Social interactions help lower the risk of Alzheimer diseases by stimulating the brain. Many studies show that if you use your brain more you have a lower chance of getting Alzheimer's.
Answer: 10.2 grams
Explanation:
The balanced chemical reaction is :

According to the ideal gas equation:

P = Pressure of the gas = 740 torr = 0.97 atm (760torr=1atm)
V= Volume of the gas = 12.0 L
T= Temperature of the gas = 19°C = 292 K 
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas


According to stoichiometry:
2 moles of hydrogen are generated by = 1 mole of 
Thus 0.48 moles of hydrogen are generated by =
moles of 
Mass of 
Thus 10.2 grams of
are needed to generate 12.0 L of hydrogen gas if the pressure of hydrogen is 740. torr at 19°C
Answer:
See the answer and explanation below , please.
Explanation:
A conjugate base is defined as that formed after an acid donates its proton.
For each article, a continuation of the conjugate bases (highlighted in bold), for dissociation in water:
a) HF + H20 --> F- + H30+
b) H20+ H20 --> OH- + H30+
C)H2PO3- + H20--> HPO3 2- + H30+
d) HSO4- + H20 --> SO4 2- + H30+
E) HCL02 + H20 --> CLO02 - + H30+
Answer:
The Bohr model of the atom explains the reactivity of all atoms.
