Answer:

you can yes soap because the chemicals are safe in it

Explanation:

bleach you can not yes because but has wires cgemucaks than soap

Soap is a weaker base than bleach and it has more hydronium ions than bleach. It lies closer to a neutral pH. Therefore, option (A) is correct.

An acid is capable of donating a proton to another substance and is generally identified by its sour taste.  A base is capable to accept a hydrogen ion from acid and is characterized by a bitter taste and a slippery texture.

Acids can turn blue litmus paper into red while Bases can turn red litmus paper into blue. A base can dissolve in water and when bases chemically react with acids, yield salt, and water as products.

pH = -log [H⁺]

The pH value of the bases lies between 7 to 14. The more the pH value stronger will be the base. The concentration of hydronium ions will be less if the pH value is higher. Therefore, soap has less pH value so it has more hydronium ions.

Answer:

The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39.

Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.

Explanation:

Answer: Your answer is B. Neuron. When you look at the nerve cell you can see the cell body, the dendrites ontop of it, axon is the tail like thing at the bottom and the neuron isn't even part of the nerve cell

Explanation:

Answer:

here

volume of cube = l^3

=2cm^3

=8cm^3

now,

mass=(9.7÷1000)kg

=0.0097kg

volume=8cm^3÷100=0.08

we know that,

density=mass/volume

= (0.0097/0.08)kg/m^3

= 0.12125kg/m^3

Explanation:

the formula to calculate volume of cube is l^3 so here we find the volume of cube using this formula and then we convert gram into kilogram then convert cm into m then by applying the formula of density we find it density

A 2 cm cube made of acrylic has a mass of 9.7 g. The density of the acrylic is 0.12125 kg m3

Density is the mass of per unit volume.

\(Volume of cube = l^3\\=2cm^3\\=8cm^3\)

mass 9.7 kg, converted into kilograms = 0.0097kg

\(Volume \;= \dfrac{8cm^3}{100} = 0.08\)

Calculating the density

\(Density = \dfrac{mass}{volume} \\\\\dfrac{0.0097}{0.08} = 0.12125\;kg\;m^3\)

Thus, the density of the acrylic is 0.12125 kg m^3.

Answer:

As altitude increases in Earth's atmosphere, both air pressure and the amount of oxygen decrease.

At sea level, the air pressure is about 1013.25 millibars (mb) and the concentration of oxygen is about 21%. As you go higher in the atmosphere, the air becomes thinner and less dense, so the air pressure decreases. At the same time, the concentration of oxygen also decreases because there is less air overall to contain oxygen molecules.

This is why it is harder to breathe at high altitudes, such as on a mountain. The air is less dense, so there are fewer oxygen molecules per breath and the body has to work harder to get enough oxygen.

Answer:4: Both Air and Oxygen decrease.

Explanation:This is in accordance with Henry's law. As pressure decreases solubility of gases decreases. Air pressure decreases as we altitude increases and the decrease in oxygen level is the consequence ,

Relative mass does not need to be calculated as it is listed on the periodic table. Potassium's relative atomic mass is around 39.

Answer: The wave interaction described in the scenario is known as constructive interference.

Explanation:

Constructive interference occurs when two waves meet and combine in such a way that their amplitudes add up, resulting in a larger wave. In this case, Max's steady pattern of jumping creates small waves on the trampoline, with a certain amplitude.

When Jimmy starts jumping on the trampoline, his waves combine with Max's waves. If the peaks and troughs of both waves align perfectly, they will add up, resulting in a wave with a larger amplitude. This alignment of peaks and troughs leads to constructive interference, causing Max to go twice as high without any additional effort.

The reason behind this phenomenon lies in the nature of waves. When waves meet, their amplitudes can either add up or cancel out, depending on their relative positions. In the case of constructive interference, the peaks of one wave align with the peaks of the other wave, and the troughs align with the troughs, resulting in an increased amplitude. Conversely, in destructive interference, the peaks align with the troughs, leading to a cancellation or reduction in amplitude.

So, in the scenario, Jimmy's waves align with Max's waves in such a way that their amplitudes combine constructively, resulting in Max going twice as high on the trampoline without exerting any extra effort.

Hot-Water Solutions Groundwater works its way down and is heated by magma, and then reacts with minerals to form a hot liquid solution. H. Dissolved metals and other elements crystallize out of the hot fluid to form new minerals, such as gold, copper, sulfur, pyrite, and galena.

Answer:

What happens to hot water beneath the Earth as it moves up through fractured rock?

Circulating groundwater that comes into contact with the cooling magma is heated and rises to the surface along rock fractures to form either a thermal spring, figmarole, or geyser.

Answer:

they moon and sun are a factor in both of them

Explanation:

Answer:

From our perspective on Earth, two types of eclipses occur: lunar, the blocking of the Moon by Earth's shadow, and solar, the obstruction of the Sun by the Moon. When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. Also they are similar by An eclipse occurs when one celestial object obscures another celestial object. In the case of a solar eclipse, the moon moves between the Earth and the sun, thus obscuring the sun. A lunar eclipse occurs when the Earth moves directly between the sun and the moon. Either type of eclipse can be total or partial.

Decomposers (organisms that break down dead producers and consumers and organic waste) obtain the energy they need to live from chemical bonds of the dead and waste-matter. The energy is transferred both to the decomposer (for growth and development) and to the ecosystem (as heat energy)

Explanation:

Some of the scientific questions that may be answered through the experiment are:

(1) What are the physical changes that may occur in the solution or the indicator when added with acidic/basic solution?

(2) How much of the indicator is needed in order to bring about a significant physical change in the solution to identify its H+ concentration?

if wrong i sry :(

By determining the H+ ion concentration of a solution, we can measure the pH of the solution and thereby to check its acidity. Thus, by doing this experiment, we are answering the question that the what is the pH of the household solutions, and they are acidic or basic?

pH of a solution is the measure of its H+ ion concentration. Mathematically it is the negative logarithm of the H+ ion concentration. The pH of a solution tells it is acidic or basic.

pH of 7 is neutral solution and a pH below 7 is acidic whereas a pH above 7 is basic solution. We can use natural indicators such as cabbage juice to determine the pH of house hold solutions such as  lemon juice, milk, soap solution etc.

A color change of red is given by acidic solutions ad that of blue indicating the basicity. Hence, the scientific question will be to determine pH range of the solutions.
