Answer: Photosynthesis
Explanation: Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
the answer is a - they are slow and gradual processes.
Answer: P=1.63atm
Explanation:
Stp means standard temperature and pressure
Standard temperature =273k
Standard pressure =1atm
Using the formula
P1V1/T1=P2V2/T2
P1= 1atm
V1=5.23L
T1=273k
P2=?
V2=3.45L
T2=293k
Substitute the values
1×5.23/273=p2×3.45/293
Cross multiply
293×1×5.23=p2×3.45×273
1532.39=941.85p2
P2=1532.39/941.85
P2=1.627
P2=1.63atm
Answer:
Have similar chemical properties
Explanation:
- The periodic table of elements is made up of groups or families and periods.
- Elements in the same group or chemical family share similar chemical properties.
- For example, elements in group II have similar chemical properties. They include Calcium and magnesium.
- A similar chemical property of group II elements is that they react with water to form metal hydroxide and hydrogen gas.
Acids are ionic compounds with hydrogen at the front. Bases are ionic compounds with hydroxide at three back(bronsted definition)
A conjugate acid is a base that has gained a proton(hydrogen ion) and a conjugate base is formed when an acid has given up its proton.
