Suggest a likely pH for a reasonable concentrated solution of hydrogen atatide in water ​

Chemistry
1 answer:
Gelneren [198K]3 years ago
6 0

Answer:

It can be said that a reasonable concentration of HAt in water would be 0

Explanation:Hydrogen astatide is a chemical compound with the chemical formula HAt, consisting of an astatine atom covalently bonded to a hydrogen atom.

This chemical compound can dissolve in water to form hydroastatic acid, which exhibits properties very similar to the other four binary acids, and is in fact the strongest among them. So we can safely say that a reasonable concentration of HAt in water would be 0. However, it is limited in use due to its ready decomposition into elemental hydrogen and astatine.

A car with a mass of 3,500lbs accelerates negatively from 35m/s to 8m/s in 8s. What is the
Salsk061 [2.6K]

Answer:

a=-3.37\ m/s^2

Explanation:

Given that,

A car accelerates negatively from 35m/s to 8m/s in 8s.

We need to find the car's acceleration.

Initial speed, u = 35 m/s

Final speed, v = 8 m/s

Time, t = 8 s

The acceleration of an object is equal to the rate of change of velocity. So,

a=\dfrac{v-u}{t}

Put all the values,

a=\dfrac{8-35}{8}\\\\a=-3.37\ m/s^2

So, the acceleration of the car is equal to -3.37\ m/s^2.
