Answer:

ANSWER

ANSWER: +1

EXPLANATION

What is the change in oxidation number of bromine in the following re-dox reaction Cl 2 +2HBr 2HCl+Br 2 A -2;0 B) -1;0 C) 0: -1 D) 0;-2

for Cl 2 +2HBr 2HCl+Br 2 , the Cl in Cl2 is reduced from "0" to

"-1" and the Br in HBr is oxidized from "-1" to "0"

So the change in oxidation number is +1

What is the velocity of a 485 kg elevator that has 5900 J of energy?
Ganezh [65]

The velocity of a 485 kg elevator that has 5900 J of energy is 108.6 m/s

<h3>What is the velocity of the elevator?</h3>

A moving elevator possesses kinetic energy due to its motion.

The velocity of the elevator is calculated from the formula of kinetic energy.

The kinetic energy formula is : Kinetic energy = ¹/₂mv₂

The velocity, v = √2KE/m

v = √(2 * 5900/485)

v = 108.6 m/s

In conclusion, the velocity of the elevator is calculated from the kinetic energy and mass of the elevator.

What can you tell me about the charge signs on the spheres
bazaltina [42]
<span>A similar thing occurred with the circles as did with the electroscope. When we initially brought the charged pole close to, the bar pulled in the circle since it was of polarization. At that point, once the bar touched the circle, the pole repulsed the circle. This is on the grounds that once the pole and circle touched, the electrons exchanged thus did the protons, consequently leaving the circle with a positive net charge. The nearer the bar is to the circle the more it repulsed, however, it didn't influence the charge of the circle once the circle was touched by the pole.</span>

Both natural products and synthetic products come from natural resources. Explain why this statement is true.
xz_007 [3.2K]

Explanation:

All resources used in making all products can be traced to their natural origin. What differentiates a natural product from a synthetic one is the level of processing that goes into making synthetic products.

  • For example, a synthetic product such as plastic is actually derived from natural product.
  • Instead of using the sap of rubber plants for making this product, scientists engineered a way to produce plastics from petroleum products which are derived from crude oil.
  • Most synthetic products are merely products of alternate source of manufacturing which are well engineered.

What is in lactic acid that it can lower pH levels?.
-BARSIC- [3]

Answer:

On the basis of this explanation, if the rate of lactate production is high enough, the cellular proton buffering capacity can be exceeded, resulting in a decrease in cellular pH. These biochemical events have been termed lactic acidosis. ... Every time ATP is broken down to ADP and Pi, a proton is released
