Answer:
FeSO₄ is the Limiting Reactant
Explanation:
3FeSO₄(aq) + 2(NH₄)₃PO₄ (aq) => 3(NH₄)₃PO₄(aq) + Fe₃(PO₄)(s)
315ml(1.25M)FeSO₄ + 405ml(0.95M)(NH₄)₃PO₄
=> 0.315L(1.25M)FeSO₄ + 0.405ml(0.95M)(NH₄)PO₄
=> 0.394mole FeSO₄ + 0.385mole (NH₄)PO₄
Divide by respective coefficient => the smaller value is the Limiting Reactant.
=> 0.394/3 = 0.131 => 0.385/2 = 0.193
Smaller value is associated with FeSO₄
∴the limiting reactant is FeSO₄.
Summery:
1. convert reactant quantities to moles
2. divide reactants by respective coefficients of balanced equation
3. note smaller value after dividing by respective coefficient => Limiting Reactant.
Sodium because according to the atomic size trend of the periodic table. Elements further to the left are bigger while elements tot he right are smaller. This is also do to their charges, Na has a +1 charge meaning it doesn’t pull the electrons as close as the Mg does with its +2 charge.
Correct Answer is Option C i.e. <span>production of wastes needing long-term storage.
Reason:
Most of the nuclear power plant uses nuclear fission reaction for generation of electricity. In a nuclear fission reaction, a radio-active nuclei (high atomic mass) is bombarded with fast moving projectile. This results in nuclear disintegration. The mass defect between product and reactant results in generation of energy. The daughter element generated during this event, may also be radio-active in nature. These materials have extremely high half-life. Hence, this waste product needs to be stored safely for long-time so as to minimize the risk of nuclear contamination. </span>
Answer:
Explanation:
a) The pH can be define as the measurement of the hydrogen or hydroxide ion concentration in a solution. The pH for blood is 7.4. In severe acidosis condition the pH of blood is 7.35 or lower.
b) Severe acidosis is a condition which is caused due to the overproduction of acid and building up of acid in the blood. This occurs due to the excessive loss of bicarbonate from the blood or buildup of carbon dioxide in the blood. This leads to poor functioning of the lungs and depressed breathing.
The severe acidosis is critical condition because because it can adversely affect the cell membranes, muscle contraction, and function of the kidneys and neural activity of the body.
Here we have to judge the statement about the hydrogen bond is true or false for water molecule.
The both the statement about hydrogen bonding in water is true i.e. The water molecule can act as hydrogen-bond donor and acceptor.
The hydrogen bond is a weak interaction between a hydrogen atom and an electronegative atom.
In water (H₂O) there remains hydrogen atom (H) and also the electronegative atom oxygen (O). The donor property and acceptor property to produce hydrogen bond in water is shown in figure.
The donor and acceptor property of water is shown in the figure.
