A student drops a 95g object into a graduated cylindor that has 30ml of water in it. After the object is added to the cylinder the water level reads 63ml. What is the density of the object? ​

Answers

Answer:

The answer is 2.88 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question

mass = 95g

volume = final volume of water - initial volume of water

volume = 63 - 30 = 33 mL

We have

[tex]density = \frac{95}{33} \\ = 2.87878787...[/tex]

We have the final answer as

2.88 g/mL

Which of the following is true about the picture above? What would it be?

Answers

Answer:

Container A is a solution and Container B is a colloid.

Explanation:

Container A is a solution as the tyndall efffect is not present. You cannot see the light bean through the glass.

Container B is a suspension or a colloid as you can see the beam through the glass.

The first option proposes Container A is a colloid...this is not correct

The third option is not true as the tyndall effect is only displayed in container B

The fourth option is not correct the tyndall effect is not present in container A meaning it would not be a suspension or a colloid and you can see the tyndall effect in container B indicating its not a solution

how many picoliters are in 3.16 mL

Answers

Answer:

3.16×10⁹ pL

Explanation:

Given data:

Volume in mL = 3.16

Volume in picoliters = ?

Solution:

Picoliter and milliliters are units of volume. Milliliter is greater unit than picoliter.

1 mL = 10⁹ pL

Now we will convert the 3.16 mL into pL.

3.16 mL × 10⁹ pL/ 1 mL

3.16×10⁹ pL

The Law of Conservation of Mass
In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

a. 2.50 mol of sulfur, S
b. 1.80 mol of calcium, Ca
c. 0.50 mol of carbon, C
d. 3.20 mol of copper, Cu

Answers

a) 80

b) 36

c)6

d)64

All in grams

the formula ; n= m

M

was used .

where n is moles

m is mass of a substance

M is molar mass

The mass of the substance is the product of the moles and the molar mass. The mass of sulfur = 80 gm, calcium = 72 gm, carbon = 6 gm, and copper = 201.6 gm.

What is mass?

Mass of any substance is the amount of the constituent particle it holds together and can be measured in grams. The mass has been calculated from the moles of the substance and its molar mass.

The mass of sulfur is calculated as,

Mass = moles × molar mass

= 2.50 mol × 32 g/mol

= 80 gms

The mass of calcium is calculated as,

Mass = moles × molar mass

= 1.80 mol × 40 g/mol

= 72 gms

The mass of carbon is calculated as,

Mass = moles × molar mass

= 0.50 mol × 12 g/mol

= 6 gms

The mass of copper is calculated as,

Mass = moles × molar mass

= 3.20 mol × 63 g/mol

= 201.6 gms

hydrogen atom forms an ionic bond with oxygen.

Answers

Answer: B (water molecule has a bent shape)

Explanation:

Water molecules are polar molecules because of their shape. Water molecules have one side that is positively charged due to hydrogen atom which is partially positive and the other side which is negatively charged, due to the oxygen atom.

When two molecules get close to each other the polar forces of attraction brings them close to each other. Oxygen bonds with several hydrogen atoms in the other water molecules resulting to hydrogen bonds.
