Answer:

t represents time, which is the input of the function.

h(t) represents the altitude, which is the output of the function.

After 10 minutes, the hot air balloon is at 60 feet.

Explanation:

Given the function; h(t) = 210 - 15t models the altitude of a hot air balloon over time t, in minutes.

It follows that;

t represents time, which is the input of the function.

h(t) represents the altitude, which is the output of the function.

To obtain h(10), we have;

h(10) = 210 - 15(10)

h(10) = 60 feet

Explanation:

Snowflake Symmetry. All ice crystals (of ordinary 'Ice 1h' that is) have the same basic hexagonal symmetry. The fundamental building block is a unit cell containing four water molecules. Ice crystals can be thought of as made of untold stacks of these unit cells.

Answer:

The distance light travels in a tiny fraction of a second

Explanation:

One meter is defined as the length of the path travelled by light in a vacuum in [tex]\dfrac{1}{299 792 458}[/tex] of a second. It is also equal to the one [tex]\dfrac{1}{10}[/tex] of the distance from the equator to the North Pole. It is one of the fundamental units. It is a SI unit of length. So, the standard definition of 1 mete is the distance light travels in a tiny fraction of a second.

Hence, the correct option is (d).

See explanation

Explanation:

The leaves or needles of evergreen trees lose less water than other kinds of leaves. This means that they are better able to conserve water in  the taiga, a cold biome with long, dark winters.

These conifers possess adaptations that are able to help them survive the long, cold winters and short summers in a typical taiga biome since their needles contain very little sap, which also helps prevent them from freezing.

Answer:

The nickel sulfate will completely mix with the water in the beaker to form a uniform green solution

Explanation:

When the nickel sulfate solution is placed in the bottom of the beaker of water, its molecules will more concentrated at the bottom of the beaker than in other parts of the beaker. Due to this high concentration of nickel sulfate molecules, the molecules will be colliding with one another at a frequent rate. With every collision occurring between the molecules, the molecules will continue to spread out further to other parts of the beaker where there is more space for the molecules and therefore less frequency of collision. Eventually, after many days, the molecules will spread out throughout the whole beaker completely mixing with the water molecules. This process is known as diffusion, which is defined as the movement of molecules from a region of high concentration to a region of low concentration until equilibrium is attained.

The moon is 150 inches far from the earth  to its current location 100 years from now.

Only one celestial object, Earth, which is third from the Sun, is known to support life. Although the Solar System contains enormous amounts of water, only Earth is home to liquid surface water. The oceans cover around 71% of Earth's surface, dwarfing its lakes, rivers, and polar ice.

Because Earth was never an unknown entity to mankind, it was never properly "discovered." Its shared status as a "planet" with other bodies, nevertheless, was just recently discovered.

The moon travels around 251,000 miles from Earth during its apogee, or farthest point from our planet. Solar eclipses that have an annular shape, or a "ring of fire," are among the best examples of apogee in nature.

Thus, the moon is 150 inches far from the earth  to its current location 100 years from now.

Answer:

Explanation:

The question wants us to determine what could be done to change the carbide ion to a neutral carbon atom.

From the given information:

The dark grey ball has a +1 charge, which implies that the positive charge is the proton. Also, the light grey ball is denoted by 0 charge, which signifies that it is a neutron because a neutron usually has no charge, and its mass is equal to the mass of the proton.

Consequently, the -1 charge on the medium grey ball signifies that it is an electron.

In a neutral atom, the number of protons usually equal to the electron number. However, in as much as no overall charge is present from the model of the atom given. We can say that the atom is neutral.

Let also recall that the atomic number is the number of available protons present in the element's atomic nucleus.

Thus, in the given atom.

The total number of proton = 8

The total number of neutron = 9

The total number of electron = 8

Since atomic number relates to the number of protons, the atomic number is also = 8

Answer:

A. Pb(OH)2 + 2HCl → 2H2O + PbCl2

Explanation:

In a balanced reaction, the amount of different atoms in the products must be equal to number of atoms in reactants. With the equations of the problem:

A. Pb(OH)2 + 2HCl → 2H2O + PbCl2

There is 1 atom of Pb in reactants and products.

2 atoms of O in both sides.

4 atoms of H

And 2 atoms of Cl

That means this reaction is balanced

B. 2Pb(OH)2 + HCl → H2O + 2PbCl2

2 atoms of Pb

4 atoms of O in reactants but just 1 in products.

As the amount of oxygen is not equal for reactants and products we can say the reaction is unbalanced.

And right choice is A.

The element that is most stable based on its electron configuration is argon. The correct option is D.

The electron configuration of any atom or molecule in atomic or molecular orbitals is renowned in atomic physics and quantum chemistry.

Noble gases have a stable ns2np6 configuration with their octet completely filled, giving them stability. There is one exception: helium.

The electron configuration is commonly used to describe an atom's orbitals in its ground state, but it can also be used to represent an atom that has ionized into a cation or anion by compensating for electron loss or gain in subsequent orbitals.

8A Group Noble and inert gases The noble gases of Group 8A (or VIIIA) of the periodic table are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

Thus, the correct option is D.

C. Homeostasis

Explanation:

The overall charge of an atom is zero.

Atoms are made up of positively charged particles called protons and negatively charged particles called electrons as well as non-charged particles called neutrons.

Answer:

the molar mass of the components making up Ca(NO₃)₂ are as follows;

Ca - 40 g/mol

N - 14 g/mol

O - 16 g/mol

the molar mass of the compound is calculated as follows;

Ca(NO₃)₂ --> 40 + 2(14 + 16x3)

              = 164 g/mol

1 mol of the compound weighs 164 g

Therefore 0.433 mol = 164 g/mol x 0.433 mol

                                = 71.0g

the mass of 0.433 mol of the compound is 71.0 g

Answer:

It stays the same

Explanation:

From the gas law:

P1V1/T1 = P2V2/T2

P1 = P, V1 = V, T1 = T and P2 = 15.5P, V2 = ? , T2 = 15.5T

Substituting the various variables into the gas law equation:

PV/T = 15.5PV2/15.5T

Make V2 the subject of the formula:

V2 = 15.5TPV/15.5PT

V2 = V.

V1 = V and V2 = V, hence, the volume of the balloon stays the same.
