A woman and a male have sex. The man ejaculates sperm into the females uterus. If one attaches to the woman’s eggs, it will fertilize the egg and impregnate that woman. If more than one sperm attached to an egg that’s how twins are made
Answer:
One mol is added to a solution of acids
One mol is added to a solution of base.
Explanation:
Titration is a process of adding one concentration of solution to another solution until the reaction neutralizes. In acid base titration the concentrated acid solution is titrated with concentrated base solution. Ph indicator is used to monitor the reaction. When reaction neutralizes it changes its color to pink indication that the reaction is completed.
To find the concentration, use the following formula--> molarity= moles/ liters
liters= 650.0 mL= 0.6500 Liters
we need to convert the grams to moles using the molar mass of NH3
molar mass of NH3 = 14.0 + (3 x 1.01)= 17.03 g/ mol
25.0 g NH3 ( 1 mol/ 17.03 grams)= 1.47 mol
concentration= 1.47 mol/ 0.6500 Liters= 2.26 M
Answer:
B
Explanation:
Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface.
