Calculating for the moles of H+
1.0 L x (1.00 mole / 1 L ) = 1 mole H+

From the given balanced equation, we can use the stoichiometric ratio to solve for the moles of PbCO3:
1 mole H+ x (1 mole PbCO3 / 2 moles H+) = 0.5 moles PbCO3

Converting the moles of PbCO3 to grams using the molecular weight of PbCO3
0.5 moles PbCO3 x (267 g PbCO3 / 1 mole PbCO3) = 84.5 g PbCO3

Answer: 6 grams of lead carbonate wlll get easily dissolve in 1 L of 1.0 M H^+ solution.

Explanation:

PbCO_3(s)+2H^+(aq)\rightarrow Pb^2+(aq)+H_2O(l)+CO_2(g)

Moles of H^+ (n):

1.0 M=\frac{\text{mole of }H^+}{\text{Volume of the solution is L}}=\frac{n}{1 L}

n = 1 mole

According to reaction 2 moles of H^+ dissolves 1 mole of PbCO_3 then , 1 mole will dissolve ;\frac{1}{2}\times 1 moles of PbCO_3 that is 0.5 moles

Mass of the compund:

=Number of moles of compound × Molar mass of compound

Mass of dissolved PbCO_3:

=0.5 mole\times 267.21 g/mol=133.605 g

1 L of 1.0 M H^+ solution can dissolve 133.605 grams of lead carbonate. So, 6 grams of lead carbonate wlll get easily dissolve in 1 L of 1.0 M H^+ solution.

Why would an organism want to call attention?
adoni [48]
1. Calling for attention could mean asking for a mate, or simply marking territory.
2. The rattlesnake's rattle serves as a warning to all its prey and predators. 
3. A sweet scent for a plant attracts insects to pollinate their flowers.
4. Some may have a unique way of calling out, or weird movements. Take tropical birds for example.
5. I think it's because that the females are attracted to a certain call or movement.
6. communication is talking to each other.
7. Stimuli can induce the hypothalamus in an organism's brain to react accordingly.
8. Animals need a voice, or a call, or a maovement, or anything to get their point across. 

That was a lot of typing, but i'm done. :)

What is the period of a wave with a frequancy of 3 Hz and an amplitude off 0.01
lara31 [8.8K]

0.33 seconds is the period of a wave with a frequency of 3 Hz and an amplitude off 0.01 .

<u>Explanation:</u>

We have , period of a wave with a frequency of 3 Hz and an amplitude off 0.01 . We know that period of a wave is amount of time needed to complete one oscillation . In order to calculate period of wave we use frequency and the formula use is period = \frac{1}{frequency} . We are given that frequency = 3 Hz:

period = \frac{1}{frequency}

⇒ period = \frac{1}{frequency}

⇒ period = \frac{1}{3 Hz}

⇒ period = 0.33 seconds

Therefore, 0.33 seconds is the period of a wave with a frequency of 3 Hz and an amplitude off 0.01 .

Which is greater, the moons period of rotation or its period of revolution?
balu736 [363]
C. they are equal

This is because it takes about the same amount of time for the moon to rotate around its axis that it does to rotate around the Earth.

10 atoms of Hydrogen and 5<br> atoms of Oxygen would make<br> molecules <br> of water.
steposvetlana [31]

Answer:

No, it won't. Because water is made up of two atoms of hydrogen and an atom of oxygen (the composition of water).So now do you understand? Text me if you do/don't for more explanation. Thanks for asking
