how can you test a sample of soil for acidity or alkalinity​

Answers

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).

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

Answers

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.

a) ionic and covalent bonding​

Answers

Answer:

Ionic bonds - an intramolecular force exist in a nonmetal and metal compounds such as NaCl. The Na donate 1 electon to Cl to complete its octet rule.

Covalent bond - an intramolecular force exist in a nonmetal and nonmetal compounds such as bonds O2, Cl2, CO2, sugar, proteins and most of organic compounds and biomolecules by sharing electrons to bond.

There are two types of covalent bonds: polar and nonpolar. Polar bond is a bond between two different nonmetal atoms of different electronegativities. While nonpolar bond is a bond between the same atom or two differenct atoms of the same electronegativities (if there is). Their electronegativities pull will cancel so that their overall polarity is zero.

Answers

Answer:

B

Explanation:

I did it

Neither physical not chemical changes alter the atomic structure of a substance. The correct option is b.

What are chemical changes?

When one chemical substance is transformed into one or more different substances, such as when iron becomes rust, a chemical change occurs.

Chemical changes occur as a result of chemical reactions, and the resulting substances have different properties due to the different arrangements of their atoms and molecules.

Physical changes affect a chemical substance's form but not its chemical composition.

Physical changes can be used to separate mixtures into their component compounds, but not to separate compounds into chemical elements or simpler compounds.

Physical or chemical changes have no effect on a substance's atomic structure.

Thus, the correct option is b.

Answers

Answer:

The initial temperature of the metal is 84.149 °C.

Explanation:

The heat lost by the metal will be equivalent to the heat gain by the water.  

- (msΔT)metal = (msΔT)water

-32.5 grams × 0.365 J/g°C × ΔT = 105.3 grams × 4.18 J/g °C × (17.3 -15.4)°C

-ΔT = 836.29/12.51 °C

-ΔT = 66.89 °C

-(T final - T initial) = 66.89 °C

T initial = 66.89 °C + T final

T initial = 66.89 °C + 17.3 °C

T initial = 84.149 °C.

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.

Answers

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.

[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⁻] = 8.91x10⁻¹²M
