Answer:535.5g
Explanation:
1) find the volume of the object
=L*W*H
=1.8*3.5*10.0
=63cm^3
2) the original formula is solving for the dencity which we have so...
D=M/V
M=D*V
M=8.5(63)
M=535.5g
Answer:
1) accepts a proton
Explanation:
CO₃⁻² is a base here because it is accepting a proton ( H⁺) through coordinate bonding by donating a pair of electron .
So option (1) is correct .
2) 1
3) 1
4) 2
5) 3 or 2, I’m not sure
6) 1
7) 2
8) 1
9) 4
10) 2
11) 3
12) 1
I hope this helps, good luck.
Answer:
The emission spectrum is formed when the electrons of a particular atom absorb energy and are excited (in this case by heating), reaching higher energy levels.
You can see it for example with an experiment where we light alcohol mixed with banana chips (it has potassium). The burning alcohol emits heat that makes potassium atoms excite and these in turn emit something red, orange light. If we add for example boric acid you see a green light.
Explanation:
A solution is a homogeneous mixture consisting of a solute dissolved into a solvent . The solute is the substance that is being dissolved, while the solvent is the dissolving medium. Solutions can be formed with many different types and forms of solutes and solvents.
