.22mol.%5Cfrac%7B65.01g%7D%7Bmol%7D%20%3D79.3g)
