In your own words, please explain how to name acids.
Answer:
Acids are named based on their anion — the ion attached to the hydrogen. In simple binary acids, one ion is attached to hydrogen. Names for such acids consist of the prefix “hydro-“, the first syllable of the anion, and the suffix “-ic”. Complex acid compounds have oxygen in them.

If an atom has a diameter of 395 pm,
what is its radius?
Answer:
197.5pm
Explanation:
Given parameters:
Diameter of the atom = 395pm
Unknown:
Radius of the atom =?
Solution:
Radius is the half of diameter;
Radius = [tex]\frac{diameter}{2}[/tex]
Radius = [tex]\frac{395}{2}[/tex] = 197.5pm

When you climb to the top of a water slide, you are gaining:
O A. gravitational kinetic energy.
B. chemical potential energy.
c. gravitational potential energy.
D. chemical kinetic energy.
Answer:
C
Explanation:
You climbing the water slide gives you potential energy and your building gravitational eneergy.
When we climb the top of a water slide we are gaining gravitational kinetic energy. That is we are moving through the surface and thus we experience both kinetic energy and gravitational energy.
What is kinetic energy?Kinetic energy of a body is generated by virtue of its motion. Gravitational energy is a form of energy by which the an object attracts other object to its center of mass. Both forms of energy are directly proportional to the mass of the object.
Potential energy is generated by virtue of the position and height of the object. As the height from surface increases, potential energy increases. Potential energy and kinetic energy together called as mechanical energy of an object.
When starts moving our potential energy is converting to kinetic energy. Hence, when we climb the top of a water slide kinetic energy starts to increase. Thus, option A is correct.

Benzoic acid, C6H5COOH, is another derivative of benzene. The pH of an aqueous solution of benzoic acid at 298 K is 2.95. Determine the concentration of hydroxide ions in the solution,
Answer:
[OH⁻] = 8.91x10⁻¹²M
Explanation:
In aqueous solutions, the [OH] and [H⁺] are associated in the equation of hydrolisis of water:
1x10⁻¹⁴ = [OH⁻] [H⁺]
With pH, we can solve for [H⁺] and obtain, the [OH⁻] using this equation:
pH = -log [H⁺]
[H⁺]= 10^-pH
[H⁺] = 1.122x10⁻³M
1x10⁻¹⁴ = [OH⁻] [1.122x10⁻³M]
[OH⁻] = 8.91x10⁻¹²Mhow can you test a sample of soil for acidity or alkalinity
Answer:
Scoop a soil sample into a fresh container, add 1/2 cup of water, and mix. Then, add 1/2 cup of baking soda. If the soil bubbles or fizzes, the soil is acidic. The reaction you're seeing is the result of acidic soil coming into contact with an alkaline substance (baking soda).

How many moles of NaCl could be found in 0.4 L of a 0.9 M solution? Round your answer to
two decimal places.
Answer:
0.36mol
Explanation:
Given parameters:
Volume of NaCl = 0.4L
Molarity = 0.9M
Unknown:
Number of moles = ?
Solution:
To find the number of moles, the molarity of a solution is the amount of solute contained in a solution.
Molarity = [tex]\frac{number of moles}{volume}[/tex]
Number of moles = molarity x volume
Insert the parameters and solve;
Number of moles = 0.4 x 0.9 = 0.36mol

10 g of copper is heated and the mass increases to 12.5 g. What is the mass of the copper in the new substances?
Answer:
10g
Explanation:
The amount of copper in the heated mass of the new substance produced is still 10g because in any chemical action, mass is always conserved.
According to the law of conservation of matter "matter is neither created nor destroyed in a chemical reaction". The change in mass is only due to oxygen gas that combines with the new copper formed or other substances that joined the mass. The substance will still have the same amount of copper as the original one. Since we started with 10g of copper, we end with 10g of copper.how is a solute and a solvent different
what is the density of a 100g piece of titanium if a 10g piece of titanium has a density of 4.506g/cm3?
Possible answers:
A: 45.06g/cm3
B:4.506g/cm3
C: 9.1g/cm3
D: 91g/cm3
Answer:
B. Density stays the same no matter how much of a substance there is.
Explanation:
Density of the substance is the same and it is the measure of its mass per unit volume. Thus, the mass of titanium per 1 cm³ is 4.506 g which is the same for 10 g, 100 g or whatever the mass.
What is density ?Density of a substance is the measure of its mass per unit volume. It describes how closely its particles are packed. Density of an object depends on its bond type, temperature and pressure.
The more denser the object is , more will be its mass distribution per unit volume. Substances denser than water will sink on it otherwise they float on water.
Density is constant for a substance, the distribution of given mass per unit volume is same for all masses. Hence, the density of 100 g Ti is same as that of 10 g. i.e., 4.56 g/cm³.
