pH:
Definition:
A value from 0 to 14 is used to specify how acidic or basic a compound is when it is dissolved in water
Used to measure the pH of substances by determining their hydrogen ion concentration
A compound that increases hydroxide ions (OH−) when it is dissolved in a solution
A compound that increases hydrogen ions (H+) when it is dissolved in a solution
A value from 0 to 14 is used to specify how acidic or basic a compound is when it is dissolved in water= pH
A compound that increases hydroxide ions (OH−) when it is dissolved in a solution= Acid
A compound that increases hydrogen ions (H+) when it is dissolved in a solution= ions
Used to measure the pH of substances by determining their hydrogen ion concentration= base
Answer: pH goes with A value from 0 to 14 is used to specify how acidic or basic a compound is when it is dissolved in water

How is a mixture such as a plate of pasta different from a mixture such as air
Answer:
Well there is a lot of differences between the two. Its called homogeneous and Heterogeneous mixtures. Homogeneous mixtures are all the substances are evenly distributed throughout the mixture (salt water, air, blood). Heterogeneous mixtures are the substances that are not evenly distributed (chocolate chip cookies, pizza, rocks). So Pasta with sauce and meatballs is heterogeneous and air is homogeneous

Explanation:
when salt dissolves into water does it change its state
Answer:
no it doesn't change back
fine here When you dissolve salt in water, the sodium chloride dissociates in Na + ions and Cl - ions, which may be written as a chemical equation : NaCl (s) → Na + (aq) + Cl - (aq) Therefore, dissolving salt in water is a chemical change. The reactant (sodium chloride, or NaCl) is different from the products (sodium cation and chlorine anion).
Why does the Earth experience two high and two low tides each day?
The moon orbits the Earth twice as fast as the sun.
The moon orbits the Earth completely once per day.
The moon and the sun create their own high and low tides.
The moon passes over the same location above the Earth's surface twice per day.

#Bottom left:-
Denoted to Whole branching of KCl h.ce it's repeating atom group
#Last
CH_4 's extended structure is shown hence it's extended structure

What is the working resistance of a bulb that takes a current of 0.25 A when it is connected to 220V mains supply?
Answer:
880 Ω (Ohms)
Explanation:
To calculate Resistance from Potential Difference (Volts) and Current (Amps), you use the equation R = V/I
So,
R = 220/0.25
R= 880

the figure shows the great ocean conveyor belt. which best describes what this model represents?
A. The model shows how ocean currents change the salinity of water.
B. the model shows how ocean currents move heat energy around earth
C. the model shows how salinity of water affects its density
D. the model shows how the density of water differs between the north Atlantic and other parts of the ocean.
Answer:
d
Explanation:
The ocean conveyor belt shows the movement of the oceanic water and the salinity. The model represents the density of the water in different regions of the world. Thus, option d is correct.
What are ocean conveyor belts?Ocean conveyor belts are the oceanic current movement in their oceans across others and how the water moves across the water bodies across the globe.
The model shows that high salinity water gets heavy and sinks in the ocean of North Atlantic but the water of the Indian and the pacific oceans are less saline and remains at the surface.
Therefore, option D. the water differs in oceans based on density.

A pneumonic device is a memorization tool that helps you remember things. For example, if you can read music you probably have heard, “Every Good Boy Does Fine” to learn the names of the lines on the treble clef EGBDF. Or maybe your math teacher taught you, “Please Excuse My Dear Aunt Sally,” to help you remember the order of operations. It is now your turn to think of a pneumonic device to remember the water cycle in order. Write your pneumonic device below.

A person riding a bicycle wants to move the bicycle forward. She moves her legs up and down on the bicycle's pedals. Then the rider wants to stop the bicycle. She stops pedaling and the bicycle slows. She takes one of her feet off a pedal and puts her foot on the ground to stop the bicycle and stay upright.
Which of these best identifies a pathway of systems in the rider's body, as described in this scenario?
