To solve this question, think about which one of these options is a DIRECT effect of sea levels rising.

Choice A: If sea levels rise, they would start to cover up land that's at sea level, areas like beaches or coastal cities for example.

Choice B: Fossil fuels cause global warming. This is about the effects of global warming, not the causes. 

Choice C: Not relevant. It doesn't mention alternative energy at all in this.

Choice D: Again, effects, not causes (see Choice B explanation).

The correct answer is... CHOICE A

Answer:

Q.1

Given-

Volume of solution-1 L

Molarity of solution -6M

to find gms of AgNO3-?

Molarity = number of moles of solute/volume of solution in litre

number of moles of solute = 6×1= 6moles

one moles of AgNO3 weighs 169.87 g

so mass of 6 moles of AgNO3 = 169.87×6=1019.22

so you need 1019.22 g of AgNO3 to make 1.0 L of a 6.0 M solution

1. What is the function of the circulatory system? * 10 points A. Provide blood with oxygen from the air, & to get rid of ca
kifflom [539]

Answer:

B. Carry oxygen, nutrients, waste, & to fight pathogens

Explanation:

The circulatory system refers to all organs and tissues involved in carrying blood and lymph around the body.

The circulatory system carries oxygenated blood from the heart to cells and  deoxygenated blood back to the heart.

Nutrients are carried in the blood to cells in different parts of the body and waste products are also carried from cells in the blood.

White blood cells is a component of blood in the circulatory system that fights off diseases.

Commercial hydrochloric acid (HCl) is typically labeled as being 38.0 % (weight %). The density of HCl is 1.19 g/mL. a) What is
Strike441 [17]

<u>Answer:</u>

<u>For a:</u> The molarity of commercial HCl solution is 12.39 M.

<u>For b:</u> The molality of commercial HCl solution is 16.79 m.

<u>For c:</u> The volume of commercial HCl solution needed is 2.42 L.

<u>Explanation:</u>

We are given:

Mass % of commercial HCl solution = 38 %

This means that 38 grams of HCl is present in 100 grams of solution.

To calculate the volume of solution, we use the equation:

Density=\frac{Mass}{Volume}

Density of HCl solution = 1.19 g/mL

Mass of solution = 100 g

Putting values in above equation:

1.19g/mL=\frac{100g}{\text{Volume of solution}}\\\\\text{Volume of solution}=84.034mL

  • <u>For a:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

We are given:

Molarity of solution = ?

Molar mass of HCl = 36.5 g/mol

Volume of solution = 84.034 mL

Mass of HCl = 38 g

Putting values in above equation, we get:

\text{Molality of commercial HCl solution}=\frac{38\times 1000}{36.5\times 84.034}\\\\\text{Molality of commercial HCl solution}=12.39M

Hence, the molarity of commercial HCl solution is 12.39 M.

  • <u>For b:</u>

To calculate the molality of solution, we use the equation:

Molarity=\frac{m_{solute}\times 1000}{M_{solute}\times W_{solvent}\text{ (in grams)}}

Where,

m_{solute} = Given mass of solute (HCl) = 38 g

M_{solute} = Molar mass of solute (HCl) = 36.5 g/mol

W_{solvent} = Mass of solvent = 100 - 38 = 62 g

Putting values in above equation, we get:

\text{Molality of commercial HCl solution}=\frac{38\times 1000}{36.5\times 62}\\\\\text{Molality of commercial HCl solution}=16.79m

Hence, the molality of commercial HCl solution is 16.79 m.

  • <u>For c:</u>

To calculate the molarity of the diluted solution, we use the equation:

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of the concentrated solution

M_2\text{ and }V_2 are the molarity and volume of diluted solution

We are given:

M_1=6M\\V_1=5.00L\\M_2=12.39M\\V_2=?L

Putting values in above equation, we get:

6\times 5=12.39\times V_2\\\\V_2=2.42L

Hence, the volume of commercial HCl solution needed is 2.42 L.
