Answer:

The answer would be stress

Explanation:

A force that acts on rock to change its shape or volume is stress. Stress adds energy to the rock. The energy is stored in the rock until it changes shape or breaks. Three different kinds of stress can occur in the crust—tension, compression, and shearing.

Find the density of a substance that has a mass of 75 g and a volume of 35 mL. Don't forget your units!

Andrew [12]

Answer:

The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14 $\frac{g}{mL}$

Explanation:

Density is a characteristic property of a substance that relates to the amount of mass it has per unit volume. In other words, density is the property that matter, whether solid, liquid or gas, has to compress into a given space (it measures the amount of mass in a given volume of a substance). It is calculated as the quotient between the mass of a body and the volume it occupies:

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

In this case, you know:

mass= 75 g
volume= 35 mL

Replacing:

$density=\frac{75 g}{35 mL}$

Solving:

$density=2.14\frac{g}{mL}$

The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14 $\frac{g}{mL}$

Calculate the following quantity: volume of 1.403 M copper(II) nitrate that must be diluted with water to prepare 575.2 mL of a

Juliette [100K]

Answer:

328 ml

Explanation:

We have given final volume =575.2 ml=0.575 L

Final concentration = 0.8012 M

We know that moles of copper(II) nitrate = final volume ×final concentration =0.8012×.0575=0.4606 moles

We have to find initial volume

So initial volume $=\frac{moles\ of \ copper(II)\ nitrate}{initial\ concentration}=\frac{0.4606}{1.403}=0.328L=328ml$
