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.

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

Answer:

Explanation:
NH₄+ , (CO₃)₂- , OH- , (PO₄)₃- are all examples of polyatomic ions.
What are Polyatomic ions?A covalent bound type of collection of two or more atoms or of a metal complex that can be said as behaving as a single unit and that has a net charge which is not zero is referred to as a polyatomic ion or a molecular ion.
Depending on the terminology , a polyatomic ion may or may not be referred to as a molecule. The Greek word poly- that means "many," although even ions made of just two atoms are frequently referred to be polyatomic.
A polyatomic ion may also be referred to as a radical (or less commonly, as a radical group).
The term "radical" today refers to a variety of free radicals, which are species with an unpaired electron and do not require a charge.
The hydroxide ion, which has the chemical formula OH- and is made up of one oxygen and one hydrogen atom and has a net charge of 1, is a straightforward example of a polyatomic ion.
A nitrogen atom, four hydrogen atoms, and a charge of +1 make up an ammonium ion, which has the chemical formula NH₄+.
In the context of acid-base chemistry and the production of salts, polyatomic ions are frequently helpful.
A polyatomic ion is frequently thought of as the conjugate base or acid of a neutral molecule. For instance, the polyatomic hydrogen (H₂) sulphate anion (SO₄) is the conjugate base of sulfuric acid (H₂SO₄). The sulphate anion (SO₄)₂ is created when another hydrogen ion is eliminated.

Un estudiante de noveno año decide realizar varias mezclas de compuestos quimicos y tiene un frasco rotulado con la formula quimica: MgO ¿cual es el nombre del compuesto?
Answer:
- Oxido de magnesio
Explanation:
Mg → magnesio
O → oxígeno
La unión del oxígeno (no metal) con un metal, forma el determinado óxido que se nombra como óxido de .... y el no metal.
En este caso, podemos deducir que el contenido del frasco es de óxido de magnesio, aunque viendo que hay un sólo átomo de oxígeno podemos llamarlo como monóxido de magnesio, similar al CO (monóxido de carbono).
A partir de que el magnesio sólido entre en contacto con el aire, se produce MgO de acuerdo a la siguiente reacción:

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.

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.

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.
Given,
a) zinc [Ar] 3d¹⁰4s²
b) iron [Ar] 3d⁶4s²
c) sodium [Ne] 3s¹
d) cobalt [Ar] 3d⁷ 4s²
e) silver [Kr] 4d¹⁰ 5s¹

An electron jumps down from the fourth energy level to the first energy level and releases a light wave of 10.8 nm in wavelength. Determine the energy level value for the fourth energy level for the atom
Answer:
-20.2 * 10^-18 J
Explanation:
From;
E = hc/λ
h= planks constant = 6.6 * 10^-34 Js
c= speed of light = 3 * 10^8 ms-1
λ = wavelength = 10.8 * 10^-9 m
Substituting values;
E = 6.6 * 10^-34 * 3 * 10^8/ 10.8 * 10^-9
ΔE = -1.8 * 10^-17 J
But for ground state E1=−13.6eV or -2.176 * 10^-18 J
From;
ΔE = E4 - E1
E4 = ΔE + E1
E4 = (-1.8 * 10^-17) + (-2. 176* 10^-18)
E4 = -20.2 * 10^-18 J
