The answer is an igneous rock.
Hope this helps!!
Is this a test or something else?
The balanced chemical reaction is:
<span>CuCl2 + 2Na → 2NaCl + Cu
We are given the amount of sodium to be used up in the reaction. This will be the starting point for our calculations.
15 g Na ( 1 mol / 22.99 ) ( 1 mol Cul2 / 2 mol Na ) (134.45 g / 1 mol ) = 43.86 g CuCl2 needed to be able to obtain the maximum amount of copper.</span>
Answer:
In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.
Explanation:
That is what I think on the subject
Explanation:
Matter can be categorized into substances and mixtures.
Matter is anything that has mass and occupies spaces.
Substances are distinct matter with the following properties:
- All parts are the same throughout i.e homogeneous
- Their composition is definite
- They cannot be easily separated or broken down into simpler substances by physical means
- Separation by physical means is not easy
- They have a unique set of physical properties.
Mixtures have the following properties:
- Their composition is indefinite i.e they consist of two or more elements and/or compounds in any proportion by mass
- Their constituents retains their identity
- They can easily be separated by physical means
- They have a broad range of physical properties.
