When focused light is projected onto the retina, it stimulates the rods and cones. The retina then sends nerve signals are sent through the back of the eye to the optic nerve. The optic nerve carries these signals to the brain, which interprets them as visual images.
Answer:
Vapour pressure of liquid is affected by its TEMPERATURE, TYPE OF LIQUID, ADDITION OF SOLUTES.
Explanation:
Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid. Mathematically, the vapor pressure of liquid is written as:
In (Pvap) = -ΔHvap / R * (1/T) + C
ΔHvap is the enthalpy of vaporization and it is constant for specific liquid, T is the temperature and C is a constant. Temperature therefore affect the vapor pressure of a liquid as increase in temperature can cause an increase in vapor pressure.
The type of liquid also affect the vapor pressure. If the molecules bind to each other strongly in the liquid, it increases vapor pressure to be exerted by the liquid but if the type of liquid is one with weak forces of attraction, the vapor pressure is reduced.
Addition of solute to the liquid increases the boiling temperature of liquids thereby reducing it's vapor pressure.
<u>Answer:</u> The balanced chemical equation for the decomposition of nitroglycerin is written below.
<u>Explanation:</u>
Decomposition reaction is defined as the reaction in which a single large substance breaks down into two or more smaller substances.
Every balanced chemical equation follows law of conservation of mass.
A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.
The balanced chemical equation for the decomposition of nitroglycerin follows:
By Stoichiometry of the reaction:
1 mole of liquid nitroglycerin decomposes into 12 moles of carbon dioxide gas, 10 moles of gaseous water, 6 moles of dinitrogen gas and 1 mole of dioxygen gas.
Hence, the balanced chemical equation for the decomposition of nitroglycerin is written above.
Answer:
317.7778 g
Explanation:
Given data:
Flour required for 18 cup cakes = 260 g
Flour required for 22 cup cakes = ?
Solution:
We will calculate the flour required for 1 cup cake.
260 g /18 = 14.4444 g
Fluor required for 22 cupcakes,
22× 14.4444 g = 317.7778 g
In short,
22 cupcake/18 cup cake×260 g = 317.7778 g
Answer:
Ketone
Explanation:
According to the description of the functional group attached to the hydrocarbon - the first and last of a chain of three carbons are each single bonded to 3 hydrogen (H)atoms; the center carbon is double bonded to an oxygen atom, O - it can be deduced that the functional group is a ketone group.
A ketone is a functional group with the structure R₂-C=O, where the two R are alkyl or phenyl groups which may be the same or different. The carbon in a double covalent bond with oxygen is called the carbonyl carbon. The two R groups are bonded to the carbonyl carbon in single covalent bonds.
In the hydrocarbon in this question, the two R groups are methyl groups, CH₃ bonded to the carbonyl carbon. The name of the hydrocarbon is propanone and it is a ketone molecule.
