The temperature of the areas surrounding Kochi before each storm was about 10°C and there was the same amount of water vapor in the air. Given this information, which storm do you predict will have the most rainfall, and why?

Answers

Answer:

Tropical storm

Explanation:

The tropical storm have the most rainfall because tropical winds will increase in strength as temperatures rise. With the increase in temperature, the tropical storms have stronger winds which leads to produce higher rainfall. There is a direct relationship between temperature and amount of rainfall. As the temperature increases, the tropical storms have stronger winds which leads to more rainfall while on the other hand, decrease in temperature decrease the strength of the tropical storm's winds that leads to lower rainfall.

The temperature given shows that the storm that will be predicted is a tropical storm.

What is temperature?

It should be noted that temperature means the degree of hotness or coldness in a body.

In this case, since the temperature of the areas surrounding Kochi before each storm was about 10°C and there was the same amount of water vapor in the air, the appropriate storm is a tropical storm.

86.30 mL of an HCl solution was required to neutralize 31.75 mL of 0.150 M NaOH. Determine the molarity of the HCI.

Answers

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

Calculate the molarity of an HCl solution if 25.0 mL of the solution is neutralized by 15.5 mL of 0.800 M NaOH. Below is the unbalanced equation: ______ HCl + _____ NaOH →____ H2O + _____ NaCl

Answers

Answer:

.496 M .

Explanation:

15.5 mL of .8 M NaOH will contain .0155 x .8 moles of  NaOH

moles of  NaOH = .0124 moles

For neutralization,  moles contained by 25 mL of HCl  = .0124

Hence molarity of HCl = .0124 / .025

= .496 M .

0.496 M is the molarity of an HCl solution if 25.0 mL of the solution is neutralized by 15.5 mL of 0.800 M NaOH.

What is molarity?

Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.

Molarity = [tex]\frac{Moles \;solute}{Volume of solution in litre}[/tex]

15.5 mL of 0.8 M NaOH will contain 0.0155 x 0.8 moles of  NaOH

Moles of  NaOH = 0.0124 moles

For neutralization,  moles contained by 25 mL of HCl  = 0.0124

Hence molarity of HCl = [tex]\frac{0.0124}{0.025}[/tex]

= 0.496 M .

Hence,  0.496 M is the molarity of an HCl solution if 25.0 mL of the solution is neutralized by 15.5 mL of 0.800 M NaOH.

If you start with 6 moles of N2 and 6 moles of H2 (meaning you won't have enough of 1 of the ingredients), how many moles of NH3 would you be able to make?

Answers

Answer:

[tex]4molNH_3[/tex]

Explanation:

Hello there!

In this case, according to the given information it will be firstly necessary to set up the chemical equation taking place:

[tex]N_2+3H_3\rightarrow 2NH_3[/tex]

We infer we need to calculate the moles of NH3 by using both of the moles of N2 and H2 at the beginning, in order to identify the limiting reactant:

[tex]n_{NH_3}=6molN_2*\frac{2molNH_3}{1molN_2}=12molNH_3\\\\ n_{NH_3}=6molH_2*\frac{2molNH_3}{3molH_2}=4molNH_3\\[/tex]

Thus, since hydrogen yields the fewest moles of ammonia, we conclude that we are just able to yield 4 moles of NH3.

Given the balanced equation representing a reaction:
H2SO3 + H2O « H3O+ + HSO3-
According to one acid-base theory, the H2SO3 molecules act as (AKS 5g)

Answers

Answer:

An acid because they donate H^+ ions

Explanation:

Let us look at the equation again;

H2SO3 + H2O « H3O+ + HSO3-

An acid donates hydrogen ion while a base accepts hydrogen ion. Hence, we have to look at which species that acted as hydrogen ion donors or acceptors.

We can clearly see that H2SO3 acted as a hydrogen ion donor while H2O acted as a hydrogen ion acceptor.

Thus, H2SO3  acted as an acid by donating hydrogen ions.

Calculate the specific heat capacity of the unknown metal given the

B.1.02j/gC
C.0.96 j/gC
D.2.14 j/gC

Answers

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].
