Explanation:
10.0 J of energy is required to increase the temperature of 1 g of water by 10oC. What is this value in calories? In kcal?
10 J = 2.39 cal = 2.39 x 10⁻³ kcal
Further explanationThe joule is one unit of energy. energy itself can be expressed in units such as calories, BTU, kg⋅m²s⁻²
An example of energy calculation is the calculation of heat in heat transfer
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
10 J if we convert into calories and kcal
[tex]\tt 1~J= 0.239~cal\\\\10~J=2.39~cal\\\\2.39~cal=2.39\times 10^{-3}~kcal[/tex]

Two atoms in the same molecule are linked together by a
chemical ______
Answer: Chemical bond. Two atoms in the same molecule are linked together by a chemical bond. Write "bond" in the blank.
Two atoms in the same molecule are linked together by a chemical bond.
What is chemical bond ?A chemical bond is defined as the formation of a chemical compound by the union of two or multiple atoms, ions, or molecules, the firmness can be evaluated by the type of its chemical bond.
Ionic Bond is a type of chemical bond where relocation of electrons from one atom to alternative atom, one atom creates a negative charge called as anion while another atom creates a positive charge called cation.
The covalent bond defines the distribution of electrons among atoms, it can be either polar or non polar in nature and the electrons are united unevenly in polar covalent chemical bonding.
Hydrogen Bonding is a fragile procedure of chemical bonding, this type of polar covalent bonding occur between oxygen and hydrogen where hydrogen develops a partial positive charge in the formation of the water.

The characteristic bright–line spectrum of potassium is produced when electrons
A) jump to higher energy levels
B) return to lower energy levels
C) are lost by neutral potassium atoms
D) are gained by neutral potassium atoms
E) are released from the nucleus
Answer: B.
Explanation:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
Hope this helps!

what is the difference between a galvanic cell and an electrolytic cell? APEX
Answer:
A. A galvanic cell generates electrical current, and an electrolytic cell uses electrical energy to cause redox reactions to occur.
Explanation:
A galvanic cell produces electrical energy through the conversion of chemical energy whereas the electrolytic cell carries out the conversion of the electrical energy/current supplied to it into chemical energy. The reaction that takes place in the galvanic cell is spontaneous which is responsible for the electrical energy that is produced. The redox reaction in the electrolytic cell is not spontaneous. Electrical energy has to be supplied to it in order to initiate the reaction.

why neon has zero valency?
Answer:
hope it helps you
Explanation:
Helium has two electrons in its energy shell, while argon and neon have 8 electrons in their valence shells. As these have maximum number of electrons in their valence shells, they do not have any tendency to combine with other elements. Hence, they have a valency equal to zero.

how to convert 12g of nitrogen gas in mole
Answer:
it takes more than 12g of nitrogen gas to make a mole
Answer:
0.86 mol N
Explanation:
To convert between grams and moles, you need the molar mass of the substance. The molar mass of nitrogen is 14.01g/mol. This is used as the unit converter.
[tex]12gN*\frac{1molN}{14.01gN} = 0.85653 mol N[/tex]
Then round the answer to the lowest number of significant figures = 0.86 mol N.

What characteristics do atoms of manganese- 55, iron-56, and nickel-58 have in common?
Answer:
same number of protons differnt number of nuetrons
Explanation:
Atoms of manganese- 55, iron-56, and nickel-58 have same number of neutrons and different number of protons.
Number of protons:It is same as the atomic number of an element.
Number of Neutrons:It is the difference between the mass number and atomic number or number of protons.
Manganese- 55:No. of protons = 25
No. of neutrons = 30
Iron-56:No. of protons = 26
No. of neutrons = 30
Nickel-58:No. of protons = 28
No. of neutrons = 30
Thus, the number of neutrons in all the atoms is same i.e. 30.
