Lattice energy is an estimate of the bond
conductivity
group
length
strength

Explanation:

To solve this problem, we simply use the periodic table of elements which groups elements based on their atomic numbers.

The atomic number of an element is the number of protons it contains. The protons are the positively charged particles within an atom.

Now;

Noble gases  belongs to group 18

Alkali earth metals belongs to group 2

Halogens belongs to group  17

Alkali metals belongs to group 1

Transition metals belongs to group 3-12

Answer: I don't know if this helps but here's some information I think might help.

Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours. Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) and dividing each by the total number of cells you counted. How do cancer cells differ in total time required for mitosis? Cancer cells produce 117 minutes faster than regular cells. ... Normal cells require 640 minutes during interphase, cancer cells only need 380. For prophase, cancerous cells need 15 minutes less than regular cells. Another hallmark of cancer cells is their "replicative immortality," a fancy term for the fact that they can divide many more times than a normal cell of the body. In general, human cells can go through only about 40-60 rounds of division before they lose the capacity to divide, "grow old," and eventually die 3.

Answer:

A. The siding on a house buckles on a hot day

Explanation:

The key word in this question is EXPANSION. Without even knowing the siding expands causing it to buckle when it's hot, you can use process of elimination. It can't be answer B because watered down iced tea would most likely be as a result of the ice melting which is the opposite of expanding. It can't be C because air is not solidified and therefore can't expand. Lastly, D cannot be it because ice cream expands when cold, causing it to become hard. If it's not hardening then it's not expanding. This is also the correct answer on a p e.x

Answer:

PE = 73.58 J

Explanation:

Given data:

Mass of apple = 5 Kg

Height of tree = 1.5 m

Potential energy = ?

Solution:

Formula:

PE = mgh

g = 9.81 m/s

by putting values,

PE = 5 Kg × 9.81 m/s × 1.5 m

PE = 73.58 J (Kgm²/s = J)

Answer:

The volume in milliliters is 250mL

Explanation:

The volume of a rectangle is obtained using the equation:

Volume = Length * Width * Height

In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:

Volume = 5cm * 5cm * 10cm

Volume = 250cm³

1mL = 1cm³.

That means the volume in milliliters is 250mL

Answer:

[tex]\boxed {\boxed {\sf About \ 2.23 \ moles \ CH_4}}[/tex]

Explanation:

First, find the molar mass of CH₄

This compound is made of carbon (C) and hydrogen (H). Look on the Peirodic Table for the masses of both elements.

Now, count the number of moles in the compound. There is no subscript on C, indicating 1 mole. There is a subscript of 4 on H, indicating 4 moles. We must multiply the molar mass of hydrogen by 4.

Add the 2 masses.

Next, find the number of moles in 35.7 grams.

Use the molar mass of CH₄ as a ratio.

[tex]\frac{16.043 \ g \ CH_4}{1 \ mol \ CH_4}[/tex]

Since we want the units of grams CH₄ to cancel when we multiply, we must flip the ratio.

[tex]\frac{1 \ mol \ CH_4}{16.043 \ g \ CH_4}[/tex]

Multiply by 35.7 grams.

[tex]35.7 \ g \ CH_4 *\frac{1 \ mol \ CH_4}{16.043 \ g \ CH_4}[/tex]

The grams of CH₄ will cancel each other out.  Since there is a 1 in the numerator, we can also move 35.7 to the numerator.

[tex]35.7 *\frac{1 \ mol \ CH_4}{16.043 }[/tex]

[tex]\frac{35.7 \ mol \ CH_4}{16.043}[/tex]

[tex]2.22526959 \ mol \ CH_4[/tex]

The original measurement given, 35.7 grams, has 3 significant figures (3, 5, and 7), so we must round to 3 sig figs.

For this number, it is the hundredth place.

The 5 in the thousandth place tells us to round the 2 to a 3.

[tex]2.23 \ mol \ CH_4[/tex]

There are about 2.23 moles of CH₄ in 35.7 grams.

Answer:

2.5 kilometers

Explanation:

Given :

A chemical equation :

H₂O₂ → H₂O + O₂

Solution :

We can see that there are 2 oxygen atoms in LHS and 3 on RHS .

So, we can reduce the oxygen atoms to two in THS by just dividing it by 2.

H₂O₂ → H₂O + [tex]\dfrac{1}{2}[/tex]O₂

Now, multiplying both sides by 2, we get :

2H₂O₂ → 2H₂O + O₂

Therefore, the balanced chemical equation is 2H₂O₂ → 2H₂O + O₂ .

Answer: The box is moving downward with increasing speed.

Explanation:

The diagram models the forces acting on a box. 2N 2N- Box - 2 N 5 N .The box is moving downward with increasing speed best describes the motion of the box.

The normal force acting on the box is equal to and opposite to its weight. This term equals the force of gravity when the box is on a level surface. To calculate the normal force of the box, use our given mass and gravity's acceleration.

When an object interacts with another object, it experiences a push or pull that causes it to change state, either from rest to uniform motion. It is a magnitude and direction vector quantity.

A representation of the forces acting on the object. The object is represented by a dot, and forces are represented by arrows pointing away from the dot. Force diagrams are another name for them.

Thus, The box is moving downward with increasing speed best describes the motion of the box.
