Lodine has a density of 4.94 g

Chemistry
1 answer:
atroni [7]3 years ago
6 0

Answer:

41.2 lb/gal

Explanation:

Step 1: Given data

Density of iodine: 4.94 g/mL

Step 2: Convert the mass to grams

We will use the conversion factor 1 lb = 454 g.

4.94 g/mL × (1 lb / 454 g) = 0.0109 lb/mL

Step 3: Convert the volume to gal

We will use the conversion factors 1 gal= 3.785 L and 1 L = 1,000 mL.

0.0109 lb/mL × (1,000 mL/1 L) × (3.785 L/1 gal) = 41.2 lb/gal

Able 1 Cell Type Operating Cell Potential for Commercial Batteries, E (V) Lithium-iodine Zinc-mercury +2.80 +1.35 Table 2 Standa
IrinaK [193]

Answer:

During the initial cell operation, each reaction is thermodynamically favorable, but the larger operating potential of the lithium-iodine cell indicates that its cell reaction is more thermodynamically favorable.  ( B )

During the initial cell operation, the oxidation of iodine is  thermodynamically favorable but the oxidation of mercury is not. ( C )

Explanation:

<u>The major Differences between The Zinc mercury cell and Lithium-iodine cell are :</u>

During the initial cell operation, each reaction is thermodynamically favorable, but the larger operating potential of the lithium-iodine cell indicates that its cell reaction is more thermodynamically favorable.   and

During the initial cell operation, the oxidation of iodine is thermodynamically favorable but the oxidation of mercury is not.

Given the relationship below,

Δ G = -nFE

E = emf of cell ,  G = free energy.

This relationship shows that if E is positive the reaction will be thermodynamically favorable also if E is large it will increase the negativity of free energy  also From the question we can see that with the reduction of mercury the value of E is more positive and this shows that Mercury is thermodynamically unfavorable

Three isotopes of oxygen are oxygen-16 oxygen-17 and oxygen-18. Write the symbol for each, including the atomic number and mass
Karo-lina-s [1.5K]
The symbol of an isotope is:
^A _Z X
A - the mass number
Z - the atomic number
X - the symbol of an element

The symbol of oxygen is O.

The atomic number is the same for all isotopes of one element. For oxygen it's 8, because every atom of oxygen has 8 protons in its nucleus.

The mass number is the number of nucleons (protons + neutrons) in the nucleus of an atom, and it's given in the name of an isotope. Oxygen-16 has the mass number 16, oxygen-17 has the mass number 17, oxygen-18 has the mass number 18.

Oxygen-16: ^{16} _8 O

Oxygen-17: ^{17} _8 O

Oxygen-18: ^{18} _8 O

PLEASE HELP!!!
matrenka [14]

Answer:

d = 0.84 g/cm³

Explanation:

Given data:

Mass of wood = 2.85 g

Volume of water = 20.0 mL

Volume of water + wood = 23.4 mL

Density of wood = ?

Solution:

Volume of wood = (Volume of water + wood ) - Volume of water

Volume of wood = 23.4 mL - 20.0 mL

Volume of wood = 3.4 mL

1 mL = 1 cm³

Density of wood:

d = m/v

d =  2.85 g / 3.4cm³

d = 0.84 g/cm³

How does chemical weathering change rock​
tekilochka [14]

Answer:

Not to be rude but its in there. Hope this helps

Explanation:

Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock.
