Answer: 34.4 g
Explanation:
As is in excess, is the limiting reagent and thus it will limit the formation of products.
According to stoichiometry:
2 moles of hydrogen produce = 1 mole of
2.5 moles of hydrogen produce = of
Mass of
But as % yield is 86%, mass of produded is
Thus 34.4 g of is produced.
Answer:
Photosynthetic bacteria must take in <u>Carbon Dioxide</u> to live, and they release <u>Oxygen </u> . Animals must take <u>Oxygen </u> to live, and they release <u>Carbon Dioxide.</u>
Explanation:
Photosynthesis:
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
Carbon dioxide + water + energy → glucose + oxygen
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Chemical equation:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
Photosynthetic bacteria perform same function as plants. These bacteria contain light harvesting pigments absorb carbon dioxide and release oxygen.
While animals take oxygen and release carbon dioxide to live. This respiration process is opposite to the photosynthesis.
Glucose + oxygen → carbon dioxide + water + 38ATP
Nitrogen dioxide is a toxic gas and therefore it is important for a person handling the gas not to inhale these fumes. Also one needs to protect their eyes while working with the gas.
Therefore following safety precautions should be taken to protect against the hazards of nitrogen dioxide
1) One should wear safety goggles to prevent the fumes from entering into the eyes.
2) Protective mask is needed to prevent the inhalation of the fumes.
Concentrated acid can cause burns if it comes in contact with the skin. It may damage the cloths as well. often times concentrated acids emit toxic fumes. Therefore following safety precautions are needed while handling concentrated acid.
1) One should wear safety gloves to prevent the acid from coming in contact with the skin
2) One should wear protective masks to protect themselves from the fumes.
3) One should also wear protective apron to prevent the damage to the cloths.
You did not provide the statement, however, the most accurate things about atoms is that everything is made out of them in the entire universe, and they consist of protons, electrons, and neutrons. They create all substances in existence.
Answer:
3.37 m
Explanation:
<u>Number of moles of solute present in 1 kg of solvent is termed as molality</u>
It is represented by 'm'.
Thus,
Given that:
The mass of LiCl = 15.0 g
Molar mass of LiCl = 42.394 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of the solvent = 105 g
Also, 1 g = 0.001 g
So,
Mass of water (solvent) = 0.105 kg
Molality is:
<u>Molality = 3.37 m</u>
