1) same amount of carbon atoms.

That is why it is still called butane and butene.
but- always signifies 4 carbons

Answer: Option (1) is the correct answer.

Explanation:

A hydrocarbon that contains only single bonds is known as alkane. Their general formula is $C_{n}H_{2n+2}$ , where n is the number of carbon atoms.

For example, butane ( $CH_{3}CH_{2}CH_{2}CH_{3}$ ) is an alkane.

Whereas a hydrocarbon that contains at least one double bond is known as an alkene. Their general formula is $C_{n}H_{2n}$ .

For example, 2-butene ( $CH_{3}CH=CHCH_{3}$ ) is an alkene.

Hence, there are same number of carbon atoms in both butane and 2-butene.

If cells did not work together what would happen to the organisms

arlik [135]

Surely, If cells did not work together in an organism, there won't be formation of new cells and life process would stop

<h3>Living organisms </h3>

Living organisms; be it plants or animals are any organic or living system composed of cells and function as an individual entity.

All living organisms share a number of key characteristics or functions such as movement, respiration, homeostasis, reproduction, growth, evolution, competition and others.

Animals and plants also posess systems such as the digestive, skeletal, transport, nervous, excretory, respiratory and reproductive system.

Living organisms are also taxonomically classified as either unicellular microorganisms or multicellular plants and animals

So therefore, surely, If cells did not work together in an organism, there won't be formation of new cells and life process would stop

A lead mass is heated and placed in a foam cup calorimeter containing 40.0 mL of water at 17.0°C. The water reaches a temperatur

lbvjy [14]

Answer: 502 Joules

Explanation:

To calculate the mass of water, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

Density of water = 1 g/mL

Volume of water = 40.0 mL

Putting values in above equation, we get:

$1g/mL=\frac{\text{Mass of water}}{40.0mL}\\\\\text{Mass of water}=(1g/mL\times 40.0mL)=40.0g$

When metal is dipped in water, the amount of heat released by lead will be equal to the amount of heat absorbed by water.

$Heat_{\text{absorbed}}=Heat_{\text{released}}$

The equation used to calculate heat released or absorbed follows:

$q=m\times c\times \Delta T$

q = heat absorbed by water

$m$ = mass of water = 40.0 g

$T_{final}$ = final temperature of water = 20.0°C

$T_{initial$ = initial temperature of water = 17.0°C

$c$ = specific heat of water= 4.186 J/g°C

Putting values in equation 1, we get:

$q=40.0\times 4.186\times (20.0-17.0)]$

$q=502J$

Hence, the joules of heat were re-leased by the lead is 502

Each of the following are functions/characteristics of chloride except:

MakcuM [25]

<span>The ionic form of Chlorine is Chloride. Chloride helps maintain the body's fluid balance. It is a component of hydrochloric acid (HCl acid) in your stomach which helps good digestion. It is also an aide to maintain the acid-base balance of your body. Among the choices given, letter C is not a function of chloride. Excess or too much dietary intake of chloride causes hypertension.</span>
