An electrical shock happens when electric $\boxed{\text{current}}$ enters the body at one point and leaves through another.

Further Explanation:

The rate of flow of electric charges is known as electric current. It is generally represented by I. It passes through the substances that carry current carriers in them. The electrons are said to be the current carriers. Electrons are the negatively charged subatomic particles which along with the atomic nucleus comprise the atom. The SI unit of electric current is Ampere or Coulomb per second. One Ampere is defined as the rate of flow of one-coulomb charge in unit time. The instrument used to measure electric current is called ammeter.

The formula to calculate the electric current is as follows:

${\text{I}} = \dfrac{{\text{Q}}}{{\text{t}}}$

Here,

I is the electric current.

Q is the amount of charge in Coulomb.

t is the time in seconds.

Conductors are the substances that permit electric current to flow through them. Metals are good conductors of heat and electricity as these have free charge carriers that move randomly and produce current. Insulators are the substances that cannot pass an electric current through them. Non-metals are bad conductors or insulators.

When an electric current passes through the human body, an electric shock is felt. It can results in skin burns, numbness, breathing problems, headache and muscle spasms. The severity of electric shock depends on the amount of electric current, time to which the body is subjected to current and the path of current through the body.

Answer: The correct answer is "current".

Explanation:

The electric shock happens when the circuit is complete with respect to ground. In this case, the electric current enters from one point through the conductor and exits from the another point.

In case of bird sitting on the electrical wire of the electric pole, it does not get electric shock as the circuit is not complete with respect to the ground. That is why the electric current does not flow through its body.

Therefore, an electrical shock happens when electric current enters the body at one point and leaves through another.

Groups of atoms that are added to carbon backbones and give them unique properties are known as

Irina-Kira [14]

Answer:

Groups of atoms that are added to carbon backbones and give them unique properties are known as Functional Groups.

Explanation:

In organic chemistry they are called as Functional Group because they are the active part of a molecule. These groups give a unique characteristic to molecule both chemically and physically. Also, each functional group represent a different class of compounds.

Examples:

S No. Functional Group Name

1 R--X Alkyl Halides

2 R--OH Alcohols

3 R--NH₂ Amines

4 R--O--R Ethers

5 R--CO--R Ketones

6 R--CO--H Aldehydes

7 R--CO--OH Carboxylic acids

8 R--CO--X Acid Halides

10 R--CO--NR₂ Acid Amides

11 R--CO-OR' Esters

A compound that is composed of carbon, hydrogen, and oxygen contains 70.6% C, 5.9% H, and 23.5% O by mass. The molecular weight

zhannawk [14.2K]

Answer: The molecular formula will be $C_8H_8O_2$

Explanation:

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of C= 70.6 g

Mass of H = 5.9 g

Mass of O = 23.5 g

Step 1 : convert given masses into moles.

Moles of C = $\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{70.6g}{12g/mole}=5.9moles$

Moles of H = $\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{5.9g}{1g/mole}=5.9moles$

Moles of O = $\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{23.5g}{16g/mole}=1.5moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = $\frac{5.9}{1.5}=4$

For H = $\frac{5.9}{1.5}=4$

For O = $\frac{1.5}{1.5}=1$

The ratio of C : H: O= 4: 4:1

Hence the empirical formula is $C_4H_4O$

The empirical weight of $C_4H_4O$ = 4(12)+4(1)+1(16)= 68g.

The molecular weight = 136 g/mole

Now we have to calculate the molecular formula.

$n=\frac{\text{Molecular weight }}{\text{Equivalent weight}}=\frac{136}{68}=2$

The molecular formula will be= $2\times C_4H_4O=C_8H_8O_2$

A scientist measures the mass of two liquids before and after combining them. The mass after combining the liquids is less then

Lelu [443]

Answer:

A chemical change occurred and a gas was produced.

Step-by-step explanation:

If there is no chemical reaction, the Law of Conservation of Mass says that

Total mass = Mass 1 + Mass 2

However, if the two liquids react and give off a gas, then

Total mass = Mass 1 + Mass 2 + Mass of gas

You are not measuring the mass of the gas, so the mass of the liquids after mixing is less than it was before mixing.

For example, if Liquid 1 was a solution of HCl and Liquid 2 was a solution of Na₂CO₃, they would give off CO₂ on mixing. but you would not be measuring the mass of the CO₂.
