Answer:
yes
Explanation:
it wont dissolve because when water is cold its molecules dont separate
The molecule of mixture cannot be seen hence, it will be considered as homogeneous mixture.
<h3>
What is molecule?</h3>
A molecule is just a collection of more than two atoms bound together by chemical bonds; depending on the context, the phrase doesn't have to include ions that meet this requirement.
<h3>
What is homogeneous mixture?</h3>
Solids, liquids, as well as gases, can all be homogeneous mixtures. Through, they have almost the same look and chemical makeup.
When sugar will be dissolved, the sucrose molecules get separated from one another. The materials that make up individual molecules stay together like sucrose molecules sucrose molecules, so the molecule will not break up.
Therefore mixture can be considered as molecule and homogeneous mixture.

Above question is incomplete. Complete question is
<span>What is the missing number in the nuclear reaction 175 78 pt -- 4 2 He plus 76 Os?
....................................................................................................................
Solution:
Reaction involved in present nuclear event is
</span>175 78 Pt → 4 2 He + 76 Os
In above nuclear reaction, atomic mass number of Os is missing. The atomic mass number of Os = 175 - 4 = 171
Thus, complete nuclear can be written as
175 78 Pt → 4 2 He + 171 76 Os
Answer:
The equation shows balance.
Explanation:
You can easily count the number of elements on each side.
On the left side of the equation, you have 2 moles of Na and 2 moles of Cl.
On the right side of the equation, you also have 2 moles of Na and 2 moles of Cl because the two elements formed a compound meaning that whatever number is in front of them, both elements will receive the same number.
