Answer:

60%

Explanation:

E. coli is a bacterium found in large quantities in the digestive system of humans, cows and other mammals. In several countries, the bacterium has been responsible for a large number of outbreaks of contamination. In most cases, the disease causes nonlethal problems in the stomach. However, enterohemorrhagic E. coli (ECEH) causes more severe symptoms, ranging from bloody diarrhea to haemolytic uremic syndrome.

In any living organism genes are not active all the time, gene activation results from the response the organism needs for a given time or situation. In the case of E. coli, only 60% of its genes are active at the same time and all the time, the other 40% are waiting for the moment when some protein will need to be coded. Since bacteria have only one cell, gene activation is done very quickly to ensure survival.

Hydrogen is a special ,because it can act like two groups,____and_____

LuckyWell [14K]

Answer:

First and seventeenth group.

Explanation:

Hydrogen is a special case as it has only one electron in its outermost orbital.

The hydrogen can lose or can accept electron easily.

Thus it can form positive ion similar to alkali metals and negative ion similar to halogens.

Thus it can fall into two groups

a) I group [Alkali metals]

b) 17th Group [Halogens]

A 1.24g sample of a hydrocarbon, when completely burned in an excess of O2 yields 4.04g Co2 and 1.24g H20. Draw plausible struct

arsen [322]

Answer:

Plausible structure has been given below

Explanation:

Molar mass of $CO_{2}$ is 44 g/mol and molar mass of $H_{2}O$ is 18 g/mol
Number of mole = (mass/molar mass)

4.04 g of $CO_{2}$ = $\frac{4.04}{44}moles$ $CO_{2}$ = 0.0918 moles of $CO_{2}$

1 mol of $CO_{2}$ contains 1 mol of C atom

So, 0.0918 moles of $CO_{2}$ contains 0.0918 moles of C atom

1.24 g of $H_{2}O$ = $\frac{1.24}{18}moles$ $H_{2}O$ = 0.0689 moles of $H_{2}O$

1 mol of $H_{2}O$ contain 2 moles of H atom

So, 0.0689 moles of $H_{2}O$ contain $(2\times 0.0689)moles$ of $H_{2}O$ or 0.138 moles of $H_{2}O$

Moles of C : moles of H = 0.0918 : 0.138 = 2 : 3

Empirical formula of hydrocarbon is $C_{2}H_{3}$

So, molecular formula of one of it's analog is $C_{4}H_{6}$

Plausible structure of $C_{4}H_{6}$ has been given below.
