Acids increase the concentration of hydronium ions in solution by donating hydrogen ions to water molecules.
Answer:true
explanation:
If the hydronium concentration increases, the pH decreases, causing the solution to become more acidic. This happens when an acid is introduced. As H+ ions dissociate from the acid and bond with water, they form hydronium ions, thus increasing the hydronium concentration of the solution

Explanation

One benefit of the giant octopus laying many eggs is to increase the chance that more individuals will survive to maintain the population.
What is Survival rates?For organisms that serve as prey for another organism in the same ecosystem, the more their reproductive capacities, the better the chances of the population's continued existence in the ecosystem.The benefit derived from laying many eggs by the octopus is that it increases the chance that more individuals will survive to maintain the population.
Since only 5% of the number of offspring produced by octopuses only make it to adulthood, this means that the higher the number of offspring produced, the higher the chances of more making it to adulthood.The giant octopus lays 20,000 to 100,000 fertilized eggs. after hatching, most octopuses become prey to larger marine organisms, and less than 5% will reach adulthood to reproduce.
Therefore, One benefit of the giant octopus laying many eggs is to increase the chance that more individuals will survive to maintain the population.

Suppose a certain scale is not calibrated correctly, and as a result, the mass of any object is displayed as 0. 75 kilogram less than its actual mass. What is the correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale?
The correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is; 1
What is the Correct Scale Calibration?We are told that a certain scale is not calibrated correctly,
Mass displayed = 0.75 kg (less than its actual mass).
The scale of display = 1
Thus, the correlation between actual mass and displayed mass is 1 due to the fact that correlation is independent of change of origin and scale and correlation between any value and value minus 0.75 will be one.
Thus, the correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is 1.

The moment of inertia about the axis of a solid cylinder is _____ the moment of inertia of a cylindrical shell having the same mass and radius.
The moment of inertia about the axis of a solid cylinder is less than the moment of inertia of a cylindrical shell having the same mass and radius.
How to calculate moment of inertia?Mathematically, the moment of inertia for a solid cylinder is calculated by using this formula:
I = (1/2)mr²
Where:
m is the mass.r is the radius.In conclusion, the moment of inertia about the axis of a solid cylinder would be less than the moment of inertia of a cylindrical shell that has the same mass and radius because the mass of the solid cylinder must be taken near the axis of rotation, which makes it smaller.

A student reads in a newspaper that the soil in his area contains high levels of arsenic. Based on this information, he believes that his fellow high school classmates have this metal present in their bodies. To test his hypothesis, he conducts an investigation of the soil in his school yard to see if it is contaminated with arsenic. He tests seven different areas around the school and finds high levels of arsenic in each. He concludes that the students at the school must have high levels of arsenic in their systems as well. Which of these is the best evaluation of his conclusion?
The best evaluation of his conclusion is it is flawed because he did not test the students to see if their bodies contained metal arsenic.
What is arsenic?Arsenic is an element that is usually found mixed with sulfur and other metals.
Its heavy exposure can cause fatalities and its exposure for a long time can damage the liver, skin, kidney, etc.
In the experiment, he doesn't test students for correct results, so the experiment is flawed.

A patient takes a medication with a half life. initially, there are 11 milligrams of the medication in the patient's system. after 70 minutes there are 7 milligrams. after how many minutes will there be only 3 milligrams remaining in the patient's system? round your answer to the nearest whole number, and do not include units.
Using an exponential function, it is found that there will be only 3 milligrams remaining in the patient's system after 201 minutes.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, initially, there are 11 milligrams on the patient's system, hence A(0) = 11. After 70 minutes there are 7 milligrams, hence A(70) = 7, and this is used to find r.
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]7 = 11(1 - r)^{70}[/tex]
[tex](1 - r)^{70} = \frac{7}{11}[/tex]
[tex]\sqrt[70]{(1 - r)^{70}} = \sqrt[70]{\frac{7}{11}}[/tex]
[tex]1 - r = \left(\frac{7}{11}\right)^\frac{1}{70}[/tex]
1 - r = 0.99356387084
r = 1 - 0.99356387084
r = 0.00643612916
Hence the equation for the amount after t minutes is:
[tex]A(t) = 11(0.99356387084)^t[/tex]
In will be of 3 mg when A(t) = 3, hence:
[tex]A(t) = 11(0.99356387084)^t[/tex]
[tex]3 = 11(0.99356387084)^t[/tex]
[tex](0.99356387084)^t = \frac{3}{11}[/tex]
[tex]\log{(0.99356387084)^t} = \log{\left(\frac{3}{11}\right)}[/tex]
[tex]t\log{(0.99356387084)} = \log{\left(\frac{3}{11}\right)}[/tex]
[tex]t = \frac{\log{\left(\frac{3}{11}\right)}}{\log{(0.99356387084)}}[/tex]
t = 201
There will be only 3 milligrams remaining in the patient's system after 201 minutes.

Christine wants to buy a bicycle for her little brother. she receives a coupon in the mail for 5% off of a bicycle purchased at bikes and wheels. the bicycle her brother wants is $79. if she already has $50 saved, how much more does she need to purchase the bicycle using the coupon?
The amount she needs more to purchase the bicycle using the coupon is = $25.05
Calculation of total costThe coupon Christine received from the mall = 5% off sales
The cost of the bicycle the brother wants is = $79
The amount she has saved is = $50
The amount she needs more to purchase the bicycle using the coupon is = X
But, 5% of 79 = 5/100× 79
= 395/100 = $3.95
This means that given the coupon she will purchase the bicycle = 79 - 3.95 = $75.05
Therefore X = $75.05 - $50
= $25.05
Therefore, the amount she needs more to purchase the bicycle using the coupon is = $25.05
