What kind of molecule can experience hydrogen bonding?
A. A nonpolar molecule containing a hydrogen atom
B. A molecule with hydrogen bonded to any nonmetal
C. A molecule with hydrogen bonded to O, N, or F
D. Any polar molecule containing a hydrogen atom
Answer:
Answer is C
Explanation:
C - A molecule with hydrogen bonded to O, N, or F
A molecule with hydrogen bonded to O, N, or F can experience hydrogen bonding. Therefore, the correct option is option C.
A hydrogen atom is attracted to another electronegative atom in a neighbouring molecule when it is connected to a strongly electronegative atom (O, N, or F). This attraction is more powerful than the usual dipole-dipole interactions between polar molecules.
The enormous electronegativity differential between hydrogen and the highly electronegative atom causes hydrogen bonding. The electronegative atom attracts the shared electrons in the covalent link, causing the hydrogen atom to gain a partial positive charge.

8. The following system contains 20.0 psi each of gases A and B in the end bulbs with an evacuated bulb in the centre. Both stopcocks are opened at once. What is the new overall pressure in the system?
I literally have no idea how to even start this, I know that the answer is 13.3 psi, but I don't have any clue why or how to get there.
Answer:
13.3
Explanation:
Before opening the stopcocks you have 40psi in total.
After that, those 40psi will be divided into 3bulbs, so 40/3=13.3psi for the system.

If you want to warm 3.10 g of water from 56.4 C to 82.4 C, how many calories would you need to add to the water?
Answer: 80.6
Explanation:
q = mcAt
we have the grams of water, temp change, and specific heat of water is 4.186 J/g so we can plug in our numbers to find the heat energy in joules
q = (3.10)(4.184)(82.4-56.4)
q= 337.2304 J
we need our answer to be in calories so divide our answer by 4.184 and we get 80.6 calories
The amount of calorie required to warm 3.10 g of water from 56.4°C to 82.4°C is 80.6 calories.
HOW TO CALCULATE CALORIES:
The amount of calories can be calculated by using the formula as follows:Q = m × c × ∆T
Where:
Q = amount of heat in caloriesc = specific heat capacity (J/g°C)∆T = change in temperature (°C)m = mass (g)According to this question, c = 4.184J/g°C, m = 3.10g, ∆T = 82.4°C - 56.4°C = 26°CQ = 3.10 × 4.184 × 26Q = 337.23JSince 1J = 0.2390057361 calories337.23 J = 80.6calories.Therefore, amount of calorie required to warm 3.10 g of water from 56.4°C to 82.4°C is 80.6 calories.Learn more at: https://brainly.com/question/8097823?referrer=searchResults
How can the gravitational potential energy of an object be changed?
Answer:
Gravitational potential energy may be converted to other forms of energy, such as kinetic energy. If we release the mass, gravitational force will do an amount of work equal to mgh on it, thereby increasing its kinetic energy by that same amount (by the work-energy theorem).

Which chemical equation below is balanced to follow the Law of Conservation of Mass?
2 H2 + Cl2 > 3 HCl
2 H2 + 2Cl2 > 2 HCl
H2 + Cl2 > 2HCl
H2 + Cl2 > HCl
Answer:
H₂ + Cl₂ → 2HCl
Explanation:
The equation that is balanced and follows the law of conservation of mass is:
H₂ + Cl₂ → 2HCl
Based on the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but they combine with one another".
It suggests that the number of species on both sides of the expression must be the same.
For the given reaction:
H₂ + Cl₂ → 2HCl

Which manufacturing process is shown in the photograph?
A Combining
B. Separating
c. Forming
D. Conditioning
The manufacturing process shown in the photograph is a process of forming. The correct answer is option C.
Manufacturing processes refer to the series of steps or operations involved in converting raw materials or components into finished products. These processes are designed to transform the materials into the desired shape, form, or functionality.
The photograph shows that, the substance is poured in a mold to create a product of specific geometry. In this case, it is a cube. This process is known as forming processes. It includes techniques like bending, stamping, or forging, which involve shaping materials by applying pressure or manipulating them through dies or molds.
Therefore, the photograph shows the manufacturing process is a process of forming. Option C is the correct answer.

if one species of rabbit, the gene for brown fur ( B) is dominant, while the gene for black fur ( b) is recessive. One rabbit has the dominant allele for brown fur and the recessive allele for black fur. Another rabbit has two recessive alleles. If the two rabbits have offspring, what are the odds of one of the offspring having brown fur?
Answer:
1/2
Explanation:
According to this question, the gene coding for fur color in rabbits contains two alleles viz: alelle for brown fur ( B) is dominant, while the allele for black fur ( b) is recessive. This means that an heterozygous rabbit (Bb) will have brown fur.
Based on the question, one rabbit has the dominant allele for brown fur and the recessive allele for black fur i.e genotype Bb, another rabbit has two recessive alleles i.e. genotype bb. If these two rabbits cross i.e. Bb × bb, the proportion of the offsprings produces will have Bb, Bb, bb and bb genotype.
Bb is dominant, hence, 1/2 of the offsprings will be brown furred.

What is electron configuration?Electron configuration of an element describes how electrons are distributed in its atomic orbitals. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence.
Electron configuration can be written according to the following rules-
1. Aufbau Principle
2. Pauli's exclusion principle
3. Hund's rule
Electrons will be filled according to the increasing order of the energy as per the n+l rule.

Electromagnetic waves will travel the SAME SPEED (speed of light) WITHIN a medium as it does WITHOUT a medium. Question options: True False
Answer:
True
Explanation:
The speed that electromagnetic waves will travel within any medium is the same as those without a medium. The speed of electromagnetic wave is a constant and does not depend on the material of the medium.
Electromagnetic waves are waves that do not require a material medium for their propagation. They are able to pass through vacuums and mediums with particles at constant speed. It is mechanical waves whose speed is medium dependent. Mechanical waves have varying speed based on the mediums they move through.
