Tatiana [17]3 years ago
6 0

Answer:

The mass of 4.5 moles of Cu(NO3)2 is 843.55g

Explanation:

Mass = moles x Molar mass

Mass = 4.50(187.55)

         = 843.97g

Your solution has a volume of 36 ml and a mass of 970 g. what is the density of your solution
LenaWriter [7]

Answer:

The answer is

<h2>26.94 g/mL</h2>

Explanation:

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

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

From the question

mass = 970 g

volume = 36 mL

The density of the object is

density =  \frac{970}{36}  \\ 26.944444...

We have the final answer as

<h3>26.94 g/mL</h3>

Hope this helps you

Boiling water is a physical change, because it is changing state of matter, there is a controllable temperature change, and you can change it back.

Frying the egg white is a chemical change, because there is a change of matter, controllable temperature change, but you CAN'T change it back.

In an ecosystem, what do organisms and populations with similar needs compete<br>over?​
hram777 [196]

Answer:

In any ecosystem, organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction. Growth of organisms and population increases are limited by access to resources.

If fluorine 20 undergoes beta decay , what will it become ?
e-lub [12.9K]
Fluorine 20 (F - Atomic number 9 and atomic mass 20). Firstly we need to know what is beta decay. Beta decay occurs when one neutron changes into a proton and an electron therefore the atomic mass will remain the same as even though we loose a neutron it is replaced by a proton, the atomic number is always raised by 1 when one beta decay occurs. The produced electron is shot out of the nucleus at an incredible speed. This speedy electron we call a beta particle.

Ok now the reaction.

 20       20        0
F  -> Ne    +     e
 9         10       -1

Remember the atomic number determines the nature of the element ( i.e what elemnt it is).
Hope this helps :).
