Answer:
See explanation
Explanation:
A dipole refers to a bond in which its two ends have opposite charges. A dipole results from a large difference in electronegativity between two atoms in a bond.
For instance, consider the bond between hydrogen and chlorine in HCl. The electronegativity of hydrogen is 2.2 while that of chlorine is 3.16. The significant electronegativity difference between the two atoms leads to a charge separation.
A partial positive charge appears on the atom that is less electronegative (hydrogen) while a negative charge appears on the more electronegative atom (chlorine).
This charge separation occurs because the shared electrons of the bond are more closely attracted to chlorine making it partially negative compared to hydrogen. A dipole moment now exists in the H-Cl bond hence the molecule is said to have a dipole.

the cl-cl bond will react more readily, because it has a
The Cl-Cl bond will react more readily because it has a lower bond energy than the C- H bond.
What is bond energy?The bond energy refers to the energy required to break the bonds that links two atoms together in a molecule. It is equal to the energy that is evolved when the bond is formed.
In comparing the Cl-Cl bond with the C-H bond, we will find out that the Cl-Cl bond will react more readily because it has a lower bond energy than the C- H bond.

Calculate: A. Mercury has a specific Heat Capacity of 0.14 J/goC. How much heat is needed to raise the thermometer temperature 15 oC to 95 oC. There is 5 g of mercury in the thermometer.
Answer:
[tex]\boxed {\boxed {\sf 56 \ Joules}}[/tex]
Explanation:
We are given the mass, specific heat, and temperature, so we must use this formula for heat energy.
[tex]q=mc \Delta T[/tex]
The mass is 5 grams, the specific heat capacity is 0.14 Joules per gram degree Celsius. Let's find the change in temperature.
ΔT= final temperature - initial temperature ΔT= 95°C - 15°C = 80°CWe know the variables and can substitute them into the formula.
[tex]m= 5 \ g \\c= 0.14 \ J/ g \ \textdegree C \\\Delta T= 80 \ \textdegree C[/tex]
[tex]q= (5 \ g )( 0.14 \ J/ g \ \textdegree C ) ( 80 \ \textdegree C)[/tex]
Multiply the first numbers. The grams will cancel.
[tex]q= 0.7 \ J/ \textdegree C(80 \ \textdegree C )[/tex]
Multiply again. This time the degrees Celsius cancel.
[tex]q= 56 \ J[/tex]
56 Joules of heat are needed.

Which example describes how the water cycle carries on energy transfer? a flooding river depositing silt on a floodplain a warm ocean current warming the air above it ocean water depositing sand particles on a shore water seeping through the soil and dissolving salts
Answer:
The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.
In an ecosystem, the water cycle carrying on energy transfer is best exhibited the example of a warm ocean current warming the air above it .
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

how much is the mass of a man if
he has to do 2500 joules of work in
climbing a tree 5 meters tall
Answer:
50kg
Explanation:
Using the formula for potential energy, which is the amount of energy due to position;
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity (10m/s²)
h = height (metres)
According to the information provided in this question, m = ?, P.E = 2500J, h = 5m
Using P.E = m × g × h
m = P.E/gh
m = 2500/(5 × 10)
m = 2500/50
m = 50kg
The mass of the man is 50kg.
what is the equivalent weight of sodium trioxocarbonate (IV) in the reaction between Hydrochloric acid and sodium trioxocarbonate (IV)?
Correct answer gets brainliest. This is urgent.
Answer:
Standard acid-base reaction in two stages:
Na2CO3 + HCl → NaHCO3 +NaCl
NaHCO3 + HCl → NaCl + CO2 + H2O
If only a small quantity of acid is added (and the overall solution remains above pH 7), the reaction would stop at stage 1 and you’d be left with an aqueous solution of sodium chloride and sodium bicarbonate. Adding more acid would lead to the bicarbonate being converted to carbon dioxide and water, with the CO2 coming out of solution as a gas and more sodium chloride being produced.
