The process by which plants make food is photosynthesis. Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air. Autotrophs are the class of plants that are capable of preparing their own food.

(5x/100)+(10y/100)=200
=> 5x+10y=20000
=> x+2y=4000 -(1)
x+y=2800 -(2)
=> 0+y=1200 (on substraction)
x=2800-1200=1600
Therefore, no. of boys= 1600
and no. of girls = 1200.

significance of ψ and ψ2 in chemistry

Posted by Ekam Latti 4 years, 6 months ago (11369000)

CBSE > Class 11 > Chemistry

1 answers

Sia ? 4 years, 6 months ago (6945213)

ψ is a wave function and refers to the amplitude of electron wave i.e. probability amplitude. It has got no physical significance. The wave function ψ may be positive, negative or imaginary.
[ψ]² is known as probability density and determines the probability of finding an electron at a point within the atom. This means that if:
(i) is zero, the probability of finding an electron at that point is negligible.
(ii) [ψ]² is high, the probability of finding an electron is high i.e. electron is present at that place for a long time.
(iii) [ψ]² is low. the probability of finding an electron is low i.e. electron is present at that place for a shorter time.

Convert into mole - 12g of oxygen gas

Posted by Sanket Kumar ? 4 years, 6 months ago (11368589)

CBSE > Class 09 > Science

1 answers

Sia ? 4 years, 6 months ago (6945213)

Oxygen exists in the diatomic form in a gaseous state (O₂). Therefore, for finding the molar mass of diatomic oxygen we should multiply the atomic mass (16) by two.
Molar mass of O₂ = 16×2
= 32 g/mol
By using the above-mentioned formula, we can write,
Number of moles in 12 g oxygen gas = 12g32gmol−1
= 0.375 mol
Therefore, 12 g of oxygen gas has 0.375 moles.

Posted by Abhi Gamer 4 years, 6 months ago (10686100)

CBSE > Class 10 > Social Science

1 answers

Sia ? 4 years, 6 months ago (6945213)

Soil erosion is displacement of upper layer of soil.
There are three main different types of soil erosion :-
1. Wind erosion: Wind erosion is removal of soil particle by the forces of kinetic energy of wind.
2. Water erosion: Water erosion is caused by the kinetic energy of rain falling of the soil surface and by the mechanical force of rainoff.
3. Gravity erosion: Mass movement of soil occur on step slop under the influence of gravity.The process involves the transfer of slop-forming materials from higher to lower ground due to self weight.

Posted by Soumya Vashishtha 4 years, 6 months ago (11370925)

CBSE > Class 10 > Mathematics

1 answers

Sia ? 4 years, 6 months ago (6945213)

Let the fixed charge be Rs x and

The charges for per km be Rs y

Therefore

x + 12 y = 89 ......... eqn 1

And

x + 20 y = 145 ........eqn 2

1 - 2

x + 12 y - x - 20 y = 89 - 145

8 y = 56

y = 7

Therefore x + 20 (7) = 145

x + 140 = 145

x = 5

Now , for 30 km

x + 30 y = 5 + 30 * 7

= 5 + 210

= 215

Acids react with most metals to form a salt and hydrogen gas. As discussed previously, metals that are more active than acids can undergo a single displacement reaction. For example, zinc metal reacts with hydrochloric acid, producing zinc chloride and hydrogen gas.
