The correct answer is - tropical wet.

The tropical wet climate conditions are the ones that will enable the quickest chemical weathering of the granite, sandstone, and shale. That is due to the constant heat, high humidity, and daily rain pours.

Hope this helps :D

The correct answer is - tropical wet.

The water from the rain, and the intense humidity caused by the heat, will interact with the rocks and will be altering their surface with the chemical properties it posses.

In a very small period of time, the rocks will start to be weathering, change their shape, and lose layers.

Liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 97. g of octane is mi

zhannawk [14.2K]

Answer: 61 grams

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles of octane}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{97g}{114g/mol}=0.85moles$

$\text{Number of moles of oxygen}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{150g}{32g/mol}=4.69moles$

The chemical equation for the combustion of octane in oxygen follows the equation:

$2C_8H_{18}+25O_2\rightarrow 16CO_2+18H_2O$

By stoichiometry of the reaction;

25 moles of oxygen react with 2 moles of octane

4.69 moles of oxygen react with= $\frac{2}{25}\times 4.69=0.37$ moles of octane

Thus, oxygen is the limiting reagent as it limits the formation of product and octane is the excess reagent.

25 moles of oxygen produce 18 moles of water

4.69 moles of oxygen produce= $\frac{18}{25}\times 4.69=3.38$ moles of water.

Mass of water produced= $moles\times {\text{Molar mass}}=3.38\times 18g/mol=61g$

The maximum mass of water that could be produced by the chemical reaction is 61 grams.

What is the temperature change if 400 J of energy is added to 10 grams of water

Gemiola [76]

The temperature change if 400 J of energy is added to 10 grams of water is 9.57°C.

<h3>How to calculate temperature change?</h3>

The temperature change of a calorimeter can be calculated using the following expression:

E = mc∆T

Where;

E = energy in joules
m = mass
c = specific heat capacity = 4.18J/g°C
∆T = change in temperature

400 = 10 × 4.18 × ∆T

400 = 41.8∆T

∆T = 400/41.8

∆T = 9.57°C

Therefore, the temperature change if 400 J of energy is added to 10 grams of water is 9.57°C.

If the atomic number of an element is 8 and the mass number is 16, the number of neutrons in an atom of that element is what? (s

Serjik [45]

Answer:

Explanation:

Atomic number tells us the number of protons in an element. Mass number is the total amount of mass in an atom, and it comes from the sum of the mass of protons and neutrons, which are both considered to have a mass of 1 amu.

If the total mass is 16amu and 8amu comes from the 8 protons, the remaining mass comes from neutrons.

16 - 8 = 8
