Explanation:
Both have the same temperature, but the large bowl of soup has more thermal energy than the small mug because there is more matter present in the bowl.
The temperature of both the bowl is same , but the thermal energy of large bowl is more than the thermal energy of small bowl.
What is thermal energy?Thermal energy is defined as the energy of an object or system due to the movement of its molecules and atoms. It is produced with rise in temperature.
It is also defined as internal energy present in a system in the state of thermodynamic equilibrium by virtue of its temperature.
Thermal energy is also known as heat energy.
Thermal energy is directly proportional to mass of the object.
Thermal energy sources include natural gas, coal, and oil, as well as solar, heat pump electric, and geothermal heat.
Thus, the temperature of both the bowl is same , but the thermal energy of large bowl is more than the thermal energy of small bowl.

Find the number of protons, neutrons, and electrons for carbon-12, carbon-13, and carbon-14 respectively.
Answer:
A neutral atom of Carbon-12 contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 (six protons plus six neutrons).
Carbon-13 (13C) is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons and six electrons.
Neutral carbon-14 contains six protons, eight neutrons, and six electrons; its mass number is 14 (six protons plus eight neutrons).
Hope this helps! =D
The number of electrons, protons and neutrons in carbon -12 are all 6 and in carbon-13 they are 6, 6, and 7 respectively and in carbon-14 it is 6, 6,and 8 .
What are isotopes ?Isotopes are atoms of same element with different mass numbers. Isotopes slightly differ in physical and chemical properties also. Most of the element in periodic table have isotopes however, not all of them are stable and abundant.
The number electrons and protons in a neutral atom is equal. Mass number of an atom is the sum of number of protons and neutrons. In carbon -12, the number of electrons and protons and neutrons is 6 and the number of neutrons in carbon -13 is 7.
The number of electrons and protons is 6 and that of carbon- 14 is 7. Therefore, all these isotopes are having same atomic number but differ in neutrons numbers.

why does pure water not conduct electricity in terms of bonding
[tex] \huge\begin{gathered} {\underline{\boxed{ \mathcal {\red{Answer}}}}}\end{gathered}[/tex]
Positive and negative ions attract each other and combine with each other to yield ionic compounds and they are separated easily to conduct electricity.
The concentration of ions in pure water is very less and is almost unionised, thus does not conduct electricity.What does mean when it asks for the smaller ion
Explanation:
mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus.

if equations are not balanced,what must you do?
If a chemical equation is not balanced it implies that either mass has been created or destroyed which is a contradiction to law of conversation of mass which states that matter can niether be created nor destroyed.
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.

S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O
In the above equation how many moles of water can be made when 75 moles of HNO3 are consumed?
Let required moles be x
[tex]\\ \sf\longmapsto \dfrac{2}{6}=\dfrac{x}{75}[/tex]
[tex]\\ \sf\longmapsto \dfrac{1}{3}=\dfrac{x}{75}[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{75}{3}[/tex]

2moles of H2O are made when 6moles of HNO3 are consumed
75 mole of HNO3 produces = [tex]\frac{2}{6}[/tex]× 75 ⇒ 25 moles of water
Limiting Reagent MethodThe limiting reagent is the reactant that is completely used up in a reaction and thus determines when the reaction stops.
S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O
6 mole of HNO3 produces = 2 moles of H₂O
1 mole of HNO3 produces = [tex]\frac{2}{6}[/tex] mole of H₂O

-If sulfuric acid (H2SO4) reacts with 29 grams of sodium chloride (NaCl), how many grams of hydrochloric acid (HCl) are produced? H2SO4 + NaCl > HCl + Na2SO4
- In the same reaction, how much salt (NaCl) is needed to produce 4.0 moles of sodium sulfate (Na2SO4)?
- In the same reaction, if you started with 100 moles of sulfuric acid (H2SO4), how many moles of hydrochloric acid (HCl) could you produce?
Explanation:
mole = mass/molar mass
mole of Nacl = mass/mm
molar mass of Nacl = Na + Cl = 23+35=58
mole of NaCl = 29/58
mole of NaCl = 0.5mol
H2SO4 + NaCl ====> HCl + Na2SO4
1. 1. 1. 1
since mole of NaCl is 0.2mol then mole of HCl is also 0.2mol since they are all in the same ratio
mole of HCl = Mole of NaCl = 0.5mol
mass of HCl = ?
molar mass of HCl = H + Cl = 1+ 35=36
mole of HCl = mass /molar mass
0.5= mass/36
mass = 0.5×36 = 18 grams

Why do solids maintain their volume and shape? cause-effect
A.) Because they vibrate
B.)because they are packet tight
C.) because they are crystalline
B.)because they are packet tight
Answer:
Because they are packet tight.
Explanation:
Solids maintain their volume and shape because they are packet tight.
A solid's particles fit closely together. The forces between the particles are so strong that the particles can not move freely; they can only vibrate. This causes a solid to be a stable, non-compressible shape with definite volume.Which group have spore- dispersing vascular plants? *

A quantity of gas has a volume of 2250 at a temperature of 45 C and a pressure of 650 torrWhat is the temperature (in °C) if the volume remains unchanged but the pressure is decreased to 565 torr?
Answer:
your answer is 769
Explanation:
i took the test lol
The pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature, according to Gay Lussac's Law. When you heat a gas, the molecules gain energy and move faster. This means more impacts on the container's walls and an increase in pressure.
The temperature at 565 torr = 276.5 K
What are gas laws?Gas laws are laws that relate a gas's pressure, volume, and temperature. Boyle's law, named after Robert Boyle, states that the pressure P of a gas varies inversely with its volume V at constant temperature, or PV = k, where k is a constant.Boyle's Law states that when the temperature and mass are both constant, the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure.Charles' law states that if the pressure remains constant, the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature.The pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature, according to Gay Lussac's Law. When you heat a gas, the molecules gain energy and move faster. This means more impacts on the container's walls and an increase in pressure.Avogadro's law states that equal volumes of different gases contain an equal number of molecules under the same temperature and pressure conditions.

Answer:
Its formula is B) XY3,also known as ammonia,because X is hydrogen and Y is nitrogen.
So,yeah the answer is B
Pls mark me as brainliest
The electronic structures of atoms X and Y are shown. X and Y form a covalent compound. The formula is XY₃. The correct option is B.
What are covalent bonds?Covalent bonds are the strongest bonds present between chemical elements. This bond is formed by sharing electrons between the elements.
Two atoms share electrons with each other and form bonds between them. They are the strongest because there is sharing of electrons between them.
There are five electrons present in the outer shell of the Y atom. There are two atoms more needed to complete the orbital of Y. There is one electron present in the X atom.
Those compounds that are formed by the covalent bond are the strongest compounds. So they are not easy to break them.
Thus, the correct option is B. XY₃.
