One example of matter could be <em>Light.</em>
Answer is: 127 grams <span>rams of metallic copper can be obtained.
</span>Balanced chemical reaction: 2Al + 3CuSO₄ → Al₂(SO₄)₃ + 3Cu.
m(Al) = 54.0 g.
n(Al) = m(Al) ÷ M(Al).
n(Al) = 54 g ÷ 27 g/mol.
n(Al) = 2 mol.
m(CuSO₄) = 319 g.
n(CuSO₄) = 319 g ÷ 159.6 g/mol.
n(CuSO₄) = 2 mol; limiting reactant.
From chemical reaction: n(CuSO₄) : n(Cu) = 3 : 3 (1 : 1).
n(Cu) = 2 mol.
n(Cu) = 2 mol · 63.55 g/mol.
n(Cu) = 127.1 g.
Answer:
Solid
Explanation:
Atoms are closely packed in a "<em>Solid</em>" substance, So, the substance is a solid.
Answer:
158g
Explanation:
To calculate the "weight" (mass) of ethyl alcohol, we have to use this formula:
- Density will have units of gmL when dealing with a liquid or units of gcm3 when dealing with a solid.
The mass has units of grams, g.
The volume will have units of mL or cm3
We are given the density and volume, both of which have good units so all we have to do is rearrange the equation to solve for the mass:
density×volume=massvolume×volume
Density×Volume = Mass
0.789gmL×200.0mL
Thus, ethyl alcohol weighs 158g.
c3h6 + cl2---- c3h6cl2 is a type of equation represents an addition reaction because new products are formed.
<h3>What is addition reaction?</h3>
Addition reaction is a type of reaction in which one molecule combines with another to form a bigger molecule having no other products. We can see that the above reaction has no byproduct.
So we can conclude that c3h6 + cl2---- c3h6cl2 is a type of equation represents an addition reaction because new products are formed.
