Answer:
pH>7
sour taste
donate H+ ions
turn litmus paper from blue to red
Explanation:
The redshift<span> of distant </span>galaxies<span> means that the Universe is probably </span>expanding. If we then go back far enough in time, everything must have been squashed together into a tiny dot and the rapid eruption from this tiny dot was the Big Bang. Another piece of evidence could be that because light takes a long time to travel across the Universe, when we look at very distant galaxies or stars we are also looking back in time. This shows us that galaxies a long time ago were quite different from those today, showing that the Universe has changed. This fits better with the Big Bang theory than the Steady State theory
The coefficient of Fe is 2, Cl is 2, and product would be 2 as well.
Answer is 2.
I believe the answer to this is;
Substances that make up a mixture RETAIN their own properties once they are combined to form a mixture.
I believe the answer is RETAIN because the combination in question is a MIXTURE. A mixture is a combination of various substances. In the case of mixtures, all the substances retain their own properties. That is; they remain the way they are and do not change. An example of a mixture is air. And to prove that air is a mixture;
The components of air retain their individual properties.
The components of air cannot be represented by a chemical formula
When the components of air combine, they do not show any form of chemical change, like heat release, change in pressure.....
Hope i helped, have a nice day.
