Answer:

The offspring will all have red-colored flowers

Explanation:

A dominant character is one that is always expressed when it is present.

A recessive character or trait is one that is only expressed in the absence of the dominant character. Thus, when the dominant and recessive character are both present in an organism, the recessive character will be hidden while the dominant character will be expressed.

According to Menedel's laws of inheritance, in the cross between the dominant (RR) red-flowered plant and the recessive (rr) white-flowered plant, the genotype of the offspring will be as follows:

RR x rr = Rr, Rr, Rr,Rr

The offspring are all heterozygous for flower color. However, since red flower color is dominant over white flower color, all the offspring produced will have red-colored flowers.

Explanation:

Answer:

1. No reaction.

2. ZnCl₂ + H₂

3. CaCl₂ + H₂

Explanation:

1. Cu + HCl —> ___

From the reactivity series of metals, H is higher that Cu in the series and so, Cu can not displace H from solution.

Therefore, no reaction will occur.

2. Zn + HCl —> ___

Zn is higher than H in the activity series so, it will displace H from acid solution to produce hydrogen gas, H₂.

The balanced equation is given below:

Zn + 2HCl —> ZnCl₂ + H₂

3. Ca + HCl —> ___

Ca is higher than H in the activity series so, it will displace H from acid solution to produce hydrogen gas, H₂.

The balanced equation is given below:

Ca + 2HCl —> CaCl₂ + H₂

Answer:

2Mg + O2 → 2MgO

Explanation:

Answer:

Standard acid-base reaction in two stages:

Na2CO3 + HCl → NaHCO3 +NaCl

NaHCO3 + HCl → NaCl + CO2 + H2O

If only a small quantity of acid is added (and the overall solution remains above pH 7), the reaction would stop at stage 1 and you’d be left with an aqueous solution of sodium chloride and sodium bicarbonate. Adding more acid would lead to the bicarbonate being converted to carbon dioxide and water, with the CO2 coming out of solution as a gas and more sodium chloride being produced.

Answer:

19.32 g/cm³

Explanation:

The density will remain the same no matter how many times you cut the gold.  The density is g/cm³ or g/mL.  Density is essentially how many grams 1 mL of a compound weighs.

Answer:

[tex]\boxed {\boxed {\sf 19.32 \ g/cm^3}}[/tex]

Explanation:

Density is the mass per volume (g/mL or g/cm³). It is an intrinsic property. This means it is not dependent on the amount and all samples of the same substance have the same density.

Therefore, if a piece of gold has a density of 19.32 grams per cubic centimeter and it is cut in half, the two pieces will have the same density.

Answer:

The temperature will be 384.7 K

Explanation:

Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure, by means of a constant of proportionality that is applied directly. For a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement of the gas molecules. .

In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T} =k[/tex]

Having an initial state 1 and a final state 2, the following is true:

[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{33.9 L}{285.4 K} =\frac{45.7 L}{T2}[/tex]

Solving:

[tex]T2=45.7 L*\frac{285.4 K}{33.9 L}[/tex]

T2= 384.7 K

The temperature will be 384.7 K

Explanation:

because it generates power through fission

Answer:

B.

Explanation:

The atomic model represents the position of the sub-atomic particles. Model A was proposed after Rutherford's scattering experiment where the positive particles were deflected in the middle. Thus, option A is correct.

Rutherford's atomic model proposed the presence of the positive nucleus in the middle of the atom while the electrons surrounded them in their orbitals with a negative charge.

He performed the scattering experiment where alpha particles emitted by the radioactive element were used to locate the positions of the electrons, neutrons, and protons.

According to the experiment, model A, best fits as the nucleus made of protons and neutrons takes the center of the atom with negative electrons surrounding them. The nucleus is small as compared to the entire atom.

Therefore, option A. model A best proposes Rutherford's model.

Answer:

CO2

Explanation:

CO2 or carbon dioxide is produced when iron is extracted from its ore. Carbon monoxide Co is used as reducing agent in iron extraction. In this reaction iron ore is reduced to iron and CO is oxidized to CO2 or carbon dioxide which is released in the process. There extraction of iron is redox reaction.

Answer:

peanut butter

Explanation:

because you have 10 pieces of bread, 4 tbs of peanut butter, and 20 tbs of jelly, meaning you can make 5 sandwwitches with the bread, 4 sandwitches with the peanut butter, and 10 sandwitches with the jelly. so you dont have enough peanut butter to make all the sandwitches

According to the given scenario,  If one have 10 pieces of bread, 4 tablespoons of peanut butter, and 20 tablespoons of jelly, the limiting reactant will be peanut butter.

What is a limiting reactant?

The reactant that gets consumed first in a chemical reaction and result in limiting the formation of product is referred to as a limiting reactant.

According to the given scenario, the quantity of peanut butter will get consumed first so it will act as a limiting reactant.

Answer:21 moles of PbCl2 formed

Explanation: 3Pb(NO3)2(aq) + 2AlCl3(aq) --> 3PbCl2(s) + 2Al(NO3)3(aq)

14 moles AlCl3 x 3 moles PbCl2/2 moles AlCl3 =21 moles of PbCl2 formed

The number of moles of PbCl₂ produced when 14 moles of AlCl₃ are consumed in the reaction is 21 moles

3Pb(NO₃)₂ + 2AlCl₃ —> 3PbCl₂ + 2Al(NO₃)₃

From the balanced equation above,

2 moles of AlCl₃ reacted to produce 3 moles of PbCl₂.

From the balanced equation above,

2 moles of AlCl₃ reacted to produce 3 moles of PbCl₂.

Therefore,

14 moles of AlCl₃ will react to produce = (14 × 3) / 2 = 21 moles of PbCl₂.

Thus, 21 moles of PbCl₂ were obtained from the reaction.
