Answer:
The formula mass of MgCl2 is 95, 3 grams (the weight of 1 mol of compound)
Explanation:
We calculate the weight of 1 mol of MgCl2:
Weight of 1mol of MgCl2=atomic weight Mg + (atomic weight Cl)x 2=
24, 3 grams + 2 x 35, 5 grams = 95, 3 grams/mol MgCl2
Answer: Two water molecules interact to form a hydronium ion and a hydroxide ion.
Explanation:
Answer:
D. The cation will use a type II naming system
Explanation:
As the element becomes stable, Option D is NOT taking place. That means that as the element becomes stable, the cation will NOT use a type II naming system. This is because in Type II binary compounds, the metal is not found in either Group 1 or Group 2 on the periodic table. It is as a result of this that the cation will not use a type II naming system.
Group 1 and Group 2 elements make use of type I naming system because in Type I binary compounds, the metal is present.
Option D is the correct answer.
To cause death within hours of exposure to radiation, the dose needs to be very high, 10Gy or higher, while 4-5Gy will kill within 60 days, and less than 1.5-2Gy will not be lethal in the short term. However all doses, no matter how small, carry a finite risk of cancer and other diseases. Patients exposed to radiation between 8 to 30 Gy experience nausea and severe diarrhea within an hour, and they die between 2 days and 2 weeks after exposure. Absorbed doses greater than 30 Gy cause neurological damage
Answer:
30 feet /second
Explanation:
60 feet/ 2 sec = 30 feet/sec
