pH of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

pH is virtually a measure of the relative quantity of free hydrogen and hydroxyl ions in the water. Water that has extra free hydrogen ions is acidic, whereas water that has greater free hydroxyl ions is basic.

<h3>What is a high pH?</h3>

High pH. A waterbody is considered to have a excessive pH if pH exceeds 9 for extended intervals or with excessive frequency. High pH is much less frequent than low pH as a candidate cause, due to the fact anthropogenic sources are acidic more frequently than basic.

<h3>What increases the pH of water?</h3>

Soda ash (sodium carbonate) and sodium hydroxide increase the pH of water to near neutral when injected into a water system. Unlike neutralizing filters, they do no longer motive hardness troubles in dealt with water. Injection structures are a point-of-entry system.

Calculate: A. Mercury has a specific Heat Capacity of 0.14 J/goC. How much heat is needed to raise the thermometer temperature 1

kari74 [83]

Answer:

$\boxed {\boxed {\sf 56 \ Joules}}$

Explanation:

We are given the mass, specific heat, and temperature, so we must use this formula for heat energy.

$q=mc \Delta T$

The mass is 5 grams, the specific heat capacity is 0.14 Joules per gram degree Celsius. Let's find the change in temperature.

ΔT= final temperature - initial temperature
ΔT= 95°C - 15°C = 80°C

We know the variables and can substitute them into the formula.

$m= 5 \ g \\c= 0.14 \ J/ g \ \textdegree C \\\Delta T= 80 \ \textdegree C$

$q= (5 \ g )( 0.14 \ J/ g \ \textdegree C ) ( 80 \ \textdegree C)$

Multiply the first numbers. The grams will cancel.

$q= 0.7 \ J/ \textdegree C(80 \ \textdegree C )$

Multiply again. This time the degrees Celsius cancel.

$q= 56 \ J$

56 Joules of heat are needed.

What causes the Brownian motion of particles in a colloid?

LekaFEV [45]

<u>Answer:</u>

The correct answer option is a) collisions between the particles and surrounding molecules.

<u>Explanation:</u>

The collisions between the particles and surrounding molecules causes the Brownian motion of particles in a colloid.

Brownian motion is the irregular movement of the microscopic particles in a fluid which bombard into each other.

It basically is the result of the molecules of a dispersion medium colliding with the dispersed particles of the phase.

Why does light from the infrared lamp<br> warm the mirror when light from the desk lamp does not?

Sunny_sXe [5.5K]

Answer:

Because the infrared lamp gives off a type of light that the desk lamp does not, and the mirror can only take in the energy from the infrared light.
