D : chloroplasts , it’s a plant cell
The answer is (3)amine. The aldehyde structure is -CHO. The alcohol structure is -OH. The amine structure is -NH2. And the ether structure is R-O-R'. The "R" means other function groups.
Sample Response:<span> The brain, through the nervous system, sends signals to the muscular system, causing the muscles to move rapidly. This rapid motion produces heat in the body and is observed as shivering. The brain also sends signals to the muscles right beneath the skin. These muscles shorten and tighten, causing the hairs on the skin to stand up. When the hairs stand up, heat is kept in the air trapped within the hairs, which keeps the body warm.</span>
Answer:
0.5 M
Explanation:
First, let us look at the balanced equation of the reaction.
The solute formed is .
Recall that: mole = molarity x volume
Hence,
50 ml, 1.00 M H2SO4 = 0.05 x 1 = 0.05 mole
50 ml, 2.0 M KOH = 0.05 x 2 = 0.1 mole
From the equation
<em>1 mole of H2SO4 reacts with 2 moles of KOH to give 1 mole of K2SO4.</em>
Hence,
<em>0.05 mole H2SO4 reacting with 0.1 mole KOH will give 0.05 mole </em><em>.</em>
Also recall that: concentration = mole/volume
Total volume of resulting solution = 50 ml + 50 ml = 100 ml or 0.1 liter
Concentration of = mole of /volume of resulting solution
= 0.05/0.1 = 0.5 M
The concentration of the resulting solute = 0.5 M
