They are called carcinogens
The answer would be:
A. Cancel out CO because it appears as a reactant in one intermediate reaction and a product in the other intermediate reaction.
In this question, there are two half-reaction equations. To merge them up, you need to add the reactant with the reactant, then the product with the product. If there is a molecule on both side, you can cancel them. The full reaction would be:
C+ 1/2 O2 + CO + 1/2O2 ==>CO+ CO2 -----> remove CO from both side
C+ O2 ==>CO2
Answer:
27.98g/mol
Explanation:
Using ideal gas law equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
T = temperature (K)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
According to the information given:
V = 2.5L
P = 1.4 atm
T = 282K
n = ?
Using PV = nRT
n = PV/RT
n = 1.4 × 2.5/0.0821 × 282
n = 3.5/23.1522
n = 0.151mol
Using the formula to calculate molar mass of the elemental gas:
mole = mass/molar mass
Molar mass = mass/mole
Molar mass = 4.23g ÷ 0.151mol
Molar mass = 27.98g/mol
I believe the appropriate pair is O and S, Periodic table represents arrangements of elements ordered by their atomic number,physical and chemical properties. Both sulfur and oxygen are in the same group of the periodic table (group 6), they have a valency of 2, This means they have a greater similarity in chemical and physical properties.
quantity of light
Explanation:
The likeliest limiting factor that restricts phytoplankton to approximately the top ten feet of the ocean rather than deeper is the quantity of light available.
- Phytoplankton are plants and they are the major producers in bodies of water.
- The require the process of photosynthesis to manufacture their food.
- During photosynthesis, phytoplankton takes in carbon dioxide and water and uses light to produce food in the process.
- This life activity greatly relies on light.
- The upper part of the ocean usually from 0-200m depth is the photic zone.
- Deeper water is aphotic and receives little to no sunlight.
- The photic zone is the zone where light reaches in water.
- There is abundance of light in the photic zone.
