Which type of bond will most likely be found in HBr given that the electronegativity of hydrogen is 2.20 and the electronegativity of bromine is 2.96?
an ionic bond
a metallic bond
a polar covalent bond
a nonpolar covalent bond
Answer:
C. A polar covalent bond
The most likely bond found in HBr is a polar covalent bond.
What kinds of bonds exist?Ionic bond : It is formed between metals and nonmetals and the difference in their electronegativities is higher than 1.7.Metallic bond : It is formed between metals with and the difference in their electronegativities is very small.Polar covalent bond : It is formed between nonmetals and the difference in their electronegativities is between 0.4 and 1.7.Nonpolar covalent bond: It is formed between nonmetals and the difference in their electronegativities is lower than 0.4.In HBr, both H and Br are nonmetals so the bond must be covalent. The difference in their electronegativities is:
ΔE = |EN(H)-EN(Br)| = |2.20-2.96| = 0.76
The most likely bond found in HBr is a polar covalent bond.

Are the forces on the parachutes balanced?
A. The parachutes fall at a constant speed, so the forces are balanced.
B. There is a change in motion, so the forces are balanced.
C. The parachutes fall at a constant speed, so the forces are unbalanced.
D. There is a change in motion, so the forces are unbalanced.
Answer:
When the parachute opens, air resistance becomes much greater than gravity. The forces are no longer balanced and this changes her speed.
Explanation:
Eventually the upward force of the air equals the downward force of gravity. When forces are balanced the speed remains constant.
The beakers in the picture above are labeled according to the ionic solutions they contain. What metal or metals could replace copper in the copper(II) nitrate solution?
Explanation:
When a metal replaces another metal in solution, we say such a reaction has undergone a single displacement reaction.
In such a reaction, metal higher up in the activity series replaces another one due to their position.
To known the metal or metals that will replace the given copper, we need to reference the activity series of metals.
Every metal higher than copper in the series will displace copper from the solution.
So, there metals are: potassium, sodium, lithium, barium, strontium etc.

A photon has an energy of 4.0 x 10-19 Joules. What is the frequency of the radiation?
In the electromagnetic spectrum, the energy and frequency of radiation is given as, E=hυ where frequency is 0.603 ×10¹⁵ hertz.
What is electromagnetic spectrum?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.The relation is given as,E=hυ where on substitution υ =E/h=4×10[tex]^-19[/tex]/6.626×10[tex]^-34[/tex]=0.603×10¹⁵ hertz
Thus, frequency of radiation is 0.603 ×10¹⁵ hertz.

Answer:
2.99 atm
2279.43 torr
44.07 psi
Explanation:
Torr, atms and psi all units are units of pressure.
Conversion from KPa to atm:
1 KPa is equal to 0.00987 atm. To convert from KPa to atm we will multiply the given value with 0.00987 atm.
303.9 KPa × 0.00987 atm / 1 KPa
2.99 atm
Conversion from KPa to torr:
1 KPa is equal to the 7.5006 torr. To convert from KPa to torr we will multiply the KPa value by 7.5006.
303.9 KPa × 7.5006 torr/ 1 KPa
2279.43 torr
Conversion from KPa to psi:
psi is pound per square inch. 1 KPa is equal to the 0.1450 psi. To convert from KPa to psi we will multiply the KPa value by 0.1450 psi.

What will be the mass of 9.95 liters of propane gas (C3H8) at STP?
Answer:
19.5g
Explanation:
Given parameters:
Volume of propane gas = 9.95L
Unknown:
Mass of propane gas = ?
Solution:
To solve this problem, find the number of moles first.
At STP;
22.4L of gas makes up 1 mole
9.95L of gas will have a [tex]\frac{9.95}{22.4}[/tex] = 0.44mole
So;
Mass of propane gas = number of moles x molar mass
Molar mass of propane = 3(12) + 8(1) = 44g/mol
Mass = 0.44 x 44 = 19.5g
The complete combustion of acetic acid, HC2H3O2(I) to form water, H2O(I), and CO2(g), at constant pressure releases 871.7 kJ of heat per mol of acetic acid.
Write a balanced thermochemical equation if 5.0g of acetic acid will be used in the reaction.
HC2H3O2(I) + O2 --- H2O(I) + CO2(g) H= -871.7 kJ
Answer:
HC2H3O2(I) + O2(g) ---> H2O(I) + CO2(g) ΔH= -72.35 kJ
Explanation:
We know that 5.0 g of acetic acid will contain, 5.0g/60 g/mol = 0.083 moles of acetic acid
Now from the reaction equation;
1 mole of acetic acid evolved -871.7 KJ of heat
0.083 moles of acetic acid will evolve 0.083 * -871.7 = -72.35 KJ
For 5.0 g of acetic acid, we can write;
HC2H3O2(I) + O2(g) ---> H2O(I) + CO2(g) ΔH= -72.35 kJ

