D. Matter forms when particles chemically bond together.
E. Matter includes both elements and compounds.

Answers

The answer is C for matter is made up of atoms that can turn into those three stages

Answer:

Matter is anything that takes up space and has mass. Mass is the stu that matter is made of, or the amount of particles in a substance or object. Matter has physical and chemical properties and can undergo physical and chemical changes

Answers

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.

Answers

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.

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 .

Are crystals of different soluble solids similar?​

Answers

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.

Crystals of different soluble solids are not similar as they do not have definite crystals.

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 the empirical formula of a molecule containing 65.5% carbon, 5.5% hydrogen, and 29.0% oxygen

Answers

Carbon(C):
number of moles= mass/molar mass(Mr)
=65.5/12
=5.5 moles

Hydrogen(H):
number of moles=mass/molar mass (Mr)
=5.5/1
=5.5 moles

Oxygen (O):
number of moles = mass/molar mass (Mr)
=29.0/16
=1.8 moles

EF= lowest number of moles over each of the elements

So,
C= 5.5/1.8 = 3
H= 5.5/1.8 = 3
O= 1.8/1.8 = 1

Therefore Emperical formula= C3H3O

A car travels 76 km/hr for 11 hours. How far did the car travel in this time period (in kilometers)?

Answers

Answer:

836 km

Explanation:

76*11=836

Answer:

836km

Explanation:

76km/hr = 76×1000÷3600= 190/9 m/s

11hours =39600 s

Distance=speed×time

Distance=190/9 × 39600= 836,000m

So distance is 836,000m or 836 km.

This method is possible only if body is moving linearly and the velocity is constant.

If there is uniform acceleration use Newton's laws of motion.

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.
