Answer:
Sorry i really dont know goodluck
Explanation:
"NUCLEAR POWER" produces "no air pollution".
Option: D
<u>Explanation</u>:
As nuclear power does not emit any hazardous gas or smoke thus it produces no air pollution. But disposing of the waste is still a big issue in the case of nuclear power for which usually underground disposal in appropriate container method is opted but it's too have many disadvantages. Threat of an accident and the expenses of constructing nuclear reactors are really high so other three options are disadvantages of nuclear power.
Answer:
= 7392 kg solution
Explanation:
detailed solving is given in the attached document.
Answer:
81°C.
Explanation:
To solve this problem, we can use the relation:
<em>Q = m.c.ΔT,</em>
where, Q is the amount of heat released from water (Q = - 1200 J).
m is the mass of the water (m = 20.0 g).
c is the specific heat capacity of water (c of water = 4.186 J/g.°C).
ΔT is the difference between the initial and final temperature (ΔT = final T - initial T = final T - 95.0°C).
∵ Q = m.c.ΔT
∴ (- 1200 J) = (20.0 g)(4.186 J/g.°C)(final T - 95.0°C ).
(- 1200 J) = 83.72 final T - 7953.
∴ final T = (- 1200 J + 7953)/83.72 = 80.67°C ≅ 81.0°C.
<em>So, the right choice is: 81°C.</em>
The generic reaction a + b = c, represents a synthesis or combination reaction, which is a kind of chemical reaction.
<h3>What is a synthesis reaction?</h3>
A synthesis, or combination reaction, is a kind of reaction in which two substances combine to form a bigger molecule.
The generic reaction is:
a + b = c
Some common synthesis reactions are:
- Two elements combine to form a compound.
Fe + S = FeS
- One element and one compound combine to form a compound.
O₂ + 2 SO₂ = 2 SO₃
- Two compounds combine to form another compound.
CaO + CO₂ = CaCO₃
In all the examples above, we can verify that the substances (elements or compounds) combine with each other to form another substance (product).
The generic reaction a + b = c, represents a synthesis or combination reaction, which is a kind of chemical reaction.
