How much heat energy, in kilojoules, is required to convert 47.0 g of ice at -18.0 C to water at 25.0 C ?

Specific Heat of Ice - 2.09 j/g * c

This is how I did it and the answer is wrong...Please check and correct me

Q = m * Cice * Change in Temp

Q = (47.0 g)(2.09 J/g*c)(43) = 4222.6 J * 0.001 kj / j = 4.22 kj

What is responsible for the blue sky?​

Answers

Answer:

The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere.

Explanation:

Answer:

sun shine

Explanation:

Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time

Use the balanced equation given below to solve the following problem; Calculate the volume in liters of CO produced by the reaction of 175 g of Sb2O3.

Sb2O3 + 3 C --> 2 Sb + 3 CO

40.3 L CO
7.81 L CO
20.2 L CO
13.4 L CO

Answers

Answer: 40.3 L

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]

[tex]\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles[/tex]

[tex]Sb_2O_3+3C\rightarrow 2Sb+3CO[/tex]  

According to stoichiometry :

1 moles of [tex]Sb_2O_3[/tex] produces = 3 moles of [tex]CO[/tex]

Thus 0.600 moles of [tex]Sb_2O_3[/tex] will produce=[tex]\frac{3}{1}\times 0.600=1.80moles[/tex]  of [tex]CO[/tex]

Volume of [tex]CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L[/tex]

Thus 40.3 L of CO is produced.

Which two changes of state can occur when a substance gains thermal
energy?

Answers

Answer:

Adding enough thermal energy to a substance can cause a change of state to occur. The change of state from a solid to a liquid is called melting. When energy is added to an ice cube, the ice particles speed up as energy is absorbed. When the particles move fast enough, the solid ice melts and becomes liquid water

3. What is found around the roots of some plants that turns nitrogen from the form we cannot use to the form we can use?

Answers

Answer:

Bacteria

Explanation:

Some plants, specifically leguminous plants form a symbiotic relationship with certain bacteria species called NITROGEN-FIXING BACTERIA in their root nodules. In this relationship, the bacteria species e.g nitrosomonas, nitrobacter etc help the plants fix atmospheric nitrogen (N2) or ammonium compounds, which are forms of nitrogen that are unusable to the plant into nitrates, a usable form.

Therefore, BACTERIA are the organisms found around the roots of these set of plants (legumes) that turns nitrogen from the form we cannot use to the form we can use.

Explanation:

What is the proper combining ratio (by mass) for carbon to oxygen in the reaction that forms carbon dioxide (CO 2)? From the data given in question 1, since 64 grams of oxygen reacts with 24 grams of carbon, the ratio must be 64 to 24, which is 2.7 parts oxygen to 1 part carbon.
