Answer:
In very hot, humid weather you might feel the air is heavier because moving around seems to take more energy than on dry days. Sticky days probably feel “heavier” because heat and high humidity slows the evaporation of perspiration, your body grows hotter and this saps your strength

Answer:
![m=7.07gH_{2}SO_{4}](https://tex.z-dn.net/?f=m%3D7.07gH_%7B2%7DSO_%7B4%7D)
Explanation:
1. Take in account the sulfuric acid at STP:
![1840\frac{g}{L}](https://tex.z-dn.net/?f=1840%5Cfrac%7Bg%7D%7BL%7D)
2. Density is expressed as the ratio between the mass and the volume of a substance so:
![d=\frac{m}{V}](https://tex.z-dn.net/?f=d%3D%5Cfrac%7Bm%7D%7BV%7D)
Solving for m:
![m=\frac{V}{d}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7BV%7D%7Bd%7D)
3. Replace values:
![m=\frac{1.30*10^{4}L}{1840\frac{g}{L}}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1.30%2A10%5E%7B4%7DL%7D%7B1840%5Cfrac%7Bg%7D%7BL%7D%7D)
![m=7.07gH_{2}SO_{4}](https://tex.z-dn.net/?f=m%3D7.07gH_%7B2%7DSO_%7B4%7D)

Answer:
All secondary consumers will die because they will lose their food source
Molarity after dilution : 0.0058 M
<h3>Further explanation
</h3>
The number of moles before and after dilution is the same
The dilution formula
M₁V₁=M₂V₂
M₁ = Molarity of the solution before dilution
V₁ = volume of the solution before dilution
M₂ = Molarity of the solution after dilution
V₂ = Molarity volume of the solution after dilution
M₁=0.1 M
V₁=6.11
V₂=105.12
![\tt M_2=\dfrac{M_1.V_1}{V_2}=\dfrac{0.1\times 6.11}{105.12}=0.0058~M](https://tex.z-dn.net/?f=%5Ctt%20M_2%3D%5Cdfrac%7BM_1.V_1%7D%7BV_2%7D%3D%5Cdfrac%7B0.1%5Ctimes%206.11%7D%7B105.12%7D%3D0.0058~M)
