Answer:

B. X represents phosphorus

Explanation:

In an isotope symbol, you write the mass number above the atomic number. So the 31 represents the mass of the protons and neutrons of the element added together, and the 15 represents the atomic number or the total number of protons in the nucleus.

Explanation:

plants have stomata at the bottom of their leaves. these allow for CO2 to diffuse in and out of the plant.

Answer: Metals

Explanation:

When an atom accepts an electron negative charge is created on atom and is called as anion.

When atom loses an electron positive charge is created on atom and is called as cation.

The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Thus metals form cations.

Explanation:

The law of conservation of matter states that "matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same."(Virginia)

Hence, the quantity of matter present before and after the candle burn must remain the same in accordance with this law stated above.

Answer:

Electrolytes, particularly sodium, help the body maintain normal fluid levels in the fluid compartments because the amount of fluid a compartment contains depends on the amount (concentration) of electrolytes in it. If the electrolyte concentration is high, fluid moves into that compartment (a process called osmosis).

Explanation:

Answer:

Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help

Balance the amount of water in your body

Balance your body's acid/base (pH) level

Move nutrients into your cells

Move wastes out of your cells

Make sure that your nerves, muscles, the heart, and the brain work the way they should

Sodium, calcium, potassium, chloride, phosphate, and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink.

The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance.

Treatment helps you to manage the imbalance. It also involves identifying and treating what caused the imbalance.

Answer:

Organisms become more complex over time.

Explanation:

We all evolved from the first bacteria, which was relatively simple. We see over time that things become more adapted, slowly adding eyes, lungs, behavioral patterns, and consciousness.

Answer:

F₂ (g) + FeI₂ (aq) →  FeF₂ (aq) +  I₂ (l)

Explanation:

Our reactants are:

F₂ → Fluorine gas, a dyatomic molecule

FeI₂ → Iron (II) iodine

Our products are:

I₂ → Iodine

FeF₂ → Iron (II) fluoride

Then, the reaction is:

F₂ (g) + FeI₂ (aq) →  FeF₂ (aq) +  I₂ (l)

We see it is completely balanced.

Answer:

18. E. 0%

19. D. 25%

Explanation:

Question 18:

Let's use "B" to represent the dominant allele of "light blue skin", and

"b" for recessive "light green skin".

Squidward => BB - light blue skin

Squidward's bride => bb - light green skin

When they cross, they will have the following offsprings:

(BB) × (bb) - Parent

(Bb) (Bb) (Bb) (Bb) - Offspring

All the offspring would be light green skin. The dominant allele of light green skin will express itself over the recessive allele.

Therefore, the chances of Squidward and his bride having light green skin is 0%

Question 19:

Squidward's son => Bb - light blue skin

Squidward's son's bride => Bb - light blue skin

(Bb) × (Bb) - parent

(BB) (Bb) (Bb) (bb) - offspring

They will have the following offspring:

BB and Bb - light blue - 75%

bb - light green - 25%

Chance of having offspring with light green skin is 25%

Explanation:

We first obtain the mole fraction of propane at the start and end;

0.01 = x/0.62 + 0.28 + x

0.01[0.62 + 0.28 + x] = x

0.01[0.9 + x] =x

9 * 10^-3 + 0.0.1x = x

9 * 10^-3 = x - 0.0.1x

9 * 10^-3 = 0.99x

x = 9 * 10^-3/0.99

x = 9.09 * 10^-3

After

For methane

0.62/ 0.28 + 0.62 + 9.09 * 10^-3     = 0.68

For ethane

0.28/0.28 + 0.62 + 9.09 * 10^-3       =0.31

Change in partial pressure of methane = (0.68 - 0.62) * 100kPa = 6 kPa

Change in partial pressure of ethane = (0.31 - 0.28) * 100kPa = 3 kPa

Change in partial pressure of propane= (0.01 - 0.1) * 100kPa = -9 kPa

By adding the decreasing the temperature, the speed of the reaction will not be increased.

The reaction rate, which is a measure of how quickly reactants are consumed as well as products are created, determines the speed of a reaction.

When the temperature is lowered, the molecules move more slowly and collide less. The reaction's speed is slowed as the temperature drops.

Therefore, by adding the decreasing the temperature, the speed of the reaction will not be increased.

Answer:

Thegas should be cooled to -136.5°C.

Explanation:

Volume of a gas is directly proportional to its temperature on the kelvin scale. This is called Charles' law.

Initially, the gas had a volume of 3.0 L at 0°C(273 K).

We have to have the temperature at which the volume of the gas will be 1.5 L.

Let V1=3 L, T1=273 K, V2=1.5 L, T2=?

By Charles' law,

V1/T1=V2/T2

T2

=(V2×T1)/V1

=(1.5 L×273K)/3L

=136.5 K

=(136.5-273)°C

= -136.5 °C

Answer:

The limiting reactant is H₂

Explanation:

The reaction of hydrogen (H₂) and carbon monoxide (CO) to produce methanol (CH₃OH) is the following:

2H₂(g) + CO(g) → CH₃OH(g)

From the balanced chemical equation, we can see that 1 mol of CO reacts wIth 2 moles of H₂. So, the stoichiometric ratio is:

2 mol H₂/1 mol CO = 2.0

We have 500 mol of CO and 750 mol of H₂, so we calculate the ratio to establish a comparison:

750 mol H₂/500 mol CO = 1.5

Since 2.0 > 1.5, we have fewer moles of H₂ than are needed to completely react with 500 moles of CO. In fact, we need 1000 moles of H₂ and we have 750 moles. So, the limiting reactant is H₂.
