We’ve all heard of acid rain and its impact on the environment, the infrastructure, like roads and buildings, and on humans. If

basic rain was a commonly occurring form of precipitation, what impact do you think it would have on the environment, the infrastructure, and on humans? Would it be more detrimental than or not as detrimental as acid rain? Explain your reasoning.

It would be more beneficial than acid rain because it is non-corrosive. Its pH is neutral. It would help to dilute acid and alkaline materials and would wash away impurities. Animals, including humans, can drink pure water, but acid rain is harmful. Plants and the soil can accept pure water which aid in supplying plants with water they can absorb directly, and water can dissolve certain nutrients that can then be more readily absorbed by plants, vegetation and microbes living in the soil. Pure water can be stored (reservoir) without the need for filtering or purifying, so reducing costs in providing drinking water. Pure water is part of the natural cycle. It evaporates leaving no deposit.

How many moles are there in 2.00 x 1023 molecules of LiOH?​
Tanya [424]

Answer:

Moles de LiOH= 0.33212 Moles

Explanation:

1 Mol of LiOH -->6.022*10^23 molecules of LiOH

therefore

2*10^{23}~molecules ~of~LiOH=\frac{2*10^{23}}{6.02*10^{23}}Moles~of#LiOH

Write the formula for the polyatomic ion in fe(hco3)3. express your answer as an ion.
Juliette [100K]
Ions can be atomic or molecular. If an atom contains either positive or negative charge it said to be atomic cation or atomic anion.

When a molecule carry positive or negative charge it is called as polyatomic cation or polyatomic anion. Generally charged or ionized molecules are called as polyatomic ions.

In given question Fe(HCO₃)₃ ionizes as follow,

                         Fe(HCO₃)₃    →    Fe³⁺  +  3 HCO₃⁻

The Ions produced are Fe³⁺ and HCO₃⁻. Fe³⁺ is said to be atomic (Ferric) ion and HCO₃⁻ (Bicarbonate) is polyatomic ion or molecular ion.

ale4655 [162]

Answer:

The answer is "6.52 kg and 13.1 kg"

Explanation:

For point a:  

Actual\ yield = 6.52 \ kg\\\\Percent \ yield= 66\%\\\\Percent \ yield = \frac{Actual \ yield}{Theoretical\ yield} \times 100 \%\\\\Theoretical\ yield \ of \ MnO_2 = \frac{Actual \ yield}{Percent \ yield} \times 100\%\\\\=\frac{6.52 \ kg}{66 \%} \times 100\% =9.88 \ kg\\\\

Equation:  

3MnCO_3 +O_2 \longrightarrow 2MnO_2 + 2CO_2\\\\

Calculating the amount of MnCO_3

= 9.88 \ kg \times \frac{1000 \ g}{1 \ kg} \times \frac{1 \ mol \ MnO_2}{86.94 \ g} \times \frac{2 \ Mol \ MnCO_3}{2 \ mol \ MnO_2} \times \frac{114.95\ g}{1 \ mol \ MnCO_3 }\times \frac{1\ kg}{1000\ g}\\\\=  13.1 \ kg

For point b:

Actual\ yield = 4.0 \ kg\\\\Percent\ yield=97.0\%\\\\Percent \ yield = \frac{Actual \ yield}{Theoretical \ yield} \times 100 \% \\\\Theoretical \ yield\  of\  Mn = \frac{Actual \ yield}{Percent \ yield} \times 100\%\\\\

=\frac{4.0 \ kg}{97.0\%} \times 100\% =4.12 \ kg

Equation:  

3MnO_2 +4AL \longrightarrow 3Mn + 2AL_2O_3\\\\

Calculating the amount of MnO_2:  

= 4.12 \ kg \times \frac{1000 \ g}{1 \ kg} \times \frac{1 \ mol \ Mn}{54.94 \ g} \times \frac{3 \ Mol \ MnO_2}{3 \ mol \ Mn} \times \frac{86.94 \ g}{1 \ mol \ MnO_2 }\\\\=  6516 \ g \\\\=6.52 \ kg\\\\

If there are 36 Strontium and 24 Phosphate, Why are there not equal numbers of cations and anions?
nalin [4]

An ion is an atom or group of atoms in which the number of electrons is not equal to the number of protons, giving it a net positive or negative electrical charge.
Due to this, anoin which is a negatively charged and is attracted to the anode (positive electrode) in electrolysis. and is considered as a proton. however Cations are positively charged and are attracted to cation ( negative electrode). its know as a electron .

So, the net positive or negative electrical charge explains the difference in the amounts of phosphate and strontium.

An ion can never have the same amount of anions and cations.
