Answer:
No because a straw is plastic look at it by this was, the energy used to create one metal straw is roughly equivalent to creating 90 plastic straws, and also produces carbon emissions equivalent to 150 plastic straws. This may not seem like a lot, but in order to offset the environmental impact of creating a metal straw, it must be used over 150 times
Explanation:
Amorphous and crystalline are the two types of matter classified by the arrangement of its atoms.
Explanation:
There are several criteria present to classify the matters present in this universe. We can classify the matter based on their physical state like solid, liquid and gas. We can also classify the matter based on their composition like pure substance and mixtures. Similarly another way of classifying the matter is based on their arrangement of atoms. If the atoms are arranged in an orderly manner, then they are termed as crystalline matter. And if the atoms are arranged in a random way, then they are termed as amorphous matter.
Thus, the two types of matter classified by the arrangement of its atoms are amorphous and crystalline.
Answer:
34,6g of (NH₄)₂SO₄
Explanation:
The boiling-point elevation describes the phenomenon in which the boiling point of a liquid increases with the addition of a compound. The formula is:
ΔT = kb×m
Where ΔT is Tsolution - T solvent; kb is ebullioscopic constant and m is molality of ions in solution.
For the problem:
ΔT = 109,7°C-108,3°C = 1,4°C
kb = 1.07 °C kg/mol
Solving:
m = 1,31 mol/kg
As mass of X = 600g = 0,600kg:
1,31mol/kg×0,600kg = 0,785 moles of ions. As (NH₄)₂SO₄ has three ions:
0,785 moles of ions×
= 0,262 moles of (NH₄)₂SO₄
As molar mass of (NH₄)₂SO₄ is 132,14g/mol:
0,262 moles of (NH₄)₂SO₄×
= <em>34,6g of (NH₄)₂SO₄</em>
