Answer:

A compound is composed of at least two atoms. Each atom must be a different element. An element is composed of at least one atom. Atoms from the same element are identical. An atom is composed of at least three particles. Most atoms also have neutrons and electrons.

Explanation:

Matter is composed of small units called atoms so we can say that atom are the building blocks of matter. Atom is composed of three particles i. e. proton, neutron and electron. Proton and neutron are present in the nucleus while electron revolve in the orbits. Element is a pure substance which is made of similar atoms while compounds are made of more than one atom which combines with each other in a fix ratio by mass.

Answer:An element is made up of entirely atoms while an atom is made up of at least three particles.

Explanation:

An atom is made up of protons and neutrons which stay in the nucleus and an element is composed of entirely atoms because of the atoms charge.

What is the main sugar used by cells for energy?
butalik [34]

Answer:

The answer is GLUCOSE.

Explanation:

Glucose is the main sugar used by cells for energy. Glucose is derived from the digestion of carbohydrates. In humans, glucose is usually absorbed into the blood from the small intestine, the blood then carry the blood around the body, allowing each cell to have access to the glucose it needs.

If the quantity of glucose in the blood is more than needed per time, the body usually store the excess glucose as glycogen, the glycogen will be turned to glucose and release for cell use when the quantity of sugar in the blood is low. In the absence of glycogen, other macro nutrients such as lipids and proteins can also be converted to glucose via gluconeogenesis when the concentration of glucose in the blood is low.

The cells oxidize the glucose and convert it to energy in form of ATP, which they use to carry out their life activities.

Challenge: A chemical equation is balanced when each side of the equation includes the same number of each type of atom.
nirvana33 [79]
If the reactants are the same the equations are balance but if the reactants are not the same you have to make them balance, however if the reactants are not balance  in order to balance the equation you need to use coefficient to balance the reactants and products of particular chemical reaction.
yet for Photosynthesis the equation 
CO_2 + H_2O => C_6H_12O_6 + H_2O + O_2
Find the ugliest Compound in equation and do not balance first the repetitive Element.
A)So the ugliest one is C_6H_12O_6 and the C is not repetitive and have six atoms so there fore we multiply 6 as coefficient with carbon dioxide.
6CO₂+ H₂O → C₆H₁₂O₆+H₂O+O₂ but oxygen will get 12 atoms because is to all Carbon dioxide.
B) Then we have carbon balanced then we are going to balance Hydrogen, yet on product side it have 14 but on the reactant side it have 2 but Oxygen on product side is 9 there but on reactant side we have 1 so there fore we have to multiply water on reactant side by 12 and on product side multiply water with six and in addition multiply oxygen with 6 which land you at:
6CO₂+ 12H₂O → C₆H₁₂O₆+6H₂O+6O₂.
so we will have 24 hydrogen and 24 oxygen on both sides. 
Hope that helps you.
