Answer:
1.7L of water.
Explanation:
Given parameters:
Volume of hydrogen gas = 1.7L
Unknown:
Volume of water produced = ?
Solution:
A synthesis reaction is one in which two compounds or molecules combines together to give a product or products.
Synthesis of water from hydrogen gas is represented by the equation below:
2H₂ + O₂ → 2H₂O
We clearly see that;
2 mole of hydrogen gas gives 2 mole of water as the product;
From Gay-lussac's law of combining volume "when gases react, they do so in volumes which bear a simple ratio to one another and to the volume of the product if gaseous, temperature and pressure remaining constant".
2H₂ + O₂ → 2H₂O
2 volumes of hydrogen gas will produce 2 volumes of water
1.7L of hydrogen gas will also produce ; 1.7L of water.
Answer: 30,000
Explanation: I'm taking gradpoint
Answer is: It expands when it freezes.
When molecule frezes, it lose energy. When molecules are far apart, it means the volume is greater and it expands.
For example, ice expands when water is freezing.
Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.
The typical measure for the distance between stars is the light-year. Light-year and parsec are units used to quantify the enormous distances in the universe.
The distance between stars is typically measured in light-years. This term, 'light-year', refers to the distance that light can travel in one year, which is approximately 9.461 trillion kilometers or 5.879 trillion miles. Another less commonly used unit is the parsec, which is equivalent to about 3.26 light years. Such large units are necessary due to the vast distances between stars in the universe.
So, The distance between stars is typically measured in light-years.
