The answer is B because none of the other options are true.
Find molar mass of MgCl2 so M=<span>95.211 g/mol
N=m/M
N=332/95.2
N=3.487

Answer:
That is extremely confusing. Try contacting your prof.
Explanation:
Answer:
103.3 g
Explanation:
Data Given:
Volume of carbon tetrachloride (v) = 65.0 mL
Density of carbon tetrachloride (d) = 1.59 g/cm³
Solution:
Convert volume of carbon tetrachloride from ml to cm³
1 ml = 1 cm³
so,
65.0 mL = 65.0 cm³
Formula used to calculated mass of carbon tetrachloride should be taken for experiment.
d = m/v
Rearrange the above equation:
m = d x v . . . . . . .(1)
Put values in equation 1
m = 1.59 g/cm³ x 65.0 cm³
m = 103.3 g
Answer:
Invasive species, runoff pollution, and climate change.
Explanation:
Invasive species, such as Burmese pythons, threaten the Florida Everglades because they are not native to the natural habitat. Pythons eat the native animals, but they don't have any predators.
Pollution from nearby farms and roads enters the water and damages the ecosystem of the Everglades and Louisiana wetlands. Toxic chemicals lead to detrimental effects for both humans and wildlife.
Humans have drained swampy areas to allow for development. However, this has led to the Everglades drying up and even burning in recent years.
