Answer:
34.7mL
Explanation:
First we have to convert our grams of Zinc to moles of zinc so we can relate that number to our chemical equation.
So: 6.25g Zn x (1 mol / 65.39 g) = 0.0956 mol Zn
All that was done above was multiplying the grams of zinc by the reciprocal of zincs molar mass so our units would cancel and leave us with moles of zinc.
So now we need to go to HCl!
To do that we multiply by the molar coefficients in the chemical equation:
This leaves us with 2(0.0956) = 0.1912 mol HCl
Now we use the relationship M= moles / volume , to calculate our volume
Rearranging we get that V = moles / M
Now we plug in: V = 0.1912 mol HCl / 5.50 M HCl
V= 0.0347 L
To change this to milliliters we multiply by 1000 so:
34.7 mL

Please refer to this. Here is the oxidation number of nitrogen in aluminum nitride, aln. <span>Since AlN has 0 charge and Al has +3 charge; charge for N = 0 - (+3) = -3. Hope this is the answer that you are looking for. Have a great day ahead!</span>
According to Boyle's Law,
" the volume of a fixed mass of gas is inversely proportional to the pressure applied on it'.
Mathmatically,
V ∞ 1 / P
Or,
V = k / P
Explanation:
The balloon filled with Neon gas outside the chamber will have greater volume than in the chamber because the pressure in the chamber is high as compared to outside. So, the outside force brings the molecule of gas to get closer to each other.
The choices can be found elsewhere and as follows:
<span>a.
Waxy needles
b.
Cone-shaped
c.
Thin trunks
d.
Low-growing
I think the correct answer is option D. The moss </span><span>campion adapted to enable its survival in the alpine biome by its ability of low-growing. Hope this answers the question.</span>
