Answer: $H^+$ , water

Explanation:

A base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water and an acid is defined as a substance which donates hydrogen ions $(H^+)$ in water.

$BOH\rightarrow B^++OH^-$

$HX\rightarrow H^++X^-$

Neutralization reaction is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule.

$H^+X^-+B^+OH^-\rightarrow B^+X^-+H_2O$

What is the gauge pressure (in atm) in a 25.0°C car tire containing 3.81 mol of gas in a 31.5 L volume? (Enter your answer to at

bagirrra123 [75]

Answer:

Explanation:

Given

Temperature of gas $T=25^{\circ}C\approx 298\ K$

Volume of gas $V=31.5\ L\approx 31.5\times 10^{-3}\ m^3$

no of moles of gas $n=3.81\ mol$

Using Ideal gas Equation to find the Pressure of gas

$PV=nRT$

where P=Absolute Pressure

V=Volume

R=Universal gas constant

T=Temperature

$P\times 31.5\times 10^{-3}=3.81\times 8.314\times 298$

$P=\frac{3.81\times 8.314\times 298}{31.5\times 10^{-3}}$

$P=299.66\ kPa$

And we know Atmospheric Pressure is $101.325\ kPa$

Therefore Gauge pressure is given by

$P_{gauge}=P-P_{atm}$

$P_{gauge}=299.66-101.325$

$P=198.34\ kPa$

Anyone know how to do this

Charra [1.4K]

The answer to your question is: Yes.

To solve each and every one, write the two given numbers in place of their letters in the given equation, and then solve the equation for the letter that's left.

For example, let's do #1 together. I'll do all the work, and you just watch.

#1 says that s=d/t. It also tells us that 'd' is 4 and 't' is 2. So here's a great idea: Why don't we write '4' where it says 'd', and write '2' where it says 't', and then see what we've got ?

s = 4/2

Wow ! We know that 4/2 is 2 . So s=2 and that's exactly the answer to the question !

Now it's YOUR turn. Do the next 25 problems the same way.

How much work is done when a girl applies a force of 80 N to move an object 4 m, and then moves the object 1 m back?

eduard

Answer:

$w = \underline{{ \boxed{400 \: J }}}$

Explanation:

$work \: done = \boxed{force \times distance} \\ w = 80 \times (4 + 1) = 80 \times 5 \\ w = \underline{{ \boxed{400 \: J }}}$

With the aid of a diagram describe regular and diffuse reflection

Arlecino [84]

Answer:

Regular reflection occurs when a beam of light falls on a smooth and polished surface and irregular reflection occurs when a beam of light falls on a rough surface. Since the surface is uneven, from different points light rays get reflected in different directions and give rise to irregular reflection.

_____ is amount of “ground” an object moves from its starting point and ______ is how much “ground” and object covers in total.

laiz [17]

Displacement is the amount of "ground" and object moves from it starting point and distance is how much "ground" an object covers in total. Displacement by definition is moving of something from its place or position and distance by definition is the amount of space between two things (in this case the starting position and ending position).ΥΤ-ΤΟΝΙХWΙLSΟΝ
