Which law represents a balanced chemical equation?​
Montano1993 [528]

Answer:

All chemical equations goes to the law of conservation of mass which says that matter can not be destroyed nor created which means there has to be an equal amount of atoms of each element on both sides of the equation. I hope that helps, I'm learning this as well.

g The difference between an ionic bond and a covalent bond is that Select one: a. ionic bonds commonly occur between two metals
Bond [772]

Answer:

C) Covalent bonds come about because of a sharing of electrons; ionic bonds do not.

Explanation:

There are two main types of chemical bonds- covalent and ionic/electrovalent bonds.

Ionic bond: Ionic or electrovalent bonds are characterized by the transfer of electrons from electropositive atoms (metals) to electronegative atoms (non-metals). The metal atoms after donating their electrons become positively charged ions (cations) while the non-metal atoms after accepting electrons become negatively charged ions (anions). Strong electrostatic forces of attraction constitutes ionic bonds.

Covalent bond: Covalent bonds are formed by the sharing of electrons by the atoms involved in the bond; usually between atoms of comparable electronegativities or atoms of the same element. The shared electrons are contributed by each of the atoms involved in the bonding or may be contributed by only one of the atoms. In covalent bonding, molecules rather than ions are formed.

1. What type of circuit is in the diagram?<br> parallel circuit<br> series circuit
devlian [24]

Answer:

A series circuit is defined as the circuit in which a number of resistances are connected one after the other.. In a series circuit, the flow of current follows a single path.

A parallel circuit is defined as the circuit in which a number of resistances are linked across each other in such a way that one terminal of each resistance is connected to form a junction point while the remaining end is also connected to form another point.

You havent added the diagram so i cant tell you the answer, but i added the definition of each circuit, see if that helps!

Pls help! Due today.
iragen [17]

Answer:

Explanation:

% yields =  <u>experimental yields</u> / theoretical yields )x 100%

              =( 302 ÷ 320 )x 100% = 94.4 %

% error = 100% - 94.37% 5.64%

or u can use this law :

% error =(theoretical  value - experimental value )/ theoretical value) x 100%

              ( 320 - 302 )/ 320 ) x 100% = 5.64%
