    6.022 * 10^22 atoms of oxygen.

    Aarti Anand 5 years, 7 months ago

    1mole of carbon dioxide =44g So, 88g of CO2 = 2 mole. Now, one mole carbon dioxide contains 32g of oxygen. So, two mole CO2 have 64g oxygen. Also 16g oxygen =1 mole 1g oxygen = 1/16 mole So, 64g oxygen =1/16*64 mole=4 mole Also, 1 mole = 6•022*10^23 atoms So, 4 mole = 4*6•022*10^23 atoms =2•4088*10^24 atoms. Thus, 88g CO2 have 2•4088*10^24 atoms of oxygen.

    32 is the right answer. To find the maximum number of electrons that can be accodated in a shell is found by the formula 2 n^2 where "n" is the quantum number. The quantum number of N shell is 4 , so 2*4^2=2*16=32.

    Mg=24u O=16u In, MgO, Atomic mass of MgO=24*1+16*1=40u Let the ratio be 3x:2x According to question. 3x=24g 2x=16g

    1Thank You

    Gungun Ghosh 5 years, 7 months ago

    We know that Mg and O combine in the ratio of 3:2 Mg:O = 3:2 Now 24g of Mg is given. Let the mass of O be X. 3:2 = X:24 Cross multiply both the sides. 3×X = 24×2 X = (24×2)÷3 = 48 ÷ 3 =16g Therefore 16g of O is required to completely mix with 24g of Mg.

    The increase in the percentage of the gases which prevent the escape of heat from the earth, which cause the average temperatures to increase worldwide is called greenhouse effect.

    Heat is trapped by glass, and hence the temperature inside a glass enclosure will be much higher than the surroundings. This phenomenon was used to create an enclosure where tropical plants could be kept warm during the winters in colder climates. Such enclosures are called greenhouses. Carbon dioxide is one of the greenhouse gases

    Whenever  objects  fall  towards  the Earth under  the  influence  of  gravitational  force  alone,  the  objects are said to be in a state of free fall.
    During  free  fall, there  is  no  change  in  the  direction  of  motion  of  the  object,  but  the  magnitude  of  the velocity of the falling object changes. 
    The  value  of ‘g’ is  maximum  on  the  surface  of  the Earth;  it  decreases  as  we  move  above  or  go beneath the surface of the Earth.
    The force with which an object is attracted towards the Earth is the weight (W) of the object. It is equal to the product of mass (m) and acceleration due to gravity (g).
    W = mg

    Meghna Thapar 5 years, 7 months ago

    The mitochondria are tiny bodies of varying shapes and size. Each mitochondria is bounded by a double membrane envelope. Outer membrane is porous. The inner membrane is thrown into folds. These folds are called cristae and are studded with small rounded bodies known as F1 particles or oxysomes. The interior cavity of the mitochondria is filled with a proteinaceous matrix which contains a few small-sized ribosomes, a circular DNA molecule and phosphate granules. Mitochondria are sites of cellular respiration
