Explanation:
Gas particles are spread farther apart and move faster than solids or liquids. ... The average speeds and kinetic energies of gas particles increase with an increase in temperature and decrease with a decrease in temperature.
Explanation:
Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.
Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions.
When oxidizing agent-A get reduced it changes green to colorless.
When oxidizing agent-B get reduced it changes yellow to colorless.
When oxidizing agent-C get reduced it changes red to colorless.
1) When we added solution C that oxidizing agent-C in solution containing 
ions changes from red to yellow:
So, in this C is oxidizing ion into B which yellow in color.
C is reduced and ions is oxidized.
Here, are oxidized by C which means that C a better oxidizing agent than B.
2) When a solution of C is mixed with one containing A- ions, the color remains red.
no reaction
As we had observed that no color change was seen on adding substance C to the solution with 
ions which indicates that C was unable to oxidize ions. Hence, not a better oxidizing agent than A
Answer:
0.56 mL
Explanation:
Volume = mass ÷ density
Volume = 1.5 ÷ 2.7 g/mL
Volume = 0.5555555556 = 0.56 mL
The volume of the aluminum block is 0.56 mL.
Hope this helps. :)
Answer:
Answer below.
Explanation:
An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
Answer:
Explanation:
Total mass of substance = 7.22 + 2.53 + 5.25 g
= 15 g
percentage of nickel = 7.22 x 100 / 15
= 48.13
= 48.1 %
percentage of phosphorus = 2.53 x 100 / 15
= 16.87%
= 16.9%
percentage of oxygen = 5.25 x 100 / 15
= 35 %
