Answer :
When an acid and a base react, the reaction is called a neutralization reaction. That's because the reaction produces neutral products. Water is always one product, and a salt is also produced. A salt is a neutral ionic compound.
Which element is malleable and ductile?
○Flourine O Gallium
O Silicon O Phosphorous
Answer:
Gallium
Explanation:
The element that is malleable and ductile is gallium.
Gallium is a metal that exhibits the properties of malleability and ductility.
The ability of a material to be hammered or rolled into thin sheets without breaking or shattering is referred to as malleability. This characteristic of gallium makes it simple to shape or flatten it under pressure without shattering.
Contrarily, ductility describes a material's capacity to be pulled into thin wires without cracking. Gallium is ductile, which means it can be bent into the shape of thin wires without breaking.
Therefore, the correct option is gallium.

is ripping paper a chemical or physical app
Answer:
physical change
Explanation:
it doesnt change it chemically
Answer:
Ripping paper is physical
Explanation:
The way you know if it is physical or not is does it change physically, any physical change
No chemical changes occurred because the chemical matter didn't change nor did the actual object, it's not like the paper turned into a hotdog so it would be physical (if that makes any sense ;))
The form of energy stored in the bonds between atoms is _____________energy. This form of energy falls into the _____________energy category.
Answer:
1. chemical 2. potential
Explanation:
energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy.Energy is found in different forms, but all energy falls into the following two categories – potential energy and kinetic energy. Potential energy is stored energy, or the energy of position. It consists of the following forms: Chemical energy is energy stored in the bonds between atoms in molecules.
The form of energy stored in the bonds between atoms is chemical energy. This form of energy falls into the potential energy category.
What is chemical energy ?The term chemical energy is defined as the energy of chemical substances that is released when they are undergo the process of chemical reaction and covert into the another substances.
The chemical energy is used to create heat and electricity along the world. Some peoples also burn these fuels on more minor scales to formed heat to keep buildings warm. They burn fossil fuels like natural gas, oil, and petroleum to produce steam to turn turbines that formed heat and electricity.
The energy stored in chemical bonds is called as chemical energy therefore, it is a form of potential energy. The examples of potential energy are the energy of water present behind a dam.
Thus, The form of energy stored in the bonds between atoms is chemical energy. This form of energy falls into the potential energy category.

Solubility of CO2 in g/100 g water
Solubility of Oz in g/100 g water
Temperature in °C
Independent Variable
Dependent Variable
pls helppp asap
Answer:
Temperature - Independent variable
The solubility of CO2 and Solubility of O2 - Dependent variable
Explanation:
There are always two variables in an experiment: Independent and dependent variables.
Independent variables are defined as the variables that can be controlled or changed to measure its effect on the dependent variable and the dependent variable is influenced by the change in Independent variables.
In the given example, the temperature is the Independent variable and the solubility of CO2 and Solubility of O2 is the dependent variable because the solubility of CO2 and O2 decreases as temperature increases.
Hence, the correct answer is:
Temperature - Independent variable
The solubility of CO2 and Solubility of O2 - Dependent variable

When you get home, you smell cookies baking. You respond by walking toward the kitchen. Many signals move through your
nervous system in this process. Which component is involved first? (1 point)
O axons in your motor neurons
axons in your sensory neurons
Odendrites in your motor neurons
O dendrites in your sensory neurons
Answer:
dendrites in your sensory neurons
Explanation:
Sensory neurons are first activated, then the stimulus is transmitted horizontally between them, spreading perception through the olfactory bulb that captures the smell of a baked cookie.
After this, the axons are activated to transmit to the motor neurons that will carry out the action of walking towards the kitchen.
What are the two laws of conservation of energy?
Answer:
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. This is particularly confusing in the case of non-conservative forces, where energy is converted from mechanical energy into thermal energy, but the overall energy does remain the same. The only way to use energy is to transform energy from one form to another.
Answer:
The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.

A. Two water molecules interact due to partial charges on the oxygen and hydrogen atoms.
B. A magnesium donates electrons and forms bonds with two chloride ions.
C. A bond forms between a hydrogen from one molecule and a nitrogen from another molecule.
D. A positive potassium ion forms a bond with a negative chloride ion.
E. A nitrogen atom shares electrons with three hydrogen atoms
Answer:
A. Two water molecules interact due to partial charges on the oxygen and hydrogen atoms
Explanation:
A covalent bond is formed when the sharing of the two electron pairs and creates a stable balance of attractive and repulsive forces. The sharing allows the atoms to attain the equivalent of the outer shell. Sharing corresponds to the stable electronic configuration.A sample of platinum has a mass of 16.1 g and a volume of 0.75 cm^3. What is the density of platinum?

When thermal energy is added to an object, what happens to the motion of the particles?
why does the reactivity of elements increase going down Group 1 from lithium to rubidium but decreases going down Group 7 from fluorine to iodine?
Answer: The reactivity of group 7 elements decreases down the group because, as you go down the group: The atoms get larger. The outer shell gets further from the nucleus. The attraction between the nucleus and electrons gets weaker, so an electron is less easily gained.
