On the off chance that the red blood cells are smaller than ordinary, this is called microcytic anemia. The significant reasons for this sort are low-level iron, anemia, thalassemia.

Wirte the benefits and harmful effects of micro organisms in our life? ans

Vesnalui [34]

Answer:

Microorganisms have uses and benefits across all aspects of human life. From the bacteria that help humans digest food to the viruses that help plants resist heat, bacteria, viruses and fungi – when used properly – are key components in food, medicine, agriculture and other areas. In the future, they may even be core components of infrastructure and other new technologies.

Explanation:

You mean microorganisms, yes?

If the pressure on a gas at -73°C is doubled but its volume is held constant, what will its final temperature be in degrees Cels

Gre4nikov [31]

Answer:

127°C

Explanation:

This excersise can be solved, with the Charles Gay Lussac law, where the pressure of the gas is modified according to absolute T°.

We convert our value to K → -73°C + 273 = 200 K

The moles are the same, and the volume is also the same:

P₁ / T₁ = P₂ / T₂

But the pressure is doubled so: P₁ / T₁ = 2P₁ / T₂

P₁ / 200K = 2P₁ / T₂

1 /2OOK = (2P₁ / T₂) / P₁

See how's P₁ term is cancelled.

200K⁻¹ = 2/ T₂

T₂ = 2 / 200K⁻¹ → 400K

We convert the T° to C → 400 K - 273 = 127°C

He structure of the product, C, of the following sequence of reactions would be:

NikAS [45]

Answer:

Explanation:

The complete question can be seen in the image attached.

We need to understand what is actually going on here. In the first step that yields product A, the sodamide in liquid ammonia attacks the alkyne and abstracts the acidic hydrogen of the alkyne. The second step is a nucleophilic attack of the C6H5C≡C^- on the alkyl halide to yield product B (C6H5C≡C-CH3CH2).

Partial reduction of B using the Lindlar catalyst leads to syn addition of hydrogen to yield structure I as the product C.

Calculate the number of moles when 3.00l of a gas at 814 mmhg and 25 °c?

Mariulka [41]

Volume=V=3L
Pressure=P=814mmHg
Temp=T=25°C

No of moles=n

$\\ \rm\rightarrowtail PV=nRT$

$\\ \rm\rightarrowtail n=\dfrac{PV}{RT}$

$\\ \rm\rightarrowtail n=\dfrac{814(3)}{25R}$

$\\ \rm\rightarrowtail n=2442/25R$

$\\ \rm\rightarrowtail n=97.7Rmol$

water interacts with polar substances like –oh groups but not with non-polar substances like methyl (−ch3) or ethyl groups (−ch2

Brilliant_brown [7]

CH3OH and CH3CH2CH2OH will easily dissolve in water based on polarity not on size.

<h3>What is Polarity ?</h3>

In chemistry, polarity describes the type of bonds that exist between atoms. Atoms share electrons when they join forces to form chemical bonds. When one of the atoms applies a stronger attractive force to the bond's electrons, a polar molecule is created.

For instance, the chlorine atom is slightly negatively charged while the hydrogen atom in hydrogen chloride is slightly positively charged.

Water is polar due to its form even though its molecules have no net charge. The molecule's hydrogen ends are positive, and its oxygen ends are negative. Water molecules are drawn to other polar molecules and to one another as a result.
