As the commercial jetliner is flying at 253 meters per second.

there are 60 seconds in 1 min, and 60 minutes in 1 hr, and so there are 3600 seconds in a hour

as the jetliner is flying 253 meters per second, you will multiply 253 x 3600.

You will then get 910800 meters in 6 hrs.

1 mile = 1609.34 meters, and so 910800 meters = 565.944882 miles.

rounding 565.944882, you will get 565.945, or 566 miles as your answer

hope this helps :D

The study of the structures of deep-sea vents and of the life around them represents an intersection of which two fields of scie

Bond [772]

Answer: Option (B)

Explanation:

Geology is the study of all the earth dynamic processes, about the various types of rocks, its physical and chemical properties, about the ancient lives, and covers many more topics.

Whereas, Oceanography refers to the study of the marine ecosystem, its biological properties as well as its physical and chemical properties.

This two fields of science namely geology and oceanography is required to study about the deep sea vent structures as well as the life forms that exists around them.

Deep sea vents are the cracks and openings found underwater from which the hot water comes out in association with numerous gases.

Thus, the correct answer is option (B).

A 3.20-mol sample of gas occupies a volume of 350. mL at 300.0 K. Determine the

nalin [4]

Answer:

$P \approx 225atm$

Explanation:

From the question we are told that:

Moles of sample n=3.20_mol

Volume V=350mL

Temperature T=300k

Generally the equation for ideal gas is mathematically given by

$PV=nRT$

$P=\frac{nRT}{V}$

$P=\frac{3.20*0.08206*300}{350*10^{-3}}$

$P=225.079atm$

$P \approx 225atm$

A fixed quantity of gas fills a volume of 10.6 liters at 638 torr and 83 C. Find the volume it will occupy if the pressure is 10

sukhopar [10]

According to this formula:
(P1V1) / T1 = (P2V2) / T2

convert T from C° to Kelvin:
T1 = 83 + 273 = 356 K
T2= 96 + 273 = 369 K

convert P from torr to atm:
1 torr = 0.00131578947 atm
p1 = 0.839474 atm
P2 = 1.415789 atm
By substitution in the previous formula:
(0.839474 x 10.6 ) / (356) = ( 1.415789 x V2 ) / 369
So:
V2 = 6.5 L

In the following net ionic equation, identify each reactant as either a Bronsted-Lowry acid or a Bronsted-Lowry base. HCN(aq) H2

vfiekz [6]

Answer:

Explanation:

The definition of acids and bases by Arrhenius Theory was modified and extended by Bronsted-Lowry.

Bronsted-Lowry defined acid as a molecule or ion which donates a proton while a base is a molecule or ions that accepts the proton. This definition can be extended to include acid -base titrations in non-aqueous solutions.

In this theory, the reaction of an acid with a base constitutes a transfer of a proton from the acid to the base.

From the given information:

$\mathsf{HCN _{(aq)} + H_2O_{(l)} \to CN^{-}_{(aq)} + H_3O_{(aq)}}$

From above:

We will see that HCN releases an H⁺ ion, thus it is a Bronsted-Lowry acid

$H_2O$ accepts the H⁺ ion ,thus it is a Bronsted-Lowry base.

The formula of the reactant that acts as a proton donor is HCN

The formula of the reactant that acts as a proton acceptor is H2O
