Why is having hydrochloric acid in our stomach harmful?
Hydrochloric acid in our stomach is necessary for breaking down food and killing bacteria. However, if there is an excess of acid or if the stomach lining is damaged, it can lead to conditions such as acid reflux, ulcers, and gastritis. Chronic exposure to high levels of hydrochloric acid can potentially damage the stomach lining and cause health issues.
What color is methyl orange when hydrochloric acid is added?
The effect of dilute HCl on the colors of the methyl orange will most likely be red. This is assumed because of both most likely having a pH of 3.1, which will end up red.
What is the benefit of having hydrochloric acid in your stomach?
Hydrochloric acid reduces the pH of the stomach fluids to 1.5-2. At such a low pH, most microorganisms are unable to survive. So, when we ingest microorganisms with our food, they are killed by the acidic conditions in our stomach. That is why, people don't fall sick all the time.
What does an excess of hydrochloric acid mean?
It means that there is more hydrochloric acid than is required to cause the reaction. its to do with ratios for example if you needed it to react with water (hypothetically) and the ratio required was 1:1 (again hypothetically) and you had 200ml of acid and only 100ml of water then 100ml would react of each giving you 200ml of the reacted "hydrochloric acidy water" (made that up its been a while since i done chemistry) and 100 ml "excess" of pure hydrochloric acid. If its a practical experiment you are carrying out they tell you to use an excess for two reasons. to make sure you have enough to give the desired affect without having to be too precise and also unless you are working in optimal conditions ratios are never perfect. Depends on what level of chemistry you are at?
How do you color concrete?
AnswerIf you want to add color to an existing floor:Add an oxidizing agentPaint it. You should use a floor paint. Priming it would be of value. Make sure to sweep and mop first.If you are looking at having a new, colored, floor poured:The most common way to color concrete is by adding a tint color to the base mix.

Scoville and Hoover are just two suppliers. I would consult someone at a concrete materials supply house such as McCann. On the web you can start with a search for concrete colorants and Stamped concrete.

What does it mean to believe in something?
Believing in something means having faith or confidence in its truth or existence, often without concrete proof. It involves trusting in the validity of an idea, concept, or belief system.
What is it called to believe without having proof?

true
What reinforces concrete?
concrete is basically strong in compression....anything which is having tensile strength reinforces concrete To reinforce concrete company's will use a fibre mesh which has loads of microscopic fibres and they bind the concrete together stronger. also in concrete slabs builders will usually tread re-in-forced steel grids into the mix
