Its kinda hard to anwser this question but i hope this helps Velocity is a vector quantity. It has a (positive) magnitude and a direction. For one-dimensional motion, this can be represented as a one-dimensional vector, which looks just like a positive or negative number. A negative number indicates motion in the direction of the negative axis.

Answer:

D. Velocity in one dimension may be positive or negative, while speed always has a positive value.

Explanation:

<em>Velocity</em> is the rate at which an object changes position in a specific direction. It has both <em>magnitude and direction</em>.

For example, travelling southeast at 90 km/h is a velocity. It gives both speed and direction.

Velocity is a vector. If your velocity is 90 km/h in one direction, it is -90 km/h in the opposite direction.

Travelling at 90 km/h is a speed. It does not give direction, so it is always positive.

A. <em>Wrong</em>. Velocity has both positive values.

B. <em>Wrong</em>. Speed has only positive values.

C <em>Wrong</em>. Speed has only positive values.

The pressure on 30 milliliters of an ideal gas increases from
Nana76 [90]

V1 = 30 mL

P1 = 760 torr

P2 = 1520 torr

V2 = ?

applying Boyle's Law

P1*V1 = P2*V2

760 torr * 30 mL = 1520 torr * V2

V2 = 760 torr * 30 mL / 1520 torr

( C ) is correct

Consider the single‑step, bimolecular reaction. CH3Br+NaOH⟶CH3OH+NaBr When the concentrations of CH3Br and NaOH are both 0.120 M
GarryVolchara [31]

Answer:

Explanation:

CH₃Br+NaOH⟶CH₃OH+NaBr

It is a single step bimolecular reaction so  order of reaction is 2 , one for CH₃Br and one for NaOH .

rate of reaction = k x [CH₃Br] [ NaOH]

.008 = k x .12 x .12

k = .55555

when concentration of CH₃Br is doubled

rate of reaction = .555555 x [.24] [ .12 ]

= .016 M/s

when concentration of NaOH  is halved

rate of reaction = .555555 x [.12] [ .06 ]

= .004  M/s

when concentration of both CH₃Br and Na OH is made 5 times

rate of reaction = .555555 x .6 x .6

= 0.2 M/s
