Answer:
28.38 ml of H202
Explanation:
<u><em>Given data:</em></u>
the concentration of H2O2 = 3.0 % v/v (3ml / 100 ml of solution of H2O2
the volume of the bottle : 946 ml
<em><u>Formula: </u></em>
Percent by volume: volume of solute/volume of solution×100%
<em><u>Solution:</u></em>
= (3.0 mL/ 100 ml) × 946 mL
= 0.03 x 946 ml
= 28.38ml of H202
Answer:
Explanation:
The collision theory explains why reactions occur between atoms, ions, and molecules. With the increase in temperature, there is an increase in the number of collisions. Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate.
Answer : The correct option is, (C) Both the atomic mass and the atomic number increase from left to right.
Explanation :
The general trend of atomic number and atomic mass in the periodic table is,
Both atomic number and atomic mass increase from left to right and decreases from right to left in the periodic table due to the addition of the number of neutrons and the number of protons in the nucleus.
Hence, the correct option is, (C) Both the atomic mass and the atomic number increase from left to right.
