Answer is: <span>concentration of fluoride in the water in parts-per-million is 1 ppm.
</span>Parts-per-million (10⁻⁶) is<span> present at one-millionth of a </span>gram per gram of sample solution, f<span>or example mg/kg.
</span>m(fluoride) = 500 g · 1000 mg/g = 500000 mg.
m(water) = d(water) · V(water).
m(water) = 1 kg/L · 500000 L.
m(water) = 500000 kg.
arts-per-million = 500000 mg ÷ 500000 kg = 1 mg/kg = 1 ppm.

How would you describe the sequence of reactions in a hydrogen bomb
VLD [36.1K]

A hydrogen bomb is a  nuclear bomb, like an atomic bomb, where the explosive energy comes from as nuclear reaction.  

A hydrogen bomb is about fusion — fusing atomic nuclei together to combine into bigger ones.

A hydrogen bomb, or a thermonuclear bomb, contains a fission weapon within it but there is a two-stage reaction process.

The U.S. used two atomic bombs in World War II against Japan, Then, in 1952 and 1954

In particular, monitors will be looking for isotopes of a gas called xenon, which is typically present in H-bomb reactions.

What is the volume of a salt crystal measuring 1.64 x 10^-2m by 1.5 x 10^-2m by 4.8 x 10^-3
lubasha [3.4K]

Answer:

V = 1.2 × 10⁻⁶ m³

Explanation:

Volume is equal to length × width × height, since we are given these measurements in the question we can simply plug our numbers into the formula.

V = l × w × h

V = 1.64 x 10⁻² × 1.5 x 10⁻² × 4.8 x 10⁻³

V = 1.2 × 10⁻⁶ m³

Solution A has a pH of 3 and solution Z has
igor_vitrenko [27]
PH of a solution is -ln[H3O+] so,in case of A pH=3 or,-log[H3O+]=3 or,[H3O+]=10^-3 in case of B pH=6 pr,-log[H3O+]=6 or, [H3O+]=10^-6 so,hydronium ion concentration in solution A /the hydronium ion concentration in solution Z =10^-3/10^-6 =1000 2) Ca(OH)2+2 HNO3=Ca(NO3)2+2 H2O so the answer is 2.
