Answer:

The effect is the acid rain.

Explanation:

The effect that the pH of smoke has on water in the atmosphere is the generation of acid rain. Acid rain is the precipitation of particles that have been acidified as a result of air pollution. Acidity is measured with the pH scale and ranges from 0 to 14, with 0 being the most acidic and 14 being the most alkaline or basic. A pH of 7 corresponds to a neutral solution.

In places without contamination, the rain has a pH value between 5 and 6. When the values are lower than that parameter, the rain is considered acidic. These pH values are due to the fact that some gases (especially nitrogen oxides and sulfur dioxide) react to contact with air humidity and transform into sulfuric acid, nitric acid and hydrochloric acid. These acids are located in the clouds and the rain produced by these clouds is acid rain.

The ph of smoke disrupts the natural ph of water( which is 7, the neutral ph) in the atmosphere causing it to become acidic . This is dangerous as it will also have effects on rain and soil ph.

Ethanol has a Kb of 1.22 °C/m and usually boils at 78.4 °C. How many mol of an nonionizing solute would need to be added to 48.8

Galina-37 [17]

Answer:

0.272 mol

Explanation:

∆Tb = m × Kb

∆Tb = 85.2°C - 78.4°C = 6.8°C

Kb = 1.22°C/m

mass of ethanol = 48.80 g = 48.80/1000 = 0.0488 kg

Let the moles of non-ionizing solute be y

m (molality) = y/0.0488

6.8 = y/0.0488 × 1.22

y = 6.8×0.0488/1.22 = 0.272 mol

Calculate the enthalpy change for the thermite reaction: 2Al(s)+Fe2O3(s)→2Fe(s)+Al2O3(s), ΔH∘rxn=−850 kJ when 12.0 mol of Al und

Answer: The enthalpy of the reaction for given amount of aluminium will be $-51.0\times 10^2kJ$

Explanation:

We are given:

Moles of aluminium = 12 moles

For the given chemical reaction:

$2Al(s)+Fe_2O_3(s)\rightarrow 2Fe(s)+Al_2O_3(s);\Delta H^o_{rxn}=-850kJ$

By Stoichiometry of the reaction:

If 2 moles of aluminium produces -850 kJ of energy.

Then, 12 moles of aluminium will produce = $\frac{-850kJ}{2mol}\times 12mol=-5100kJ$ of energy.

Converting this into three significant figures, we get:

$\Rightarrow -5100kJ=-51.0\times 10^{2}kJ$

Thus, the enthalpy of the reaction for given amount of aluminium will be $-51.0\times 10^2kJ$

A 250.0 mL sample of air at 100.0 K is warmed to 200.0 k at constant pressure .What is the volume of the air sample at the new t

hoa [83]

Answer:

500.0 mL

Explanation:

From Charles’ Law, we know that

$\frac{V_{1} }{T_{1} }= \frac{V_{2} }{T_{2 }}$

We can solve this equation to get

$V_{2} = V_{1} \times \frac{ T_{2}}{ T_{1}}$

$V_{2} = \text{250.0 mL} \times \frac{\text{200.0 K}}{\text{100.0 K}} = \textbf{500.0 mL}$

How does mg2+ block the effect of extracellular calcium on neurotransmitter release?

svetlana [45]

Magnesium is a strong anode than calcium. So, Mg will be oxidized into Mg2+. So instead of having Ca being the reducing agent, Mg will takes its place. That's how the "Blocking" occur.
Without Ca2+, no neurotransmitter was released because the exocytosis of the synaptic vesicles is dependent upon Ca2+.
So, when magnesium is added to the extracellular fluid it blocks the calcium channels and inhibits the release of neurotransmitter.

A good place to start when evaluating scientific evidence is to

slava [35]

First of all scientific evidence is anything that is gathered using the scientific method that supports a hypothesis can be considered. According to me, a good place to start evaluating is to look at whether the evidence was collected using good scientific principles.

Good luck :)
