Rubidium would exhibit the greatest shielding [ effect. ]
Equation is:
Ca(NO3)2 + Na3PO4 —> NaNO3 + Ca3(PO4)2
Balance it out
3Ca(NO3)2 + 2Na3PO4 —> 6NaNO3 + Ca3(PO4)2
You have 96.1g of Calcium Nitrate
Moles = Mass/Molar Mass
Molar mass of Calcium Nitrate is 164.088 g/mol
96.1g / 164.088 g/mol =0.586 moles
Mole ratio is 3:1
Therefore 0.586/3 moles of calcium phosphate
Moles x molar mass = mass
0.586/3 x 310.18 g/mol = 60.6~g roughly as theoretical yield
Yes I think yesi,m not really suer
Answer:
<h2>1. precede emotional experience</h2><h2>2. occur at the same time</h2>
Explanation:
William James and Carl Lange gave a theory about a type of emotion is called a James-Lange theory. According to this theory, physiological arousal creates an emotional experience. According to this theory, physiological changes are the primary condition while emotion is felt when brain interacts with the information obtained from the body.
According to the Cannon-Bard theory, the emotional feeling occurs when the dorsal thalamus is stimulated. In this theory, physiological changes and emotional experiences take place at the same time.
P = 600 mmHg
V = 2.2 L
T = 85°C
R = 0.08206 L atm / mol K
n = ?
I would start by converting the P from mmHg to atm, since our gas constant R uses atm.
600 mmHg • 1 atm / 760 mmHg = 0.789 atm = P
Then I would convert T from Celsius to Kelvin, since our gas constant R uses Kelvin.
85 + 273 = 358 K
Now you can solve PV = nRT for n, giving you:
n = PV/RT
n = (0.789 atm)(2.2 L) / (0.08206 L atm / mol K)(358 K) = 0.059 moles of gas
