Answer: Electronegativity increases across a period.  

Explanation:

Electronegativity is defined as ability of an atom to attract shared pair of electrons in a bond toward itself.

Electronegativity increases across the period because when we move across the period from left to right numbers of protons and electrons are increased. By increase in number of protons ,nuclear charge also increases due to which electrons present in an atom are strongly attracted towards the nucleus. And due to presence of strong nuclear charge shared pair of electrons in a bond are also attracted towards nucleus of an electronegative atom.

olchik [2.2K]

Answer:

During photosynthesis SOLAR enerrgy is transformed into CHEMICAL energy.

Explanation:

In nutrition, green plants manufactures their own food which they use for both energy and growth. This is called an autotrophic mode of nutrition.

Therefore, photosynthesis is an autotrophic nutrition in which plant can build sugar by taking carbon dioxide from air and water from the soil. For the synthesis of sugar like glucose, carbon dioxide provides carbon

and oxygen whereas water molecules provide hydrogen. The plant builds sugar molecules from these simple compounds. Enzymes needed for this purpose are present in the cells and energy is trapped by chlorophyll from sunlight. This process is summarised in the equation below:

Sunlight (solar)

6CO2 + 6H2O--------------------> C6H12O6 + 6O2

From the equation, Carbon dioxide, water and sunlight (SOLAR energy) is the raw materials needed to produce Glucose and oxygen (CHEMICAL energy) as by products.

The volume occupied by a gas at STP is 250 L. At what pressure (in atm) will the gas occupy 1500 L, if the temperature is consta
Dennis_Churaev [7]

Answer:

6 atm

Explanation:

Using the formula P1V1=P2V2

P1= Initial Pressure

V1= Initial Volume

P2= Final Pressure

V2= Final Volume

And knowing that at stp gas will always be at 1 atm

250L(P2) = 1500

P2= 6 atm
