There is no proof of a “god”, but if there is one, why would the world have tornados, hurricanes, floods, poverty, wars, and etc.?

Answer:

I'm not really religious but I will take a shot looking from your perspective.

He shows that he is still acting around us by showing how powerful he is and that to remind us that he still does things on this earth and still acts around this earth.

Nitroglycerine decomposes violently according to the chemical equation below. What mass of carbon dioxide gas is produced from t

AveGali [126]

Answer : The mass of $CO_2$ produced is, 7.74 grams

Solution : Given,

Mass of $C_3H_5(NO_3)_3$ = 13.3 g

Molar mass of $C_3H_5(NO_3)_3$ = 227 g/mole

Molar mass of $CO_2$ = 44 g/mole

First we have to calculate the moles of $C_3H_5(NO_3)_3$ .

$\text{ Moles of }C_3H_5(NO_3)_3=\frac{\text{ Mass of }C_3H_5(NO_3)_3}{\text{ Molar mass of }C_3H_5(NO_3)_3}=\frac{13.3g}{227g/mole}=0.0586moles$

Now we have to calculate the moles of $CO_2$

The balanced chemical reaction is,

$4C_3H_5(NO_3)_3\rightarrow 12CO_2(g)+6N_2(g)+10H_2O(g)+O_2(g)$

From the reaction, we conclude that

As, 4 mole of $C_3H_5(NO_3)_3$ react to give 12 mole of $CO_2$

So, 0.0586 moles of $C_3H_5(NO_3)_3$ react to give $0.0586\times \frac{12}{4}=0.176$ moles of $CO_2$

Now we have to calculate the mass of $CO_2$

$\text{ Mass of }CO_2=\text{ Moles of }CO_2\times \text{ Molar mass of }CO_2$

$\text{ Mass of }CO_2=(0.176moles)\times (44g/mole)=7.74g$

Thus, the mass of $CO_2$ produced is, 7.74 grams

In a beaker, 300 grams of water at 80°C cools down to 20°C. Assume all the heat from the water is absorbed by 100 cubic meters o

scZoUnD [109]

Answer:

mass of water, mw = 300g = 0.3kg

∆Tw = (80 - 20) °C

volume of air, va = 100m³

mass of air, ma = 100g = 0.1kg

∆Ta = ?

H = mc∆T

Hw = mwcw∆Tw

Hw = 0.3*4200*60

Hw = 75600J

Hw = 75.6 kJ

All the above heat energy got absorbed by air,

that is; Ha = 75600J

since it's given that the heat was absorbed by a specific amount of volume of air

then specific capacity of volume of air is

then,

ca = Ha × density

ma temp

then,

Ha = vaca∆Ta

where, ca = volumetric heat capacity of air = 0.012kJ/m³°C

75.6kJ = 100m³ × 0.012kJ/m³°C × ∆Ta

75.6 = 1.2/°C × ∆Ta

∆Ta = 63°C

63°C is the temperature change in air.

How is increasing levels of atmospheric carbon dioxide most significantly affecting coral reefs and sea life?

SOVA2 [1]

Answer:

Through the process of condensation

Explanation:

Condensation is when gas converts to liquid. Carbon Dixide in the air will eventually convert to water and ruin the ocean water, thus affecting coral reefs. Please mark brainliest :)
