Answer :
and 
are reactants.
and 
are products.
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
In the balanced chemical reaction, the reactants and products are separated by right arrow.
The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.
When ethanol react with oxygen gas then it gives carbon dioxide and water as a product.
The balanced chemical reaction will be:
In the given balanced reaction,
and are reactants.
and are products.
The correct answer is - D. the insect touching the trigger hairs.
On this photos we have an example of an insect and a ''flesh-eating'' plant, where the insect is touching the trigger hairs of the plant's ''mouth'' and the plant quickly closes and traps the insect. All of the plants that have evolved to consume other living organism have a developed system that reacts on touch, so if an insect touches some of the parts of this system, usually a sticky liquid or hairs, it immediately reacts and closes, thus trapping the insect and starting to digest it.
Ba(NO₃)₂(aq) + Na₂SO₄(aq) → BaSO₄(s) + 2NaNO₃(aq)
Ba²⁺ + SO₄²⁻ → BaSO₄
You just need to know the amount of valance electrons in each element or you can search up “How to do lewis diagrams.”
Answer:
The molar heat of vaporization of dichloromethane is 30.8kJ/mole
Explanation:
Using Clausius Clapeyron equation
ln (P1/P2) = (ΔHvap/R) (1/T2-1/T1)
At initial temperature of Ooc , the vapour pressure is 134mmHg
Therefore T1 = 0+273 =273K
And P1 = 134mmHg
At normal boiling point of 40oC , the vapour pressure is 760mmhg
T2 = 40 +273 = 313K
P2 = 760mmHg
ln (134/760) = ΔHvap/(8.3145 J/molK)
( 1/313K - 1/273K)
ΔHvap = 30800J/mol
= 30.8kJ/mol
Therefore, the molar heat of vaporization can be calculated using
Clausius Clapeyron equation using the above steps
