The longer it takes sound from a Sonar to return to the ship....................

1 answer:

5 0

The farther away the object is from the ship. For sound to bounce back, it has to travel there and back. Thus, the longer it's out there, the farther it is.

Given the following balanced equation, determine the rate of reaction with respect to [Cl2]. If the rate of Cl2 loss is 4.44 × 1

PolarNik [594]

Answer:

8.88 x 10⁻² M/s

Explanation:

The rate of reaction for:

NO(g) + Cl₂ (g) ⇒ 2NOCl(g)

is rate = -ΔNO/Δt = -ΔCl2/Δt = 1/2 ΔNOCl/Δt

so ΔNOCl/Δt = 2 ΔCl2/Δt = 2 x 4.44 × 10⁻² M/s = 8.88 x 10⁻² M/s

In general given a reaction

aA + bB ⇒ cC + dD

rate = -1/a ΔA/Δt = -1/b ΔB/Δt = 1/c ΔC/Δt = 1/d ΔD/Δt

What volume of a substance will have a mass exactly 750 g if the specific gravity of the substance is 12.2

Ket [755]

The volume of the substance is 61.4 litres.

Explanation:

Specific density is the ratio of density of a substance at a given temperature with the density of reference substance.

Data given:

mass = 750 grams

specific gravity = 12.2

volume=?

The formula to be used:

Specific gravity = $\frac{density of the object}{density of the reference substance}$

suppose the other substance is water so its density is 1g/ml at 4 degrees

Putting the values to the equation:

density of the object = 1 x12.2

density of the substance = 12.2

Now using the formula:

density = $\frac{mass}{volume}$

putting the values in the equation:

volume = $\frac{750}{12.2}$

= 61.4ml is the volume of the substance.
