Volume= mass divided by density
V= m/d
55/3.23
= 17.03
Answer:
Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. If temperatures drop low enough, the water will freeze. ... This specific process (the freeze-thaw cycle) is called frost weathering or cryofracturing.
Answer:
a. The temperature should be increased.
b. 342.86K
Explanation:
Using Charles law equation as follows:
V1/T1 = V2/T2
Where;
V1 = initial volume (mL)
V2 = final volume (mL)
T1 = initial temperature (K)
T2 = final temperature (K)
According to this question, the following information were given:
V1 = 210mL
V2 = 360mL
T1 = -73°C (-73 + 273 = 200K)
T2 = ?
Using V1/T1 = V2/T2
210/200 = 360/T2
Cross multiply
200 × 360 = 210 × T2
72000 = 210T2
T2 = 72000/210
T2 (new temperature) = 342.86K
Answer:
Do you have the video so I can watch it?
Explanation:
Answer:
The answer to your question is Ke = 1.4751
Explanation:
Data
bromine = 0.6 mol
iodine = 1.6 mol
volume = 1 L
Ke = ?
Iodine monobromide concentration = 1.190 M
Process
1.- Write the balanced chemical equation
Br₂ + I₂ ⇒ 2IBr
2.- Write the formula for Ke
Ke = [IBr]²/[Br₂][I₂]
3.- Substitution
Ke = [1.19]² / [0.6][1.6]
4.- Simplification
Ke = 1.4161 / 0.96
5.- Result
Ke = 1.4751
