Diploid cells have:
a. the regular number of chromosomes of the parent organism

b. twice the number of chromosomes of the parent organism

c. half the chromosomes of the parent organism

Answer:

For the most part, in mitosis, diploid cells are partitioned into two new diploid cells, while in meiosis, diploid cells are partitioned into four new haploid cells.The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred.

2.499 mol HCl

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

1.505 × 10²⁴ atoms HCl (Hydrochloric acid)

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

[tex]1.505 \cdot 10^{24} \ atoms \ HCl(\frac{1 \ mol \ HCl}{6.022 \cdot 10^{23} \ atoms \ HCl} )[/tex] = 2.49917 mol HCl

Step 4: Check

We are given 4 sig figs. Follow sig fig rules and round.

2.49917 mol HCl ≈ 2.499 mol HCl

Answer:

Volume of HCl require =  6 mL

Explanation:

Given data:

Volume of HCl require = ?

Molarity of HCl solution = 1.60 M

Volume of NaOH = 48.0 mL

Molarity of NaOH = 0.200 M

Solution:

Formula:

M₁V₁     =      M₂V₂

By putting values,

1.60 M×V₁  =  0.200 M×48.0 mL

V₁  =  0.200 M×48.0 mL/1.60 M

V₁  =  9.6 M .mL /1.60 M

V₁  =  6 mL

Answer:

The independent variable here is the types of soil

Explanation:

An independent variable is the variable that is not affected by the outcome of other variables in a given experiment. This variable is the variable that is intentionally altered/changed (directly or indirectly) by the researcher in order/expected to produce a result for the experiment. Thus, the independent variable here is the types of soil. This is because the soil was intentionally changed/varied by the researcher and it's expected to determine the heights of the bean plants grown.

Answer:

New volume V2 = 92.7 Liter (Approx)

Explanation:

Given:

V1 = 106 l

T1 = 45 + 273.15 = 318.15 K

P1 = 740 mm

T2 = 20 + 273.15 = 293.15 K

P2 = 780 mm

Find:

New volume V2

Computation:

P1V1 / T1 = P2V2 / T2

(740)(106) / (318.15) = (780)(V2) / (293.15)

New volume V2 = 92.7 Liter (Approx)

The final volume will be  44.69 L

Initial volume V₁ = 106.0 L

Initial pressure P₁ = 740.0 mm of Hg

Initial temperature T₁ = 45.0⁰C

Final pressure P₂ = 780.0 mm of Hg

Final temperature T₂ = 20.0⁰C

It is required to calculate the final volume V₂

The ideal gas equation is formulated as:

PV = nRT.

In this equation, P refers to the pressure of the ideal gas, V is the volume of the ideal gas, n is the total amount of ideal gas that is measured in terms of moles, R is the universal gas constant, and T is the temperature.

Applying the ideal gas equation considering the gas inside the balloon to be ideal, to get the new volume.

So, from ideal gas law, we get,

[tex]\frac{PV}{T} = constant[/tex]

where P = pressure, V= Volume, T= temperature.

So,

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

[tex]V_2 = \frac{P_1V_1T_2}{P_2T_1}[/tex]

On substituting the values;

[tex]V_2=\frac{106.0\times740.0\times20.0}{780.0\times45}[/tex]

V₂ = 44.69 L

Hence, The final volume will be  44.69 L

Answer:

-304.1

Explanation:

Just took it on Edge 2020

The enthalpy change for the target reaction is obtained as -304.1 kJ.

The Hess law of constant heat summation states that; the heat of reaction can be obtained as the sum of the heat of several reactions.

In this case, the enthalpy change for the target reaction can be identified as; -198.9 + 142.3 + (-247.5) = -304.1 kJ.

Explanation:

H₂O and CO are reactants in the following chemical equation which are water and carbon monoxide respectively.

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Explanation:

Answer:

(4) 266 moles

Explanation:

We have Dinitrogen Pentoxide N2O5

6.41*10^25 molecules are given

No of Moles of N2O5 = [tex]\frac{No of Molecules }{Avogadro's Number}[/tex]

                                     = [tex]\frac{6.41 * 10^25}{6.022*10^23}[/tex]

                                      = 106.5 mol

Now using Unitary Method

2 Mole of Nitrogen pentoxide require 5 mole of Oxygen to form N2O5

1 mole of N = [tex]\frac{5}{2}*O[/tex]

In 106.5 mole of N  = [tex]\frac{5}{2}*106.5[/tex] = 266.25 mole

So, 6.41*10^25 molecules of N2O5 will require 266.25 mole of Oxygen atoms.

Answer:

ur missing something`

Answer:

6

Explanation:

First, turn the mixed numbers into improper fractions.

4 2/3 = 14/3

1 2/7 = 9/7

Next, find the LCM of the denominators of the fractions.

3: 3, 6, 9, 12, 15, 18, 21

7: 7, 14, 21, 28, 35, 42

Then, we can see that 21 is the LCM of 7 and 3 so then we see how many times we had to multiply to get that number.

9/7 x 3/3 = 27/21

14/3 x 7/7 = 98/21

Last you just multiply straight across and simplify if needed.

27/21 x 98/21 = 6/1

6/1 = 6

Answer:

the second 1

Explanation:

Answer:

For some reason all of those look like they are true

1. Box A

2. Box B

Explanation:

Box A has the greatest mass. As mass is directly proportional to Work. ie. Work= Force * Distance and Force= mass* acceleration. So,

Work = Mass* Acceleration * Distance

Box B reaches the end first as according to newtons second law, acceleration is inversely proportional to mass.Since, box B has the less mass, it will have higher acceleration and cover more distance.(Distance is directlyproportionalto speed)

Answer:

n California there are two plates - the Pacific Plate and the North American Plate. The Pacific Plate consists of most of the Pacific Ocean floor and the California Coast line. The North American Plate comprises most the North American Continent and parts of the Atlantic Ocean floor. The primary boundary between these two plates is the San Andreas Fault. The San Andreas Fault is more than 650 miles long and extends to depths of at least 10 miles. Many other smaller faults like the Hayward (Northern California) and the San Jacinto (Southern California) branch from and join the San Andreas Fault Zone.

The Pacific Plate grinds northwestward past the North American Plate at a rate of about two inches per year. Parts of the San Andreas Fault system adapt to this movement by constant "creep" resulting in many tiny shocks and a few moderate earth tremors. In other areas where creep is NOT constant, strain can build up for hundreds of years, producing great earthquakes when it finally releases.
