Answer:
A.
Explanation:
Power is measured in Watts, and can we calculated by taking the work done in joules / the time in seconds. Thus, 1 Watt is 1 joule per 1 second (1 Watt = 1J/s)
Answer:
Collagen is a "fibrous proteins" present in the extracellular matrix.
Explanation:
Protein are made up of hundreds or thousands of smaller units called amino acids and is made of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur and is found in many foods. Proteins are organic molecules found in living organisms.
There are three types of proteins; fibrous, globular, and membrane.
Collagen which is a fibrous proteins, form muscle fiber, tendons, connective tissue and bone.
Collagen are naturally occurring proteins that consist of single molecules made up of amino-acids, which are in turn built of carbon, oxygen and hydrogen. It is mostly found in fibrous tissues such as tendons, ligaments, and skin.
The synthesis of collagen occurs in two stages: intracellular and extracellular.
Collagen is an abundant connective tissues such as cartilage, tendons, bones, and ligaments. Collagen is a contributing factor to variation in meat tenderness and texture.
Evaporation from the rivers, seas and so on,
and transpiration from the plants.
Answer:
223 L
Explanation:
Step 1: Write the balanced equation.
2 LiOH + CO₂ = Li₂CO₃ + H₂O
Step 2: Calculate the moles corresponding to 440 g of LiOH
The molar mass of LiOH is 23.95 g/mol.
440 g × (1 mol/23.95 g) = 18.4 mol
Step 3: Calculate the moles of CO₂ that react with 18.4 moles of LiOH
The molar ratio of LiOH to CO₂ is 2:1. The reacting moles of CO₂ are 1/2 × 18.4 mol = 9.20 mol.
Step 4: Convert 20°C to Kelvin
K = °C + 273.15 = 20 + 273.15 = 293 K
Step 5: Convert 753 torr to atm
753 torr × (1 atm/760 torr) = 0.991 atm
Step 6: Calculate the volume of CO₂
We will use the ideal gas equation.
P × V = n × R × T
V = n × R × T / P
V = 9.20 mol × (0.0821 atm.L/mol.K) × 293 K / 0.991 atm
V = 223 L
