If i have an 86 and i don’t do a 50 point assignment, what will my grade be in the class?

1 answer:

7 0

Well you are at a 86% so this is considered a "B" grade on an average grade scale. If you take 50 points we would need to know the Total point you could have got in that class to be able to see how much a percent was the assignment work and then take that percentage of the assignment and subtract it from the 86% to see where on the scale you would fall in after the assignment points were taken off. Hope this helps :)

What is the volume if 1.5 mol of gas has a pressure of 700 torr at 15°C?

Tasya [4]

Answer:

V = 38.48 L

Explanation:

Given that,

No. of moles = 1.5 mol

Pressure, P = 700 torr

Temperature, T = 15°C = 288 K

We need to find the volume of the gas. The ideal gas equation is given by :

$PV=nRT\\\\V=\dfrac{nRT}{P}\\\\V=\dfrac{1.5\times 62.36\times 288}{700}\\\\V=38.48\ L$ , R = L.Torr.K⁻¹.mol⁻¹

So, the required volume is equal to 38.48 L.

When a person in the hospital is given fluids intravenously, the fluid is typically a saline (salt) solution with about the same

Sati [7]

Answer:

Swelling of the red blood cells occurs.

Explanation:

Distilled water makes the blood hypotonic ,. that is a less concentrated solution, to the body tissues including the red blood cells.
Therefore the water will enter the red blood cells and may cause them to lyse or swell.
Additionally , water will enter the tissue spaces and cause sweling.
But in the case of a hypertonic solution , ( a salt or saline solution ) , This swelling does not happen because the concentration of the saline will be equal or more than the blood. 
Thus the water will flow only from the blood to the solution. This will not cause swelling.
But too much of salt is also not recommended.

Which statement describes global winds?

sergejj [24]

Answer:

They blow away from poles to the equator.

Explanation:

Hello,

In this case, we must take into account that global wind systems are formed by the constant increase in the temperature of the Earth’s surface. Thus, they drive the oceans’ surface currents. In such a way, we can say wind is the basic movement of air from an area of higher pressure to an area of lower pressure, for that reason they blow away from the poles to the equator.

Best regards.

Why is Earth's surface rarely impacted by large objects that enter Earth's 13 points

Hatshy [7]

Answer:

A.Because Earth's atmosphere causes most objects to burn up before they reach the surface.

Explanation:

The Earth's surface is rarely impacted by large objects that enters because the atmosphere causes most of the objects to burn up before they reach the surface.

There are different layers of the earth atmosphere which carries various amount of energy and energetic particles.

When a massive and a high solar object or dust or rocks are directed towards the earth, they are either deflected or burnt upon their passage through the atmosphere.
These energetic particles have ionizing properties and causes the solar particles to burn up.
This way the earth's surface is shielded from any impact of any sort.
