1. Parents from both species.

2. Because of natural selection.

Explanation:

Answer:yes

Explanation:

Because modern periodic table is designed in such a way that it can accomodate any new elemet which may be discovered in future

We have that for the Question "when and if element 119 is discovered predict where it would be placed on the modern periodic table" it can be said that With the existing information the element 119 will most likely be i the 8th period and the first group of the periodic table

From the question we are told

when and if element 119 is discovered predict where it would be placed on the modern periodic table

Generally

The Periodic table is naturally designed to accommodate new elements based on there properties

Therefore

With the existing information the element 119 will most likely be i the 8th period and the first group of the periodic table

Explanation:

Answer: the heat is rapidly changing

Explanation: as the heat continues to rapidly change so does the chemical as it also starts to change, so in a way you could use the example of a skateboard moving. This is because theres also friction in the skateboard which is made from the two things moving together and the heat is slowly increasing causing a reaction to the skateboard wheels so in a way it can cause more rapid changes

With the increase in heat or temperature, the rate of reaction will increase as more molcules will get kinetic energy for effective collisions.

The rate of reaction can be d as defined the speed at which the products are fromed from the reactants. The rate of a reaction provides information on how much time under which a chemical reaction can be completed.

The rate of a chemical reaction can be defined as the speed of the conversion of the reactants into products with time. Some reactions are instantaneous, while some chemical reactions take time to achieve the final equilibrium.

In some reactions, a catalyst can be used to increase the rate of the reaction.  The catalyst provides the speed to the reaction in both forward and backward reactions by lowering the activation energy.

The pressure of the gaseous reactants increases, and the concentration of gases results in an increase in the rate of reaction.  With an increase in the temperature, the average kinetic energy of the reactant molcules will be raised.

Therefore, more molecules will go under effective collisions. Therefore, the rate of reaction will be increased.

Answer:

[tex]K_{2}CrO_{4} + Pb(NO_{3})_{2} >> 2 KNO_{3} + PbCrO_{4}[/tex]

Reactions:

[tex]K_{2}CrO_{4} + Pb(NO_{3})_{2} >> KNO_{3} + PbCrO_{4}[/tex]

Explanation:

In the reaction, the CrO4(Chromate)  is a compound NO3(Nitrate) is a compound as well.

Ignore the number in front of the reaction first, calculate how many K, Cr, O, Pb and N in the equation for both left and right side.

Left side:   K=2, Cr=1, Pb=1, N=2, O=10

Right side: K=1, Cr=1, Pb=1, N=1, O=7

So we need 3 more oxygen, 1 more nitrogen and 1 more potassium on the right.

If we add a 2 in front of KNO3, there will be 2 potassium, 2 Nitrogen and 6 oxygen, which the reaction complete.

Conclusion:

[tex]K_{2}CrO_{4} + Pb(NO_{3})_{2} >> 2 KNO_{3} + PbCrO_{4}[/tex]

Answer: (D) it is not spontaneous.

Answer:

Pb3O4

Explanation:

According to this question, 3.425g of lead oxide was reduced to form 3.105g of lead in an experiment. Since lead oxide contains both lead (Pb) and oxygen (O) element,

Mass of lead oxide = 3.425g

Mass of lead = 3.105g

Mass of oxygen = (3.425g - 3.105g) = 0.320g

Next, we convert each mass value to mole by dividing by respective molar mass

Pb = 3.105g ÷ 207.2 = 0.0149mol

O = 0.320g ÷ 16 = 0.02mol

Next, we divide each mole value by the smallest (0.0149)

Pb = 0.0149mol ÷ 0.0149mol = 1

O = 0.02mol ÷ 0.0149mol = 1.342

Multiply each ratio value by 3 to get:

Pb = 1 × 3 = 3

O = 1.342 × 3 = 4.026

The whole number ratio, approximately, of Pb and O is 3:4, hence, their empirical formula is Pb3O4.

Explanation:

Answer:

37 L

Explanation:

Reaction is: 2 Al (s) + 3H₂SO₄(aq) → Al₂(SO₄)₃ (s)  +  3H₂ (g)

2 moles of Al react to 3 moles of sulfuric acid, in order to produce 1 mol of aluminum sulfate and 3 moles of hydrogen.

So ratio between aluminum and hydrogen is 2:3. We assume the acid is the limiting reactant.

2 moles of Al can produce 3 moles of hydrogen

Then 1.1 moles of Al, will produce (3 . 1 .1)/2 = 1.65 moles

If 1 mol of any gas, occupies 22.4L at STP

1.65 moles of H₂ may ocuppy (1.65 . 22.4) / 1 = 36.96 L ≅ 37L

If we had applied Ideal Gases Law → P . V = n . R  .T

At STP. we have 1 atm and 273 K

V = (n . R . T) / P → (1.65 . 0.082 . 273) / 1 = 36.9 L

Answer:

Q = 33105.6 J

Explanation:

Given that,

Mass of water, m = 88 grams

The temperature raised from 48°C to steam at 138°.

We need to find the energy required to raise the temperature. The formula for the energy required is given by :

[tex]Q=mc\Delta T[/tex]

Where

c is specific heat of water, c = 4.18J/g °C

So,

[tex]Q=88\times 4.18\times (138-48)\\\\Q=33105.6\ J[/tex]

So, the required energy is 33105.6 J.

The Northern Hemisphere is tilted toward the Sun in summer is the correct answer.I hope this helps

Explanation:

Day turns into darkness as the Earth spins, and summer turns into winter when the Earth completes its whole cycle. Therefore, the Northern Hemisphere is tilted toward the Sun in summer. The correct option is option B.

The circular motion of an item about its center is referred to as rotation. Things can spin in a variety of ways.  When a round, three-dimensional object rotates around an imaginary line inside of its center, it is a relatively common type of rotation. This focal point is known as an axis.

The Earth's rotation and revolution effect wind patterns, temperature, ocean currents, and precipitation, which together determine our local weather and the planet's overall climate. the Northern Hemisphere is tilted toward the Sun in summer.

Therefore, the Northern Hemisphere is tilted toward the Sun in summer. The correct option is option B.
