Explanation:

For one hurricane to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.

Answer:

0.055M

Explanation:

Using the formula as follows:

CaVa = CbVb

Where;

Ca = concentration of acid (M)

Cb = concentration of base (M)

Va = volume of acid (mL)

Vb = volume of base (mL)

According to the information given in this question, Ca (HCl) = ?, Cb (NaOH) = 0.150, Va (HCl) = 86.30mL, Vb (NaOH) = 31.75mL

Using CaVa = CbVb

Ca = CbVb ÷ Va

Ca = (0.150 × 31.75) ÷ 86.30

Ca = 4.7625 ÷ 86.30

Ca = 0.055M

Explanation:

Answer: The specific heat capacity of the unknown metal given is [tex]0.466 J/g^{o}C[/tex].

Explanation:

Given: Mass = 225 g

Change in temperature = [tex]13^{o}C[/tex]

Heat energy = 1363 J

The formula used to calculate specific heat is as follows.

[tex]q = m \times C \times \Delta T[/tex]

where,

q = heat energy

m = mass of substance

C = specific heat

[tex]\Delta T[/tex] = change in temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times \Delta T\\1363 J = 225 g \times C \times 13^{o}C\\C = \frac{1363 J}{225 g \times 13^{o}C}\\= 0.466 J/g^{o}C[/tex]

Thus, we can conclude that the specific heat capacity of the unknown metal given is [tex]0.466 J/g^{o}C[/tex].

Answer: The balanced chemical equation is [tex]2NaNO_{3}(s) + Heat \rightarrow 2NaNO_{2}(s) + O_{2}(g)[/tex] and it is a decomposition chemical reaction.

Explanation:

A chemical reaction in which single compound is decomposed into two or more species is called a decomposition reaction.

For example, [tex]NaNO_{3}(s) + Heat \rightarrow NaNO_{2}(s) + O_{2}(g)[/tex]

As the compound [tex]NaNO_{3}[/tex] is decomposing to given two different substances. So, it is a decomposition reaction.

Here, the number of atoms on reactant side are as follows.

The number of atoms on product side are as follows.

To balance this equation, multiply [tex]NaNO_{3}[/tex] by 2 on reactant side and multiply  [tex]NaNO_{2}[/tex] by 2 on product side. Therefore, the equation will be rewritten as follows.

[tex]2NaNO_{3}(s) + Heat \rightarrow 2NaNO_{2}(s) + O_{2}(g)[/tex]

Here, number of atoms on reactant side are as follows.

The number of atoms on product side are as follows.

Hence, this equation is balanced.

Thus, we can conclude that the balanced chemical equation is [tex]2NaNO_{3}(s) + Heat \rightarrow 2NaNO_{2}(s) + O_{2}(g)[/tex] and it is a decomposition chemical reaction.

Explanation:

If you attempted to pry open a locked window with a screwdriver, the screwdriver would leave a tool mark on the window and windowsill.

The impressions made by a tool when it comes in contact with an object are called as tool marks. These tool marks exhibit a variety of impressions depending upon the type of tool, its shape and its use. They are classified into different types depending upon the force with which they are made.

The study of tool marks is very useful in forensic science which includes information about the analysis of tool marks at the crime scene and in the laboratory, the interpretation and assessment of challenges for examination and interpretation and also the way in which tool mark evidence can be presented in a courtroom.

here's your solution

==> distance covered = 6 km

==> time taken = 30 min

==> time in hour = 30/60 = 1/2hr

= speed = distance/time

==> speed = (6)/(1/2)

==> speed = 12 km/hr

hope it helps

When a dog run 6 km in 30 minutes then dogs average speed will be 12 km/h.

The average speed of something is computed by dividing the number distance travelled by the total time it took to travel that distance. Average speed can be determined by the formula:

V=d/T

where, V is average speed , d is distance and T is time.

It is given that , d= 6 km and T= 30 minutes(0.5 h).

Calculation of average speed is show below:

Now, puts the value of given data in average speed formula.

Average speed(V )= 6/ 0.5 = 12 km/h

Answer:

Fe2O3 + C → 2Fe + CO3

Explanation:

The unbalanced equation given in this question is as follows:

Fe2O3 + C → Fe + C03

To balance this equation, one should ensure that the number of atoms of each element on both sides of the equation is equal. The balanced equation is as follows;

Fe2O3 + C → 2Fe + CO3

N.B, there are;

- 2atoms of Fe on both sides

- 1 atom of C on both sides

- 3 moles of O on both sides
