1. Is a hurricane or a tornado deadlier on average?

Vilka [71]

Stoms or tornadoes cause about ten times more damage a year, on average, as hurricanes. Storms often cause more complete destruction than hurricanes because of their large size, long-term duration, and their varied potential for damage to property.

Storms can be very severe storms, hurricanes often last a long time, cover most of the earth and cause great damage. The wind from the strongest calves is stronger than the one from the strongest storms.

A 53. 5 mL ample of an 5. 4 % (m / v) KBr olution i diluted with water o that the final volume i 205. 0 mL Expre your anwer to t

gogolik [260]

The concentration after dilution is 1.4%.

We are aware that concentration and volume are related to each other by the formula -

$C_{1}$ $V_{1}$ = $C_{2}$ $V_{2}$ , where we have initial concentration and volume on Left Hand Side and final concentration and volume on Right Hand Side.
