Is hydrochloric acid and calcium carbonate a first order reaction?
No, the reaction between hydrochloric acid and calcium carbonate is not a first order reaction. It is a decomposition reaction where the rate of reaction will not be constant as the concentration of the reactants change over time.
Explain why a large increase in the intake of calcium can pose a health problem?
Excessive intake of calcium can lead to hypercalcemia, a condition where there is too much calcium in the blood. This can cause symptoms such as kidney stones, abdominal pain, and muscle weakness. Over time, it may also increase the risk of cardiovascular issues and impaired kidney function.
How is concentration of hydronium ions affected when a solution of acid is diluted in water?
When a solution of acid is diluted in water, the concentration of hydronium ions decreases. This is because the dilution increases the volume of the solution, causing the same amount of acid to be spread out over a larger volume. As a result, the concentration of hydronium ions in the solution decreases.
What are the disadvantages of using calcium chloride in concrete?
One disadvantage of using calcium chloride in concrete is that it can lead to corrosion of reinforcing steel, which weakens the structure over time. Additionally, it can increase the rate of drying, potentially causing cracking and reducing the overall durability of the concrete.
What happens when chlorine gas is passed over calcium hydroxide?
They will undergo an acid base reaction and the products would be calcium chloride, calcium chlorate and water.
How is urine calcium 24 hour calculation done?
To calculate urine calcium over 24 hours, a patient collects all urine produced in a 24-hour period in a designated container. At the end of this period, the total volume of urine is measured. A sample from this collection is then analyzed in a laboratory to determine the calcium concentration, which is typically reported in milligrams per liter. The total calcium excretion is then calculated by multiplying the calcium concentration by the total urine volume in liters.
How does high hydroxide ion concentration do to a solution?
In this case the pH increase over 7.
How does coffee consumption contribute to calcium loss in the body?
Coffee consumption can lead to calcium loss in the body because it contains compounds that can increase the amount of calcium excreted through urine. This can potentially weaken bones over time if calcium intake is not sufficient to offset the loss.
Is hydrochloric acid and calcium carbonate a first order reaction?
No, the reaction between hydrochloric acid and calcium carbonate is not a first order reaction. It is a decomposition reaction where the rate of reaction will not be constant as the concentration of the reactants change over time.
Is an over-the-counter drug test as accurate as a laborator drug test?
No, a lab test can devoldge a percentage of concentration in a sample, and an over the counter only presents whether a substance is present or not. But they do that pretty well!!!
What does investegation mean in science?
You have to state whether or not your hypothesis was supported by the experiment and then explain why or why not. e.g. The hypothesis, if the concentration of the hydrochloric acid is increased, the change in weight of the calcium carbonate will increase, was supported by the experiment that was conducted. There was a notable difference in the change in weight of the calcium carbonate between the different concentrations. The data was reliable as the data was consistent over the three trials and it supported the hypothesis, which was backed by scientific explanation. Acids with a higher concentration contain more acidic particles. Because of this, the reaction was more likely to happen and happened over a larger amount of the surface area of the calcium carbonate. There were no anomalies in the data. As stated previously, the data was consistent over the three trials. Make sure you explain how reliable the data was and why or why not

How would the measured value of specific heat be affected if some boiling water were carried over with the sample?
If boiling water were carried over with the sample, it would increase the measured value of the specific heat. The excess heat energy from the boiling water would contribute to raising the overall temperature of the sample, leading to a higher specific heat value being calculated.
What has the highest concentration of hydroxide ion?
The highest pH on the scale is 14. But pH over 14 is also possible: for example a sample of 1o M sodium hydroxide solution has a pH of 15.
How is concentration of hydronium ions affected when a solution of acid is diluted in water?
When a solution of acid is diluted in water, the concentration of hydronium ions decreases. This is because the dilution increases the volume of the solution, causing the same amount of acid to be spread out over a larger volume. As a result, the concentration of hydronium ions in the solution decreases.
how to decrease margin of error in probability sampling?
With probability sampling you have no control over the units that are sampled. So the only way to reduce the margin of error is to increase the size of the sample.
Does a Quota Sample represent the whole population?
yes because the quota sample include the random sample and when we have over estimation we will use the quota sample
