Answer:

But without plate tectonics, Earth will simply stop making new ones. The mountains we have now would erode over a few million years, turning into low, rolling hills. Our planet would eventually flatten out, with more land ending up underwater. On the bright side, there'd be fewer natural disasters.

Explanation:

that is what would happen

Answer:All life would die!!

Explanation:The Earth's oceans and continents would no longer exist if the plates stopped moving. Everything would dry up and flatten out. The atmosphere would build up CO2 and could become uncomfortably hot and difficult to breathe.

Explanation:

The graph of Boyle's law is known as pressure-volume graph or PV curve. It is as follows:

As observed from the graph above, pressure increases with a decrease in volume, and vice versa. Thus, pressure is inversely proportional to volume. Other parameters (temperature and amount of gas) are constant in the graph above.

Volume is on the x-axis and pressure, on the y-axis. The equation of the curve is PV = k, which is the equation of Boyle's law. The curve is hyperbolic in nature having two asymptotes: P = 0 (horizontal) and V = 0 (vertical).

As volume tends to positive infinity, pressure tends to zero, and we get the horizontal asymptote, P = 0.

Horizontal asymptote, P=0

When volume approaches zero, pressure approaches infinity, and it results in the vertical asymptote, V = 0.

The graph which shows the pressure-volume relationship expected for an ideal gas is: C)  Graph D.

Boyle's states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyle's law is given by the formula:

[tex]PV = k[/tex]

Where;

For the illustration of Boyle's law using a graph, volume is represented on the x-axis while pressure is represented on the y-axis.

Generally, the graph of Boyle's law is a hyperbolic curve with two asymptotes:

Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,  

Decay's reaction :

₈₄Po²¹⁴⇒₈₃Bi²¹⁰+x+y+z

From this decay reaction can be concluded

mass number decreased by 4

atomic number decreased by 1

Then the most suitable are:

Polonium-214 undergoes 1 alpha decay 1 beta decay and 1 gamma emission.

₈₄Po²¹⁴⇒₈₃Bi²¹⁰+₂He⁴+ ₋₁e⁰+ ₀γ⁰

Answer:

According to Avogadro's law which states that equal volumes of all gases under the same condition of temperature and pressure contain equal number of molecules. Therefore, one molecule of hydrogen reacts with one molecule of chlorine to yield two molecules of hydrogen chloride.

The formula of hydrogen chloride is HCl

The particle diagram is found in the attachment below.

Explanation:

The reaction between hydrogen and chlorine to form hydrogen chloride is represented by the equation below

H₂(g) + Cl₂(g) ---> 2HCl(g)

In the reaction equation above, one mole (or one volume) of diatomic hydrogen gas reacts with one mole (or one volume) of diatomic chlorine gas to form two moles (or two volumes) of hydrogen chloride gas. This is in accordance with Avogadro's law which states that equal volumes of all gases under the same condition of temperature and pressure contain equal number of molecules.

Answer:

357 g of the transition metal are present in 630 grams of the compound of the transition metal and iodine

Explanation:

In any sample of the compound, the percentage by mass of the transition metal is 56.7%. This means that for a 100 g sample of the compound, 56.7 g is the metal while the remaining mass, 43.3 g is iodine.

Given mass of sample compound = 630 g

Calculating the mass of iodine present involves multiplying the percentage by mass composition of the metal by the mass of the given sample;

56.7 % = 56.7/100 = 0.567

Mass of transition metal = 0.567 * 630 = 357.21 g

Therefore, the mass of the transition metal  present in 630 g of the compound is approximately 357 g

Answer:

Explanation:

the oxygen in the air and water from the rain caused oxidation causing the copper wire to become tarnished.

The statement that describes a change resulting from the chemical properties of the wire is it becomes tarnished. The correct option is C.

Chemical properties are those properties that are not always shown physically, but they came out of a chemical reaction. Chemical properties are pH, solubility, toxicity, the heat of combustion, flammability, reactivity, etc.

The copper wire, when left out in the environment, becomes tarnished, due to the air and moisture present in the environment. The meaning of tarnished means it loses its luster or its quality.

Copper is a shiny, soft, and brown-colored metal. It is usually used in making wire used for electricity.

Thus, the correct option is C. It becomes tarnished.

The type of bond is determined by the difference in electronegativity of the atoms. Hence, option D is correct.

A chemical bond is what holds atoms together in molecules.

The ability of an atom to attract a pair of electrons in a chemical bond is called its electronegativity. The difference in electronegativity between two atoms determines how polar a bond will be.

Answer: the reliability will be worse

Explanation:

Suppose we used 0.5 M NaOH to titrate our vinegar sample instead of 0.1 M.

Now by using 0.5M instead of 0.1M we are increasing the concentration of NaOH,

We know that  the moles used = Volume x concnetration.

so for the same no of moles, if the concentration increases, the volume decreases.

Hence it will consume less NaOH.

now Since the volume decreases, the titration volume of less number will increase the % error.

Therefore the reliability will be worse.      

The effect that the concentration of the added base has on the reliability of the results of the titration in question is; The reliability will be worse.

We are told that;

0.5 M NaOH is to be used to titrate a vinegar sample instead of 0.1 M.

Now, 0.5 M means a concentration of 0.5 and since it is higher than 0.1M, it means the concentration of NaOH will increase.

Formula for number of moles used is;

n = V × M

Where;

n is number of moles

V is volume

M is concentration

We can see that number of moles is directly proportional to the volume and concentration.

Thus, if the number of moles remains unchanged, as we have increased the concentration, it means that the volume will decrease.

Thus, lesser volume of NaOH will be used and as a result of this decrease in volume, there will be a greater possibility of error.

In conclusion, we can say that the reliability will be worse.

Answer:

2.652 g/h.

Explanation:

Burn rate (in mg/min) = 44.2 mg/min

Burn rate (in m/h) =?

We'll begin by converting 44.2 mg/min to g/min. This can be obtained as follow:

1 mg/min = 0.001 g/min

Therefore,

44.2 mg/min = 44.2 mg/min × 0.001 g/min / 1 mg/min

44.2 mg/min = 0.0442 g/min

Finally, we shall convert 0.0442 g/min to g/h. This can be obtained as follow:

1 g/min = 60 g/h

Therefore,

0.0442 g/min = 0.0442 g/min × 60 g/h / 1 g/min

0.0442 g/min = 2.652 g/h

Therefore, 44.2 mg/min is equivalent to 2.652 g/h.

Thus, the burn rate (in m/h) is 2.652 g/h.
