calculate the volume that will be occupied by 350 ml of oxygen measured at 720 mm hg, when the pressure changed to 630 mm hg
likoan [24]

Answer:

406.45mL

Explanation:

The following data were obtained from the question:

V1 = 350mL

P1 = 720mmHg

P2 = 630mmHg

V2 =?

The new volume can be obtain as follows:

P1V1 = P2V2

720 x 350 = 620 x v2

Divide both side by 620

V2 = (720 x 350) /620

V2 = 406.45mL

The new volume of the gas is 406.45mL

A velocity vs time graph is a graph that shows the relationship between the velocity of an object over time. is plotted on the x
S_A_V [24]
A graph shows a relationship between two variables: independent and dependent. The dependent variable is in the y-axis, while the independent variable is in the x-axis. When it says, plot velocity against time, that means that velocity is in the y-axis in meters per second, and time is in the x-axis in seconds. 

An example of a velocity vs time graph is shown in the attached picture. In this example, the motion is in constant acceleration. This is because it is linear, thereby, the slope is constant. If you want to find the instantaneous velocity at a certain time, create a vertical line from the x-axis until it reaches the diagonal line. Then, draw a horizontal line towards the y-axis to know the value of the velocity.

Which of the following is not the same as 12.5 millimeters? 0.0000125 km 0.00125 hm 0.0125 m 1.25 cm
erma4kov [3.2K]
1 mm (millimeter) = 0.000001 km (kilometer)
12.5 mm = <span>0.0000125 km

1 mm = </span><span>0.00001 hm (hectometer)
12.5 mm = </span><span>0.000125 hm

1 mm = </span>0.001 m (meter)
12.5 mm = 0.0125 m

1 mm = 0.1 cm (centimeter)
12.5 mm = 1.25 cm

So the only one of the answer choices that doesn't equal 12.5 mm is 0.00125 hm, since 12.5 mm is <span>0.000125 hm.

Answer:
</span><span>0.00125 hm
</span><span>

A highway engineer is researching de-icing compounds for clearing ice from streets in winter. She wants a compound that has +2 i
wolverine [178]

Magnesium combined with chlorine.

How?

  • Look at the question .Compound has -1 charge in it .Hence it contains Halogen.
  • Looking at the options Option B and C contain Iodine and chlorine i.e halogens .

Now come to metals side.

  • Potassium has valency 1(Look the Electronic configuration below)

\\ \sf\longmapsto 1s^22s^22p^63s^23p^64s^1

Hence it will contain +1 charge which is omitted directly .

Now come to option C.

  • Magnesium has charge +2(Look at EC below

\\ \sf\longmapsto 1s^22s^22p^63s^2

Hence the compound formed is given by

\\ \sf\longmapsto MgCl_2

Hence option C is correct.
