An isolated H atom<span> has </span>one<span> electron. So the H </span>atom in sulfuric acid<span> has a </span>formal charge<span> of zero. The O</span>atom<span> next to H "owns" the four lone pair electrons, plus </span>one<span> electron from the O-H bond, plus </span>one atom<span>from the O-S bond. This makes a total of six electrons</span>

What is the concentration of the unknown h3po4 solution? the neutralization reaction ish3po4(aq)+3naoh(aq)→3h2o(l)+na3po4(aq) -g
hjlf
First, we need to get moles of NaOH:

when moles NaOH = volume * molarity 

                                  = 0.02573L * 0.11 M

                                 = 0.0028 moles 

from the reaction equation:

H3PO4(aq) + 3NaOH → 3 H2O(l) + Na3PO4(aq)

we can see that when 1 mol H3PO4 reacts with→ 3 mol NaOH

 ∴ X mol H3PO4 reacts with → 0.0028 moles NaOH

∴ moles H3PO4 = 0.0028 mol / 3 = 9.4 x 10^-4 mol

now we can get the concentration of H3PO4:

∴[H3PO4] = moles H2PO4 / volume

               = 9.4 x 10^-4 / 0.034 L

               = 0.028 M

Answer:

Calcium

Explanation:

The symbol for the element with a mass number of 27 is actually Al for Aluminum instead of Co for Cobalt. Mass number refers to atomic mass, not atomic number.

Aluminum has an atomic mass of 26.982 or 27.

The letters to unscramble are I, M, C, Al, U, and C.

The mystery element is Calcium.

Hope that helps.

Which best evaluates the following statement: It's greener to wash dishes by hand than to use a dishwasher?
Volgvan

<span>It is true that energy efficient dishwasher is a water and energy saver than washing dishes by hand. A star-rated dishwasher uses 4 gallons of water in each cycle compare to a kitchen faucets who pumps out 2.5 gallons of water per minute. To conserve water, the accumulated dishes and cookware must be stack properly in a dishwasher before running a cycle. As to conservation of energy, people tend to use warm water to wash the dishes by hand and heating of water cost much, while in a dishwasher, energy-saving tips such as running a light cycle and turning off heating drying option will mark down your energy consumption. Therefore, the use of dishwasher is a much greener idea. </span>
