Answer:

C. the correct Technology cannot support this mission

Explanation:

There is not enough technology to make it possible to plan a mission safely for this distance. What can be done to study this planet is to visualize it with super powerful telescopes and to use simulations to analyze and identify the dynamics of the axis of rotation of the planet. These dynamics determine how much a planet tilts on its axis and how that angle of inclination evolves over time.

What chemical warfare agent (cwa) primarily attacks the airway and lungs, causing irritation of the entire airway from the nose

VLD [36.1K]

The chemical warfareagent that attacks primarily the airway and the lungs would be a choking agent. It would cause irritation of the whole respiratory system resulting to dry-land drowning. Examples are chlorine gas, phosgene, acrolein and chloropicrin.

The first-order reaction, so2cl2 → so2 + cl2, has a rate constant equal to 2.20 × 10-5 s-1 at 593 k. what percentage of the init

Svetradugi [14.3K]

For the 1st order reactions,rate constant (k) is mathematically expressed as

k = $\frac{2.303}{t}log \frac{Co}{Ct}$
where, t = time
Co = initial conc. of reactant
Ct = conc. of reactant after time 't'

Given: k = 2.20 × 10^-5 s-1, t = 2 hours = 7200 s

Therefore, we have
2.20 × 10^-5 = $\frac{2.303}{7200}log \frac{100}{Ct}$
∴ $log\frac{100}{Ct}$ = 0.06877
∴, $\frac{100}{Ct}$ = 1.1716
∴, Ct = 85.35%

Thus, 85.35 % of the initial amount of SO2Cl2 will remain after 2.00 hours.

What is the hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4.

Maksim231197 [3]

The hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4 is 2.7.

pH= -log[H+] - (i)

10^-3=H2So4

H+= 2×10-3

here ,

h2so4 ——— 2[H+] + so4^2-

thus [H+]= 2*10^(-3) because hydrogen ion has two moles

pH= -log[H+]

pH= -log(2×10^-3)

pH= 3-log2

pH= 3-log2pH= 2.7

The pH is 2.7

PH is the degree of alkalinity and acidicity in a solution.

Therefore, The hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4 is 2.7
