According to the Arrhenius theory, when a basedissolves in water it produces
(1) CO3 2– as the only negative ion in solution
(2) OH– as the only negative ion in solution
(3) NH4 + as the only positive ion in solution
(4) H+ as the only positive ion in solution

Answers

According to Arrhenius Theory of acids and bases, when a base dissolves in water, the only negative ion produced is OH-.

Therefore, (2) OH– as the only negative ion in solution is the correct answer.

When might a large volume of material have little mass

Answers

A large volume of material will have a small amount of mass when thematerial in question is gaseous or porous, and therefore has a lot ofspace within it despite taking up a large amount of space overall.

the empirical formula of a compound is NO2. it's molecular mass is 92g/mol. What is its molecular formula?

Answers

The molecular formula:
$N_x(O_2)_x$

$M_(N_x(O_2)_x)=x * M_N + x * 2 * M_O \n \nm_N=14 \ (g)/(mol) \nm_O=16 \ (g)/(mol) \n M_(N_x(O_2)_x)=92 \ (g)/(mol) \n \n92=x * 14+x * 2 * 16 \n92=14x+32x \n92=46x \n(92)/(46)=x \nx=2 \n \nN_2(O_2)_2 \Rightarrow N_2O_4$

The molecular formula is N₂O₄.

Which of the following is true in regard to ions?A. Ions can only carry positive charges.
B. An ionized atom has a number of protons that is unequal to the number of electrons.
C. A cation will hold a positive charge if it gains one or more electrons.
D. Losing one or more electrons will turn an atom into an anion.

Answers

I think the best answer for this question is B. An ionized atom has a number of protons that is unequal to the number of electrons. Atoms have a neutral charge since the number of the positively charge particles and the negatively charged particles are equal. However, when these particles are unequal a charged atom will be the result.

Answer:

B. An ionized atom has a number of protons that is unequal to the number of electrons.
