Which displacement reaction is most likely to occur? use the resources to you. a. bacl2 + ca → cacl2 + ba b. bacl2 + sr → srcl2 + ba c. bacl2 + 2na → 2nacl + ba d. bacl2 + mg → mgcl2 + ba

The correct answer is C

43.452

step-by-step explanation:

284 times .153 = 43.452

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.
