Answer:

1. A. Tornado

2. A. High cumulonimbus

3. A. Air pressure differences over the ocean cause fast, spinning winds.

4. C. Both form when warm air rises, then cools quickly to form clouds.

5. B. False

6. A. Tornado

Explanation:

  • A tornado is a column of air with high angular velocity whose lower end is in contact with the earth's surface and the upper end with a cumulonimbus cloud. It is short and short in duration, ranging from seconds to over an hour and destroying what is in its path on a narrow path.
  • Storm clouds have their origin in the cumulus type. They are the ones that are isolated and that look like a white cotton ball.

If it continues to grow, its upper part will be rounded and form like a small bald spot, called cumulonimbus calvus. Now they are associated with huge waterspouts, but without an electrical device. When lightning and thunder appear, we will have reached the mature phase of the storm and there is talk of cumulonimbus capillatus. Its upper part resembles a chapel or anvil, that is, the storm in its purest form.

  • Hurricanes are formed by the accumulation of thunderstorms that move over warm ocean waters. When the warm air from the storm and the ocean surface combine, they begin to rise in eddies. This generates low pressure on the ocean surface.
  • The scale with which the intensity of hurricanes is measured is known as Saffir-Simpson, and it divides them into 5 categories according to the speed of their winds and cyclonic activity, which is an abnormal increase in sea level after a storm.  The scale also calculates the damage that can occur when the hurricane makes landfall.

2. Iron reacts with superheated steam to form hydrogen gas and the oxide Fe3O4. Calculate the number of moles of hydrogen produc
vekshin1

Answer:

A 0.239mol

Explanation:

From the equation:

We were given that 10g of iron was involved in this chemical reaction

We can establish that :

3moles of Fe would produced 4 moles of Hydrogen gas

Therefore:

Number of moles of iron = mass of Fe / mloar mass of iron

Mass of Fe = 10g

Molar Mass of Fe = 55.85g/mol

Therefore, number of moles of iron= 10/55.85

Number of moles of iron = 0.179mol

3moles of Fe would produced 4 moles of Hydrogen gas

So, 0.179mol of Fe would give 0.179x4/3

The number of mole of Hydrogen gas produced is 0.239mol.

A balloon at 25°C has 30 L. What will the balloon's volume at 35°C?
anygoal [31]

The balloon's volume at 35°C : V₂=31.01 L

<h3>Further explanation</h3>

Given

T₁ = 25°C+273 = 298 K

V₁ = 30 L

T₂ = 35 °C + 273 = 308 K

Required

The new volume (V₂)

Solution

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

Input the value :

V₂=(V₁.T₂)/T₁

V₂=(30 x 308)/298

V₂=31.01 L

Which of the following best describes an empirical formula?
Monica [59]

Answer:

Option C :

a chemical formula that shows the relative number of each type of atom in a molecule, using the smallest possible ratio

Explanation:

Empirical Formula:

Empirical formula is the simplest ration of atoms in the molecule but not all numbers of atoms in a compound.

So,

Tha ration of the molecular formula should be divided by whole number to get the simplest ratio of molecule

For Example

      C₂H₆O₂ Consist of  Carbon (C), Hydrogen (H), and Oxygen (O)

Now

Look at the ratio of these three atoms in the compound

                         C : H : O

                         2 : 6 : 2

Divide the ratio by two to get simplest ratio

                          C : H : O

                         2/2 : 6/2 : 2/2

                             1 : 3 : 1

So for the empirical formula the simplest ratio of carbon to hydrogen to oxygen is 1:3:1

So the empirical formula will be

                     Empirical formula of C₂H₆O₂ = CH₃O

So, Option C is correct :

a chemical formula that shows the relative number of each type of atom in a molecule, using the smallest possible ratio
