Balanced chemical equation: A chemical equation in which the number of atoms of reactants are equal to the number of atoms of products is called a balanced equation.

We need to balance a skeletal chemical equation because:

i. According to the law of conservation of mass, mass (or atoms) are neither created nor destroyed in chemical reactions.

ii. It means the total mass of the products formed in chemical reaction must be equal to the mass of reactants consumed.

Tejasvini S 5 years, 2 months ago

Given that:- △ABC is an isosceles triangle and ∠ABC=90° ∴AB=BC △ABE∼△ACD(∵All equilateral triangles are similar) To find:- ar(△ACD) ar(△ABE) =? Solution:- In △ABC, Using pythagoras theorem, AC 2 =AB 2 +BC 2 AC 2 =AB 2 +AB 2 [∵AB=AC] AC 2 =2AB 2 .....(i) Now In △ABE and △ACD △ABE∼△ACD(Given), As we know that ratio of area of similar triangles is equal to the ratio of squares of their corresponding sides. ∴ ar(△ACD) ar(△ABE) = AC 2 AB 2 ⇒ ar(△ACD) ar(△ABE) = 2AB 2 AB 2 [From(i)] ⇒ ar(△ACD) ar(△ABE) = 2 1 ⇒ar(△ABE):ar(△ACD)=1:2 Hence the ratio between the area of △ABE to the area of △ACD is 1:2.

Important points for presenting a chemical reaction- 1. It must be reactant on the left side of chemical equations. 2. It must be product that form in chemical reaction on the right side of chemical equations. 3. Remember that chemical equation is the symbolic representation of chemical reaction, so it should be represented by the symbols of given reactant and product. 4. The chemical equation should be balanced i.e. no. Of same atoms on the left side of equation should be equal to the no. Of same atoms on the right side of equation. *If you follows given points you will surely get a better result *

1.to balance chemical reaction,first draw boxes around each formula do not change anything inside the boxes while balancing the equation. 2.list the no. of atoms of different elements in the unbalanced equation. 3.start balancing with the compound that contains the maximum no. of atoms. 4.it may be reactant or product. 5.

f= -4cm u=-9cm v=? . . .1/u+1/v=1/f =1/-9+1/v=1/-4 =1/v=1/-4+1/9 =1/v=-9+4/36 =1/v=-5/36 =v=-7.2cm Hence, the position of image is at distance of 7.2 cm from the mirror. Now, m=-v/u =- (-7.2/-9) m=-0.8 Since, h1=2cm h2=? m=h1/h2 - 0.8=h2/2 H2=-1.6 Hence the size of image is 1.6cm and nature of image is real and inverted.

Sakshi Jagtap 5 years, 2 months ago

h1= 2cm, u = -9cm, f = -4cm......... 1/v + 1/u = 1/f ............... 1/v = 1/f – 1/u = 1/(-4) – 1/(-9)............ = - (1/4) + 1/9 = (-9 + 4)/36 = - (5/36).............. V = - 7.2 cm........... The image is formed at a distance 7.2 cm in front of the mirror........... Again, m = - (v/u) = - (-7.2)/-9 = -0.8............. m = h2/h1 ⇒ -0.8 = h2/2 ⇒ h2 = -1.6 cm ............. So, image is 1.6 cm in size, real and inverted...........hope this helps uhh?

What is mechanism of photosynthesis? Explain clearly.

Posted by Akash K 5 years, 2 months ago

CBSE > Class 10 > Science

2 answers

Sakshi Jagtap 5 years, 2 months ago

Photosynthesis is the process by which green plants prepare their food in the presence of sunlight. Green plants utilise carbon dioxide and water to make carbohydrate. The reaction of photosynthesis can be depicted in the following equation: 6CO2+12H2O---chlorop-hyll+sunlight----------->C6H12O6+6O2+6H2O.... The process of Photosynthesis is composed of following step: (a) Absorption of light energy by chlorophyll. (b) Conversion of light energy into chemical energy (c) splitting of water molecules into hydrogen and oxygen. (d) Reduction of carbon dioxide to form carbohydrate These steps need not take place one after another immediately. For example; desert plants take up carbon dioxide at night to make an intermediate. During daytime. they make carbohydrate. After photosynthesis, carbohydrate is converted into starch and starch is stored in different plant organs......hope this helps uhh?

Terrestrial organisms breathe by using atmospheric oxygen whereas aquatic organism take oxygen dissolved in water. A terrestrial animal has over an aquatic animal with regard to obtaining oxygen for respiration. It’s because the air in the atmosphere contains the maximum amount of oxygen.

Oxygen level is high in the atmosphere when compared to oxygen in water. Aquatic animals have only dissolved oxygen in water which is in minimal amount. Hence, terrestrial animal has over an aquatic animal with regard to obtaining oxygen for respiration.
