Answer:

used to keep track of very small and very large numbers during mathematical calculations

Explanation:

Scientific notation makes data easy to understand and manageable. It is used to express decimal numbers that are cumbersome to write. They simplify mathematical operations.  

For example a number such as 1877655600 can be conveniently expressed in scientific notation as 1.87 x 109. Similarly a number such as 0.000000789 can be conveniently expressed in scientific notation as 7.89 x 10-7.

A sealed 1.0 l flask is charged with 0.500 mol of i2 and 0.500 mol of br2. an equilibrium reaction ensues: i2 (g) br2 (g) 2ibr (
user100 [1]

The value of Keq = 110

Let's know how to get it :


According to the equilibrium reaction equation :


I2(g) + Br2(g) → 2IBr(g)


now we need to get the value of Keq


when the Keq expression is:


Keq = [IBr]^2/ [I] [Br]


when we have [IBr] at equilibrium = 0.84 so we need to get [I] &[Br] at equilibrium .


when [Br2] = [I2] = 0.5 - 0.84 / 2


= 0.08 M


so, by substitution


∴ Keq = (0.84)^2/(0.08)^2


= 110

Answer:

C. Water passes into the salt solution, dehydrating bacterial cells and making them harmless.

Explanation:

The salt solution is hypertonic to the bacterial cells and as such, water molecules will move from the bacterial cells into the salt solution, dehydrating the cells and rendering them harmless.

Option A is also true but it is irrelevant to the question asked. Option B and D are wrong.

The correct option is C.
