A block of ice has a weight of 35

1 answer:

It would be 35g because you can break the ice chunk into as many pieces as you want when you combine them back together you'll always get the same weight

Summarize the Natural Processes of weathering ,erosion, and deposition

Lena [83]

Answer:

I won’t do it in paragraph form cuz it will look very choppy but here you go:

Weathering is when the weather itself changes something, like when a metal bike gets rusty after sitting outside for a long time, or when a plant grows out of concrete.

Erosion is when something gets eroded away at. Like when something has water or wind is flowing against it so much that it changes shape. This is how canyons are made.

Deposition is when a gas turns into a solid, removing energy and skipping the liquid step (frost forming on car window)

What is the Molar Mass of Cs2SO3?

Airida [17]

Answer:

345.89 g/mol

Explanation:

To find the molar mass, find the atomic mass of all the elements from a periodic table.

Cs - 132.91 × 2 = 265.82

S - 32.07

O - 16.00 × 3 = 48.00

Now add them all together.

265.82 + 32.07 + 48.00 = 345.89 g/mol

Hope that helps.

What are the steps to measure the density of a solid?

JulsSmile [24]

Answer:

Look below

Explanation:

The formula for density is:

$Density=\frac{mass}{volume}$

Therefore in order to find the density of a solid, you must find the mass and the volume first.

To find the mass, you can use a scale.

To find the volume, you can use the water displacement method. For example, if you fill the water of a graduated cylinder to 10 mL, and then you put a rock inside, and it rises to 15 mL, then the volume (of the rock) is 15mL-10mL=5mL.

How would you prepare 1.00 L of a 0.400M solution of copper(II)sulfate, CuSO4?

Ber [7]

We need to dilute 0.400 mol of copper (II) sulfate, how do we know, how many weigh of $CuSO_4$ we have to dilute??

It's simple.

$\eta=\frac{m}{MM}$

Using a periodic table we can find the molar mass of $Cu,~~S~~and~~O$

$MM_{CuSO_4}=153.9~g/mol$

Then

$m=\eta*MM$

now we can replace it

$m=0.400*159.6$

$\boxed{\boxed{m=63.84~g}}$

Then we have to dilute 63.84 grams of copper (II) sulfate in 1 L of water to obtain a solution with 0.400M
