Answer:
Conserving water can help alleviate the effects of water shortages in any given community. Water use drains other resources. Using in-house water resources requires energy to deliver the water to your home. This energy-use increases when you use hot water since a lot of energy goes into heating.

Answer:
27.06 mL.
Explanation:
- Firstly, we need to calculate the molarity of acrylic acid.
Molarity is the no. of moles of solute dissolved in a 1.0 L of the solution.
M = (no. of moles of acrylic acid)/(V of the solution (L))
M = (mass/molar mass)acrylic acid / (V of the solution (L))
mass of acrylic acid = 0.0975 g, molar mass of acrylic acid = 72.06 g/mol, V of the solution = 250 mL = 0.25 L.
∴ M = (0.0975 g/72.06 g/mol)/(0.25 L) = 0.0054 M.
- For the acid-base neutralization, we have the role:
The no. of millimoles of acid is equal to that of the base at the neutralization.
<em>∴ (XMV) NaOH = (XMV) acrylic acid.</em>
X is the no. of reproducible H⁺ (for acid) or OH⁻ (for base),
M is the molarity.
V is the volume.
X = 1, M = 0.05 M, V = ??? mL.
X = 1, M = 0.0054 M, V = 250.0 mL.
∴ V of NaOH = (XMV) acrylic acid/(XM) NaOH = (1)(0.0054 M)(250.0 mL)/(1)(0.05 M) = 27.06 mL.
Answer:
the answer is the option "a"
Explanation:
in petroleum polycyclic aromatic hydrocarbons are found. These organic compounds are composed of aromatic rings. PAH (Polycyclic Aromatic Hydrocarbons), are formed during the incomplete combustion of any type of organic matter. In general, exposure will be to a mixture of PAHs.
