is it hard or easy because im not that good at math .i am ok but not the best because sometimes i do mistake and is there any factoring or graphing???? i dont want to get kicked out i love my school?-
Topic: Thermodynamics
Is it possible for a system to do work ( or get work done on it ) without changing its volume? i.e. isochoric process ...
Please give explanation also. Thanks!-work done= + PRES
Thermodyanmics:::-
The heat evolved in neutralisation of NaOH by HCL is x joules and that of NaOH by CH3COOH is y joules. Which of the follows is true?
a] x=y
b] x>y
c] x
d] Relations cannot be pre
If anyone knows how to solve them, then, Plz help me out...!
1.Calculate the molarity of the following solutions:-
(a) 4g of caustic soda is dissolved in 200mL of the solution.
(b) 5.3g of anhydrous
Lets say i bought iodine in the mail and it was irradiated so the iodine is now irradiated and can hurt the thyroid instead of helping. How can I tell if the iodine is radioactive? Are there any simpl
help please with solution-Let x and y be the numbers youre looking for.
Given: xy = 1014
Given: x + y = 65
Rearrange that last one:
y = 65 - x
Substitute this value for y into the first given equation
If false, then rewrite your statement so that it becomes true.-False. The correct sentence will be when the dry ice changes to carbon dioxide the molecules separates out leading to the expansion of vo
A gas 2.48 L at 85.0 C and 725 torr. What is the volume will it occupy at STP ?
Ok well first combined law is P1xV1/ T1 = P2 xV2 /T2
Ok first I have to convert temp from C 273 + 85.0 = 358 K
Then
I worked that out myself by showing products. How do I balance this? Or how do I begin?-Ca(HCO3)2 + H2SO4 ---> CaSO4 + H2O + CO2
1Ca.......1Ca
4H.........2H
2C.........1C
10O.......7O
1S.........1S
A question asks me: Assuming that Carbon has only one type of isotope (13C) estimate the mass and number of moles of 13C in 300g of carbon?
How am I supposed to figure this out? Please show all work
1) A crystal is most likely to have a low melting point, if it
a) is a macro molecule
b) is a crystal lattice
c) has delocalisedvalence electrons
d) has weak van der Waals forces
2)Which two elements
is it a neutral OH?-Nope its not a dumb question. In neutral reaction, its said to be the combination of hydrogen ion and a hydroxide ion to form salt and water.so you have
H+ + OH- =H2O(WATER).-Nope,
The bombardment of 198Hg with neutrons produces 198Au.
How would i write a complete reaction for this process?
What would the other product of the bombardment reaction?-198Hg + n ---> 198Au + n + e
