Answer:
what is the net ionic equation
H2SO4(aq) + Cal2(aq) → CaSO4(s) + 2Hl(aq)?
A. H++ SO42- + Ca2+ + 21 → CaSO4 + H+ +1-
B. 2H+ + S042- + Ca2+ + 21° → Ca2+ + SO42- + 2H+ + 21
C. S042- + Ca2+ → CaSO4,
D. 2H+ + SO42- + Ca2+ + 2I- → CaSO4 + 2H+ + 2I-
cancel the spectator ion that is the ions which does not take place in the reaction
for this case is 2 H^+ and 2 i^-
Hello There! ^_^
Your question: What is the pressure of a fixed volume of hydrogen gas at 38.8°C if it has a pressure of 1.36 atm at 15.0°C..?
Your answer: P1/ T1= P2/ T2
Change C to Kelvin
273+ C= K
38.3+ 273= 311K
15.0+ 273= 288K
2.38/ 288= P2/ 311.3
740.894= 288 (P2)
P2= 2.57 atm.
Thus, you got you answer!
Hope this helps!

S<span>plit people in two groups of Casodex resistant treatment men (double -blind cross-over study) </span>
<span>50% get Casodex 50 mg ( BICALUTAMIDE 50 MG ) 1 tablet daily + 1 placebo tablet </span>
<span>Casodex is an anti testosterone agent. </span>
<span>50% get Casodex 50 mg 1 tablet daily + 1 Tamoxifen 20 mg tablet </span>
<span>Tamoxifen is an estrogen receptor inhibitor </span>
<span>Compare the results of tumor growth over 1 year's time then reverse the groups without the physician or the patient knowing if they are receiving tamoxifen or the placebo tamxoifen then compare tumor growth results again.</span>
Answer:
frequency = velocity of light /wavelength
wavelength = velocity / frequency
=3 x10^8 / 5.9 x 10^11
=0.508 x 10^-3.
