Answer: To minimize the chance the bracelet pulling over a test tube, causing a spill.

Explanation:

A chemistry lab is a laboratory where the potential hazards related to the chemicals may result if safety precautions are neglected. The chances of the cause of chemical splash, burns from chemicals or fire hazards can possibly  happen in a chemistry lab. The use of ornaments should be avoided in the chemical lab. Proper safety measures are to be taken to protect the body from chemical hazards by wearing close toed shoes, lab coat and gloves.

A dangling bracelet worn during the heating process is likely to spill off the acid solutions by pulling over a test tube. The test tube neck may get caught in the dangling bracelet. The test tube may collapse and break. Thus the dangling bracelet should be avoided during the process of heating.

A 1.50-V battery supplies 0.414 W of power to a small flashlight. If the battery moves 4.93 1020 electrons between its terminals
slamgirl [31]

Answer:

2.86×10⁻¹⁸ seconds

Explanation:

Applying,

P = VI................ Equation 1

Where P = Power, V = Voltage, I = Current.

make I the subject of the equation

I = P/V................ Equation 2

From the question,

Given: P = 0.414 W, V = 1.50 V

Substitute into equation 2

I = 0.414/1.50

I = 0.276 A

Also,

Q = It............... Equation 3

Where Q = amount of charge, t = time

make t the subject of the equation

t = Q/I.................. Equation 4

From the question,

4.931020 electrons has a charge of (4.931020×1.6020×10⁻¹⁹) coulombs

Q = 7.899×10⁻¹⁹ C

Substitute these value into equation 4

t =  7.899×10⁻¹⁹/0.276

t = 2.86×10⁻¹⁸ seconds
