Answer:
True statements are 2, 4, 5
Explanation:
They can be broken down by chemical means because we need to break chemical bonds between two (or more) atoms.
They are pure substance because one can't separate them by physical means.
When one separate compounds on two (or more) substances, there are two (or more) different species and they all act differently.
The answer is A it's a basic because once you add another substance to a neutral it either becomes acidic or basic. this one becomes basic because the hydroxide ion concentrate increased.
Answer:
0.250 mol Mg²⁺
0.500 mol Cl⁻
Explanation:
Magnesium chloride (MgCl₂) dissociates into ions according to the following equilibrium:
MgCl₂ ⇒ Mg²⁺ + 2 Cl⁻
1 mol 1 mol 2 mol
1 mol of Mg²⁺ and 2 moles of Cl⁻ are formed per mole of MgCl₂. If we have 0.250 mol of MgCl₂, the following amounts of ions will be formed:
0.250 mol MgCl₂ x 1 mol Mg²⁺/mol MgCl₂= 0.250 mol Mg²⁺
0.250 mol MgCl₂ x 2 mol Cl⁻/mol MgCl₂= 0.500 mol Cl⁻
a) 3 molecule of carbon dioxide (CO2) - 3 carbon atoms
b) 6 molecule of 3 - PGA - 18 carbon atoms ( 3 cabon atoms in 1 3 PGA molecule)
c) 6 molecule og G3P - 18 carbon atom ( 3 carbon atoms in G3P molecule )
d) 5 molecules of G3P - 15 carbon atom
e) 3 molecule of R5P - 15 carbon atoms ( 5 carbon atom of R5P olecule )
f) 3 molecule of RuBP - 15 carbon atoms ( r carbon atom of RuBp molecule )
