Choose the coefficient for blank 1 (in front of Rb) ___ Rb + ___ P --> ___ Rb3P

options:

3

1

4

2

3

Explanation:

Step 1: RxN

Rb + P → Rb₃P

Step 2: Balance RxN

We will need 3 Rb's on both sides.

3Rb + P → Rb₃P

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
