H2o only has one oxygen molecule. so +o2 should just be +o
The two compounds present
in unpolluted air are carbon dioxide and water. You may think that carbn
dioxide is a greenhouse gas, yes it is and at the same time not. There animals
in the earth that produces carbon dioxide into the atmosphere, the carbon
dioxide too, is also need for plan respiration.
Answer:
is the notion of an atom 'X', if the mass number is A and the atomic number is Z
Explanation:
The symbol of the element is "X"
The notion comprises of symbol of element "X" in the center.
On the upper left side of the symbol mass number "A" is kept and on the lower left side of the symbol, atomic number "Z" is kept.
Thus, notion will be
Answer:
C. 1.3 mol
Explanation:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is universal gas constant,
and T is absolute temperature.
Given:
P = 121.59 kPa
V = 31 L
T = 360 K
R = 8.3145 L kPa / mol / K
Find: n
n = PV / (RT)
n = (121.59 kPa × 31 L) / (8.3145 L kPa / mol / K × 360 K)
n = (3769.29 L kPa) / (2993.22 L kPa / mol)
n = 1.26 mol
Round to two significant figures, there are 1.3 moles of gas.
Answer:
A beach forms when waves store sand and rock along the shoreline. A few sea shores are comprised of rocks and stones. After some time, they are moved around smooth by the waves.
Explanation:
A beach is a geologic arrangement that is situated along a huge waterway, including lakes, streams, and seas. Sea shores are described by the presence of small bits of natural silt. The dregs might be made out of sand, rock, shell, green growth, or stones. Normal sea shores may take a large number of years to advance, a cycle that is the consequence of continually moving water that disintegrates the land situated around its edge. Basically, rocks or coral reefs situated off the shore are worn out by moving waves. Moreover, streams and rainwaters may dissolve rocks found further inland. These dregs are stored along the coastline, framing a sea shore.
