A solution of the ionic salt Lihco3 would have 11.3 pH.
What is ionic salt ?In chemistry, salt exists as a chemical compound consisting of an ionic group of positively charged cations and negatively charged anions, which results in a combination with no net electric charge. A common example stands table salt, with positively charged sodium ions and negatively charged chloride ions.
The fragment ions in a salt compound can be either inorganic, such as chloride (Cl−), or organic, such as acetate (CH3CO−2). Each ion can be either monatomic, such as fluoride (F−), or polyatomic, such as sulfate (SO2−4).

Can you use volume alone to predict whether an object will sink or float? Explain your answer
Answer:
Can volume alone be used to predict whether an object will sink or float? -No, you need both mass and volume to find its density to see if it can float.

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.
There are 3 main ways to measure temperatures, you have Celsius, Fahrenheit, and Kelvins.
Celsius and Fahrenheit are main ways to measure heat in non-scientific terms, althought they are used sometimes when needed.
Kelvins are used for Science as they are precise and can deal with temperatures that are super hot or super cold.
The lowest temperature in Kelvins is 0 degrees Kelvin, also known as Absolute Zero. There are no temperatures above that. So the answer to your question would be Kelvins.
Write a 4-6 sentence paragraph using science vocabulary, full sentences, proper grammar, and details explaining the difference between plant cells and animal cells. Science...
Answer:
Plant cells and animal cells are both eukaryotic cells. They both have a nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, cytoskeleton and cell membrane. Only plants cells have a vacuole, cell wall and chloroplast, while animal cells have cilia, centrioles and lysosomes which plant cells don't usually have. Because of their cell walls plant cells are in rigid rectangular shapes while animal cells have looser round shapes. The main difference in their functions is that animals don't produce their own food while plan cells do.

According to the forces of attraction, the most likely state of matter of the substance mentioned is liquid.
What is matter?
Matter in chemistry, is defined as any kind of substance that has mass and occupies space that means it has volume .Matter is composed up of atoms which may or not be of same type.
Atoms are further made up of sub atomic particles which are the protons ,neutrons and the electrons .The matter can exist in various states such as solids, liquids and gases depending on the conditions of temperature and pressure.
The states of matter are inter convertible into each other by changing the parameters of temperature and pressure.According to law of conservation of matter , matter can neither be created nor destroyed only its state changes .

rutherford and JJ thompson both contributed to what we know about the structure of the atom. What experiments did they perform and how did it change what we know about the structure of the atom? Furthermore describe the structure of an atom using only two words
Answer:
J.J. Thomson's experiments with cathode-ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. I would describe the structure of an atom as the plum pudding model.

What will be the primary result of the continuation of the
geologic processes indicated at this location?
Earth's magnetic field will reverse direction.
New oceanic crust will form.
o Continental crust will be forced downward.
Earth's circumference will increase.
Answer:
B
Explanation:
new oceanic crust will form.
The formation of a new oceanic crust will be the primary result of the continuation of the geologic processes. Therefore, option (B) is correct.
What is the oceanic crust?The oceanic crust can be described as the uppermost layer of the oceanic portion of the tectonic plates. The oceanic crust is composed of the upper oceanic crust, with pillow lavas complex, and the lower oceanic crust, made of troctolite, and ultramafic cumulates.
The oceanic crust lies above the rigid uppermost layer of the mantle. The crust and the rigid upper mantle layer together compose the oceanic lithosphere.
The oceanic crust is rich in iron and magnesium and composed of mafic rocks. It is thinner than the continental crust less than 10 Km thick but it is denser with 3.0 g/cm³ as opposed to the continental crust.
The oceanic crust displays a symmetrical pattern of positive and negative magnetic lines emanating from the mid-ocean ridge.

Are crystals of different soluble solids similar?
Crystals of different soluble solids are not similar because they are amorphous and therefore do not have definite crystals.
What are crystal solids?A crystalline solid is a homogeneous solid in which the constituent particles, atoms, ions or molecules are arranged in a definite repeating pattern.
Most of the solid substances are crystalline in nature. The arrangement of particles in a crystalline solid is such that the total intermolecular force of attraction is at maximum.
Factors in which solubility depends are temperature, pH, and ionic strength.

First organisms to convert solar energy to chemical energy were the organisms which are called as cyanobacteria.
What is chemical energy?
Energy which is stored in the chemical bonds of chemical compounds is called chemical energy.Chemical energy is released during the occurrence of chemical reaction.Reactions wherein energy is given out in the form of heat is called exothermic reactions.
Chemical energy can be converted to other forms of energy like electrical energy during the process of electrolysis and to thermal energy as in the case of thermal engines.
It can also be converted to kinetic energy during explosions . It is stored in batteries, coal, biomass, food, vehicle air bags,etc.During digestion chemical energy is converted to mechanical and thermal energy.

what is neutralisation??
Answer:
Acid + Base -------> Salt + Water
Explanation:
The reaction between an acid and bases is called a neutralization reaction. The result of the reaction is salt and water. For example, when hydrochloric acid(acid) and sodium hydroxide(base) react they form sodium chloride(salt) and water. Also, heat is evolved.
Example:
HCl + NaOH ----------> NaCl + H2O
HCl is hydrochloric acid.
NaOH is sodium hydroxide which is a base.
NaCl is sodium chloride which is a salt.
H2O is water.
