Answer: 1. HYDROCARBONS? 2. ALKANES?
i'm not exactly AMAZING at this but i did some research and this is what i think it is i'm also not in this grade but i tried.
Answer: It is reactive
Explanation:
Platinum is the least reactive element on the reactive scale.
For example, the platinum doesn't give the reaction with the oxygen that is found in the air, even though if it is heated but platinum does show the reaction with fluorine, chlorine and at red heat. Platinum can be found in a pure form in nature.
Platinum is reactive, it can react with some elements, but it is the least reactive element and also it is called unreactive, it doesn't easily react with elements.
Answer:
B.brief in water vapor, fixed in liquid water, and nonexistent in ice crystals.
Explanation:
Water's States: Gas, Liquid, and Solid
In liquid water, hydrogen bonds are constantly formed and broken as the water molecules slide past each other. The breaking of these bonds is caused by the motion (kinetic energy) of the water molecules due to the heat contained in the system.
Hope It Helps You
wrong it was E. Evaporation of water if your on plato btw
BRAINLY!!!!
Question options:
a) 2.05
b) 0.963
c) 0.955
d) 1.00
Answer:
b) 0.963
Explanation:
H2SO4→ HSO4- + H3O+
HSO4- + H2O ⇌ SO42- + H3O+
Construct ICE table:
HSO4- (aq) + H2O ⇌ SO42- (aq) + H3O+ (aq)
I 0.1 solid & 0 0.1
C -x liquid + x + x
E 0.1 - x are ignored x 0.1 + x
Calculate x
Ka = products/reactants
= ![\frac{[SO42-] [H3O+]}{[HSO4-]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BSO42-%5D%20%5BH3O%2B%5D%7D%7B%5BHSO4-%5D%7D)
0.011 = 
0.011 x (0.1 -x) = o.1x + x^2
0.0011 - 0.011 x - o.1x - x^2 = 0
0.0011 - 0.011 x - x^2 = 0
Use formula to solve for quadratic equation
x = 
/ 2a
a = -1, b = -0.111, c = 0.001
Solve for x
x = ![\sqrt[-(-o.111)]{(-0.111)^2 - 4(-1) (0.0011) }](https://tex.z-dn.net/?f=%5Csqrt%5B-%28-o.111%29%5D%7B%28-0.111%29%5E2%20-%204%28-1%29%20%280.0011%29%20%7D)
/ 2(-1)
x = 0.111 +,- 
/ -2
x = 0.111 +,- 
/ -2
x = 
x = 
, x = 
x = 
, x = 
x = - 0.12015 , x = 0.00915
x cannot be negative, so
x = 0.00915 M
Calculate [H3O+]
[H3O+] = 0.1 M + x
[H3O+] = 0.1 M + 0.00915 M
[H3O+] = 0.10915 M
Clculate pH
pH = - log [ H3O+]
pH = - log [ 0.10915]
pH = 0.963
