In the question "Continued deforestation will most likely lead to _______." the correct answer is "an increase in the number of endangered species" (option b).
Deforestation is the clearing of forest areas for use for non forest activities. Because there are a lot of animals that use forests as their home, clearing of the forest will make them homeless and will subject them to conditions that may lead to their death and possible extinction.

Divide 50 miles an hour or mph by 0.621, should give you 80.51 kilometers an hour or km/hr, this being the speed limit on that street in km/hr. If you're going 120 km/hr on an 80.51 kilometers an hour road you are speeding, as you're above the speed limit.

Problem PageQuestion A major component of gasoline is octane . When octane is burned in air, it chemically reacts with oxygen ga

Ivahew [28]

Answer:

grams of oxygen = 21.40 g

Explanation:

octane → C8H18

The chemical reaction needs to be represented with a chemical equation before solving. The equation also need to be balanced.

C8H18 + O2 → CO2 + H2O

Balanced equation

2C8H18 + 25O2 → 16CO2 + 18H2O

Molar mass of octane = 12 × 8 + 18 = 96 + 18 = 114 g

Mass of octane in the chemical equation = 2 (114) = 228 g

molar mass of oxygen = 32 g

mass of oxygen in the chemical equation = 25 × 32 = 800 g

if 228 g of octane react with 800 g of oxygen

6.1 g of octane will require ? grams of oxygen

cross multiply

grams of oxygen = 6.1 × 800/228

grams of oxygen = 4880 /228

grams of oxygen = 21.4035087719

grams of oxygen = 21.40 g

When 0.040 mol of propionic acid, c2h5co2h, is dissolved in 750 ml of water, the equilibrium concentration of h3o+ ions is measu

WITCHER [35]

Answer is: Ka for propanoic acid is 6,57·10⁻⁵.
Chemical reaction: C₂H₅COOH(aq) + H₂O(l) ⇄ C₂H₅COO⁻(aq) + H₃O⁺(aq).
n(C₂H₅COOH) = 0,04 mol.
V(C₂H₅COOH) = 750 mL = 0,75 L.
c(C₂H₅COOH) = 0,04 mol ÷ 0,75 L.
c(C₂H₅COOH) = 0,053 mol/L = 0,053 M.
[C₂H₅COO⁻] = [H₃O⁺] = 1,84·10⁻³ M = 0,00184 M.<span>
[HCN] = 0,053 M - 0,00184 M = 0,0515 M.
Ka = [</span>C₂H₅COO⁻] · [H₃O⁺] / [C₂H₅COOH].
Ka = (0,00184 M)² / 0,0515 M.
Ka = 6,57·10⁻⁵.
