Hazardous waste, potential reactor accident, and depletes natural waters
Paraphin [41]3 years ago
6 0

Answer:

B. Hazardous waste.

D. Potential reactor accident.

Explanation:

The production of nuclear energy has two biggest drawbacks. First, the risk of accidents in nuclear reactor and the difficulties of storing nuclear waste, which implies the risk of contaminating locations and its surroudings as well.

Caffeine (C8H10N4O2) is a stimulant found in coffees and teas. When dissolved in water, it can accept a proton from a water mole
Olenka [21]

Answer:

See figure 1

Explanation:

If we want to find the acid and the Brønsted-Lowry base, we must remember the definition for each of these molecules:

-) Acid: hydrogen donor

-) Base: hydrogen acceptor

In the <u>caffeine structure,</u> we have several atoms of nitrogen. These nitrogen atoms have the ability to <u>accept</u> hydronium ions (H^+). Therefore the caffeine molecule will be the base since it can accept

If caffeine is the base, the water must be the acid. So, the water in this reaction donated a hydronium ion.

<u>Thus, caffeine is the base and water the acid. (See figure 1)</u>

If your car gets 30.3 mi/gal, how many gallons of gasoline would you use if you drove 506.3 miles? 1 mile = 5280 ft (exactly) In
Salsk061 [2.6K]

Answer: 16.7 gallon

Explanation:

Given: The car can drive 30.3 miles when 1 gallon of gasoline is used.

Distance covered = 506.3 miles

Thus for 30.3 miles, the amount of gasoline used= 1 gallon

For 506.3 miles, the amount of gasoline used=\frac{1}{30.3}\times 506.3=16.7gallon

Thus the amount of gasoline used is 16.7 gallons.

Which of the following is NOT a characteristic of minerals
o-na [289]

Answer:

A. Occur in gaseous and liquid state

Explanation:

The choice that is not a characteristic of minerals is that minerals occur in gaseous and liquid state.

All minerals are solid inorganic compounds.

  • A mineral is an inorganic compound that is formed naturally.
  • They have a definite and specific chemical composition.
  • Minerals are the building blocks of rocks.
  • When minerals aggregates together, they form different rock types.
  • There is no known mineral that is in fluid state.
  • All minerals are solids.
  • Examples are quartz, kaolinite, gypsum e.t.c

What is the charge on an atom after it loses an electron during the formation of a bond?
Sphinxa [80]

I believe the charge is positive as losing an electron suggests that the atom lost a negative charge, leaving it with more positive than negative.

I haven't taken this in a few years very sorry if i'm wrong tho.

Use enthalpies of formation given in appendix c to calculate δh for the reaction br2(g)→2br(g), and use this value to estimate t
Contact [7]

Given reaction represents dissociation of bromine gas to form bromine atoms

Br2(g) ↔ 2Br(g)

The enthalpy of the above reaction is given as:

ΔH = ∑n(products)ΔH^{0}f(products) - ∑n(reactants)ΔH^{0}f(reactants)

where n = number of moles

ΔH^{0}f= enthalpy of formation

ΔH = [2*ΔH(Br(g)) - ΔH(Br2(g))] = 2*111.9 - 30.9 = 192.9 kJ/mol

Thus, enthalpy of dissociation is the bond energy of Br-Br = 192.9 kJ/mol
