Hi there! To calculate rate of change, you need to do y^2 - y^1 over x^2 - x^1. The y’s refer to the second number in each coordinate and the x’s refer to the first number in each coordinate. The exponents show which x and y to put in. The first pair of coordinates would be the 1’s, and the second pair of coordinates would be the 2’s. Fill in the y’s and x’s. Then subtract them from one another. The answer you get, which will be a fraction, is the rate of change ;)

yanalaym [24]

Answer:

Option B. 10

Explanation:

If 1 mol of butanol contains 6×10²⁴ atoms of H, let's calculate the amount of H.

(number of atoms  / NA)

6.02 x 10²³ atoms ___ 1 mol

6×10²⁴ atoms will occupy (6×10²⁴ / NA) = 9.96 moles

H, has 10 moles in the butano formula.

lutik1710 [3]

When transferring flammable liquids from storage drums to smaller electrically conductive containers, bonding and grounding are required. In any workplace, you should do the same whenever you move these liquids between conductive containers.

<h3>What exactly occurs in this case?</h3>

Ground dispensing drums in the area for storing and dispensing flammable liquids. Connecting the container to an already grounded, electrically conductive object grounds it. This could be a grounded metal construction framework, a buried metal plate, a metallic subsurface gas piping system, or metal water pipes. Sparks are prevented from discharging by bonding the two containers together and grounding one of them. All connections for bonding and grounding must be made from bare metal to bare metal.
