False. Because though some part of the Earth does have ice, ice is far different from land. As well as I dont think there is even such a thing as an "ice core", by means of other planets. <span />
Answer:
(a) 7.0 (b) 7.30 (c) 8.42
Explanation:
(a) HBr is a strong acid and NaOH is also a very strong base, hence, the solution will be neutral give a pH of 7.0
(b) HClO3
ClO2- + H20 <=> HClO2- + OH-
ClO2- = 0.1*0.08/0.18 = 0.044M
Kb=Kw/Ka=1.0 x 10^-14/1.1 x 10^-2=9.09x10^-13
[OH-] = 2.0 x 10^-7M
p[OH] = 6.7
pH = 7.3
(c) C6H5COOH
C6H5COO- + H20 <=> C6H5COOH + OH-
[C6H5COO-] = 0.1 * 0.80/0.180 = 0.44
Kb=Kw/Ka=1.0 x 10^-14/6.3 x 10-²=1.59x10^-10
[OH] = 1.59x10-10/0.44 = 2.69x10-6
pOH = 5.58
pH = 8.42
Answer:
Data collection/ analysis
I think. Its part of the scientific method
Answer:
Double, acid, base, water, salt.
Explanation:
The general reaction of a neutralization is:
X(OH) + YH → H₂O + XY
If you see, the reaction is a <em>double replacement reaction </em>because the cation and the anion of the two reactants switch places, forming two new compounds or products.
Always, the reaction starts with an <em>acid </em>and a <em>base </em>and will produce <em>water </em>and a <em>salt. </em>
I hope it helps!
