1) Chemical equation.
2) Types of reaction.
In the reaction above, we can see that two different compounds get together to form a new compound. <em>This is called a synthesis or a combination.</em>
Decomposition: A compound is broken down into simpler compounds.
Combustion: A compound containing Carbon and Hydrogen combines with oxygen.
Double replacement: Positive and negative ions in two compounds switch places.
Answer:
10 nitrogens
Explanation:
The 2 is the number of nitrogens in a molecule of N2. There are 2 of them.
The 5 is a whole different critter. It tells you that it was part of an equation and it took 5 molecules of Nitrogen to balance the equation. You only see numbers to the right of a molecule when the molecule is in an equation.
5 (2)=10
They are both related to hold the shape or a part of an organism.
<h2>
Answer:It always contains certain elements,It always contains elements in definite proportions.,It cannot contain atoms from more than one element.</h2>
Explanation:
The mineral need not occur always in a pure form.On purification we get the exact chemical composition.
The mineral always has a definite chemical composition which means the number of elements and types of elements in the mineral does not change.
Since the mineral has definite composition,the elements in the mineral has definite proportions.
The mineral can be a compound.So,there can be atoms from more than one element.
Hello Mlbozer,
Hope your having a great day! Gasses are known for having molecules that 'run' in a way. They all are Spread Out, and bounce off each other. Its a big mess, and is more 'spread out' than even liquid, in fact its the most open form of the three! So your answer is false!
Thank you,
