Lipids with high polyunsaturatd fatty acid content are ____________ at room temperature.
kow [346]
The answer to this question would be liquid.

<span>Lipids with high polyunsaturated fatty acid mostly found as a liquid, but the saturated one would be solid at room temperature. A molecule with higher molecular weight will have the higher boiling point and it more likely to be solid at room temperature.
Unsaturated fat is more healthy than saturated fat and it is recommended to reduce saturated fat consumption as it was linked to many diseases.

How does biodiversity generate the economy?
Lesechka [4]
Biodiversity helps an economy grow and develop over time because such as the circle of life we need other things in order to evolve such as trees so we can be able to breathe and plants so the herbivores can eat so we can eat them because we are all part of a cycle and in order to keep the cycle going we need biodiversity to keep the food chain going and our economy well and lifted

Which answer correctly ranks the atoms in terms of decreasing electronegativity (the highest electronegativity first)? which ans
Degger [83]

Answer:

O, N, C, H

Explanation:

Electronegativity of an element is the property that combines the ability of its atom to lose or gain electrons. It measures the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.

On the periodic table, Electronegativity increases across the period but decreases down a group.

To solve the given problem, let us use thE Pauling's table of electronegativities to compare the electronegativities of the elements.

On the table:

C = 2.5

H = 2.1

O = 3.5

N = 3.0

In terms of decreasing electronegativities, the atoms are arranged as:

O N C H

150.0 grams of an isotope with a half-life of 36.0 hours is present at time zero. How long will it take
leonid [27]

Given :

Initial mass , a = 150 gm .

Half time ,

t_{\dfrac{1}{2}}=36 \ hours.

Final mass , x = 18.75 gm .

To Find :

The time taken to decay 18.75 gm .

Solution :

We know , time taken is given by :

t=\dfrac{1}{k}\times ln(\dfrac{a}{a-x})

Here , k is a constant given by :

k=\dfrac{0.693}{t_{\dfrac{1}{2}}}\\\\\\k=\dfrac{0.693}{36}

Putting all given value in above equation :

We get :

t=\dfrac{36}{0.693}\times ln(\dfrac{150}{150-18.75})\\\\t=6.94\ hours

Therefore , time taken is 6.94 hours .

Hence , this is the required solution .
