Answer:

Cr_{2} O_{4}

Explanation:

\frac{molecular weight}{molar mass} =  \frac{168}{83.99} =  2.00

CrO_{2} x 2 = Cr_{2} O_{4}

A cup of gold colored metal beads was measured to have a mass 425 grams. By water displacement, the volume of the beads was calc
Butoxors [25]
If the volume of 425 grams was 48.0 cm³, simply divide

g/cm³ = 425 g/48 cm³ = 8.85 g/cm³

If using water in water displacement, 1 mL = 1 cm³

8.85 g/cm³ = 8.85 g/mL

This density is most closely aligned with that of B. Copper

If an element has 2 fewer protons than boron, what is its electron configuration?
REY [17]
So boron has an electronic configuration of 1S2 2S2 2P1 and the element with an atomic number of 3 is Lithium which has an electronic configuration of 1S2 2S1.

So the answer is 1S2 2S1.

Find the density of a block with a length of 8.0 cm, a width of
seraphim [82]

Answer:

<h3>Density = 0.5 g/cm³</h3>

Explanation:

Density of a substance can be found by using the formula

Density =  \frac{mass}{volume}

From the question

mass = 32g

To find the density we must first find the volume of the block

From the question the block is a cuboid

Volume of cuboid = length × width × height

length = 8 cm

width = 4 cm

height = 2 cm

Volume of block = 8 × 4 × 2 = 64 cm³

Substitute the values into the above formula and solve for the density

That's....

Density =  \frac{32}{64}  \\  =  \frac{1}{2}

We have the final answer as

Density = 0.5 g/cm³

The block will float because it's density is less than the density of water which is

1 g/cm³

Hope this helps you
