The mixture of alcohol and water is a homogeneous mixture where the components are thoroughly mixed and cannot be separated by naked eyes.
The easiest way to separate alcohol from water is by boiling the mixture. The boiling point of alcohol is lower than that of water. Therefore, alcohol will turn into steam before water. This steam can easily be condensed into a separate container.
Answer:
3.5 mol
Explanation:
Step 1: Given data
Moles of HCl: 7.0 mol
Step 2: Write the balanced equation
Fe(s) + 2 HCl(aq) ⇒ FeCl₂(aq) + H₂(g)
Step 3: Calculate the moles of H₂ gas produced from 7.0 moles of HCl
According to the balanced equation, the molar ratio of HCl to H₂ is 2:1.
7.0 mol HCl × 1 mol H₂/2 mol HCl = 3.5 mol H₂
Organisms is an environment or habitat for species
A. 4,3,2.
When you add a coefficient it multiplies what it is connected to in math. So when you have 4 Fe, that means there are 4 Fe atoms. When you add a 3 in front of O₂, that will make 6 O atoms. Since the product (right) side is Fe₂0₃, and you need to add a 2 in front of it to balance the equation. After adding the coefficients you will have 4 Fe atoms and 6 O atoms on both the reactants (left) side and the products (right side. Hope this helps!
<span>What would happen to the volume-to-temperature ratio if:
1. Lower ratio, because the volume of the system is lower than the temperature.
2. Lower, since the volume is still small as compared to temperature
4. Higher, the system has a higher value of volume.</span>