Explanation:
The magma bursts through Earth's surface in the form of a volcano. Heat and pressure deep in the Earth makes some rocks change to metamorphic rock. Layers of rock get squashed and packed together and gradually harden to form sedimentary rock. The igneous rock gets broken down by weather, and the cycle begins again.

Hydrazine, N2H4, and hydrogen, H2O2, have been used as rocket propellants. They react according to the equation:
H2O2 + N2H4 → N2 + H2O
a. How many moles of N2 are formed from 0.0250 moles of N2H4? (0.0250)
b. How many moles of H2O2 are required if 1.35 moles of H2O is to be produced? (0.675)
c. How many moles of H2O are formed if 1.87 moles of N2 is produced? (7.48)
Explanation:
The equation of the reaction is;
H2O2 + N2H4 → N2 + H2O
Upon balancing the reaction, we have;
N2H4 + 2H2O2 → N2 + 4H2O
a. How many moles of N2 are formed from 0.0250 moles of N2H4?
From the equation of the reaction;
1 mol of N2H4 produces 1 mol of N2
0.0250 mol of N2H4 would produce x mol of N2
1 = 1
0.0250 = x
x = 0.0250 * 1 / 1 = 0.0250 mol
b. How many moles of H2O2 are required if 1.35 moles of H2O is to be produced?
From the equation of the reaction;
2 mol of H2O2 produces 4 mol of H2O
x mol of H2O2 produces 1.35 mol of H2O
2 = 4
x = 1.35
x = 1.35 * 2 / 4 = 0.675 mol
c. How many moles of H2O are formed if 1.87 moles of N2 is produced?
The relationship between H2O produced and N2 is;
For every 1 mol of N2 produced, 4 mol of H2O is produced
1.87 mol of N2 produced, how many moles of H2O is produced?
1 = 4
1.87 = x
x = 1.87 * 4 / 1 = 7.48 mol
The ____________________ two objects are from each other, the _____________ the force of gravity between them. fill in spaces
Answer:
Farther, lesser
Explanation:
The farther the two objects are from each other, the lesser the force of gravity between them.
The force of gravitational attraction between two bodies is inversely proportional to the distance between them.
This premised on the Newton's law of universal gravitation which states that "the gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distances between them".
So, the farther the distance, the lesser the gravitational attraction and vice versa.
Scientists say that photosynthesis and cellular respiration create a cycle that is essential to almost all life on Earth. Use your knowledge of these processes to explain how an oil spill that kills a large percentage of the photosynthetic organisms living in the ocean could affect humans.
Answer:
Explanation:
An oil spill is a catastrophic event in the environment. It can negatively affect both plants and wildlife while causing human suffering and economic losses. An oil spill needn't be on the scale of the Exxon Valdez or Deepwater Horizon disasters. The U.S. Environmental Protection Agency (EPA) estimates that 200 million gallons of used oil are disposed of improperly each year.
Spilled oil floats on the surface of the water, blocking the sunlight, from reaching the plants within the body of water. Spilled oil may also directly coat the leaves of plants -- where most of the work of photosynthesis occurs -- reducing or blocking out sunlight. Without sunlight, plants lack the energy needed to undergo photosynthesis.
An oil spill can impact photosynthesis by reducing water quality. Not only does the presence of oil directly poison the water, but the spill can kill sea life, birdlife and other wildlife that uses an aquatic habitat. A large die-off can increase bacteria levels and lower the pH of a body of water. The reduction in water quality can stress plants, essentially halting photosynthesis.
