Which of the following is the correct Lewis Dot Structure for MgBr2?
PHOTO ABOVE

Answers

Answer:

Option A

Explanation:

To know the correct answer to the question, let us write an equation illustrating the formation of MgBr₂.

This is illustrated below:

1. Magnesium (Mg) is divalent element hence it will lose 2 electrons to form magnesium ion (Mg²⁺) as shown below

Mg —> Mg²⁺ + 2e¯

2. Bromine (Br) is a univalent element. Two bromine atom will receive the two electrons (i.e each atom receives 1 electron) to form the bromide ion (Br¯) as shown below:

2Br + 2e¯ —> 2Br¯

Combine both equation

Mg + 2Br + 2e¯—> Mg²⁺ + 2e¯ + 2Br¯

Cancel out 2e¯

Mg + 2Br —> Mg²⁺ + 2Br¯

Thus we have

Br—Mg—Br

From the illustration made above, we can see that two bromine atom is receiving 1 electron each from the magnesium atom

A sample of iron has a volume of 12 mL. If the mass of this object is 94 g, what is the density of iron? Will it sink or float in water? *

Answers

Answer:

density = 7.83g/mL

It will sink in water.

Explanation:

D = mass/volume

94/12 = 7.83 g/mL

density of water is 1g/mL

Object is more dense than water, meaning it will sink.

How many centimeters are in 1 inch?

Answers

There are 2.54 cm in an inch.

The metric system is used to measure the objects based on various parameters. A centimeter is a unit of length. One inch is equivalent to 2.54 cms.

What is the metric system?

The Metric system is the system used to estimate the weight (mass), length, and capacity of the object and was first introduced in France by  Gabriel Mouton, a mathematician, and an astronomer. The metric system measures length, mass, volume, time, etc.

The metric system of length use the SI unit of meter, other units used to measure the length are centimeter, kilometer, millimeter, inches, yard, mile, feet, etc.

Given,

Length = 1 inch

It is known that an inch is equivalent to 2.54 centimeters, hence, 1 cm = 2.54 cms.

Therefore, there are 2.54 centimeters in one inch of the object.

Why would heating up the human body be a bad choice for causing a chemical reaction?

Answers

Answer:

Explained below

Explanation:

The human body has a normal core temperature of around 37°C to 38°C.

Now, if it is heated up to say 39° to 40°C, fatigue will start to set in and the brain begins to tell the muscles to slow down.

If it's now heated to higher temperatures above above 41°C, the body will begin to experience heat exhaustion and therefore will start to shut down.

Due to this process, the body can't even sweat at that stage because blood flow to the skin will stops thereby making the body feel cold and clammy. Thus, chemical processes/reaction in the body will begin to be affected and the cells inside the body will start to deteriorate and thus there is now a huge risk of having multiple organ failure.
